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.

We're Halo Water Proofing — a NJ-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Somerville-area foundations, and exactly how to stop it.

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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Somerville technicians hear about most often before an inspection.
Odor is often the first sign Somerville customers notice, well before any visible water shows up.
Hairline cracks can widen over a Somerville winter's freeze-thaw cycle and become active leak points by spring.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Somerville lot's water table.
This is one sign we tell Somerville customers not to wait on — wall movement tends to progress rather than resolve on its own.
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.
Storm season in Somerville, NJ means our emergency line gets busy fast — we triage calls by severity so active flooding at your Somerville address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Somerville, NJ push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Somerville lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
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 →A damp, uninsulated crawl space under a Somerville home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We can phase larger Somerville commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Somerville crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Somerville job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
A local dispatch model means the technician who answers questions about your Somerville job is the same one who shows up to do it.
Our repairs come with written, transferable warranties — a real asset if you sell the Somerville property later.
If your Somerville basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
Filing a water damage claim in Somerville, NJ can be confusing — we've done it enough times with Somerville adjusters to help you avoid common denials.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
