Testimonials
EXCELLENT Based on 92 reviews Micheal Vakas2025-03-01Trustindex verifies that the original source of the review is Google. Seriously, one of the best companies I have had a chance to work with. I am a realtor and some times I need work done quick. These guys completely understand. They work with what you need and in those time limits. Recently I had a client that need some work in the basement in order to get an FHA Loan on a property. They came in and got it done in 3 days. It was great quality and it satisfied the loan. Had they not come in, my client would have been on the street with 3 kids. No other company had the time or willingness to help. They felt for her situation and made things happen in record time. This is the type of A player you need in business and even in your personal life. In the end they lead with commitment and action and they will be on my team for life.

John Douglas2025-02-03Trustindex verifies that the original source of the review is Google. We had a problem with mold in our basement from not using a dehumidifier. We got six different quotes to take care of the issue. Affordable Basement was very competitive with their pricing and I was very impressed with Billy’s knowledge and commitment to get rid of the problem. Michael, the owner of the company, came by to confirm the quote when we told them we were going to use them. He backed up everything Billy had presented. Billy and Ryan showed up right on time and got right to work. I felt they went out of their way to do everything they promised, and then some. I only wish I could use Affordable Basement and these two men for all my home improvement projects.

Billy and team did a great job. They worked efficiently, left everything very clean, and actively worked to minimize damage to the surrounding area walls. We are repeat customers (for different sections of basement) and would recommend. Gerasimos Michalitsianos2024-10-06Trustindex verifies that the original source of the review is Google. I have been needing to write a review of this company for a long time. In 2022, this company came and installed a sump-pump system in my basement. They also dug a trench to direct the water flow. This effectively ended the puddles of water collecting there during heavy rains. Groundwater intrusion. Problem vanished completely. At least for a couple years. Then water began collecting in the same area again this year in 2024. I had assumed that something may be wrong with the waterproofing system this company had installed. A couple technicians came out to take a look, and showed me that indeed, it was rather a plumbing issue instead (a leaking toilet, among other issues). They even showed me the video footage from the phone when flushing the toilet. They could have charged me $150 or so for the service fee to come take a look (or whatever it is they usually charge). They did not. Note even a dime. Yes I had to get some serious plumbing work done afterwards. But this was at no fault of this company, and these plumbing issues were not related to the waterproofing system, which is still running like a top. Ken and his team were truly great to deal with. Great people. If you need basement waterproofing done, going with this company is an absolute no-brainer. Nick2024-03-07Trustindex verifies that the original source of the review is Google. I've had two sump pumps installed in my finished basement by this company. On both occasions I received timely and excellent customer service from Kelly, the general manager, inspection/project managers who do the initial inspection and draft plans and estimates to the technicians that completed the jobs. It's never an easy ordeal undergoing basement issues and this company has a wonderful team of people to get you through this moment. On my most recent installation this year I do want to thank Kelly for her consistent awesome customer service over the years. I love her personality. Kenneth who did my initial inspection and got the ball rolling on the project. He was knowledgeable, kind and patient throughout that first visit and really helped to relieve some anxieties. The technicians, who completed the really tough job Billy (foreman), James, Dave, Billy and Ron. These guys are keepers!!
