Halo Water Proofing has been the trusted call for Sump Pump Installation across Greenwich because we answer the phone, show up when we say, and stand behind the work.
Free, no-obligation estimates · Real warranties
Halo Water Proofing started small in the Greenwich area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
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.
📞 +1-866-476-1348Water 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.
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.
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 — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Greenwich basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.
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 →Already 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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
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 →Here's exactly what Greenwich customers can expect from first call to final walkthrough.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
No jargon, no pressure — just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
You get documentation of the work plus a real warranty — 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.
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.
Filing a claim can be confusing — we've walked Greenwich customers through this process many times.
Every Greenwich job reflects on the next referral, so we treat each one like it matters.
"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."
"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."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Greenwich contract we sign.
