Halo Water Proofing has been the trusted call for Exterior Waterproofing across Boston because we answer the phone, show up when we say, and stand behind the work.
Free, no-obligation estimates ยท 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.
We don't run a bidding war between crews. The Boston technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Boston 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 โ not a vague callback promise.
๐ +1-866-476-1348Most Boston calls didn't start with a flood โ 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.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Boston crews handle most.
Storm season keeps our Boston emergency line busy โ active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help โWe seal active Boston foundation cracks with hydraulic cement injection โ stopping the leak at its source instead of patching the surface.
Ask About Crack Repair โA failed sump pump is the top reason for emergency calls across Boston after heavy rain โ we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check โAn interior drain tile system routes water to a sump pump before it reaches your Boston basement floor at all.
Talk Drainage Options โA damp Boston crawl space drives up humidity throughout the house โ we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote โWe handle below-grade waterproofing for Boston property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote โNo pressure, no scripts โ 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 Boston property before anyone drives out.
No jargon, no pressure โ just a clear look at what's actually going on.
The number you approve is the number you're billed โ no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Boston 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 โ what you approve is what you're billed.
We're not routing your call through a national center โ the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
Our technicians are trained to diagnose accurately, not to upsell โ that changes the advice you actually get.
Filing a claim can be confusing โ we've walked Boston customers through this process many times.
Every Boston 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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"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 โ no arguing, no extra invoice. That's written into every Boston contract we sign.
