Basement Waterproofing, Basement Finishing, & Crawl Space Repairs in Brookhaven, Islip, Oyster Bay, LI

Healthy Basement Systems is more than a basement waterproofing contractor. We specialize in "All Things Basementy," including basement and crawl space waterproofing, basement remodeling, and foundation repairs. We have the experience, training, and tools to turn a wet basement or dirt crawl space into a dry, healthy environment. We also provide permanent structural repairs for foundation settlement and cracking.

Some problems are obvious, like water in the basement, foundation cracks, or musty odors coming from the crawl space - but there may be more going on under your home than you realize. Or you might be interested in extending the living space in your home and transforming the basement into an apartment, an entertainment area, or a mancave.

Healthy Basement Systems provides solutions for these problems and more! We can thoroughly inspect your basement, crawl space, or foundation and provide a Free Estimate for quality, affordable services that meet your home's needs. Schedule yours in Oyster Bay, Huntington, Smithtown, and nearby today.
