“We've been working with JES for several years now with our foundation and our encapsulation under the house. They've always done an excellent job. I'd give them an A+.”

“It was absolutely positive. They saw that a little bit of extra work needed to be done and they stopped what they were doing, gave us a quote, did the job right there and then, and made sure everything was good before they left. So far, everything has worked great. It was foundation repair. I'd give them an A.”

“JES worked hard. They were here on time and worked the whole time. They were productive. They were doing foundation repair, and they did excellent work. I had no complaints. I would recommend them.”

“George, the general manager, has been very, very helpful. It's been going on for a year and a half. Initially, they did foundation work and they did insulation. I believe they checked the part of the foundation. I don't know what to call that, but they did their part. I think that once they got focused on the job, they did a great job. I'd give them an A. I'd recommend them.”

“They did a good job. They added five more footers around the house and put tacks there. I'd give them an A+. I would recommend them.”

“They were just very easy to talk to, very willing to answer questions, pleasant, friendly and professional. It was foundation repair. I'd give them an A+. I have no way of calculating the quality of work.”

“It was definitely positive. I liked just how professional they were. They did keep me in the loop as they were doing the job. It was foundation and a jacking up of the center of the house as well. I would say probably an A. I've already recommended them to a couple of people.”

“Nothing in particular I liked about them. They were doing foundation repair. I'd give them an A. It works fine. I would recommend them.”

“Nothing in particular I liked or disliked about them. They came, did their work, and that was it. It was foundation repair. I'd give them an A.”

“Overall they were friendly and attentive. They did one foundation wall reinforcement. I would say it's an A.”

“The crew that they sent was very professional, very knowledgeable, and quick and conscientious. They were doing foundation repair and fireplace related to foundation. I'd give them an A. I would recommend them.”

“They were very thorough, friendly, and went through the whole scenario of what was really going on. They told me my options, what they would do today, and the potential downfall if I don't do it. JES just kind of walked me through the entire opportunity to get everything repaired. It's a rental property of mine. It was five joints that needed to be replaced due to dry rot, water damage, and termite damage. I'd give them an A. I would recommend them.”

“They came in. They described the job and they did it. They told us what not to do as far as putting the old cement. They were very professional. It was foundation repair. It had a very small crack that was just seeping water. I'd give them an A.”

“I called JES Foundation Repair because I had a wet area in the middle of a basement room, and there was no leak in the ceiling. I was very impressed with the technician that came to evaluate the problem. He was very knowledgeable, quickly diagnosed the problem, and was able to explain everything in layman's terms.”

“The crew who came out did a fantastic job raising our sunken walkway without having to destroy it and pour new cement. They blended everything so it looks like nothing ever happened. They left our property very neat and clean. We are delighted with this company. If we ever need anything again that this company does, we will call them first—A+.”

“I loved the JES Foundation Repair service personnel and workers. They did a great job, and I would highly recommend them to friends and family.”

“I don't really know how to assess foundation repairs, but JES's piers seem to have reversed some settling of my slab foundation and the company was very easy to work with.”

“Very knowledgeable staff and expert work. Would definitely use their services again if needed.”

“We had a problem with the foundation of our chimney that caused it to pull away from the house. JES used the push-pier system to reinforce the foundation. Their process straightened the chimney and provided a secure foundation to solve the problem. We were very satisfied with the results and the expertise of their employees.”

“I believe they did a good job but the repair has had to be redone a number of times due to continued settlement. But, they always came out to try and correct the problem.”


“JES Foundation did a great job. Even a month afterward when there was some additional settling, they came back under warranty (no charge) and fixed it. Employees were nice and knowledgeable. Worked hard on a very hot day.”

“The?service representative and repairman were outstanding.”


“This company is professional, efficient and thorough. They provided all the expertise to correct our foundation problem. After all the digging, removing flower beds and trenching in the yard to provide run-off for the drain, we were extremely pleased when the crews returned the area to its original appearance, flowers and all, to look as though the area had never been disturbed. We would highly recommend this company and the young people who do the work. They were great!”

“We had JES out to put 10 piers in close to 10 years ago. We did not hesitate to call them to put in 3 more a couple years ago.”

“We had a 5' X 13' concrete slab that had sunk 1.5' at one end and become a tripping hazard. A JES engineer came out to inspect my work request, explained the options and recommended the most appropriate action for our situation. The result was exactly what we hoped for...and 1 year later still looks great. The company also tried to level a poolside concrete slab, but stopped trying when their efforts actually made the poolside slab tilt even worse.”

“I had wall anchors installed for a retaining wall. Everything about the installation was smooth and uneventful. However, the anchors are pretty ugly and need covers to be presentable. Getting the anchor covers (which were selected weeks prior to the job) took many weeks more to be attached. Disappointing ending.”

“The crew did a good job, but they didn't do everything they were supposed to. They lifted the sidewalk, but not the driveway.”

“As I knew from 20 years ago that my kitchen floor sagged, and there being a crawl space below, and I was now again remodeling the kitchen again, I decided it was time to fix the sagging floor. They came over right away, I had to wait a few weeks, but they did a beautiful job, added 3 more posts to hold up the 22-foot long middle section of my split level home, and added all new insulation under the floor, put down beautiful protection from crawl space dampness. Looks and feels nice and dry now. No delays in getting work done, etc.”

“The JES representative was great, they arrived on time and the work was performed as contracted using the PolyLevel technique. I could actually feel the difference right away. However, within several months it seems my sloping porch is off, like it sank down again. I've called a couple of times to request a follow-up but no response yet.”

“Did a very good job and found other issues from a previous contractor who made a mistake that caused us to use JES.”

“The only reason for a less than A was that the repair took two visits. The first time, the cement porch area was not lifted high enough. Second time around was fine. The guys doing the job were great.”

“The crew that was sent out were very professional and helpful, going above and beyond their duties, since one of my cats got under the house and they helped me get it back out. (Thanks Manny) I have already told a couple of other people about the job they did and would definitely recommend them again.”

“When I called the office, the staff was very professional and patient, made sure I was taken care of and quickly scheduled me for service. Received an outstanding level of service from Demetruis and his crew. They quickly diagnosed the problems, corrections were made immediately. They also took the time to educate me on the process as they were working which was greatly appreciated.”

“My husband and I are satisfied with the work that JES performed.”

“They secured an eight-foot alley wall. They dug a trench, drilled holes in the alley wall for retention rods and weeping holes, installed plates on either side, screwed them together, and filled the trench back in. The work was performed in two days. The backyard had minimal disruption. The work area was kept clean and free of debris. They left the jobsite in excellent condition. They provided a torque wrench to maintain tension on the bolts. They were courteous and professional on the phone and in person, and the best part is that they fixed the problem.”

“JES installed piers to close up cracks in a brick wall. The experience was positive. The representative was professional and knowledgeable. They said that if any adjustments to the piers are needed in the future, they would do it for free, which gives us peace of mind.”

“JES installed underfloor jacks to stabilize and lift the house, and they encapsulated the crawl space. The workers were polite and professional, and the work was completed on schedule. The quality of work was good.”

“JES Foundation Repair installed resistance piers to stabilize the chimney whose foundation started to lean away from the house causing the chimney to lean away from the house. JES provided a price quote and engineering drawings, and they answered all of my questions during a visit to my residence. The work crew was knowledgeable and answered all of my remaining questions while performing the work. The crew cleaned up after themselves and replaced the dirt that was dug up around the chimney foundation.”

“They installed six SmartJacks under my house to support my sagging center beam. It was positive because they did exactly what they said they were going to do when they said they were going to do it. I didn't have to contact them again after they left (very unusual for me).”

“They did Kevlar fiber bands implanted in the basement cement block wall. They were easy to deal with. It was fairly clean work.”

“JES performed a foundation crack repair and partial waterproofing system on my home. The crack was stabilized by carbon straps. My overall experience was positive. The consultant and repair crew were professional and seemed knowledgeable about the issue and performing the repair.”

“They did a floor joist repair. It was positive, and they complied with the job in a timely manner.”

“They placed steel rods through the wall on one end of my house so that we could pull the wall outward, as it was pushing in somewhat. They came on time, performed all work in a workmanlike manner, kept us informed along the way, and did a great cleanup and reseeding on the lawn.”

“We were losing a bay window in our 1936 historic home. As the foundation beneath it sagged, it was pulling away from the house, with a larger gap at the top and a smaller one at the bottom. JES jacked it up and poured new footings, fixing the problem. They were able to do this without significantly hurting a half dozen very large azaleas adjacent to the bay window and without tearing up the lawn.”

“JES raised the step at my front door about four inches. They came when they said they would, did a little more than they were contracted for, and were very nice to interact with. What's not to love?”

“They installed four push pins to lift and stabilize the foundation and installed six wall anchors to straighten and secure. I believe that working with JES is more of a partnership in securing the foundation of my house. Besides the actual work, which was done efficiently and professionally, they offered advice, tips, and tricks to prevent other foundation issues (fixing the gutters).”

“They installed three helical piers under my front stoop for the first job, done several years ago. They installed five wall anchors on my front basement wall. It was very positive. They did what was needed in a timely and professional manner.”

“JES repaired two cracks that appeared in our foundation less than two years after the house was built. The builder wanted to do a Band-Aid repair that we weren't happy with, so we obtained input from JES and one other company and decided to go with JES because of their professionalism and knowledge.”

“JES installed 12 SmartJack support posts in my crawl space to correct foundation problems in my home and to prevent foundation issues in the future. In addition, JES installed their Clean Space encapsulation system in my crawl space to prevent humidity by isolating my house from the earth. My experience with JES was positive because of the professionalism of the company. Customer satisfaction, honesty, hard work, and being courteous to the customer are qualities are not found very often in businesses these days. From the people scheduling the appointments, to the on-site visit, to the actual work being done, every JES employee that I encountered was knowledgeable, professional, polite, and had my interests in mind. The bottom line is that they did exactly what they said they were going to do—no bait and switch tactics.”

“They installed supports to correct a leaning chimney. The technical sales rep was thorough and efficient. The work crew was very careful and courteous.”

“They did hydraulic pylons to jack up a sinking foundation. They were very knowledgeable and experienced at their work. There was some miscommunication at first between the project manager and the crew chief when the crew chief arrived on where the pylons were supposed to be placed, but a quick call got that straightened out. They were quick and explained the whole process, and they were fairly good about cleaning up after they were done.”

“They did an installation of multiple basement support beams. They were professional, clean, and conscientious.”

“They installed push piers to raise a brick wall and to straighten the chimney. The wall was only slightly raised, and there is no noticeable difference in the chimney. I presume, though, that further sinking will be eliminated. The work was done in a timely manner. The workers were polite and hardworking.”

“My basement wall was collapsing, so JES put up braces to fix the problem and hold it up. My experience was positive because I was informed on what was going on at every step being done.”

“JES encapsulated our crawl space and installed a drainage system to prevent a recurrence of our moisture problem. The people were the most professional folks who have ever done work in our home.”

“JES was waterproofing my crawl space. The workers were outstanding and did a wonderful job at removing the old debris from the crawl space—outstanding workers.”

“JES performed an assessment of my father's home for basement foundation moisture issues. The process to purchase the moisture solution and have it installed was seamless.”

“The foundation wall was settling. JES shored up the wall to keep it from settling any further. The folks performing the work were very professional. They are experts at what they do. I highly recommend these folks for foundation repairs.”

“JES figured out what was wrong and told me how they'd fix it. On one corner of the house, the foundation had sunk and caused some cracking and stuff. They jacked that up. They did it for the price they said they'd do it for, and it was well. I'd say that the company was an A.”

“JES Foundation Repair fixed a leak in a cracked wall in the basement with no problem. The salesman was good; he knew what he was talking about. I didn't have any callbacks, and I was very satisfied. I'd give them an A+ rating.”

“What we liked was that when the engineer came to the house, he showed us where we could put things and where we should not put things. It was explained very clearly so that we both understood it. Then when the workmen came to do the work, we felt that the workers, especially the head person in charge, were very honest and responsible. They seemed to work very hard and really want to do a good job. We were very pleased with them. They deserve an A.”

“JES Foundation Repair reinforced the foundation two years ago. They did the work that they were contracted to do. They were courteous and efficient. I'd probably give them an A.”

“They put a in French drain in, a sump pump, and a moisture barrier, and they elevated the house. Their timeliness made it a positive experience. The workers were courteous, and they worked very quickly and efficiently. I chose them because of a previous experience. I would give them an A grade.”

“JES Foundation Repair a good company. They did a good job. I would rate them as an A because they were great.”

“I had a crack that was leaking in the basement of a three-story townhouse, and JES patched it up for me. They were very personable, and they seemed to know what they were doing. They came when they were scheduled to come. They made it very easy. They deserve an A.”

“JES Foundation Repair put in a drain system because I had a leak in my foundation. The salesman wasn't pushy, and the workers that came out were fine. I'd give them an A.”

“They replaced a drain underneath my basement floor—it was an outside wall drain. They did the job that I wanted done. They were nice, timely, and pretty clean. I would rate them as an A.”

“The fireplace foundation had broken away, and it was beginning to lean a little away from the house. We were afraid it was going to tumble or fall over. JES came and jacked up the front corner, which was the farthest away from the outside, and they pushed it all back up against the house. They said exactly what they were going to do, and then they did exactly that. I'd give them an A.”

“I liked their presentation when they came and told us what they were going to do, and I liked their people in general. They were very respectful and willing to work around my schedule. Their work was good, too; I have no complaints about their work. I would give them an A.”

“They installed a waterproofing system in the basement. They worked hard, and even though it was a really messy job, they did such a good job of getting it all done and put back together in one day. I didn't have to have the work dragged out for days. It worked out great. I didn't have any issues, so I'd give them an A.”

“After the earthquake damaged the foundation, JES came in and stabilized the foundation. They were able to tell me what the solution was and convince me that their solution would be acceptable. They get an A rating.”

“JES Foundation Repair replaced or repaired a joist in my basement or on the second floor. They did what they said they were going to do. They got in and got out, and it was done well. I would give them an A.”

“JES did a drain tower and support from the basement. The work was clean and well done. I'd grade them as an A.”

“They put in sump pumps to take out the water that was underneath the church's basement and in the walls. We liked the fact that the system worked and did what it was supposed to do. I would give JES Foundation Repair an A.”

“They waterproofed my basement. They did the job, and they seemed to do it well. I can't compare it to anything because I haven't this type of service done before, but they kept my house very clean. They protected everything with plastic. It looks good, and I haven't had any problems since. We were pleased. They earned an A.”

“JES Foundation Repair did a pretty good job, and they seemed very nice. I'd give them an A.”

“They did the foundation work and put in my sump pump with a French drain all the way around. It took care of the water coming in the house. I still think there's an outside problem, but that, of course, wouldn't be their territory. They did quick and good work, and they did a good cleanup afterward. I liked their customer service, too, like when speaking with them on the phone. My dad might have used them and recommended them. I'd give them an A because it was really good.”

“They put a dehumidifier in our basement, and they hung plastic on the basement walls to prevent moisture. We'd already had the French drain installed a couple of years ago. I called them, and they called me within an hour or so to set up an appointment. We were very happy with their expertise and what they said they could do to prevent the water from coming into the basement. The people who did the project were very accommodating and very nice, and they did a very good job. They didn't get everything done in one day, and it took them about a week to get back again, which was a disappointment. I'd give them an A.”

“JES Foundation Repair did basement waterproofing. There were some complications when they were doing the job, but they absolutely stuck with it until it was perfect. They deserve an A grade.”

“JES did a very good job. They installed six foundation piers. They were extremely neat about it. We had a problem with erosion that washed out some dirt under the foundation. So in order to stabilize the house and be sure we didn't have future problems, they had to install those piers. The crew was very reliable and did a super job. I'd give them an A+.”

“JES did a great job. I have a really big garage, and it fell on one side, so they had to jack the foundation up. They leveled the structure, and it's been fine ever since. It was a great crew, and there was no mess when they left. They're excellent—A+.”

“JES was very professional. I had a cracked foundation where the corner of my house was sagging and my chimney was falling off the back of my house. They fixed both of them—they did great work. If I had foundation work, I'd call them in a heartbeat.”

“The estimate was correct. The people who came were extremely efficient and extremely courteous. The work was very high quality, and they left the job site very orderly, very clean. There was nothing not to like. They installed one of the foundational drainage systems that they do. So, they had to rip up a bunch of existing basement walls, carpets, and baseboards. Under the foundation, they saw the system and tried to put it back in order. I don't think there's anyone else in my area that even installs that kind of system—JES is the only one in the area that has the reputation for working with those kinds of systems. It's kind of a specialty system. Everything was an A+.”

“They did a great job at my house. They started the work when it was pretty cold out, and they did a phenomenal job. There was a little issue, and they came back and resolved the issue very quickly, with no hassle and no extra money, because it was an issue on their part. They came back and resolved it, and my house has been dry, so I don't have a problem at all. I'd give them an A, because the work that they did prior to prep for the job was amazing.”

“They know what they're doing for one thing, and they're experienced. I would say they did an excellent, quality job, they're always friendly, and that's it. It was a year and a half ago. So, they put in a whole drainage system, and then they do this check up every once in a while. They're very fine. They were excellent at the beginning, when they brought the system in and when they checked everything out, like filters and all that. So, they're checkup was great. I'd give them an A+—they were great.”

“They did as they said they would do, they were professional, and they did an excellent job. They sealed up my crawlspace. The workers were courteous and efficient. I brought them in to talk with them, and I thought that they could do the job and they did. I'd give them an A or an A+.”

“The crew was absolutely excellent. There were three guys. There's a leader and two guys that came to help him—they were very professional. I appreciate it when guys take care of the place. They made sure that they didn't mess up my property. They cleaned up. They did everything really nice, and I appreciate it, and I let them know. They put in a sump pump and drainage all around my basement. Some people had some work done with them and liked them, and I called them and had them come in. For the company, I'd give an A. For the crew, I'd give an A+.”

“I was impressed by their timeliness in the completion of the job. The time line that they discussed with me, they followed that to a tee. That's the key. They waterproofed the crawl space in my foundation area. I'd give them an A.”

“I absolutely love them. I like everything about them—from the salesman who first came to the house and went over the whole work that needed to be done to the people that came in to do the work. We did not have a bad experience at all. They waterproofed our basement. I'd give them an A all the way.”

“I liked the professionalism and knowledge of the service representative. They reinforced a basement wall. The workers were courteous and efficient, as well. I thought that they offered the best engineering solution. I would give them an A.”

“They were there when they said they would be there, they did the job, and they were gone. They were very neat. They put in a sump pump. They were courteous and efficient. I think they are an A—they're excellent.”

“They were on time and did the work to my satisfaction. They put supports under my foundation and also put in a water drainage system. I'd give them A+.”
