Who We Are

We built Arrow Tight Waterproofing on a simple premise: waterproofing work in Port Washington should be diagnosed correctly the first time, not sold as a guess and revisited three times.

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

A basement filling with water doesn't wait for a convenient appointment, so our dispatch model is built around same-day response for active seepage in Port Washington.

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

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

That persistent musty odor downstairs almost always traces back to trapped moisture somewhere in the wall or floor assembly.

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

A door frame that's suddenly out of square, or a window that won't close flush, can point to foundation movement.

Even a crack thinner than a coin can be an active entry point once hydrostatic pressure builds behind the wall.

Puddling near the same wall section after every storm points to a specific, fixable entry point.

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

Hold a level against your foundation wall — even a small deviation from plumb is worth having evaluated.

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.

Core Waterproofing Solutions in Port Washington

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

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. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.

Interior Drain Tile & Sump Systems

A perimeter drain tile channel installed below the slab intercepts groundwater before it can reach your floor, routing it to a properly sized sump basin and pump. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.

Foundation Crack Injection

We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. Photos and measurements are logged before and after every injection for your records.

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

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

We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Backup systems activate automatically the instant the primary loses power or falls behind.

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.

Frequently Asked Questions

Answers to the questions homeowners ask most before booking Waterproofing service.

How fast can a Waterproofing technician arrive in Port Washington, NY?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Port Washington, NY.
Do you provide upfront, flat-rate pricing?+
Yes — every quote is written and itemized by system component before any coring or excavation begins.
Will interior drain tile actually stop the water, or just hide it?+
Drain tile intercepts groundwater below the slab and routes it to a sump basin before it reaches the finished space — it addresses the water at the source.
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?+
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?+
We assess existing conditions carefully on older homes since prior DIY fixes sometimes mask the real problem.
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'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?+
Efflorescence — that white chalky residue on concrete — is an easy one to miss but worth addressing early.
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?+
It varies by insurer, but a documented drain tile or sump installation is worth mentioning to your agent when you renew.
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?+
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?+
Call +1-866-476-1348 immediately — dispatch will walk you through basic mitigation steps while routing the nearest available emergency crew to your address.
