Who We Are

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

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 Ithaca.

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

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.

Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.

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.

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.

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.

Unexplained rust forming on tools or ductwork is often the first physical evidence of chronically elevated humidity.

Our Waterproofing Services in Ithaca

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

24/7 Emergency Waterproofing experts in Ithaca, 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. 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

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. Photos and measurements are logged before and after every injection for your records.

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

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

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 Ithaca, NY Homeowners Choose Arrow Tight Waterproofing

Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Ithaca.

Anyone can put a truck on the road and call it Waterproofing service; what separates a crew worth trusting is what happens once they're standing in front of your foundation.

1

Same-Day Response for Active Intrusion

A basement actively taking on water moves to the front of the schedule — most Ithaca, 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

We run a full moisture survey — wall cameras, hydrostatic pressure readings, crack classification — before recommending any specific system.

4

Licensed Specialists, Not General Contractors

Certification covers the specific systems we install — drain tile, sump basins, exterior membranes — not general construction knowledge alone.

5

Written Warranty on Every Installed System

Warranty coverage is spelled out before work begins, so there's no ambiguity about what's protected and for how long.

How a Waterproofing Project Actually Works

No mystery about what happens after you pick up the phone — here's the exact sequence from first call to a finished, fully tested repair, start to end.

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

A technician arrives with moisture meters, a wall camera, and a hydrostatic pressure gauge to identify the actual entry point, not just the visible symptom.

3

Written Quote & Scheduling

You'll receive an itemized, written quote broken down by system component before agreeing to anything.

4

Installation & Verification

A written warranty and, where relevant, a post-storm follow-up check come standard with every completed installation.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across Ithaca, NY.

How fast can a Waterproofing technician arrive in Ithaca, NY?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Ithaca, NY.
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?+
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?+
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?+
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission.
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?+
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?+
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.
