Matt, Stacy, Jordan and Alex....Great job on the basement waterproofing! Now we wait for rain to go where it's supposed to. Before and after photos included.David and Wendy Less

The best of the best! Got a very reasonable quote from Matt within a day of calling him, and then when we needed the work to be scheduled his team came in promptly and worked so efficiently they were done in just a couple days. 10/10 recommend! Less

Matt and his team are the best in the Baltimore metro area! They came out asap and addressed the area of concern in my basement. They were honest and told me exactly what was going on and how to fix it. He didn’t make up work like some other companies do. A++++++ in honesty, communication, promptness, and overall customer care. If you have issues you must call them! Less

I want to say thank you to Matt at this company. He came to our house , told us we didn’t need anything dug up and told us how to fix the small problems he found . We had 3 other companies , I won’t name them, come out to our house and tried to force us to get work done - asking us to sign mere hours after giving us a quote . This company didn’t do that and I highly suggest you get them to come to your house if you have issues- it was the most honest and ethical business transaction I’ve been a part of in years . Trust them ! Less

This review is long overdue! If we could give 10 stars we would; To the owner and staff thank you so much you guys came in and did a wonderful job! 3 months after our basement was completed, Matt followed up with my husband regarding our well to see if it was filled with in 2 days Matt had one of his crewmen (Kevin) come in and finish the area where our well was and tied it into the current system he had placed! Kevin was very professional and always showed up on time, he showed up wasted no time he came up with a plan placing a new pit system and new sump pump! Kevin was so precise he walked around the basement and filled crack sand seams in our walls without us asking and all done at no extra charge! We recommend anyone looking to get there basement done contact Thompson and Sons water proofing! Less

They guys were very professional! At the beginning, they apologized for the noise that was about to occur. It was very noisy for a while, but they got the sump pit and pump repaired quickly! Less

Very professional and kind crew. Mike was able to have our basement done within 3 days! And it looks great, he communicated with us well with any problems that came up, but also respectful about nap time for my toddler! 🫶🏻 Matt (the owner) has been very helpful through this whole process, with this being our first house, that is also 105 years old 🫣 We've had WAY too many questions, that he's been totally awesome with helping us with!
