Basement Waterproofing in Greenwich, CT
Stop Water Before It Becomes a Bigger Problem
Water in your basement does not wait for a convenient time to show up. If you have noticed damp corners after a storm, a musty smell that keeps coming back, or water moving across the floor, you already know how fast a small problem can turn into a bigger one.
United Waterproofing provides basement waterproofing in Greenwich, CT homeowners can count on for real results. From urgent leak repair to long-term foundation waterproofing, we use interior drainage, exterior protection, sump pump systems, and drainage improvements to keep your basement dry and protected.
Why So Many Greenwich Basements Take On Water
Greenwich homes face a mix of heavy rain, changing soil conditions, and aging foundation systems. That combination puts constant pressure on basement walls and floors. Once water finds a weak spot, it keeps coming back until the source is fixed.
Most basement water problems in Greenwich come down to one or more of these issues:
- Grading that slopes toward the house instead of away from it
- Gutters and downspouts that dump water too close to the foundation
- Hydrostatic pressure pushing groundwater against basement walls after storms
- Hairline cracks in concrete or block foundations that slowly widen
- Drainage systems that were never built to handle today’s rainfall
None of these problems fixes itself. A small leak can turn into a much larger basement repair Greenwich project if it is ignored. By the time that happens, homeowners are often dealing with mold, warped flooring, damaged finishes, or foundation movement that could have been avoided.
How We Waterproof Your Basement
Every basement leaks for a different reason. That is why we do not use a one-size-fits-all fix. As a trusted waterproofing contractor in Greenwich, we start with a careful inspection to find out exactly where the water is coming from, then build a system around that problem.
Depending on what we find, your waterproofing plan may include:
Interior drainage and sump pumps
An interior drainage system collects water before it reaches your floor and moves it safely to a sump pump. This is often a smart choice if you want to protect a finished basement or avoid major excavation outside.
Exterior membranes and French drains
This is what many homeowners think of as foundation waterproofing. A barrier and drainage system are installed around the foundation wall to keep water from reaching the basement in the first place.
Basement crack repair
Small cracks can become active leak points fast. We seal and repair them to help stop water from entering through the foundation.
Sump pump installation with battery backup
A sump pump gives your basement a way to handle heavy water flow during storms. Battery backup helps keep the system running even when the power goes out.
Stormwater management
Sometimes the real issue is outside the home. We can improve grading and drainage so rainwater moves away from the foundation instead of pooling around it.

Got Questions? We've Got Answers.
If you see standing water after storms, damp walls, a musty smell, white chalky residue on concrete, or cracks that seem to be growing, it is time for an inspection. Catching the problem early usually means a smaller and less costly repair.
We inspect your basement, find out how water is getting in, and design a system to stop it. That may include interior drainage, exterior waterproofing, sump pump installation, crack repair, or drainage work around the home.
Interior waterproofing manages water after it enters the basement by collecting it in a drainage system and moving it to a sump pump. Exterior waterproofing stops water before it reaches the foundation wall. Many homes need a mix of both, which is why we inspect first.
The cost depends on the size of the basement, the way water is getting in, and whether the repair needs interior work, exterior work, or both. After a free inspection, we provide a clear estimate so you know the full cost before work begins.
Most interior projects take about 2 to 5 days. Exterior projects usually take 3 to 5 days, depending on the scope. We keep the job organized, protect your home, and work to keep disruption as low as possible.
