Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Hewlett property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in NY · Real warranties
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 Hewlett crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our Hewlett crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
Talk to a real Hewlett technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Hewlett crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Hewlett crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Hewlett 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.
Peeling paint near the floor upstairs is one of the last signs Hewlett homeowners connect to a basement problem.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Hewlett crews handle most.
A flooded Hewlett 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 →We seal active Hewlett foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Hewlett pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Hewlett basement floor at all.
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 Hewlett 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 Hewlett property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
Every Hewlett 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.
We've heard every Hewlett 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.
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.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We can supply the documentation most carriers ask for before approving a Hewlett claim.
Word of mouth is still how most Hewlett 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."
"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."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"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."
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 Hewlett contract we sign.
