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 · Written pricing
Halo Water Proofing is a NY-licensed Interior Drainage System company that treats every Hewlett job like it's the only one on the schedule.
We don't run a bidding war between crews. The Hewlett technician who inspects your property is the same one who does the repair, start to finish.
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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Hewlett homeowners.
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.
Efflorescence is a reliable early sign that water is moving through your Hewlett foundation wall right now.
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 Hewlett basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Hewlett emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not 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 →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 →Some Hewlett properties need both systems working together — we'll say so honestly instead of selling just one.

A real technician asks the right questions to understand what's likely happening at your Hewlett property before anyone drives out.

The number you approve is the number you're billed — no change orders once the crew shows up.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.

If your Hewlett 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 Hewlett customers through this process many times.
Every Hewlett 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."
"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."
"Straightforward commercial quote, professional crew, no back and forth."
"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."

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.
