Free, no-obligation estimates ยท Written pricing

We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
We don't run a bidding war between crews. The Greenwich technician who inspects your property is the same one who does the repair, start to finish.
Our Greenwich crew leads carry years of hands-on repair experience, not just sales training โ which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment โ not a vague callback promise.
๐ +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Greenwich crews hear about most.
A musty smell usually means moisture is already moving through your Greenwich basement, even if the floor looks bone dry.
Small cracks in a Greenwich foundation rarely stay small โ seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Greenwich basements are the same โ soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast โ extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help โWe seal active Greenwich foundation cracks with polyurethane injection โ stopping the leak at its source instead of patching the surface.
Ask About Crack Repair โAlready have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check โAn interior drain tile system routes water to a sump pump before it reaches your Greenwich basement floor at all.
Talk Drainage Options โOlder Greenwich homes with vented crawl spaces see the biggest swings in seasonal humidity โ encapsulation closes that off for good.
Get a Crawl Space Quote โWe can phase larger Greenwich commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote โNo pressure, no scripts โ just what actually happens once you call +1-866-476-1348.
