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

Every technician on our Westport 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 Westport customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
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 Westport 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.
Flooring that's cupping or warping near an exterior wall is a common clue our Westport crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Westport every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Westport 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 →Freeze-thaw cycles in Westport, WA push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.

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 Westport 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 Westport 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.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Because we're actually based near Westport rather than routing calls through a national center, we can usually get someone out the same day you call.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
