The customer called Healthy Basement Systems after several occasions of water flooding their basement. Water was coming in at the imperfect joint where the foundation wall met the floor. Rich Alexander did a thorough inspection of the basement, and came up with a waterproofing solution that would keep the water from flooding the basement. 

Our expert install team first installed our patented WaterGuard piping system around the full perimeter of the basement. WaterGuard ensures that water never reaches the basement floors and never gets clogged. Next, we installed the SuperSump pump system do get the water out and away from the house. Lastly, we installed CleanSpace along the soundation walls to create a vapor barrier between the cold stone walls and the basement area, lowering humidity and adding protection. 

The customer has not had any issues with water in their basement since installation, and they are happy to know that our work comes with a lifetime guarantee!

Job Stories From Greenlawn, NY
Crawl Space Repair in Greenlawn, NY

A homeowner in Greenlawn, New York had a crawl space that was constantly getting flooded with water due to living in an area with a high water table, the homeowner was worried that the constant moisture would lead to rotting wooding and mold, so they gave us a call to come inspect their crawl space. After sending one of our specialists out to inspect their crawl space they recommended they have their crawl space encapsulated if they wanted it to be a dry healthy space. The way we encapsulate a crawl space is by our crew coming in and installing a layer of drainage matting over the dirt floor, this will separate the crawl space from the dirt while still allowing water to move freely under that drainage matting. On top of the drainage matting we install our CleanSpace vapor barrier system, which will prevent any moisture from entering the crawl space while making the space a clean, dry, bright, usable space. To ensure this crawl space no longer floods with water we installed our sump pump system, which will collect and discharge any water that flows under the drainage matting and discharges it out and away from the house.  To make sure this space remains dry and healthy we installed our SaniDry dehumidifier in the crawl space, which will remove any moisture, mold, or mildew from the air helping to improve the overall quality in the space. Now this homeowner has a crawl space that will remain completely clean, dry, and usable for many years to come.

Over the past 6 - 12 months, the floors in my house (located in the Huntington, NY area) have been progressively shifting and becoming uneven in various areas/rooms. It's a 60+ old house, that I've owned for 18 months, and I'm not sure if its related to settling, moisture, or something else.
