Halo Water Proofing has been the trusted call for Exterior Waterproofing across Hewlett because we answer the phone, show up when we say, and stand behind the work.
Background-checked Hewlett technicians · Written pricing
Halo Water Proofing started small in the Hewlett area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Hewlett technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Hewlett 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 Hewlett 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 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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
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.
These upstairs clues usually show up months after the basement moisture problem actually started.
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 polyurethane injection — stopping the leak at its source instead of patching the surface.
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 →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 →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Hewlett jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Hewlett 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.
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.
We'd rather earn a repeat Hewlett customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Hewlett customers through this process many times.
Our trucks are recognizable around Hewlett — we don't cut corners on jobs our neighbors will see.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"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 Hewlett contract we sign.
