Who We Are

Who We Are: A Licensed Waterproofing Crew in Allentown

Arrow Tight Waterproofing exists because too many property owners in Allentown were getting patchwork fixes instead of real diagnosis. Our crews are licensed in NJ, carry full liability coverage, and are trained to find the actual water path before recommending anything.

We've built our reputation in Allentown 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.

We keep detailed job records for every property in Allentown 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.

  • 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

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 Allentown.

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

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.

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

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.

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.

From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Allentown.

01

Emergency Water Intrusion Response

When water is actively entering a property in Allentown, 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 Allentown, 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

Commercial foundations in Allentown 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.

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.

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.

05

Sump Pump & Discharge System Upgrades

A waterproofing system is only as reliable as the pump moving water out of it — we size, install, and upgrade sump systems in Allentown to match actual groundwater volume rather than defaulting to whatever's in stock.

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.

Why Arrow Tight Waterproofing

The Arrow Tight Waterproofing Standard, in Allentown

These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.

Upfront, Itemized Pricing

Pricing surprises are the single biggest complaint we hear about competitors, so we built our proposal process specifically to eliminate them.

Fast Local Dispatch

We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Allentown isn't driving hours to get there.

Satisfaction Backed in Writing

Every completed system comes with a written, transferable warranty — not a verbal promise that's hard to enforce two years later.

Commercial-Grade Materials, Every Time

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.

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.

Our Process

How a Waterproofing Job Works With Us

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

A certified technician inspects the property with thermal imaging and moisture meters, mapping the actual water path before recommending anything.

03

Written, Fixed-Price Proposal

You receive an itemized proposal before any work begins — materials, labor, and scope laid out in writing, not estimated verbally.

04

Installation & Warranty Documentation

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

Customer Reviews

Verified Feedback From Our Customers

24/7 Emergency Waterproofing experts in Allentown, 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, Allentown
★★★★★

"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, Allentown
★★★★★

"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, Allentown
★★★★★

"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."

M. — Homeowner, Allentown
★★★★★

"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, Allentown
★★★★★

"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."

L. — Property Manager, Allentown
FAQ

Waterproofing Frequently Asked Questions

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.
We document every job with photos and moisture readings you can submit for any claim, regardless of what your policy ultimately covers.
Timeline depends entirely on scope — we give you a written schedule estimate as part of the proposal so there's no ambiguity going in.
A technician inspects the property directly with thermal imaging and moisture meters before any number is put on paper.
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 Allentown, 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.
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.
