Nasty Crawl Space in Hollis, NY

Before After
Nasty Crawl Space in Hollis, NY Nasty Crawl Space in Hollis, NY

Quality 1st Basements completely transformed this nasty and damp crawl space into a dry and healthy area underneath the home of Hollis, NY homeowner. Quality 1st encapsulated the crawl space to seal it off from the harmful outside environment. Since the homeowner's heater and pipes were located in the crawl space, the pipes would freeze and the heater would have to work extra hard to heat the home.

The crew installed SilverGlo, a heat barrier to reflect heat back into the crawl space. This will lower the cost of their heating bill and prevent their pipes from freezing! The CleanSpace liner was installed over the SilverGlo to the walls and floor to prevent water seepage and moisture in the future. The homeowner was amazed at the transformation and relieved that they no longer had to worry about water again!

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.

  • Basement Waterproofing
