Arrow Tight Waterproofing has spent years earning a reputation in Gastonia 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 NC, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.
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.
Transparency doesn't end once the quote is signed — we walk you through what was actually done once the crew finishes, not just what was proposed at the start.
Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.
If the basement smell comes back within days of airing it out, that's moisture, not just staleness.
Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.
Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.
Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.
Standing water or damp carpet after any significant rainfall.
A sump pump that runs constantly, or one that hasn't been tested in years.
Bowing or leaning foundation walls, even subtle ones you can check with a level.
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.
Every service below starts from the same diagnostic-first approach, whether the job is a small crack injection or a full exterior excavation.
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.
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.
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.
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.
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.
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.
A basement actively taking on water moves to the front of the schedule — most Gastonia, NC service areas see a technician within hours, not days.
Pricing is based on what our diagnostic actually finds, not a generic per-square-foot estimate pulled out of thin air.
Technicians are trained to identify the real entry point, not just treat the most visible symptom.
Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.
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.
You'll see exactly what the equipment finds — this isn't a sales walkthrough, it's a real inspection.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
We test drain tile flow, pump activation, and injection fill before the crew leaves the property.
What homeowners in Gastonia, NC 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."
