This homeowner had finished his basement but due to foundation cracks and seepage through the foundation, he would get water in his basement whenever it rained or snowed. Using our patented WaterGuard® drainage system and our SuperSump® premier pump, we got this wet basement back to a dry and comfortable living space, allowing the customer to fully enjoy his home.

Job Stories From Brentwood, NY
Basement Waterproofing Contractor in Brentwood, NY

A homeowner in Brentwood, New York had a basement that was constantly flooding causing the homeowner to only use parts of their basement. The homeowner was tired of living with a flooded basement and decided to reach out to us, after sending one of our specialists to inspect their basement issue they recommended that they waterproof their basement using our basement waterproofing system. Our basement waterproofing system consists of our waterguard system, our sump pump system, and our self-discharging basement dehumidifier which all work together to keep your basement dry, usable, and healthy. The way our system works is by our crew coming in and jackhammering out a trench around your basement perimeter and installing our waterguard system in the trench and connecting it to our sump pump system. This works to keep your basement dry by capturing any water before it can enter your basement and directs it into our sump pump system, which then removes the water from the basement and away from the foundation of the home. To ensure the basement remains completely dry and healthy we installed our basement dehumidifier that removes moisture, mold, and mildew particles from the air helping to improve the overall air quality in this space. Now this homeowner has a basement that will remain completely dry and usable for many years to come. 

Brentwood Crawl Space Encapsulation

This homeowner in Brentwood had a crawl space that was nasty and unusable so they gave us a call to see how we could take their nasty crawl space and transform it into a usable crawl space. Our team here at Healthy Basement Systems was able to turn this homeowners crawl space into a usable space by encapsulting the crawl space with our CleanSpace vapor barrier that will make the area clean, dry, and usable. Now the homeowner can store things in their clean crawl space. 

Waterproofing and Mold Removal in Brentwood, NY

A homeowner in Brentwood found that his basement had dangerous mold and humidity issues that were harmful to his health. The insulation in the basement was full of moisture due to high humidity levels, which created the perfect conditions for mold growth. Because of the mold, the homeowner was breathing in unhealthy air. He called Healthy Basement Systems for a solution - and our dedicated team worked hard to solve the problems!


Our team first removed the old insulation from the home's basement, and then sprayed Cleanstart Sanitizer along the walls and ceiling for mold remediation. Next, they installed our CleanSpace Vapor Barrier system, which made the basement insulated and clean, and gave the whole room a fresh glow. The vapor barrier system also keeps out moisture and allowed this basement to become waterproofed. Our Sanidry dehumidifier was placed inside the basement to control and regulate the air temperature and prevent the basement from ever becoming humid in the future. 


Now that his basement is transformed, the homeowner can enjoy his summer without worrying about the threats of mold and humidity! Healthy Basement Systems turned his dirty basement into a clean, waterproofed mold-free, insulated space with healthy air!

We have a cracked foundation, the front of the house seems to be shifting. We also have very dirty musty crawl spaces. The original house is about 100 years old, and the previous owners did numerous extensions. I wanted to see if there was a way to fix and repair the foundation, as well as do something about the crawl spaces.
