We built SGP Waterproofing around one idea: a Morton, WA property owner shouldn't have to wait three days for someone to look at a wet wall.

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Morton, WA. We didn't start as a marketing company that added waterproofing to a service list — our crews came up running sump pumps, pouring interior drain tile, and injecting epoxy into foundation cracks long before the trucks had our name on the door.
Our dispatchers know the difference between a slow seep that can wait until morning and an active flood that can't, and they route calls accordingly. That triage system is the reason our average Morton, WA response time beats most of the national franchises operating in the same zip codes.
Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Morton, WA's mix of clay-heavy and sandy soils behaves differently depending on the neighborhood, sometimes block to block. A crew that hasn't worked the area tends to size drainage systems using generic assumptions instead of what's actually under the yard.
We also see a lot of properties where a previous waterproofing attempt only addressed the symptom — a topical sealant painted over a cracked wall, for example — without solving the pressure or grading issue causing the crack in the first place. Part of every Morton, WA inspection is checking for that kind of prior patch job before we recommend anything new.

Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Morton, WA's seasonal moisture swings tend to speed the timeline up.
That damp, earthy smell in a finished or unfinished basement is usually mold or mildew feeding on moisture that's already gotten past your walls.
Those white, chalky mineral deposits on block or poured concrete walls are salt left behind after water has migrated through the concrete and evaporated.
Small stair-step cracks in block walls or vertical hairline cracks in poured walls tend to widen over a season or two as hydrostatic pressure keeps pushing.
Drywall that feels soft, bubbles, or shows a tide line near the floor is already absorbing groundwater — by the time you see it, the insulation behind it is usually soaked too.
If your window wells hold water for more than an hour after a storm, that water has nowhere to go but toward the seal around your basement window.
Water that pools against your foundation after every rain is telling you the drainage system, whatever's left of it, has stopped doing its job.
We scope every Morton, WA job in person before quoting it, because two houses with the same symptom rarely need the same fix. These are the five services that make up most of our workload.
When a sump pump fails during a storm or a foundation wall gives way, we dispatch a crew with portable pumps and extraction equipment within hours, not days.
Interior drain tile systems, sump pump installation, and vapor barrier wall systems make up the bulk of our residential basement work across Morton, WA neighborhoods.
We work with property managers on phased scheduling so a commercial waterproofing retrofit doesn't shut down an entire building at once.
Crack injection is often the most cost-effective Morton, WA repair when the crack is isolated and the wall itself hasn't bowed or shifted.
A properly encapsulated crawl space with its own sump discharge line keeps humidity below the threshold where wood rot and mold can take hold.
We trace surface water back to its source, which is often a downspout discharging too close to the foundation or a grade that slopes the wrong direction entirely.
A dispatcher walks through symptoms with you on the phone so the crew that shows up already has a rough idea what they're dealing with.
We walk the interior and exterior with a moisture meter and flashlight, tracing water back to its actual entry point instead of guessing.
We put the scope, materials, and price in writing so you can compare it against anyone else's estimate line for line.
Once installation wraps, we test the sump pump under load and walk you through the warranty paperwork before we leave the site.
Every quote breaks down materials and labor separately, so you can see exactly what you're paying for instead of one vague lump sum.
Local staffing means the technician answering your call today can usually be on-site the same day, not on a waitlist behind out-of-town jobs.
Every technician trains on interior drain tile installation, sump system sizing, and crack classification before they lead a job on their own.
Warranty callbacks get the same dispatch priority as a new emergency, because a repeat leak is still an active problem for you.

Every interior drainage system, sump installation, and crack repair we complete in Morton, WA comes with a written, transferable warranty — useful if you sell the property before the coverage period ends.


Our Morton coverage area extends through most of the surrounding Morton, WA communities. Give us a call even if your address falls just outside the zone below; we'll let you know honestly if we can reach you same-day.

Most Morton, WA emergency calls get a technician on-site within a few hours; non-urgent inspections are typically scheduled within one to two business days.
Yes — every job gets a flat-rate, written quote before work begins, and that number doesn't change once the crew is on-site.
We handle active flooding, sump pump failures, and failed foundation walls with same-day dispatch, portable extraction pumps, and temporary water mitigation.
Cost depends on square footage, the type of system needed, and whether the fix is interior drainage, exterior membrane work, or both — we won't quote a number without an in-person inspection first.
Hairline cracks are actually the ideal time to call, since injection repair is faster and cheaper before hydrostatic pressure has a chance to widen the gap.
The right system depends on access, budget, and what's actually driving the water in — we'll explain the trade-offs before you decide.
We give you a realistic timeline in the written quote so you can plan around the crew being on-site.
We can document moisture readings, photos, and scope of damage to support an insurance claim, though coverage and claim approval are ultimately determined by your carrier.
We can walk your specific setup during an inspection and tell you honestly whether your existing drain needs a pump added.
We back our work with a written, often transferable warranty — useful if you sell the property before the coverage period runs out.
Standing water doesn't stop us from starting; we extract it as the first step, then proceed with vapor barrier and drainage installation.
We work with property managers, HOAs, and commercial building owners across Morton, WA in addition to single-family homes, including parking structures and multi-unit basements.
