Halo Water Proofing has been the trusted call for Exterior Waterproofing across Sumner because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in WA · Written pricing
Halo Water Proofing started small in the Sumner area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
We don't run a bidding war between crews. The Sumner technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Sumner homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Sumner technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Sumner crews hear about most.
A musty smell usually means moisture is already moving through your Sumner basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Sumner schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Sumner basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Sumner emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp Sumner crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We handle below-grade waterproofing for Sumner property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →Here's exactly what Sumner customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Sumner property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
The number you approve is the number you're billed — no change orders once the crew shows up.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Sumner horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
Our crews stage locally near Sumner, which is why most emergency calls get a technician on-site in under two hours.
Our major repairs come with written, transferable warranties — useful if you sell the Sumner property later.
We'd rather earn a repeat Sumner customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Sumner job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Sumner work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
