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.

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.

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

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

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.

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.

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

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.

Our Waterproofing Services in Lemont

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

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

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

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

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. 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

High-intent questions we hear most from Waterproofing customers across Lemont, IL.

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?+
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?+
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?+
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?+
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?+
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.
