Who We Are

Arrow Tight Waterproofing: Straight Answers, Real Fixes, throughout Oregon, OR

Too many contractors throughout Oregon, OR sell a fix before they've actually confirmed what's wrong. Arrow Tight Waterproofing built its process around the opposite order: inspect first, document what we find, and only then put a number on paper.

Our technicians carry thermal cameras and calibrated moisture meters to every inspection, because guessing at a foundation problem wastes your money and our reputation. That's the standard for every job throughout Oregon, OR, residential or commercial.

We keep detailed job records for every property throughout Oregon, OR we've serviced, which means if you call back in three years with a question about your system, we can pull the exact specs of what was installed rather than starting from scratch.

  • IICRC-certified technicians on every job, no exceptions
  • licensed in OR with full liability and workers' comp coverage
  • Thermal imaging and calibrated moisture readings before every quote
  • Written, transferable warranty on all completed systems
  • Direct-employee crews — never subcontracted out

Warning Signs

How to Tell If properties throughout Oregon, OR Needs Attention Now

Waiting until you see standing water means you've already missed the cheaper fix. These are the early signals our crews are trained to catch throughout Oregon, OR.

01

Efflorescence on Basement Walls

That chalky white residue on concrete or block isn't dirt — it's mineral salt left behind after water has already migrated through the wall.

02

A Musty Smell That Won't Go Away

If a dehumidifier only masks the smell instead of fixing it, there's an active moisture source somewhere in the structure.

03

Cracks Along the Wall-Floor Joint

This is the exact spot our technicians check first on every basement inspection, because it tells us more about the pressure situation than almost anywhere else.

04

A Sump Pump That Never Stops Running

A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.

05

Bowing or Leaning Foundation Walls

Measuring wall deflection with a level is one of the first things we do on any inspection where bowing is suspected, since the degree of lean changes the recommended fix.

06

Rust Stains Bleeding Through Concrete

Iron doesn't rust without sustained water contact, so rust bleeding through concrete is a reliable indicator of ongoing penetration.

07

Peeling Paint or Soft Drywall Near the Floor

If the bottom foot of drywall in a below-grade room feels soft or the paint is bubbling, that's usually vapor transmission through the wall, not a plumbing leak.

08

Cold, Damp Floors Above a Crawl Space

Floors that stay cold and slightly damp-feeling even with the heat running usually trace back to an open or failed vapor barrier beneath the house, not an HVAC problem.

Specialized Structural & Foundation Repair

Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties throughout Oregon, OR showing signs of settlement or lateral pressure.

We're upfront when a problem needs structural engineering input beyond what waterproofing alone can fix, rather than selling a repair that won't hold.

05

Sump Pump & Discharge System Upgrades

Failed or undersized sump pumps are one of the most common reasons a previously working system suddenly floods, and we treat pump sizing as its own diagnostic step, not an afterthought to drainage work.

Battery backup and monitored alarm options are available on every pump we install, so a power outage during a storm doesn't leave the system unprotected.

Why Arrow Tight Waterproofing

The Arrow Tight Waterproofing Standard, throughout Oregon, OR

These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.

Upfront, Itemized Pricing

The number on your proposal is the number on your invoice — materials, labor, and scope are itemized before any work begins, with no surprise line items added mid-job.

Fast Local Dispatch

Response time isn't an afterthought for us — it's a scheduling metric we track and staff around, not just a marketing line.

Satisfaction Backed in Writing

Every completed system comes with a written, transferable warranty — not a verbal promise that's hard to enforce two years later.

Commercial-Grade Materials, Every Time

Our sump pumps are cast iron, our drain tile is schedule 40 PVC, and our membranes are rated for sustained hydrostatic pressure — not hardware-store equivalents.

Diagnosis Before Recommendation

A diagnosis-first approach costs us more time per estimate, but it's the reason our repeat-callback rate is a fraction of the industry average.

Customer Reviews

Verified Feedback From Our Customers

24/7 Emergency Wet Basement Repair experts in Oregon, OR
★★★★★

"Had a cove joint leak that two other companies just patched without explaining why it kept happening. Arrow Tight Waterproofing's technician showed me the moisture readings and traced it to hydrostatic pressure, then installed drain tile that's held through every storm since.That's the kind of fix that actually holds up."

R. — Homeowner, Oregon, OR
★★★★★

"Called at 11 PM with active water coming in during a storm. Live person answered immediately, crew was on-site within the hour, and they had a temporary pump running before starting the real diagnosis.Would recommend them without hesitation."

K. — Emergency Client, Oregon, OR
★★★★★

"We manage a small multi-unit building and needed the work scheduled around tenants. They coordinated everything cleanly and the commercial-grade membrane they used has zero callbacks two years later.That's the kind of fix that actually holds up."

T. — Property Manager, Oregon, OR
★★★★★

"Appreciated that they didn't just sell us a package. The inspection actually found the real problem — a bowing block wall — and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.Would recommend them without hesitation."

M. — Homeowner, Oregon, OR
★★★★★

"Sump pump had been cycling nonstop for weeks before we called. They correctly diagnosed it as undersized for our actual water table and upgraded it — no more constant cycling, and it's kept up with two heavy storms since.Exactly the level of service we expected."

D. — Homeowner, Oregon, OR
★★★★★

"We're a small property management company and needed drainage work done across three units without disrupting tenants. Arrow Tight Waterproofing scheduled around occupied hours, communicated clearly with residents, and the itemized invoice matched the original proposal exactly.Exactly the level of service we expected."

FAQ

Straight Answers About Wet Basement Repair

Standard inspections are typically scheduled within a few days of your call; active emergencies get same-day priority dispatch in most of our coverage area.
We never bill hourly or open-ended. The fixed price you approve in writing is the price on the final invoice, barring a documented scope change you sign off on first.
Our emergency line is answered live 24/7, and crews carry equipment for immediate water extraction, temporary sump deployment, and active crack sealing on the first visit.
Interior drainage manages water after it enters at the wall-floor joint; exterior waterproofing stops it from reaching the wall at all. Our inspection determines which fits your specific situation.
Gradual groundwater seepage is typically treated as a maintenance issue and excluded, while sudden events like burst pipes are often covered — check your specific policy language.
Crack injection is usually a few hours; interior drain tile runs 1 to 3 days depending on perimeter footage; full exterior excavation can run 2 to 5 days depending on depth.
Always an in-person inspection — we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Yes — every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
We provide Wet Basement Repair services throughout Oregon, OR, with regionally staged crews that keep response times reasonable across the footprint we serve.
For the initial inspection, yes — we need access to the affected area and it helps to walk through what we're seeing together, though the visit is usually under an hour.
A proper fix starts with identifying the pressure source or entry mechanism, then installs a system rated to handle it permanently, not just plug the spot you can see.
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission, which you can include with your own claim.
