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

Halo Water Proofing is a licensed and insured Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

Every technician on our Lake Oswego 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 Lake Oswego 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."
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 Lake Oswego 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.
These signs upstairs are often the last clue Lake Oswego homeowners notice, even though the moisture issue started in the basement months earlier.
Every Lake Oswego property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Lake Oswego basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Freeze-thaw cycles in Lake Oswego, OR 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 Lake Oswego 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 Lake Oswego 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 →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Lake Oswego crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We work directly with Lake Oswego property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Lake Oswego crews follow on every job.
You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Lake Oswego property.
A technician inspects the Lake Oswego 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 Lake Oswego 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.
A local dispatch model means the technician who answers questions about your Lake Oswego job is the same one who shows up to do it.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Word of mouth is still how most Lake Oswego customers find us, which keeps our standards higher than a big out-of-town franchise.
"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."
"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."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
