How We Get The Job Done
When you need basement waterproofing or flood protection in Rockville Centre, we use proven systems that work from the inside out. Whether it’s preventing leaks, managing storm runoff, or sealing the foundation itself – we go straight to the source to keep your basement protected, dry, and strong.
French Drain Installation
French drains redirect water away from your home’s foundation. They’re a front-line defense against water buildup and long-term flooding issues.
Sump Pump System
A sump pump installation activates when water starts collecting and sends it out before it has a chance to do damage. It’s one of the best defenses during storms and downpours.
Basement Crack Repairs in Rockville Centre
We seal cracks and reinforce your foundation – inside and out – so that your basement stays protected against leaks, mold, and future costly repairs.
Grated Channel Drainage
These draining systems gather surface water before it ever reaches your home’s foundation. Great for high rainfall areas, they help avoid pooling and basement seepage.
Exterior Membrane Foundation
We install waterproof membranes around the exterior of your foundation to block moisture from entering your basement. It’s heavy-duty defense that works even during the worst storms.
Foundation Grading
We expertly reshape the ground around your home to slope water away, reducing the risk of flooding and long-term water damage.
Window Well Drainage
This keeps rainwater from collecting around basement windows. Instead, it’s guided away, helping prevent leaks and dampness inside your home.
