Arrow Tight Waterproofing has spent years earning a reputation in Madison for showing up when a basement is taking on water and not leaving until it's actually fixed.
Every technician on our roster is Waterproofing-certified and licensed in NJ, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.
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 Madison.
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.
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.
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.
If your basement dehumidifier is running around the clock and humidity still creeps up, the moisture source needs addressing, not just managing.
If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.
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.
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. Photos and measurements are logged before and after every injection for your records.
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.
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. 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.
Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Madison.
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.
We run a full moisture survey — wall cameras, hydrostatic pressure readings, crack classification — before recommending any specific system.
Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.
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.
Active water intrusion is flagged for priority scheduling right at this first call.
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.
What homeowners in Madison, NJ 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."
