Licensed & insured in NY · Written pricing
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.
We don't run a bidding war between crews. The Malverne technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Malverne 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 Malverne 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 Malverne homeowners.
Odor is often the very first clue Malverne homeowners notice, well before any water is visible.
Small cracks in a Malverne foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A Malverne sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Malverne customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Malverne property, chances are we've already fixed something similar nearby this month.
A flooded Malverne basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.

You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
No jargon, no pressure — just a clear look at what's actually going on.
Every Malverne quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
Plenty of companies advertise Vapor Barrier Installation in Malverne — 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.
Our major repairs come with written, transferable warranties — useful if you sell the Malverne property later.
If your Malverne basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
Filing a claim can be confusing — we've walked Malverne customers through this process many times.
Every Malverne job reflects on the next referral, so we treat each one like it matters.
"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."
"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."
"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 Malverne contract we sign.
