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.
Our Sumner crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
📞 +1-866-476-1348Most Sumner calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Sumner crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
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.
These upstairs clues usually show up months after the basement moisture problem actually started.
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 →We seal active Sumner foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
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 →Older Sumner homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.

Every Sumner quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.

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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
Every Sumner technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
