"We had a very complex front door to install and On the Level did a superior job -- the quality of the work was superb, the price was more than fair, and all of the work was completed in a timely manner. Peter did a great job communicating through out the process --we would hire them again."

"Workman took three days to shore up the foundation of this very old garage. He was polite, and did a nice job. Estimates from several providers were all over the map, since some recommended extensive work involving the use of helical piers, and installation of a new concrete block foundation. I went with more conservative repair.. It looks fine, and I hope I made the right decision."

"Just as our previous experience with Oscar and his team, everything went smoothly. They were careful to do the job properly while simultaneously being respectful and thoughtful. In the past we have had workmen from other companies who I was grateful to see leave. Quite the opposite with Oscar and his team!"

"I used Apex to fix a situation where water would leak into my basement through the electrical panel during a long, heavy downpour. It was a particularly unique and difficult problem to solve which involved excavating under part of a flagstone patio, determining the source(s) of the leak and sealing. Their final solution was very thorough and attacked the problem from multiple directions. I was impressed with their dedication to doing the job right. The clean-up was also thorough (the patio looked better after they left than before they started!) The crew was great! They worked hard and knew what they were doing. Since it was such a tricky problem, Lou, the manager, was on-site for most of the day. They also have an excellent electrician on the team which was a definite plus for this project. I used Apex a couple of years ago to renovate the basement and was very pleased with the result of that project as well. They’ve been in the business for many years and are deservedly proud of their reputation for quality work. I wouldn’t hesitate to use them again."

"My garage floor was coated in 2013 with a 10-year warranty, and areas have not adhered properly many times. The company sends workers to "fix" the affected areas, but the fixes do not hold up. The company re-coated the floor once, but I believe that the bare floor was not ground properly when the coating was first applied. Now my floor is unsightly with areas bare or that have been re-worked over and over and not looking like the original finish. A few weeks ago, workers came to re-work the areas, but I told them not to do so because I wanted a more permanent solution to the problems. I have had several email communications with a manager. All they seem to want to do is apply more coating to the affected areas. This pretty much makes the warranty useless."
