Arrow Tight Waterproofing has spent years earning a reputation in Decatur 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 MI, 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 Decatur.
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.
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.
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.
Hold a level against your foundation wall — even a small deviation from plumb is worth having evaluated.
Rising humidity readings in the basement that a dehumidifier can't keep up with.
Rust or corrosion on metal fixtures, HVAC components, or stored tools in the basement.
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.
When water is actively rising, extraction comes first — high-capacity pumps clear standing water while we map exactly where it's entering. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.
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.
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.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
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.
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.
Five things that actually separate a specialized Waterproofing crew from a general contractor with a truck and a sump pump on hand.
Anyone can put a truck on the road and call it Waterproofing service; what separates a crew worth trusting is what happens once they're standing in front of your foundation.
A basement actively taking on water moves to the front of the schedule — most Decatur, MI service areas see a technician within hours, not days.
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.
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.
Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.
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.
You'll receive an itemized, written quote broken down by system component before agreeing to anything.
We test drain tile flow, pump activation, and injection fill before the crew leaves the property.
Feedback from real Waterproofing customers across Decatur, MI.
"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."
