From a hairline crack to a fully soaked crawl space, our Greenwich crew has seen it and fixed it. No guesswork, no scare tactics โ just a clear plan and a fair price.
Background-checked Greenwich technicians ยท Real warranties

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.
Every Greenwich technician we send is background-checked and trained on the exact equipment we install โ not a subcontractor picked up for the day.
We've worked on foundations from decades-old Greenwich homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment โ not a vague callback promise.
๐ +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Greenwich homeowners.
Odor is often the very first clue Greenwich homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Greenwich crews see.
Efflorescence is a reliable early sign that water is moving through your Greenwich foundation wall right now.
A Greenwich sump pump that never rests is usually undersized or nearing the end of its life.
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 hydraulic cement 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 โSome Greenwich properties need both systems working together โ we'll say so honestly instead of selling just one.
Talk Drainage Options โA damp Greenwich crawl space drives up humidity throughout the house โ we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote โCommercial water intrusion means bigger stakes โ inventory, tenants, downtime. We scope commercial Greenwich jobs with written specs and a real timeline.
Request a Commercial Quote โNo pressure, no scripts โ just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
A Greenwich technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
No verbal number that quietly grows once the truck pulls up โ the written quote is the final word.
You get documentation of the work plus a real warranty โ not just a handshake.
We've heard every Greenwich horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts โ what you approve is what you're billed.
Our crews stage locally near Greenwich, which is why most emergency calls get a technician on-site in under two hours.
Our major repairs come with written, transferable warranties โ useful if you sell the Greenwich property later.
Our technicians are trained to diagnose accurately, not to upsell โ that changes the advice you actually get.
We can supply the documentation most carriers ask for before approving a Greenwich claim.
Every Greenwich job reflects on the next referral, so we treat each one like it matters.

"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."

"French drain install took two days exactly as quoted, and the yard looked better than before."
