Who We Are

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

Every technician on our roster is Exterior Waterproofing-certified and licensed in PA, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.

We run a dispatch-first model: local crews stocked with diagnostic gear and repair materials, ready to move on active water intrusion the same day it's reported.

We believe a homeowner should be able to see the evidence behind a recommendation, not just take our word for it — every diagnostic visit comes with documented findings you can keep.

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.

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

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.

Stair-step cracking in a block wall usually signals something more than simple concrete shrinkage.

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.

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

If your basement dehumidifier is running around the clock and humidity still creeps up, the moisture source needs addressing, not just managing.

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

Our Exterior Waterproofing Services across Pennsylvania, PA

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

24/7 Emergency Exterior Waterproofing experts in Pennsylvania, PA

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

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. 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

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.

Why Pennsylvania, PA 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

We understand active seepage doesn't wait for a convenient slot, so emergency calls get dispatched immediately with equipment already loaded.

2

Written, Itemized Pricing — No Surprises

Every quote breaks out material, labor, and equipment separately, delivered in writing before any drilling or coring begins.

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

Below-grade water intrusion work is a distinct trade, and our technicians are trained and certified specifically in it, not treating it as a side skill.

5

Written Warranty on Every Installed System

Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.

How a Exterior 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

Active water intrusion is flagged for priority scheduling right at this first call.

2

On-Site Diagnostic Visit

You'll see exactly what the equipment finds — this isn't a sales walkthrough, it's a real inspection.

3

Written Quote & Scheduling

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

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 Pennsylvania, PA.

How fast can a Exterior Waterproofing technician arrive in Pennsylvania, PA?+
Active water intrusion moves to priority scheduling, and most Pennsylvania, PA service areas see a technician within hours of the call.
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?+
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?+
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?+
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?+
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?+
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?+
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?+
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.
