From emergency extraction to permanent drain tile systems, we diagnose the real problem before recommending a fix.

Arrow Tight Waterproofing has spent years earning a reputation across Washington, WA for showing up when a basement is taking on water and not leaving until it's actually fixed.
Our field teams hold real Waterproofing credentials and are licensed in WA, with training that covers moisture mapping, sump system design, and foundation crack evaluation in depth.
We run a dispatch-first model: local crews stocked with diagnostic gear and repair materials, ready to move on active water intrusion the same day it's reported.
We believe a homeowner should be able to see the evidence behind a recommendation, not just take our word for it — every diagnostic visit comes with documented findings you can keep.
Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.
That persistent musty odor downstairs almost always traces back to trapped moisture somewhere in the wall or floor assembly.
Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.
Doors and windows that stick or won't latch properly, especially on the lowest level.
Stair-step cracking in a block wall usually signals something more than simple concrete shrinkage.
Standing water or damp carpet after any significant rainfall.
If you can't remember the last time your sump pump was tested, that's worth addressing before the next storm does it for you.
Bowing or leaning foundation walls, even subtle ones you can check with a level.
If your basement dehumidifier is running around the clock and humidity still creeps up, the moisture source needs addressing, not just managing.
Unexplained rust forming on tools or ductwork is often the first physical evidence of chronically elevated humidity.
We don't push a single product — every job starts with a diagnosis, then a recommendation matched to what's actually happening at your property.
When water is actively rising, extraction comes first — high-capacity pumps clear standing water while we map exactly where it's entering. Extraction is never treated as the finish line — it's the first step toward a lasting repair.
This is the most common permanent fix for hydrostatic pressure seepage — proven, code-recognized, and installed without exterior excavation. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.
We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. Injection resin fills the full depth of the crack, not just the visible surface.
This is the most thorough fix available and typically carries the longest service life, though it's not always necessary depending on what the interior diagnostic finds.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
A properly sized primary pump paired with a battery backup is the last line of defense against basement flooding when the power goes out during a storm. Cellular notification add-ons alert your phone directly if the system is ever triggered.
For walls showing early bowing alongside seepage, carbon fiber straps or steel wall anchors can arrest further movement before it becomes a bigger structural concern. We explain the engineering rationale before recommending any wall reinforcement work.
Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing across Washington, WA.
Anyone can put a truck on the road and call it Waterproofing service; what separates a crew worth trusting is what happens once they're standing in front of your foundation.
A basement actively taking on water moves to the front of the schedule — most Washington, WA service areas see a technician within hours, not days.
Pricing is based on what our diagnostic actually finds, not a generic per-square-foot estimate pulled out of thin air.
A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.
Below-grade water intrusion work is a distinct trade, and our technicians are trained and certified specifically in it, not treating it as a side skill.
Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.
We keep the process consistent for every single job so you always know exactly what to expect next, whether it's an emergency call or a scheduled inspection.
One call connects you to local dispatch, not a national call center — they'll ask a few questions to understand what you're seeing and prioritize accordingly.
A technician arrives with moisture meters, a wall camera, and a hydrostatic pressure gauge to identify the actual entry point, not just the visible symptom.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.
Feedback from real Waterproofing customers across Washington, WA.
"Had standing water after a spring storm and they had a full drain tile system installed within the week. Completely dry since."
"They showed us the actual crack on camera before recommending anything — nobody had ever bothered to look that closely before."
"Quote matched the final invoice to the dollar. No surprise line items once they opened up the wall."
"Battery backup pump they installed kept us dry through a multi-hour outage last winter. Would've flooded otherwise."
"Appreciated that they told us plainly our crack needed an engineer's eyes before injecting anything — didn't just upsell us."
"Crawl space encapsulation got rid of a musty smell we'd been dealing with for two years. Should've called sooner."
"They walked us through the moisture readings on the spot instead of just telling us to trust them. Made the whole decision easier."
"Sump pump replacement was done same-day after our old one failed during a storm. Genuinely impressed with the response time."
"We got three other quotes before calling them, and theirs was the only one that actually explained why our specific wall was leaking."
"Vapor barrier install in our crawl space was clean, fast, and the humidity reading dropped noticeably within a couple weeks."
