Who We Are

Arrow Tight Waterproofing has spent years earning a reputation in Lemont 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 IL, 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 Lemont.

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

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

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.

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.

An overworked sump pump is a warning sign in itself — it's compensating for something upstream.

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

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

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

We don't push a single product — every job starts with a diagnosis, then a recommendation matched to what's actually happening at your property.

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

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

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.

Frequently Asked Questions

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

How fast can a Waterproofing technician arrive in Lemont, IL?+
Active water intrusion moves to priority scheduling, and most Lemont, IL 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?+
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?+
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?+
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?+
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?+
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?+
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?+
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.
