Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Greenwich property, gives you a straight answer, and fixes it right the first time.
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.
Our Greenwich crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
Talk to a real Greenwich technician today, not an automated queue. We'll explain what's going on and get you scheduled.
๐ +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Greenwich crews hear about most.
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.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
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.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
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 โNot every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair โMost Greenwich pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check โFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
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 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.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure โ just a clear look at what's actually going on.
Every Greenwich quote is written before work starts, not estimated verbally and adjusted later.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
Plenty of companies advertise Interior Drainage System in Greenwich โ here's what actually separates the ones worth calling from the ones that aren't.
There's no verbal quote that grows once the crew shows up โ the written estimate is final.
Our crews stage locally near Greenwich, which is why most emergency calls get a technician on-site in under two hours.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
We'd rather earn a repeat Greenwich customer with an honest fix than push a system you don't need.
We can supply the documentation most carriers ask for before approving a Greenwich claim.
Word of mouth is still how most Greenwich customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything โ basement's been dry since."
"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."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Greenwich work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
