Certified Waterproofing crews in Hilliard, backed by a written warranty and same-day emergency dispatch.
📞 Speak With a SpecialistArrow Tight Waterproofing exists because too many property owners in Hilliard were getting patchwork fixes instead of real diagnosis. Our crews are licensed in OH, carry full liability coverage, and are trained to find the actual water path before recommending anything.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Hilliard — 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 Hilliard.
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.
Odor alone rarely tells you the source, but it's a reliable sign something needs a real moisture inspection rather than an air freshener.
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.
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
A wall that's no longer plumb is telling you the soil outside is pushing harder than the wall was built to resist.
Iron doesn't rust without sustained water contact, so rust bleeding through concrete is a reliable indicator of ongoing penetration.
If the bottom foot of drywall in a below-grade room feels soft or the paint is bubbling, that's usually vapor transmission through the wall, not a plumbing leak.
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 Hilliard gets a scope built around what our inspection actually finds.

Active flooding doesn't wait for business hours, and neither do we — our emergency line in Hilliard is answered live, 24 hours a day, with crews dispatched to stop the immediate entry point first.
We carry the equipment needed to control an active situation immediately, then scope the permanent fix once the emergency is under control.
📞 Get a Free Quote →For homeowners in Hilliard, 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 Hilliard, 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 Hilliard showing signs of settlement or lateral pressure.
Every structural repair is documented with before-and-after photos and moisture readings as part of your warranty file.
📞 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 Hilliard to match actual groundwater volume rather than defaulting to whatever's in stock.
We also correct discharge line routing and grading as part of any pump job, since a poorly graded discharge line often just recirculates water back toward the foundation.

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.
Crews are staged regionally in Hilliard specifically to keep response times short — most inspections are scheduled within days, and emergencies get same-day priority.
Warranty documentation is registered to the property address, so it transfers automatically if you sell, without needing to track us down for paperwork.
Our sump pumps are cast iron, our drain tile is schedule 40 PVC, and our membranes are rated for sustained hydrostatic pressure — not hardware-store equivalents.
We inspect with thermal imaging and moisture meters before quoting anything, because a scope built on a guess is a scope that often needs redoing.
Call +1-866-476-1348 and describe the issue. We route the right technician for your specific situation rather than a generalist.
We document every visible entry point and pressure indicator during the visit — this is what the eventual proposal is built around.
You receive an itemized proposal before any work begins — materials, labor, and scope laid out in writing, not estimated verbally.
Our crew completes the approved scope, verifies the fix with post-install moisture readings, and hands you written warranty documentation registered to the property.
Free on-site inspection, written estimate, no obligation. We answer 24/7.

"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.That's the kind of fix that actually holds up."
"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.Would recommend them without hesitation."
"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.Exactly the level of service we expected."
"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.That's the kind of fix that actually holds up."
"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.That's the kind of fix that actually holds up."
