This was so unlike any experience I have ever had with contractors. Your company made me feel good throughout the process, from initial estimate to project completion. I am also impressed with the quality and design of your systems. I await the first heavy rain to confirm that the repairs have solved my basement water problems, but given my experience so far, I am confident that I will be satisfied.

Thank you.

We have had our system for 6 years and had no water problems even during Sandy and Irene. Previously, water was a continual problem. Our previously wet basement has become a wonderful family gathering and storage area.

Am convinced that my basement water issues are now behind me.

John H. John H. Whitestone, NY

When Ken from Quality 1st Basement Systems came to the job, he impressed me with what he knew, so I thought I would give him a shot at it. We are actually in construction ourselves, and we were going to do the job ourselves too, as we're normally not impressed with other contractors. Besides, we had a lot of work to do in the house already, so we just got it ready for them to do it instead. When they came, he and his workers were excellent. They worked really fast, and did a good job, as well or better than I expected, and I don't say that about many people.

I've had work crews come over and make a mess that I spent days (weeks) cleaning up. Quality 1st Basement Systems wasn't like that at all. They showed up on time, did a great job in the timeframe they had originally promised and left my basement clean and usable. They hauled away the trash as well. So far so good! I'm very pleased with the results.

Hollis's Basement & Foundation Contractor

It has been 25 years now that we have been Hollis's trusted basement & foundation contractor. From basement leak repair, to concrete lifting to basement drain installation your neighbors chose us and for good reason.

We have 25 patented basement products, are dedicated to quality and provide permanent basement solutions.

Basement Waterproofing & Crawl Space Repair

If you have experienced basement flooding or leaking cracks we fix the issue. We seal and repair any wall cracks and install a basement drain. The interior drainage system collects any water sneaking into your home and drains it to an efficient sump pump. From there the water is pumped out and away from your home before you ever notice.

The same applies with leaking or wet crawl spaces. Along with the drainage systems in the basement or crawl space we also install energy-efficient dehumidifiers to control the relative humidity. By controlling the space mold and rot are prevented.

We Provide:

Basement Waterproofing
Crawl Space Encapsulation
Exclusive, Patented Products
Humidity Control

You Receive:

Permanently Dry Basement
Clean Protected Crawlspace
Protection against Mold
Improved Home Value
