Halo Water Proofing is a NY-licensed Sump Pump Installation 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.

📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Hewlett homeowners.
Odor is often the very first clue Hewlett homeowners notice, well before any water is visible.
Small cracks in a Hewlett 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 Hewlett sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Hewlett schedule.
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.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →We seal active Hewlett foundation cracks with epoxy 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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
