From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Hewlett before. We show up, we diagnose it straight, and we fix it right.
Halo Water Proofing started as a small NY crew and grew because Hewlett customers kept referring us to neighbors — that's still how most of our work comes in today.
Every technician on our Hewlett crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Hewlett customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Hewlett-area homes.
Efflorescence is a clear sign that water is actively passing through your Hewlett foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Hewlett lot's water table.
This is one sign we tell Hewlett customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Hewlett homeowners notice, even though the moisture issue started in the basement months earlier.
Every Hewlett property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Hewlett basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew immediately, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Freeze-thaw cycles in Hewlett, NY push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Hewlett lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Hewlett lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Hewlett crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Hewlett commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

Every Hewlett job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
Whether you're in the older, established parts of Hewlett or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
