Who We Are

Arrow Tight Waterproofing has spent years earning a reputation in Mount Vernon for showing up when a basement is taking on water and not leaving until it's actually fixed.

Licensing here isn't a formality — every crew member is licensed in WA and specifically trained in the below-grade water intrusion work that Waterproofing actually requires.

Response speed matters as much as technique in this trade, which is why our regional crews carry sump pumps, injection resin, and extraction equipment on every truck.

Transparency doesn't end once the quote is signed — we walk you through what was actually done once the crew finishes, not just what was proposed at the start.

Warning Signs You Shouldn't Wait On

Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.

If the basement smell comes back within days of airing it out, that's moisture, not just staleness.

White, chalky staining on block or poured concrete walls — a mineral deposit called efflorescence.

Doors and windows that stick or won't latch properly, especially on the lowest level.

Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.

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.

Rising humidity readings in the basement that a dehumidifier can't keep up with.

If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.

Our Waterproofing Services in Mount Vernon

Every service below starts from the same diagnostic-first approach, whether the job is a small crack injection or a full exterior excavation.

24/7 Emergency Waterproofing experts in Mount Vernon, WA

Emergency Water Extraction & Stabilization

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.

Interior Drain Tile & Sump Systems

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.

Foundation Crack Injection

Non-structural cracks respond well to polyurethane or epoxy injection depending on whether water is actively present and whether the crack is still moving. Injection resin fills the full depth of the crack, not just the visible surface.

Exterior Excavation & Membrane Application

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.

Crawl Space Encapsulation & Vapor Control

We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.

Sump Pump Installation & Battery Backup

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.

Wall Vapor Barrier & Structural Reinforcement

Dimple-board membrane installed against a foundation wall creates an air gap that channels incidental moisture down to a collection point instead of letting it wick into finished drywall. We explain the engineering rationale before recommending any wall reinforcement work.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across Mount Vernon, WA.

How fast can a Waterproofing technician arrive in Mount Vernon, WA?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Mount Vernon, WA.
Do you provide upfront, flat-rate pricing?+
You'll know the full cost before work starts; nothing gets added mid-job without your sign-off first.
Will interior drain tile actually stop the water, or just hide it?+
It's a proven, code-recognized method for managing hydrostatic pressure, not a cosmetic fix that just moves the problem out of sight.
Do I need exterior excavation or can interior work solve it?+
We evaluate both approaches during the diagnostic and recommend whichever solves the actual entry point with the least disruption.
What's the difference between a hairline crack and a structural one?+
A hairline crack is typically under an eighth of an inch and stable — a good candidate for injection. A structural crack shows displacement or is still widening and needs engineering evaluation first.
Is waterproofing work covered by a warranty?+
Warranty terms are included in your written quote before work begins, so there's no ambiguity about what's covered.
How long does a typical installation take?+
Exterior excavation projects take longer, typically several days, depending on wall section length and access.
Do you work on older homes with existing foundation issues?+
Yes, older foundations are some of the most common jobs we handle, and our diagnostic accounts for aging materials and previous repair attempts.
What causes a basement to flood in the first place?+
Hydrostatic pressure from groundwater, poor exterior grading, a failed sump pump, or a combination of all three are the most common causes we diagnose.
Can you help with insurance documentation after a flood?+
We document extraction and mitigation work with photos, moisture readings, and timestamps you can include with a claim.
Do you offer emergency service outside business hours?+
Yes, emergency dispatch operates continuously for active flooding and failed sump pumps, including nights and weekends.
Can you work with my homeowner's insurance claim directly?+
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.
Do I need to be home during the diagnostic visit?+
Yes, we ask that someone be present so the technician can walk the findings through with you directly before any recommendation is made.
What's the first sign I should call about, even if it seems minor?+
A musty smell that keeps returning, or a hairline crack that's new, are both worth a call before they become bigger problems.
Do you offer any kind of maintenance check after installation?+
We're glad to do a post-storm follow-up check after a significant rain event to confirm the system is performing as designed.
Will waterproofing work lower my homeowner's insurance premium?+
Some insurers do offer discounts for documented flood mitigation work — we can provide the paperwork, though the discount itself depends on your specific policy and carrier.
Do you offer financing for larger projects?+
Financing availability depends on project scope; smaller single-system jobs are usually straightforward flat-rate, while larger combination repairs sometimes qualify for financing.
How do I know if I actually need waterproofing or just better gutters?+
If water is reaching your foundation wall itself, gutters alone usually aren't enough; we'll tell you honestly if a smaller fix like downspout extension would solve it.
Do you guarantee your work in writing, not just verbally?+
Yes, every installed system — drain tile, sump, injection, exterior membrane — comes with written warranty terms included in your quote before work begins.
What should I do right now if water is actively coming in?+
Call +1-866-476-1348 immediately — dispatch will walk you through basic mitigation steps while routing the nearest available emergency crew to your address.
