Licensed & insured in NY ยท 24/7 dispatch
Halo Water Proofing is a NY-licensed Emergency Waterproofing company that treats every Roslyn job like it's the only one on the schedule.
Every Roslyn 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 Roslyn 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 Roslyn homeowners.
Odor is often the very first clue Roslyn homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
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.
This is one sign we tell Roslyn customers never to wait on โ wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Roslyn crews handle most.
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 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 Roslyn properties need both systems working together โ we'll say so honestly instead of selling just one.
Talk Drainage Options โMusty smell upstairs with no obvious source? Check the crawl space first โ it's usually the culprit.
Get a Crawl Space Quote โCommercial water intrusion means bigger stakes โ inventory, tenants, downtime. We scope commercial Roslyn jobs with written specs and a real timeline.
Request a Commercial Quote โHere's exactly what Roslyn customers can expect from first call to final walkthrough.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
A Roslyn 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 โ no change orders once the crew shows up.
You get documentation of the work plus a real warranty โ not just a handshake.
We've heard every Roslyn horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
Our crews stage locally near Roslyn, which is why most emergency calls get a technician on-site in under two hours.
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 โ that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Our trucks are recognizable around Roslyn โ we don't cut corners on jobs our neighbors will see.

"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
