Licensed & insured in NJ · Real warranties
Halo Water Proofing is a NJ-licensed Foundation Crack Repair company that treats every Greenwich job like it's the only one on the schedule.
Every Greenwich technician we send is background-checked and trained on the exact equipment we install — 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.
Talk to a real Greenwich technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Greenwich homeowners.
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.
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 — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Greenwich emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
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 →Older Greenwich homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
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.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
A Greenwich technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
The number you approve is the number you're billed — no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
Plenty of companies advertise Foundation Crack Repair in Greenwich — here's what actually separates the ones worth calling from the ones that aren't.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
If your Greenwich basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.

"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
