Arrow Tight Waterproofing diagnoses the real cause before quoting anything — thermal imaging, moisture readings, and a written fixed price in Hornell.
📞 Call Now — Free EstimateWe started Arrow Tight Waterproofing after years of watching homeowners get sold vague 'waterproofing packages' that never named the actual problem. Every technician we send in Hornell is licensed, background-checked, and trained to diagnose before quoting — not the other way around.
We've built our reputation in Hornell on jobs that don't need a second visit. That means slower quoting sometimes, since we're inspecting properly instead of estimating from a driveway conversation, but it also means fewer callbacks.
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.

Waiting until you see standing water means you've already missed the cheaper fix. These are the early signals our crews are trained to catch in Hornell.
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.
Continuous cycling means your pump is handling more groundwater than it was sized for, and it's only a matter of time before it fails under the load.
Measuring wall deflection with a level is one of the first things we do on any inspection where bowing is suspected, since the degree of lean changes the recommended fix.
This sign often gets dismissed as cosmetic, but it points to water reaching structural steel, which is a different severity than surface dampness.
By the time drywall is visibly damaged, the moisture behind it has usually been present for weeks or months already.
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 Hornell gets a scope built around what our inspection actually finds.

When water is actively entering a property in Hornell, 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 Hornell, 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 Hornell, we coordinate around occupied units and business hours, minimizing disruption while still delivering a full waterproofing scope.
Commercial jobs get the same commercial-grade materials as our residential work — nothing scaled down because the client is a business instead of a homeowner.
📞 Get a Free Quote →Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Hornell 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 →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 →These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.
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.
Response time isn't an afterthought for us — it's a scheduling metric we track and staff around, not just a marketing line.
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.
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.
If the proposal includes options — say, interior versus exterior drainage — we'll walk through the tradeoffs so you're deciding with full information.
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.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.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.Would recommend them without hesitation."
