“Allmaster did some foundation repair. There was a slope and some cracks in the foundation, and the job worked. They were honest, on time, and professional. I’d give them an A+.”

“Allmaster put some high beams in my basement to hold back the retaining wall. They were very professional, and I would use them again. I’d definitely recommend them. They get an A.”

“They were wonderful. They worked on our basement drainage and foundation. They were very up front, and they did everything that they said they would do. We were pleased—A.”

“They did waterproofing, and they did an excellent job. It needed it really bad. They did an awesome job. I would grade them an A+. I have already recommended Allmaster Home Services.”

“Just very professional and clean, very clear expectations, and work site was clean. Everything was great. They were doing waterproofing and drainage. I would grade them an A+.”

“They kept me well informed as to what they were going to do even though there were a couple of hiccups on the day that they were supposed to arrive, but it wasn't their fault. It was a lot of traffic coming across the bridge coming to Centreville, so they called me to let me know they were going to be late. Once they got here, they got to work very quickly and did not stop until the job was completed. They were doing both foundation repair and waterproofing. I'd give them an A+.”

“They're the only ones that were actually able to diagnose the problem. They fixed a drain on the bottom of a stairwell that goes into the basement. They were able to redo it and make sure water doesn't flood up the place. They redid the pad, and put a larger drain in, and connected it to the sump pump. I'd give them an A+.”

“I liked how thorough they were in the preparation and evaluating what needed to be done and how professionally they went about doing it. And I liked the fact that the finished result was very professionally done, very well done. They met my expectations and I felt really good about the way that they approached the whole project, so much so that I asked them to do some work that doesn't necessarily fall within what they advertise, just because I like what they did. I wanted to see if they could help me with a couple of other projects which they did do and they did those satisfactory as well. It was essentially a waterproofing—it was not a foundation repair. We had water leakage after having installed an outdoor water line. A main line coming to the home had been installed two years before and the people who installed it had left it where it leaked into the basement. The basement is a hundred year old basement—I don't see any signs of any water damage other than what had happened after that. I had a number of different plumbers come out and try to do things for it, and they were unsuccessful. Allmaster was able to design a solution, put in a French drain, and it has worked flawlessly since they did it. I'd give them an A+. Everything they did was very professionally done. I never had a single issue with any of the things that they had done.”

“They did foundation waterproofing. They did their work fast and how they said they were going to do it. There were no unexpected problems or deals that came up. They were very clear about what they were doing. Overall, it was a very positive experience. I'd give them an A overall.”

“They had very clear communication, and arrived when they said they would for appointments. They did waterproofing for me, and roofing. I would grade them an A. They haven't finished yet we are in the middle of a project. They were always where they said they would be.”

“I think I had them working my basement. They were here and out fast, did the job, and got out. It was waterproofing, they put a French drain in for me. I would grade them an A. I haven't had any problems with it. They cleaned up behind themselves.”

“There were some mistakes made the first time, but they were quick to come out and fix things. They were waterproofing my basement. I'd give them an A. They fixed it. It just took a couple times.”

“They did waterproofing for me. They were very professional, came when they said they would, did the job, did a good job, and financial things about it were all done appropriately. I'd give them an A.”

“They ended up replacing some drainage piping in our basement where we were having a moisture problem. They seemed very knowledgeable, professional, and explained to us what they were doing. I would grade them an A.”

“They waterproofed my basement. They're a family business. They were quick, efficient, and they were clean. They resolved an issue that we had at the end very quickly and very satisfactorily. I would give them an A. I've actually already recommended them to someone.”

“So far, so good. I liked the way they hooked the system up for me saying it would be working properly, and it looks like that's taken care of the problem I was having. They did outside waterproofing for me. I'd give them an A-.”

“They were excellent, and I don't have any complaints.”

“Their work is excellent, no complaints. I'm likely to recommend them. They did waterproofing.”

“Allmaster was excellent. They worked on our basement, and I have no complaints. We would recommend them.”

“They fixed a retaining wall in the backyard. The guy was great, very thorough, and he cleaned everything, from beginning to end. Everything was covered, just as I expected. It was a great job and great work. I will probably be using them again to remodel my bathroom. I would grade them an A+”

“They did some foundation work. They said they would do it in a day, and they did it in a day. I would grade them an A+”

“They were great. I would grade them an A.”

“They did the basement. There was a horizontal crack along the wall, and they fixed it. The workers just came and did their job. I would grade them an A. It's very likely that I would recommend them to friends and neighbors.”

“They put in a basement drain tile for me and waterproofed the basement wall. The owner knew exactly what the problem was and resolved it for me. I would grade them an A.”

“They fixed a basement wall that had a water leak. I liked that they were patient, kind, and quick. I would grade them an A.”

“Overall, I had a good experience.”

“They did some waterproofing and wall replacement, and their promptness and professionalism were great. I would grade them an A.”

“They did a French drain and installed a sump pump. They were on time, they were neat, and they did what they said they were going to do. I would grade them an A.”

“They were good. They did some concrete work outside my house. They got in, got out, and I was done. I would grade them an A.”

“They cleaned up the damage from some water that got in my basement from the rain. This is the second time I have worked with them. I like that they're a family-run company. They were personable. They tried to get over as soon as I needed help. And then it didn't work; it still leaked. They came back, but it still leaked. So then they came back a third time, and they used a totally different thing, and it worked. I liked that they didn't leave me hanging.”

“I'd give them an A.”

“We had them redo the waterproofing system in our basement and some foundation repair. The owner, Nick, is great to work with. He always has thorough answers. I would grade them an A- because we had some issues with the contractor that was doing the painting.”

“They were tremendously hard workers. They put a sump pump in my basement with a drain. I would grade them an A.”

“Allmaster dug some holes in the basement for some drainage pipes—so that the walls could drain. They had great personality, and they were prompt and on time. I would grade them an A, and I have recommend them.”

“Over a year ago, we had a townhouse with some cracks in the basement wall. They had to drill into the cinderblocks and put in support to shore up that wall. It was the outside wall, and they were really good. We were selling our house, and they got it done quickly. I would grade them an A.”

“Allmaster did some waterproofing around the foundation. They did a good job, they did it quickly, and then they were gone. They get an A across the board. I've already recommended them.”

“They did some waterproofing and stopped a leak in my basement. They were responsive. They tried one thing, but it didn't work, so they came back and said, 'Hey, we'll try something else, and it'll be at our expense.' I'd give them an A for that. The only issue I had was that I ended up having to put up a mud barrier because the contractor who came in tracked in some mud.”

“I had an area that wouldn't drain, so they dug it up, put a new sump pump in the basement, and installed a drain. They were friendly and fast—I called for an appointment and got it the next day. The workers were all friendly, and it was a nice experience. I would give them an A+ on everything; they were great.”

“I had a leak in my basement, so Allmaster did some waterproofing. They installed a French drain system. They were prompt and very professional. A+.”

“Allmaster did the waterproofing, and I was very happy with them. I'm interested in using them again for another project. They're A+.”

“They did some waterproofing. They were very courteous, they had good manners, and they cleaned up their mess behind them. They were very professional. I would say they get an A+.”
