“We were very satisfied. Very reliable, they showed up on time. They gave us all the information, answered all the questions, they made recommendations, they gave us the cost estimate and stuck to it. They did plumbing, a gas line on the balcony to our grill and they did some electrical work. They exchanged a plug. I think that was it for last year. I would give them A+. I really don't have any complaints.”

“I am satisfied. On the electrical, there was a problem afterward, but they came right back and repaired it at no charge. The box that they used was an outdoor box and it got wet and shorted out. They put a different kind of outdoor box on it, and it's been fine ever since. I would give them an A rating. They were great. I would highly recommend them.”

“They were real super clean. They explained everything that they do. They are a little bit expensive, but they got the job done. They replaced the switch on the water heater. No electrical work was done. I would grade the overall experience with a B+. They were probably more expensive than what I was expecting. I would recommend them.”

Review by

“They were very responsive. They corrected the problems that I had—there were a few problems. They were responsive to my situation. They repaired significant plumbing issues. They repaired the pipe from the property to the city line. I would grade the overall experience with an A+. I would highly recommend them to a friend.”

Review by

“We are seniors and the high cost bills is not much help to us. They did plumbing work for us, on the outside. It backed up when you flushed the toilet, it backed up into the shower. I would grade the overall experience with an A+. They were nice people. They were very friendly. I would probably recommend them to a friend.”

Review by
06/21/2017

“They did the job right. They did the plumbing on our kitchen sink, and they went into the attic and fixed the thing that puts the water through for the air conditioner. I was putting in a new sink, and they put the faucets in for me. I would grade the overall experience with a B. They could improve their services because they could have a lower price. That would be my only complaint. I would not recommend them to a friend because they are too expensive.”

Review by
06/21/2017

“It's a professional company. You can depend on them to come on time, and they always have someone picking up the phone, and I like that. I think it worked out. I don't think there were any more problems with the toilet. And they did some work on the sink upstairs. They get an A-. It was quite pricey. I don't think they didn't use slip covers on their shoes. I would highly recommend them.”

Review by

“They sold me a hot water heater that I didn't need. I had a second plumber come in and put in one. They said was faulty; it wasn't, and I had to pay another $1,200 to get it re-installed. It's been sitting in my garage—and American Express is holding the payment—but I've been trying to get them to credit it, so that it doesn't pop up on my bill again for about three months. I'm ready to call everybody that they do business with, like the radio stations. I'm just ready to push it forward if they don't call back. It's been extremely time consuming and frustrating. I even thought maybe I was mistaken, but no, they ripped me out. It's absolutely true; I've got it all documented, and no one there has fixed it—and they've had about three months to do it. So, I cannot say in more strong terms, I will never do business with them. It was a tankless water heater installation. I would grade the overall experience with the lowest grade. No one there has been willing to make it right. And I've gone pretty far up the totem pole now; this is my third person I'm talking to now. This one was very earnest, very apologetic, very helpful—but he still has not taken care of the problem. I would never recommend them.”

Review by

“They were great. The men that came in were very professional, and they told me exactly what they were going to do, what door they were coming in, and when they were coming back. I mean, they told me everything I needed to know. I wasn't leery about any of them. They were professional. They knew what they were doing. They're great. I used them for my air conditioning, and they've done plumbing for me. I would rate the overall experience with an A+. When I was having air conditioning done, we had scheduled two or three appointments, and they would call and would tell me why they weren't going to be here because older people were having troubles with their air conditioners, and they felt like they needed to do older people first. I said no problem, that's just exactly what we need. I would highly recommend them to a friend.”

“I got a really high estimate, but I guess that's to be expected when you're dealing with a plumbing job. I had a leaky faucet, so the fixtures were replaced. I would grade the overall experience with a B. Because you could get this done, but your problem may not be fixed; you may spend a lot more money to do a lot more extensive work. The company is willing to bend over backwards to help you, but you need to be in the financial position to do what they recommended. The quality is something I have to see down the line. The funny thing about plumbing is that it would work for a moment, and then you can have that same problem reoccur because that's the same problem I've had in that house since I purchased it, so I can't comment on that for right now. I would not recommend them to a friend.”

Review by
06/21/2017

“It went both ways. At first it was negative, then it became positive. I don't know how to explain that. They messed it up at first, but then they fixed it and everything came out alright. They did some sewer plumbing for me. I'd probably give them a B. I've already been through this with them, but they just need to tell people the truth. They weren't very truthful about when the job was going to be done. They promised it one day, and it was two days later before they got around to it.”

Review by
06/21/2017

“They were quick to respond. They cleaned out our kitchen line. I think it was my kitchen line, the main that went out, that was clogged. It was excellent, with no problems. I'd be very likely to recommend them to a friend.”

“We had a good experience. The gentleman was on time, friendly, and efficient. He just did a minor little plumbing leakage in the sink. It was a good experience. Excellent.”

Review by
06/19/2017

“That was a while back. They were fairly responsive. The guy that actually came out did a good job explaining what the issue was. They came out to examine a leak we were having and do kind of a minor repair to fix the leak. It was a leak in our bathtub that was causing water to come downstairs. I would grade them as an A.”

Review by
06/14/2017

“I felt like the technician knew exactly what he was doing and what he needed to do. He was fine. He did plumbing for me. I would grade the overall experience with an A+. It was fine, it really was. I have absolutely no complaints. I would highly recommend them. The only problem I have is that they are expensive.”

Review by
06/14/2017

“They were very thorough and explained everything that was going to happen. Most recently we had an electrician, but we've had a plumber and an electrician in the past, and everybody's been very professional and very good. I would definitely say it was A+ work. We have recommended them.”

Review by
06/14/2017

“I wasn't really there while they were there. It was an easy process. It wasn't difficult or anything. They replaced my plumbing line. I'd give them an A+. I haven't had any problems with it. I guess I really won't know if it's all fixed until I have any issues, but I haven't had any.”

Review by
06/14/2017

“It wasn't anything major that they were doing. It was an easy fix. They were just looking at a leak that we had underneath our dishwasher. I would give the overall experience an A+. Again, it was nothing complex, all they had to do was tighten a pipe. I would recommend them.”

Review by
06/14/2017

“They show up when they say they will, and they always let us know when they're on the way. And they're extremely reliable. They've done several jobs here. I don't remember what the most recent was. I've had them for plumbing and HVAC. I'd rate them as an A overall.”

Review by

“I like the service they provide. I find plumbers to be exorbitantly priced but they're on the better side of exorbitant, I guess. They did simple drain work and stuff like that. They also installed a toilet. I'd give them a B overall.”

Review by
06/14/2017

“They were professional, courteous, on time, did what they said they were going to do and cleaned up. I thought they were thorough and well run. I had a pretty major leak under the slab that they had to mitigate. Given the situation, I'd give them an A+. First time I ever used them, and they came through in a pretty bad situation really well.”

Review by
06/14/2017

“On the whole, it was positive, but it was very costly because of the time of day. It was after five or six o'clock in the evening, so I had to pay a large price, but they were very nice. They did a leak underneath the kitchen faucet. The young man that was doing the work was very positive. He had a good personality. He was very helpful. I'd give them a B.”

“I believe they did some work for me earlier in the year. They always come within the window that they tell me. They're quick to call me back whenever I called to try to schedule an appointment. They had very good customer service. They did quality work as well. Abacus gets an A+ overall. The customer service, cleanliness, and punctuality was the best part. I have recommended them.”

Review by
06/13/2017

“They did a pretty good job. I have no issues with them. I think they were pretty expediting. We called them and they showed up the next day, which is very nice. They were able to send their plumbing guy out within a day or two. So it's just a pretty expedited and smooth process. There was a pipe leak inside the home. I think it was a sewage water pipe that the previous owner had nailed into with a nail. When we took out the nail, it started leaking. I would say they get an A overall.”

Review by
06/13/2017

“That was a long time ago. They're persistent. They gave me the quote. The job took a lot longer than they thought because the whole system, the whole waterway was backed up. They persisted and got it all fixed in several hours and they did a really good job. It was on my kitchen sink. They deserve an A. They did a good job. They were pleasant, which is always excellent. They just kept at it and they got it done; it was really backed up. They're still working hard. I would recommend them.”

Review by
06/13/2017

“It was in our bathroom. You know, I wasn't at home but my husband was at home, and they did contact me and they asked me about the work and it was OK. They changed some of our shower handles. I would say mediocre because one of the handles is loose already. I'd give them a C overall. I don't know what expertise they had, to be honest with you. But I understand there was a second person; he was being trained. Customer service with them was good. I had to remind the gentleman I was supposed to get a discount on the first-time service because we were going to be billed for it. It's extremely expensive.”

Review by
06/13/2017

“They came out and checked everything and it was just a general inspection, but I think it was free of charge with the service agreement that I had with Abacus. I want to say they did fine. There was something not draining real well, but it was super expensive to fix it with Abacus, so I actually got bids from other plumbers and I did have it repaired, but they did identify where the issue was. My other issue I wasn't real excited about, they had to come out three times to figure out they had to jet the clean out line from the outside, and they removed a toilet and put a crack in the tile. A very small hairline crack in the back. They didn't say anything to me about it. I saw it later. And they also cut into the Sheetrock behind my brand new pedestal sink and I still haven't had it repaired. They had to cut a big hole out of the Sheetrock for something they didn't really need. So it took them three times and they finally got the guy out the third time to jet it out and that's when I signed up for the service agreement. They ended up doing a couple of things that they didn't need to do. So, happy and not happy. I'd probably give them a C. Well, I mean, the third guy was great. The first two guys were not. When the right guy came out who knew what was going on, it was great. But I didn't like the first two guys, they did things that they didn't need to do. And the inspection was good. That was the last thing in December, I think. The inspection was, you know, it was an inspection. Their customer service, punctuality and cleanliness was good. That was all very good.”

“The piping upstairs and downstairs didn't run very well for a long time, and they worked a long time on that, so they were very good. They were putting new piping up in the attic. We had the old galvanized piping. They put plastic. I'd give them a B+.”

Review by

“I like the quality service and they're good people. I've had them do some plumbing work in my home and electrical work in my office. I'd give them an A+. I have already recommended them.

Review by

“They were attentive to my needs, what I needed, and they talked to me about what was going on, what had happened, and just did what I needed, and didn't try to talk me into extra stuff. My house was struck by lightning so they helped with my air conditioner. I lost my garbage disposal and they replaced that. I had to get a board for my electrical box because it was damaged. It was my first time using the company. I had three or four technicians. I had three different experiences. I'd give them between an A and A+ on all three. They did air conditioning, plumbing, and electrical work. I had to buy appliances to replace the appliances that got hurt, which they did not do. I realized I needed one, I called them out, they replaced it, and then were gone. It wasn't a big ordeal.”

Review by
12/12/2016

“They respond to my calls and they come promptly and the men seem very knowledgeable. They came twice and the last time they put in a new faucet. They also replaced a fan on my patio and they also replaced all of the ceiling lights in my kitchen. They deserve an A+. I had no issues. If anybody asked me I'd recommend them.”

“Reported problem to Abacus was to locate an apparent leak. Plumber found that we could not shut off water to the house to determine where leak was. Charged over $7 to replace the shutoff valve. Cut hole in sheetrock wall to move valve to a higher position, but realized the water line did not go in that direction. Did not repair damage to wall.”

“Abacus came out to unstop a bathroom drain. While here, they discovered the need to replace some pipes in the yard. They sent half a dozen workers, but they mostly stood around. After hours of people coming and going, they gave us an estimate of over $27,. to repair. They charged $7,. for the work they already did, which did not fix the problem. We felt pressured to have them do the work, but we put them off and got another estimate for the same work, and that estimate was for about $8,. for a total job. They said the work Abacus had already done was worth a few hundred dollars, not thousands. Needless to say, the other company did the work for us. To Abacus's credit, I emailed the owner and explained everything that had happened and how unhappy we were with their service team that we felt were overcharging us based on ‘normal, standard’ prices. We were given a refund, but we had to spend hours talking to their people, which was a huge waste of our time.”

“They were called to solve a water hammering problem in our pipes. Did not solve the problem while here I asked them to replace toilet valves. Instead of replacing the entire valve including the flapper only the upper valve was replaced. The charge in my opinion was excessive for the work done. Not a happy customer!”

“I requested service to have 2 American Standard, chair height, toilets repaired for tank leaks. The plumber showed up without the proper parts. He then went to Home Depot to purchase parts and was gone for two hours. When I called for service I gave the brand of toilet to the customer service lady and described the problem. She talked me into purchasing their ‘program’ for $5. which I thought was going to apply to this service call. It did not, so I wound up spending in excess of $3 to repair two toilets for a leaky tank and it took over 4 hours to get the job complete. I could have replaced the toilets with new ones for that price.”

“Abacus failed to arrive on time, did not deliver promised service, overcharged for service provided, and failed to actually repair my water heater. My water heater would not keep the burner lit. I called Abacus. They called after their scheduled arrival time to reschedule for the next day. The following day they arrived and inspected my water heater, said there was nothing wrong and relit the pilot light. They charged $16 dollars for the service and quoted me for install of a new water heater as mine is nearing the end of its expected life. The pilot light went out sometime that evening or the next morning. When I called to have them back to check it again, they wanted an additional service fee just to send the techs out, and would not credit what I had already paid toward whatever the problem might actually be. I called another plumber who vacuumed the vents and repaired the thermocouple for less than Abacus charged me to light the pilot light. Water heater has worked with no problems for nearly six months since. When I explained my discontent to the service manager at Abacus, I was told he would ‘see what he could do.’ This turned out to mean he would make me someone else's problem as he moved to a different position, and it took me three weeks to get a response from someone else. The best Abacus could do was give me a year of their membership plan for free. I've received no follow up, no member information, and none of the discount coupons they promised since.”
