Waterproofing Services for Windham County Homes

Our systems are designed for Connecticut’s northeast corner, where rural soil, sloped lots, and aging homes can create unique water pressure and drainage issues.

Full Interior & Exterior Waterproofing

Protection Where You Need It Most We build complete systems that stop water at every point of entry: walls, floors, corners, and seams. Whether it’s from inside or out, our waterproofing solutions are custom-fitted to your foundation and the land it sits on.

Sump Pump Installation & Repair

Prepared for Every Storm Proper sump pump installation is key in Windham homes, especially near the Quinebaug River or in flood-prone valleys. We install top-tier pumps, fix failing systems, and offer battery backups for power outages.

Foundation Crack Repair & Tie Rod Hole Sealing

Stop Small Leaks Before They Become Big Problems Cracks and tie rod holes make it easier for water to follow the route of least resistance. We carefully seal all openings with professional-grade material to permanently reinforce your foundation and block moisture.

Mold Remediation & Moisture Control

Healthy Basements Start with Dry Walls Mold poses a health danger in addition to being an annoyance. We identify the root cause, safely remove affected areas, and apply waterproof coatings to make sure it doesn’t return.

French Drain System Installation

Redirect Water, Protect Your Home If your home is on a slope or the soil can’t drain properly, a French drain system may be the perfect solution. We excavate and install deep drainage paths that divert water away from your foundation and relieve pressure from below.

Basement & Garage Epoxy Floor Coatings

Stronger, Cleaner, Moisture-Resistant Floors We repair, level, and coat your concrete surfaces with heavy-duty epoxy finishes that look clean and resist moisture, spills, and wear, ideal for unfinished basements, workshops, or garages.
