Certified Waterproofing crews in Cynthiana, backed by a written warranty and same-day emergency dispatch.
📞 Speak With a SpecialistArrow Tight Waterproofing exists because too many property owners in Cynthiana 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.
Our technicians carry thermal cameras and calibrated moisture meters to every inspection, because guessing at a foundation problem wastes your money and our reputation. That's the standard for every job in Cynthiana, residential or commercial.
We keep detailed job records for every property in Cynthiana we've serviced, which means if you call back in three years with a question about your system, we can pull the exact specs of what was installed rather than starting from scratch.

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 Cynthiana.
We see this most often on walls that look completely dry to the touch — the salt deposit is evidence of past water movement, not current dampness.
Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.
Cracking where your floor meets the foundation wall is rarely cosmetic; it's typically the first visible sign of pressure building against the wall.
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
Even a slight inward lean in a block wall signals lateral soil pressure building against the foundation — this needs structural evaluation, not just a sealant.
Rust streaks mean water has reached embedded rebar or metal lath and started oxidizing it — a sign moisture has penetrated deeper than the surface.
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.
Persistent cold-floor complaints in homes with a crawl space are one of the most common calls we get, and encapsulation resolves them far more often than a furnace repair does.
We don't sell a single fixed package — every property in Cynthiana gets a scope built around what our inspection actually finds.

When water is actively entering a property in Cynthiana, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
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 Cynthiana, 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 →Commercial foundations in Cynthiana carry different risk than residential ones — larger footprints, tenant liability, and often tighter access — and our crews scope and schedule around that.
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 →When a foundation issue is structural rather than purely a water problem, we bring in the crack-classification and reinforcement expertise that basic waterproofing crews don't carry.
Every structural repair is documented with before-and-after photos and moisture readings as part of your warranty file.
📞 Get a Free Quote →Failed or undersized sump pumps are one of the most common reasons a previously working system suddenly floods, and we treat pump sizing as its own diagnostic step, not an afterthought to drainage work.
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.
📞 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.
We quote a fixed price after a real inspection, not a phone estimate, and we get written sign-off before any change to that scope.
Response time isn't an afterthought for us — it's a scheduling metric we track and staff around, not just a marketing line.
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.
A diagnosis-first approach costs us more time per estimate, but it's the reason our repeat-callback rate is a fraction of the industry average.
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.
A certified technician inspects the property with thermal imaging and moisture meters, mapping the actual water path before recommending anything.
If the proposal includes options — say, interior versus exterior drainage — we'll walk through the tradeoffs so you're deciding with full information.
We also walk you through basic maintenance for whatever was installed, so you know what to check twice a year to keep the system performing as designed.
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.Would recommend them without hesitation."
"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.Would recommend them without hesitation."
"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.Exactly the level of service we expected."
"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.Would recommend them without hesitation."
