Arrow Tight Waterproofing has spent years earning a reputation in Sullivan 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 IN, 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 Sullivan.
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.
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.
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.
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.
Bowing or leaning foundation walls, even subtle ones you can check with a level.
A hygrometer reading that stays above 60% no matter how much you run a dehumidifier usually points to an active intrusion source.
If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.
From emergency response to permanent structural fixes, here's the full range of work our crews handle in Sullivan.
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.
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.
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.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
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. Cellular notification add-ons alert your phone directly if the system is ever triggered.
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.
Five things that actually separate a specialized Waterproofing crew from a general contractor with a truck and a sump pump on hand.
It's easy to promise fast, honest Waterproofing service in an ad — the real test is whether that promise holds up once a technician is actually standing in your basement.
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.
Technicians are trained to identify the real entry point, not just treat the most visible symptom.
Certification covers the specific systems we install — drain tile, sump basins, exterior membranes — not general construction knowledge alone.
We stand behind installed systems with documented warranty terms included in your quote, not a verbal promise that's hard to pin down later.
Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.
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.
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.
You'll receive an itemized, written quote broken down by system component before agreeing to anything.
A written warranty and, where relevant, a post-storm follow-up check come standard with every completed installation.
Feedback from real Waterproofing customers across Sullivan, IN.
"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."
