Halo Water Proofing has been the Sherwood area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.

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

We don't send apprentices to figure it out on your dime. Every Sherwood job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Sherwood customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Sherwood winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Sherwood foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Sherwood storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Sherwood call we prioritize fast.
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 Sherwood every day.
Storm season in Sherwood, OR means our emergency line gets busy fast — we triage calls by severity so active flooding at your Sherwood address jumps the queue ahead of routine inspections.
Call for Emergency Service →Hairline cracks are how most Sherwood basements start leaking. We use polyurethane 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 →Already have a sump pump that's failing or too small for your Sherwood 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 →Some Sherwood lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →A damp, uninsulated crawl space under a Sherwood 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 →Commercial properties in Sherwood 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 walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Sherwood property — the written estimate is the final word.

Our repairs come with written, transferable warranties — a real asset if you sell the Sherwood property later.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.

"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."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"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."
