He has all his ducks in a row in regards to insurance, licensing, bonds, etc. He is honest and does everything by the book. I got him connected with NW and they have told me their customers are very happy with his service, I'm sure you will be too." Dave Kuca at A+ Backflow responded promptly to my call and was able to fit me in with short notice so I could meet the city's deadline. He did a great job and accepts credit cards with a Square reader.

I contacted several repair companies. Because of bad experiences in the past, I was very careful. For example, one company told me--after I signed the contract-- that the leak was in a difficult location and asked for more money to dig in a different spot. That made me feel confused and even more stressed. This time, I hired David from All City Sewer Repair to replace the whole water line. Compared to the other companies, David took care of everything from start to finish--with no stress for me. He made the whole process easy and smooth. He is very thoughtful, reliable, and his price was fair and honest. Most of all, I was happy with his strong sense of responsibility. Even the cleanup (after the job was perfect. Meeting him was really good luck. He did a great job and has a great personality If you're dealing with a leaking pipe, just call David. I promise, you won't regret it.

I had services from…read moreCode Mechanical for annual maintenance on my old system and I was so impressed that I decided to have them do an estimate on my replacement system. Well, after several estimates from different companies Code Mechanical was the best overall. $1k to $5k below the other companies for the same or similar equipment. A few of the other estimates included service contracts and additional add Ons that I did not ask for. Normally that's okay to offer but not as part of the main estimate (should have been presented apart from the main system estimate). I felt they were trying to get me to accept an estimate with add Ons and services I did not ask for. Felt dishonest and aggressive. Scheduling the install was easy the entire process was great. Code Mechanical also did all of the work to submit my rebate to my local power company, and it was submitted on the same day the unit install was completed and I was provided the tracking number for the rebate status. I also had interaction via email and phone with the main office staff, and everyone offered to provide any assistance or information I needed. This is true customer service when you contact a company, and its management reaches out to you and offers assistance and support for your project. They cover a large area and considering they are about 40 minutes away from my home I was able to contract them for my project. Meaning they beat all of the local companies estimates which is impressive considering they have to travel so far to provide the services. Highly recommended. Estimates are free and so it's worth the time to get a few - just make sure to include Code Mechanical as in my opinion they were the best of "five estimates". I had estimates for over one week and after reviewing all of them and checking on the companies, only Code Mechanical rose to the top. To be honest I felt the other companies were giving large estimates due to the federal and local rebates and so it appeared they wanted to charge more because the rebates made the cost look better. My estimate from Code Mechanical did not reflect "outside rebates" in the estimate cost section. They just noted that the system qualified for these rebates on the bottom of the estimate so I would know. That's what I call being honest about the true cost of the system replacement. I provided a lot of information in this review as I did my research and took the time to have several companies provide estimates and so it's all about the entire process of hiring a contractor and finding the best one for your needs. Code Mechanical is the best.

It was a very simple job just installing the tub and the tub and shower valve. First they somehow neglected to connect the drain when they put in the tub. This obviously caused a leak when I first used the tub and damaged the closet ceiling and walls below. They installed the valve handle improperly so it was sticking way out from the wall and tried to tell me that it was within manufacturers tolerance. I looked it up it was not within tolerance. They finally came back and corrected that but then they billed my contractor for coming back to correct their previous mistake. They initially agreed to pay my contractor to fix the closet damage but then ended up just swapping out their final billing, which included the overcharge, so my guy was shorted and Adept got off too easy on the damage repair.
