The tenant complained of water intrusion in the basement. We found mold, high humidity, and water intrusion; but only on one side of the basement.

We first installed our patented WaterGuard system to provide drainage and keep the basement dry. We then thoroughly cleaned up the mold with CleanStart Plus, which destroys mold completely.

Our TripleSafe pump was installed to remove any water that might accumulate, and to keep the basement continually dry. The TripleSafe contains an additional battery operated pump, which kicks in during power outages, so water NEVER accumulates.  

Finally, we installed our SaniDry Sedona dehumidifier, which the client never needs to empty, to prevent the mold from coming back.

Dry basement, mold removed, and basement humidity permanently under control.  Happy Tenant, Happy Landlord!

Job Stories From Port Jefferson, NY
Port Jefferson, NY Basement Waterproofing

This homeowner in Port Jefferson, NY had a leaking basement which was making part of the basement unusable and the homeowner wanted to get this issue resolved and gave us a call. Our team was able to make this homeowner's basement completely dry and usable by installing our basement waterproofing system in this basement, our basement waterproofing system consists of our Waterguard and sump pump system. Our system is designed so that as water tries to enter your basement our WaterGuard system will catch the water before it can enter your living space and directs it into our sump pump system which then discharges the water back outside leaving this basement completely dry and usable. Our team also came in and installed our dehumidifier in this basement which is also a self-discharging system meaning you never need to worry about emptying the water bin. Our dehumidifier isn't just self-discharging but it also filters out any moisture or small mold particles that might be in the air.

Project Location: Port Jefferson, NY
I have some cracks in my cinder block basement wall at ground surface level and do not know whether to worry or not. The crack runs mostly horizontal without bowing of the wall but in one spot there is a diagonal crack near a window. I need to have someone who specializes in this so that I paper work when I try to sell my house.
Project Location: Port Jefferson, NY
I currently rent out my house and the tenant advised that water is getting into the basement. My handyman can't confirm what the true issue is (checked gutters, no puddling outside when it rains, etc.). He believes there is a grading issue, but thinks there might be more to it and I should get someone that specializes in the industry. The house was built in 1920 and it appears there was some patchwork in the basement by the previous owners. There are two entry points where the water is getting in - front/back left side of the house (when facing the house).

Stress Crack in Basement. Foundation Wall
Project Location: Port Jefferson, NY
We have some structural damage to our house. The Sun Room has settled or sunk down approximately 3-4 inches. This has caused a large crack in the wall between the main part of our home and the sun room. In addition we notice a bowing of the exterior wall. I would assume this was caused by the stress of the Sunroom. We also noticed cracks in the basement walls.
