Halo Water Proofing has been the trusted call for Exterior Waterproofing across Greenwich because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in OH · 24/7 dispatch
Halo Water Proofing is a OH-licensed Exterior Waterproofing company that treats every Greenwich job like it's the only one on the schedule.
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.
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 — not a vague callback promise.
📞 +1-866-476-1348Most Greenwich calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Greenwich basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Greenwich crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Greenwich schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Greenwich basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in Greenwich tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Greenwich after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Greenwich basement floor at all.
Talk Drainage Options →A damp Greenwich crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We handle below-grade waterproofing for Greenwich property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your Greenwich property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Greenwich quote is written before work starts, not estimated verbally and adjusted later.
You get documentation of the work plus a real warranty — not just a handshake.
Plenty of companies advertise Exterior Waterproofing in Greenwich — 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 — the written estimate is final.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
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 — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."

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.
