Arrow Tight Waterproofing: Straight Answers, Real Fixes, in Jericho
Arrow Tight Waterproofing exists because too many property owners in Jericho were getting patchwork fixes instead of real diagnosis. Our crews are licensed in NY, 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 Jericho, residential or commercial.
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.
IICRC-certified technicians on every job, no exceptions
licensed in NY with full liability and workers' comp coverage
Thermal imaging and calibrated moisture readings before every quote
Written, transferable warranty on all completed systems
Direct-employee crews — never subcontracted out
Warning Signs
Six Warning Signs You Shouldn't Ignore
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 Jericho.
01
Efflorescence on Basement Walls
White powdery buildup on a foundation wall means water has been passing through it, even if the surface looks dry today.
02
A Musty Smell That Won't Go Away
If a dehumidifier only masks the smell instead of fixing it, there's an active moisture source somewhere in the structure.
03
Cracks Along the Wall-Floor Joint
Cracking where your floor meets the foundation wall is rarely cosmetic; it's typically the first visible sign of pressure building against the wall.
04
A Sump Pump That Never Stops Running
A sump that runs nonstop during rain is a system working past its design limit, not a system doing its job well.
05
Bowing or Leaning Foundation Walls
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.
06
Rust Stains Bleeding Through Concrete
Iron doesn't rust without sustained water contact, so rust bleeding through concrete is a reliable indicator of ongoing penetration.
07
Peeling Paint or Soft Drywall Near the Floor
By the time drywall is visibly damaged, the moisture behind it has usually been present for weeks or months already.
08
Cold, Damp Floors Above a Crawl Space
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.
Core Services
What Arrow Tight Waterproofing Handles in Jericho
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Jericho.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we — our emergency line in Jericho is answered live, 24 hours a day, with crews dispatched to stop the immediate entry point first.
Every emergency truck carries submersible pumps, temporary sump units, and crack-sealing materials, so most active leaks can be stabilized on the first visit.
For homeowners in Jericho, 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.
Commercial foundations in Jericho 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.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Jericho 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.
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.
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.
These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.
Upfront, Itemized Pricing
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.
Fast Local Dispatch
Response time isn't an afterthought for us — it's a scheduling metric we track and staff around, not just a marketing line.
Satisfaction Backed in Writing
Warranty documentation is registered to the property address, so it transfers automatically if you sell, without needing to track us down for paperwork.
Commercial-Grade Materials, Every Time
We install the same membrane specification, pipe schedule, and pump ratings on residential jobs that commercial contracts require — never a downgraded consumer-grade substitute.
Diagnosis Before Recommendation
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.

What Customers Say About Arrow Tight Waterproofing
★★★★★
"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."
R. — Homeowner, Jericho
★★★★★
"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."
K. — Emergency Client, Jericho
★★★★★
"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."
T. — Property Manager, Jericho
★★★★★
"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.Would recommend them without hesitation."
M. — Homeowner, Jericho
★★★★★
"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."
D. — Homeowner, Jericho
★★★★★
"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."
L. — Property Manager, Jericho
FAQ
What Jericho, NY Customers Ask Us Most
Standard inspections are typically scheduled within a few days of your call; active emergencies get same-day priority dispatch in most of our coverage area.
Yes — every job gets a written, itemized proposal after a real on-site inspection, and that number is what you're invoiced, not an estimate that grows once work starts.
Our emergency line is answered live 24/7, and crews carry equipment for immediate water extraction, temporary sump deployment, and active crack sealing on the first visit.
If interior fixes haven't held or the wall shows active exterior deterioration, exterior waterproofing is usually the better long-term answer — we'll tell you honestly which applies.
Gradual groundwater seepage is typically treated as a maintenance issue and excluded, while sudden events like burst pipes are often covered — check your specific policy language.
Crack injection is usually a few hours; interior drain tile runs 1 to 3 days depending on perimeter footage; full exterior excavation can run 2 to 5 days depending on depth.
Always an in-person inspection — we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Yes — every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
We provide Waterproofing services in Jericho, with regionally staged crews that keep response times reasonable across the footprint we serve.
For the initial inspection, yes — we need access to the affected area and it helps to walk through what we're seeing together, though the visit is usually under an hour.
A patch treats the visible symptom — a caulked crack, a coat of sealant — without addressing why water found that path in the first place, so the same issue often resurfaces nearby.
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.
Service Area
Our Service Footprint, in Jericho
We built our coverage in Jericho around regional crew staging rather than one central office, which keeps dispatch times shorter across the footprint we serve.
Same-day or next-day scheduling is typically available for non-emergency inspections, with active flooding calls prioritized ahead of the standard queue.
Coverage isn't limited to single-family homes — we service condos, multi-unit rentals, and small commercial buildings in Jericho using the same diagnostic-first process regardless of property type.
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.
