Who We Are

Arrow Tight Waterproofing has spent years earning a reputation in Ontario 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 OR, with training that covers moisture mapping, sump system design, and foundation crack evaluation in depth.

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.

Beyond the repair itself, we document every diagnostic finding with photos and moisture readings, so you understand exactly what was found and why a given system was recommended.

Signs Your Foundation Is Already Fighting Water

Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.

A musty smell that returns no matter how often you clean the basement.

Chalky white streaks on your foundation wall are a visible sign that water has been passing through the concrete itself.

Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.

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

Standing water or damp carpet after any significant rainfall.

A sump pump that runs constantly, or one that hasn't been tested in years.

A wall that bows inward even slightly is responding to soil pressure that isn't going away on its own.

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

Rust or corrosion on metal fixtures, HVAC components, or stored tools in the basement.

Our Waterproofing Services in Ontario

From emergency response to permanent structural fixes, here's the full range of work our crews handle in Ontario.

24/7 Emergency Waterproofing experts in Ontario, OR

Emergency Water Extraction & Stabilization

Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. 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

Where the source is grading, a failed footing drain, or membrane failure visible from outside, exterior excavation and a rubberized membrane address the problem at its origin.

Crawl Space Encapsulation & Vapor Control

A sealed, encapsulated crawl space with a reinforced vapor barrier cuts off the ground moisture that feeds humidity, mold, and wood rot before it ever reaches your living space.

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

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.

Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across Ontario, OR.

How fast can a Waterproofing technician arrive in Ontario, OR?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Ontario, OR.
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?+
Most seepage from hydrostatic pressure is fully addressable with interior drain tile — excavation is usually reserved for grading or membrane failures visible from outside.
What's the difference between a hairline crack and a structural one?+
We classify every crack during inspection; if it looks like it's still moving, we won't just inject it and call it done.
Is waterproofing work covered by a warranty?+
Yes, drain tile, sump, and injection installations all carry a written warranty against failure at the treated location.
How long does a typical installation take?+
Interior drain tile installations are usually completed in one to two days depending on perimeter length.
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?+
Every property is different — our diagnostic identifies your specific combination of contributing factors rather than assuming a single cause.
Can you help with insurance documentation after a flood?+
We're not public adjusters, but our documentation is formatted to support whatever your insurer's claim process requires.
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?+
Being present lets you see the moisture readings and camera footage firsthand rather than getting a secondhand summary.
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?+
We work with a few financing partners for larger combination projects — ask your technician during the quote and they'll walk you through current options.
How do I know if I actually need waterproofing or just better gutters?+
Poor gutter drainage is a common contributing factor, but it's rarely the whole story — our diagnostic checks both grading and foundation condition before recommending a fix.
Do you guarantee your work in writing, not just verbally?+
We put warranty coverage in writing specifically because verbal promises are hard to enforce months or years later when you actually need them.
What should I do right now if water is actively coming in?+
Move valuables away from the affected area if it's safe to do so, then call +1-866-476-1348 so extraction can begin as soon as a crew arrives.
