From emergency extraction to permanent drain tile systems, we diagnose the real problem before recommending a fix.

Ask around in Lemont 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 Waterproofing credentials and are licensed in PA, with training that covers moisture mapping, sump system design, and foundation crack evaluation in depth.
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.
Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.
A musty smell that returns no matter how often you clean the basement.
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.
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.
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.
From emergency response to permanent structural fixes, here's the full range of work our crews handle in Lemont.
Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. Extraction is never treated as the finish line — it's the first step toward a lasting repair.
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.
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.
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.
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.
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.
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.
Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Lemont.
A lot of companies claim to offer Waterproofing, but the difference shows up in how the job is actually diagnosed and executed — not in the advertising.
We understand active seepage doesn't wait for a convenient slot, so emergency calls get dispatched immediately with equipment already loaded.
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.
A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.
Certification covers the specific systems we install — drain tile, sump basins, exterior membranes — not general construction knowledge alone.
Warranty coverage is spelled out before work begins, so there's no ambiguity about what's protected and for how long.
Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.
Describe the issue — a damp wall, standing water, a musty smell — and dispatch routes the right crew with matching equipment.
The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.
What homeowners in Lemont, PA are saying after calling us for Waterproofing.
"Had standing water after a spring storm and they had a full drain tile system installed within the week. Completely dry since."
"They showed us the actual crack on camera before recommending anything — nobody had ever bothered to look that closely before."
"Quote matched the final invoice to the dollar. No surprise line items once they opened up the wall."
"Battery backup pump they installed kept us dry through a multi-hour outage last winter. Would've flooded otherwise."
"Appreciated that they told us plainly our crack needed an engineer's eyes before injecting anything — didn't just upsell us."
"Crawl space encapsulation got rid of a musty smell we'd been dealing with for two years. Should've called sooner."
"They walked us through the moisture readings on the spot instead of just telling us to trust them. Made the whole decision easier."
"Sump pump replacement was done same-day after our old one failed during a storm. Genuinely impressed with the response time."
"We got three other quotes before calling them, and theirs was the only one that actually explained why our specific wall was leaking."
"Vapor barrier install in our crawl space was clean, fast, and the humidity reading dropped noticeably within a couple weeks."
Answers to the questions homeowners ask most before booking Waterproofing service.
Coverage is built around regional dispatch hubs rather than a single central office, which is exactly why response times in Lemont stay competitive.
Coverage isn't limited to single-family homes — your Lemont home with a finished basement, a crawl space, or a commercial foundation all fall within our service scope.
Property size changes the scope of the work, not the rigor of the diagnostic — every job gets the same moisture survey before a single recommendation is made.
Coverage boundaries shift as we bring on new regional crews, so a quick call to +1-866-476-1348 is always the most current answer.
