From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Somerville before. We show up, we diagnose it straight, and we fix it right.

Halo Water Proofing started as a small OH crew and grew because Somerville customers kept referring us to neighbors — that's still how most of our work comes in today.

Every technician on our Somerville crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Somerville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Somerville customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your Somerville foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Somerville every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Somerville emergency crews remove the water first, then diagnose where it's getting in so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Somerville basements start leaking. We use hydraulic cement injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →Most sump pump failures we see in Somerville happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Somerville basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Older Somerville homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →Commercial properties in Somerville carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Somerville property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Somerville job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Our trucks stage locally around Somerville, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
If your Somerville basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Somerville, OH carriers ask for before approving a claim.
Our name is on trucks driving around Somerville every day — we don't cut corners on a job our neighbors will see.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
