Basement Waterproofing

The experience was wonderful. The job was done to all specifications, the clean up was spotless. I would highly recommend Keystone Basement System for all your basement repairs.

Very clean and professional done

These guys hit a home run from start to finish, From the free inspection to quick and tidy work they really solved my problems and the value was exceptional.

Excellent Company

Without hesitation, I would highly recommend Keystone. The company rep, Jeff Martello, was very professional, courteous and addressed all of our questions and concerns regarding the problem in our integral garage. The repair crew of Josh and Brandon were great. When they were done with the job, everything was cleaned up perfectly. You will not go wrong by this company.

I had carbon fiber straps for bowing walls

I am very pleased with the work from Keystone. Brian was so good explaining everything to me for I am a woman He took the time and answered all my questions. The crew Charles and Eric was wonderful too. They also was explaining to me what they were doing so I would understand. They cleaned everything up and you wouldn't know they were even here. So a BIG thank you to the 3 men and Keystone. I will highly recommend you

Excellent work

We would like to commend the staff of Keystone Basement systems for the excellent work they did for us this month. Especially we want to commend the crew led by Josh and including Robert and Brandon for doing the work so diligently and exceptionally well. Austin was also helpful. The whole project was managed efficiently and graciously by Renee. We recommend this firm's services unequivocally.

Life Time Warranty!

Keystone installed our system in 2006 ~ GREAT Job!! 13 years later our sump pump failed and I called and left a message on a Sunday evening and by Monday morning at 8:30 a.m. Renee returned my call! She was patient and a great help! Tuesday afternoon, two employees were here to remove the old pump and replaced it with a NEW PUMP ~ FREE! It was a pleasure to deal with a company who is trustworthy and true to their word "Lifetime warranty". Very good experience with everyone!!!

Excellent job!

Everyone involved in our contract concerning our flooding basement problems we're excellent! With all the bad rainy weather we have had, our basement would have been flooding non stop.. the indoor French drain system with sump pump that was installed has kept it dry.. saving our backs and sanity! We are so grateful for a job well done!

Very Clean

I have to say that I did not get water in my basement after both big rains that we had. This is the first time I am not cleaning up muck in some time. I was impressed by how clean the work was also.

Quality crew!

Just wanted to write to say what a pleasure it was to work with Keystone, and also, what a relief! As a single mom, I'm always extremely wary about having people in and around my house. You just never know who's a weirdo and who will try to take advantage. With Keystone Basement Systems, everyone was competent, professional, reliable, and kind throughout the entire process. Pricing was explained thoroughly and fairly. I was treated with respect. And the end result was gorgeous! I love my finished basement, and my teenager loves it more. It's perfect! Thanks to everyone who worked so hard and did such a great job.

Professional and down to Earth

Recently this past summer with all of the rain we have experienced I started having issues with water in the basement. Nothing too bad but water here and there during hard rains. The salesperson that was sent was very professional and very thorough with his inspection. It was minor enough of a problem that they were able to nullify the situation from the inside without digging on the outside. They were finished in one day. I haven't seen any water since. These guys also finish basements which I plan on taking advantage of too.
