The Arrow Tight Waterproofing Story — Built by Waterproofing Specialists, Not Salespeople
We 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 Sewaren is licensed, background-checked, and trained to diagnose before quoting — not the other way around.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Sewaren — no subcontractors, no handoffs, no one new showing up halfway through.
We keep detailed job records for every property in Sewaren 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 Sewaren.
01
Efflorescence on Basement Walls
That chalky white residue on concrete or block isn't dirt — it's mineral salt left behind after water has already migrated through the wall.
02
A Musty Smell That Won't Go Away
Odor alone rarely tells you the source, but it's a reliable sign something needs a real moisture inspection rather than an air freshener.
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
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
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.
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
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 Sewaren
We don't sell a single fixed package — every property in Sewaren gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we — our emergency line in Sewaren 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 Sewaren, 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 Sewaren carry different risk than residential ones — larger footprints, tenant liability, and often tighter access — and our crews scope and schedule around that.
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.
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.
A waterproofing system is only as reliable as the pump moving water out of it — we size, install, and upgrade sump systems in Sewaren to match actual groundwater volume rather than defaulting to whatever's in stock.
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 Property Owners in Sewaren Choose Arrow Tight Waterproofing
Every waterproofing company claims to be the best. Here's what we actually do differently, and why it holds up under scrutiny.
Upfront, Itemized Pricing
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.
Fast Local Dispatch
We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Sewaren 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
Material selection isn't where we compete on price — we'd rather lose a bid than install something we know will fail in a few years.
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
If the proposal includes options — say, interior versus exterior drainage — we'll walk through the tradeoffs so you're deciding with full information.
04
Installation & Warranty Documentation
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.

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.Would recommend them without hesitation."
R. — Homeowner, Sewaren
★★★★★
"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.Exactly the level of service we expected."
K. — Emergency Client, Sewaren
★★★★★
"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.That's the kind of fix that actually holds up."
T. — Property Manager, Sewaren
★★★★★
"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, Sewaren
★★★★★
"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.That's the kind of fix that actually holds up."
D. — Homeowner, Sewaren
★★★★★
"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.Exactly the level of service we expected."
L. — Property Manager, Sewaren
FAQ
Straight Answers About Waterproofing
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.
We never bill hourly or open-ended. The fixed price you approve in writing is the price on the final invoice, barring a documented scope change you sign off on first.
Emergency response covers active flooding, sudden sump failure, and burst pipe water intrusion — we stabilize the situation first, then scope the permanent repair.
Interior drainage manages water after it enters at the wall-floor joint; exterior waterproofing stops it from reaching the wall at all. Our inspection determines which fits your specific situation.
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.
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.

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.
