Who We Are

Local Waterproofing Specialists Who've Already Seen Your Problem Before

We're a licensed, insured Waterproofing outfit built around Cheney, WA properties specifically — the clay-heavy soil, the seasonal freeze-thaw cycles, the older basements with parged walls that were never meant to hold back a modern water table. Every technician on our crew has logged real hours crawling through wet crawl spaces, not just reading about them.

We keep our crews local rather than routing calls through a national call center, which means the technician who answers your questions on the phone is often the same person standing in your basement two hours later. That continuity cuts down on the miscommunication that drags out so many waterproofing jobs.

  • Licensed and fully insured for residential and commercial work
  • On call every night of the year, not just business hours
  • Written quotes with no hidden change orders

Older Cheney, WA neighborhoods often have block foundations poured decades before modern drainage codes existed, while newer subdivisions tend to run poured concrete with a perimeter drain that was installed correctly but has since clogged with silt. Knowing which era of construction you're dealing with changes the repair plan before a single tool comes out of the truck.

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 Cheney, WA inspection is checking for that kind of prior patch job before we recommend anything new.

Problem Signs

How to Tell a Foundation Problem Is Getting Worse, Not Better

Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Cheney, WA's seasonal moisture swings tend to speed the timeline up.

Sign 01

Musty Basement Odor

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.

Sign 02

White Powdery Efflorescence

Efflorescence forms when water carries dissolved minerals through porous concrete and leaves them on the surface as it dries — a clear sign moisture is actively passing through.

Sign 03

Hairline Wall Cracks

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.

Sign 04

Damp or Bubbling Drywall

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.

Sign 05

Window Well Flooding

A window well that fills with water during heavy rain is putting direct pressure on the glass and frame, and it's one of the most common entry points we find in older Cheney, WA homes.

Sign 06

Standing Water After Storms

Puddling near the foundation that doesn't drain within a few hours usually means grading, gutters, or a failing perimeter drain — and it's the fastest path to a flooded basement.

What We Do

The Waterproofing Work Cheney, WA Property Owners Call Us For Most

We scope every Cheney, 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.

Emergency

Emergency Waterproofing & Flood Response

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.

Residential

Residential Basement Waterproofing

Most Cheney, WA basements need a combination of interior drainage and a properly sized sump pump — we size the system to your square footage and soil type, not a one-size-fits-all package.

Commercial

Commercial & Multi-Unit Waterproofing

We coordinate directly with building engineers and HOA boards so the scope, timeline, and access requirements are agreed on before a crew ever shows up on-site.

Foundation

Foundation Crack Repair & Injection

Low-pressure epoxy injection bonds structural cracks back together, while polyurethane injection is better suited for cracks that are still actively leaking.

Crawl Space

Crawl Space Encapsulation & Sump Systems

We install heavy-gauge vapor barriers, seal foundation vents, and add a dedicated sump basin so a damp Cheney, WA crawl space stops feeding moisture into the floor joists above it.

Drainage

Exterior Grading & French Drain Systems

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.

How It Works

What Actually Happens After You Call SGP Waterproofing

01

Call & Phone Assessment

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.

02

On-Site Inspection

We walk the interior and exterior with a moisture meter and flashlight, tracing water back to its actual entry point instead of guessing.

03

Written Quote

You get a flat-rate, itemized quote before any work starts — no verbal estimate that changes once the crew shows up.

04

Installation & Walkthrough

Most residential jobs finish in one to three days, and we walk the property with you afterward to confirm every drain, pump, and seal is working.

FAQ

What Cheney, WA Customers Ask Us Most Often

How fast can a Waterproofing technician arrive in Cheney, WA?▼

Most Cheney, WA emergency calls get a technician on-site within a few hours; non-urgent inspections are typically scheduled within one to two business days.

Do you provide upfront pricing?▼

Yes — every job gets a flat-rate, written quote before work begins, and that number doesn't change once the crew is on-site.

What emergency services are available?▼

Our emergency response covers water extraction, temporary pump-outs, and emergency crack sealing to stop active intrusion until permanent repairs are scheduled.

How much does basement waterproofing typically cost?▼

Pricing varies with scope, but every Cheney, WA customer gets an itemized written estimate before any work is authorized, so there's never a guessing game.

Will you repair hairline foundation cracks or only large cracks?▼

We repair cracks of nearly any size — hairline cracks are often the easiest and least expensive to seal with polyurethane or epoxy injection before they widen.

Do you offer interior or exterior waterproofing systems?▼

We install both — interior drain tile and sump systems for most residential jobs, and exterior membrane or French drain systems when the source is surface water or when excavation is practical.

How long does a typical waterproofing job take?▼

Most residential interior drain tile or sump installations finish in one to three days; larger commercial membrane projects can take longer depending on square footage.

Do you work with insurance claims for water damage?▼

We're happy to provide the documentation adjusters typically request, though we recommend confirming your specific coverage details directly with your insurance provider.

Is a sump pump necessary if I already have a French drain?▼

A French drain without a sump pump just relocates water to one spot; the pump is what actually discharges it away from the home.

Do you offer a warranty on your waterproofing work?▼

Warranty length and coverage vary by service type, and we'll spell out the specifics in writing before the job starts.

Can you waterproof a crawl space with standing water already present?▼

We assess the water depth and source first, since active groundwater intrusion changes how we sequence the encapsulation work.

Do you service commercial properties as well as homes?▼

Yes — our commercial work covers parking garages, retail basements, and multi-family buildings, usually scheduled in phases to minimize tenant disruption.
