Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Somerville property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates ยท 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.
Our Somerville crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Somerville 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 Somerville calls didn't start with a flood โ they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Somerville basement, even if the floor looks bone dry.
Small cracks in a Somerville foundation rarely stay small โ seasonal ground movement tends to widen them over time.
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.
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.
Whatever's going on with your Somerville property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast โ extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help โWe seal active Somerville 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 Somerville after heavy rain โ we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check โFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options โMusty smell upstairs with no obvious source? Check the crawl space first โ it's usually the culprit.
Get a Crawl Space Quote โCommercial water intrusion means bigger stakes โ inventory, tenants, downtime. We scope commercial Somerville jobs with written specs and a real timeline.
Request a Commercial Quote โNo pressure, no scripts โ just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script โ enough of a conversation to know what to expect before anyone shows up.
A Somerville technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
Every Somerville 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 Somerville 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.
If your Somerville basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Somerville customers find us, which keeps our standards high.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything โ 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."
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 Somerville contract we sign.
