Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your New Hampshire property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · 24/7 dispatch
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 New Hampshire 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 New Hampshire 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.

A musty smell usually means moisture is already moving through your New Hampshire basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our New Hampshire crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A New Hampshire sump pump that never rests is usually undersized or nearing the end of its life.
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.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our New Hampshire crews handle most.
Storm season keeps our New Hampshire 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 →A failed sump pump is the top reason for emergency calls across New Hampshire after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp New Hampshire 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 can phase larger New Hampshire commercial projects around business hours or tenant schedules so operations keep running.

We've heard every New Hampshire horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.

We're not routing your call through a national center — the person who answers is close by.
Our major repairs come with written, transferable warranties — useful if you sell the New Hampshire property later.

We can supply the documentation most carriers ask for before approving a New Hampshire claim.
Every New Hampshire job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our New Hampshire work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
