The Arrow Tight Waterproofing Story — Built by Waterproofing Specialists, Not Salespeople

Too many contractors in Longport 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.

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 Longport, 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 NJ 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

How to Tell If your Longport property Needs Attention Now

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 Longport.

01

Efflorescence on Basement Walls

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.

02

A Musty Smell That Won't Go Away

Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.

03

Cracks Along the Wall-Floor Joint

The cove joint is the single most common water entry point in basements — staining or gaps there usually mean hydrostatic pressure is pushing water in.

04

A Sump Pump That Never Stops Running

We treat constant cycling as an early warning, not a normal condition — the pump working overtime today is the pump failing sooner than expected.

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

This sign often gets dismissed as cosmetic, but it points to water reaching structural steel, which is a different severity than surface dampness.

07

Peeling Paint or Soft Drywall Near the Floor

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.

08

Cold, Damp Floors Above a Crawl Space

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.

Core Services

Complete Waterproofing Solutions, in Longport

We don't sell a single fixed package — every property in Longport gets a scope built around what our inspection actually finds.

01

Emergency Water Intrusion Response

When water is actively entering a property in Longport, 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.

02

Residential Basement & Crawl Space Systems

For homeowners in Longport, 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.

03

Commercial & Multi-Unit Waterproofing

For property managers in Longport, 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.

04

Specialized Structural & Foundation Repair

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.

05

Sump Pump & Discharge System Upgrades

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.

Why Arrow Tight Waterproofing

What Actually Sets Us Apart in Longport

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

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.

Our Process

What to Expect When You Call Arrow Tight Waterproofing

01

Call or Request an Inspection

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.

02

On-Site Diagnosis

We document every visible entry point and pressure indicator during the visit — this is what the eventual proposal is built around.

03

Written, Fixed-Price Proposal

Review the proposal at your own pace; we don't pressure same-visit sign-off, though we can often start within days once approved.

04

Installation & Warranty Documentation

Once the system is installed and tested, you get warranty paperwork that transfers with the property if you ever sell.

Water Problems Don't Fix Themselves

Customer Reviews

Real Reviews From Real Waterproofing Jobs

24/7 Emergency Waterproofing experts in Longport, NJ
★★★★★

"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."

R. — Homeowner, Longport
★★★★★

"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."

K. — Emergency Client, Longport
★★★★★

"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.Exactly the level of service we expected."

T. — Property Manager, Longport
★★★★★

"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."

M. — Homeowner, Longport
★★★★★

"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."

D. — Homeowner, Longport
★★★★★

"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."

FAQ

What Longport, NJ 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.
Emergency response covers active flooding, sudden sump failure, and burst pipe water intrusion — we stabilize the situation first, then scope the permanent repair.
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.
Coverage extends across Longport — call +1-866-476-1348 to confirm your specific address, though it's almost certainly within our service area.
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 proper fix starts with identifying the pressure source or entry mechanism, then installs a system rated to handle it permanently, not just plug the spot you can see.
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission, which you can include with your own claim.
