Who We Are

Ask around across New York, NY and you'll find Arrow Tight Waterproofing mentioned by name — not because of an ad, but because a crew showed up, found the real problem, and fixed it the first time.

Our field teams hold real Exterior Waterproofing credentials and are licensed in NY, 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.

Warning Signs You Shouldn't Wait On

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

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

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

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

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

If a heavy storm reliably means a wet spot on the basement floor, that's a pattern, not bad luck.

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.

A hygrometer reading that stays above 60% no matter how much you run a dehumidifier usually points to an active intrusion source.

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

Core Exterior Waterproofing Solutions across New York, NY

From emergency response to permanent structural fixes, here's the full range of work our crews handle across New York, NY.

24/7 Emergency Exterior Waterproofing experts in New York, NY

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

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.

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

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.

Why New York, NY Homeowners Choose Arrow Tight Waterproofing

Five things that actually separate a specialized Exterior Waterproofing crew from a general contractor with a truck and a sump pump on hand.

A lot of companies claim to offer Exterior Waterproofing, but the difference shows up in how the job is actually diagnosed and executed — not in the advertising.

1

Same-Day Response for Active Intrusion

A basement actively taking on water moves to the front of the schedule — most New York, NY service areas see a technician within hours, not days.

2

Written, Itemized Pricing — No Surprises

You'll know the exact cost before work starts — no hourly guessing games, no mid-job upcharges for what a proper inspection should have caught.

3

Diagnosis Before Recommendation, Always

A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.

4

Licensed Specialists, Not General Contractors

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

5

Written Warranty on Every Installed System

We stand behind installed systems with documented warranty terms included in your quote, not a verbal promise that's hard to pin down later.

How a Exterior Waterproofing Project Actually Works

Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.

1

Call & Triage

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.

2

On-Site Diagnostic Visit

The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.

3

Written Quote & Scheduling

Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.

4

Installation & Verification

We test drain tile flow, pump activation, and injection fill before the crew leaves the property.

Frequently Asked Questions

High-intent questions we hear most from Exterior Waterproofing customers across New York, NY.

How fast can a Exterior Waterproofing technician arrive in New York, NY?+
Active water intrusion moves to priority scheduling, and most New York, NY service areas see a technician within hours of the call.
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?+
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?+
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?+
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?+
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 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?+
A live dispatcher answers emergency calls at any hour — water damage doesn't wait for business hours and neither do we.
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?+
Sump systems in particular benefit from an annual check, which we can schedule as a simple follow-up visit.
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?+
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?+
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.
