Certified Waterproofing crews in Gastonia, backed by a written warranty and same-day emergency dispatch.
📞 Call Now — Free EstimateToo many contractors in Gastonia sell a fix before they've actually confirmed what's wrong. Arrow Tight Waterproofing built its process around the opposite order: inspect first, document what we find, and only then put a number on paper.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Gastonia — no subcontractors, no handoffs, no one new showing up halfway through.
Every technician completes ongoing training as materials and methods evolve — the polyurethane injection resin we use today isn't the same formulation the industry relied on ten years ago, and neither is our crew's training.

Most foundation failures don't start as floods — they start small, and they're easy to miss until the damage compounds. Here's what our technicians look for on every inspection in Gastonia.
That chalky white residue on concrete or block isn't dirt — it's mineral salt left behind after water has already migrated through the wall.
Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.
This is the exact spot our technicians check first on every basement inspection, because it tells us more about the pressure situation than almost anywhere else.
We treat constant cycling as an early warning, not a normal condition — the pump working overtime today is the pump failing sooner than expected.
A wall that's no longer plumb is telling you the soil outside is pushing harder than the wall was built to resist.
This sign often gets dismissed as cosmetic, but it points to water reaching structural steel, which is a different severity than surface dampness.
Paint and drywall absorb moisture vapor before liquid water ever becomes visible, so bubbling or soft spots near the baseboard are an early-stage signal, not a late one.
Floors that stay cold and slightly damp-feeling even with the heat running usually trace back to an open or failed vapor barrier beneath the house, not an HVAC problem.
We don't sell a single fixed package — every property in Gastonia gets a scope built around what our inspection actually finds.

When water is actively entering a property in Gastonia, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
Every emergency truck carries submersible pumps, temporary sump units, and crack-sealing materials, so most active leaks can be stabilized on the first visit.
📞 Get a Free Quote →For homeowners in Gastonia, we install interior drain tile, sump systems, and crawl space encapsulation sized to your property's actual groundwater load — not a one-size package.
Every residential install includes post-job moisture verification, so you have documented proof the system is working, not just our word for it.
📞 Get a Free Quote →For property managers in Gastonia, we coordinate around occupied units and business hours, minimizing disruption while still delivering a full waterproofing scope.
We provide the same written, itemized proposals for commercial clients as residential ones, with the added documentation many property managers need for ownership or insurance records.
📞 Get a Free Quote →Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Gastonia showing signs of settlement or lateral pressure.
We're upfront when a problem needs structural engineering input beyond what waterproofing alone can fix, rather than selling a repair that won't hold.
📞 Get a Free Quote →A waterproofing system is only as reliable as the pump moving water out of it — we size, install, and upgrade sump systems in Gastonia to match actual groundwater volume rather than defaulting to whatever's in stock.
Battery backup and monitored alarm options are available on every pump we install, so a power outage during a storm doesn't leave the system unprotected.
📞 Get a Free Quote →Every waterproofing company claims to be the best. Here's what we actually do differently, and why it holds up under scrutiny.
The number on your proposal is the number on your invoice — materials, labor, and scope are itemized before any work begins, with no surprise line items added mid-job.
We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Gastonia isn't driving hours to get there.
If something about the completed work doesn't meet the scope we agreed to, we return and correct it under the warranty terms, in writing.
We install the same membrane specification, pipe schedule, and pump ratings on residential jobs that commercial contracts require — never a downgraded consumer-grade substitute.
Our technicians document the actual water path and pressure source before recommending a fix, so you're paying for the right repair the first time.
There's no charge for the call or the inspection that follows, so there's no downside to getting a second opinion even if you've already spoken with another contractor.
Expect the inspection itself to take 45 to 90 minutes depending on property size and how many areas need checking.
Review the proposal at your own pace; we don't pressure same-visit sign-off, though we can often start within days once approved.
Our crew completes the approved scope, verifies the fix with post-install moisture readings, and hands you written warranty documentation registered to the property.
Our crews are ready to assess your property today — call now.

"Had a cove joint leak that two other companies just patched without explaining why it kept happening. Arrow Tight Waterproofing's technician showed me the moisture readings and traced it to hydrostatic pressure, then installed drain tile that's held through every storm since.Exactly the level of service we expected."
"Called at 11 PM with active water coming in during a storm. Live person answered immediately, crew was on-site within the hour, and they had a temporary pump running before starting the real diagnosis.That's the kind of fix that actually holds up."
"We manage a small multi-unit building and needed the work scheduled around tenants. They coordinated everything cleanly and the commercial-grade membrane they used has zero callbacks two years later.That's the kind of fix that actually holds up."
"Appreciated that they didn't just sell us a package. The inspection actually found the real problem — a bowing block wall — and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.That's the kind of fix that actually holds up."
"Sump pump had been cycling nonstop for weeks before we called. They correctly diagnosed it as undersized for our actual water table and upgraded it — no more constant cycling, and it's kept up with two heavy storms since.Would recommend them without hesitation."
"We're a small property management company and needed drainage work done across three units without disrupting tenants. Arrow Tight Waterproofing scheduled around occupied hours, communicated clearly with residents, and the itemized invoice matched the original proposal exactly.Exactly the level of service we expected."
We built our coverage in Gastonia around regional crew staging rather than one central office, which keeps dispatch times shorter across the footprint we serve.
Call +1-866-476-1348 to confirm coverage for your specific address — given our regional staging in Gastonia, it's very likely within our service area.
Whether your property in Gastonia has a finished basement, an unfinished crawl space, or a slab foundation, our crews carry the equipment and training to assess and quote all three foundation types on the same visit.
New service areas are added as we expand our regional crew staging, so if you were told we didn't cover your address in the past, it's worth checking again.
