New York County Basement & Crawl Space Contractor

A wet basement or damp crawl space can make it difficult to fully use and enjoy your home. Water intrusion, excess humidity, musty odors, and other moisture-related problems can also become worse when the source of the problem isn't properly addressed.

For 25 years, homeowners in New York County have turned to us for basement waterproofing and crawl space solutions designed to help keep below-grade spaces dry, clean, and protected.

Basement Waterproofing in New York County

Basement water problems can show up in several ways. You may notice water coming through cracks, moisture where the floor meets the wall, puddles after heavy rain, musty odors, or consistently high humidity. Instead of simply addressing the visible water, we look at how moisture is entering the basement and recommend a waterproofing solution based on the conditions in your home.

Our basement waterproofing systems can include interior drainage, sump pumps, wall crack repair, and dehumidification. An interior drainage system collects water entering around the basement perimeter and directs it to a sump pump, which pumps it safely away from the home.

Crawl Space Repair & Encapsulation

Crawl spaces are especially vulnerable to moisture because they are often exposed to damp soil, groundwater, and humid air. Over time, those conditions can contribute to musty odors, condensation, mold growth, wood rot, and an uncomfortable environment beneath your home.

Crawl space encapsulation helps separate the space from moisture in the ground and surrounding environment. Depending on your crawl space conditions, we may recommend a combination of drainage, a durable vapor barrier, sump pump protection, and dehumidification to create a cleaner, drier space.
