Ask around in Shelby 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.
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.
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.
Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.
A musty smell that returns no matter how often you clean the basement.
Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.
A door frame that's suddenly out of square, or a window that won't close flush, can point to foundation movement.
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.
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.
If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.
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.
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.
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.
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. 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.
Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Shelby.
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.
We understand active seepage doesn't wait for a convenient slot, so emergency calls get dispatched immediately with equipment already loaded.
Every quote breaks out material, labor, and equipment separately, delivered in writing before any drilling or coring begins.
We run a full moisture survey — wall cameras, hydrostatic pressure readings, crack classification — before recommending any specific system.
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.
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.
The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.
Pricing reflects exactly what the diagnostic found, not a generic package.
Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.
Feedback from real Waterproofing customers across Shelby, NC.
"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."
