Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Lewisville, WA basements.

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.
We're bonded and insured for both residential and light commercial basement work across Lewisville, WA.
Our Lewisville, WA crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
The core fix for most Lewisville, WA basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.
Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.
Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.
A technician walks the basement with a moisture meter, checking walls, floor, and cove joints to trace the water back to its actual source.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
