Licensed & insured in NJ · 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.
Every Lawrenceville 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 Lawrenceville 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Lawrenceville calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
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 Lawrenceville schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Lawrenceville crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in Lawrenceville tends to widen existing cracks over time, so sealing early usually costs less than waiting.
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 Lawrenceville properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Lawrenceville crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We handle below-grade waterproofing for Lawrenceville property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
A real technician asks the right questions to understand what's likely happening at your Lawrenceville property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
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.
We've heard every Lawrenceville horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
We'd rather earn a repeat Lawrenceville customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Lawrenceville customers through this process many times.
Every Lawrenceville 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."
"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."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Lawrenceville work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
