Who We Are

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 Westchester 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 Westchester — no subcontractors, no handoffs, no one new showing up halfway through.

We keep detailed job records for every property in Westchester 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 IL 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

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 Westchester.

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

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

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

A wall that's no longer plumb is telling you the soil outside is pushing harder than the wall was built to resist.

06

Rust Stains Bleeding Through Concrete

Rust streaks mean water has reached embedded rebar or metal lath and started oxidizing it — a sign moisture has penetrated deeper than the surface.

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 Westchester

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

01

Emergency Water Intrusion Response

When water is actively entering a property in Westchester, 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 Westchester, 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 Westchester, 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.

04

Specialized Structural & Foundation Repair

Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Westchester 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.

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

The Arrow Tight Waterproofing Standard, in Westchester

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

Crews are staged regionally in Westchester specifically to keep response times short — most inspections are scheduled within days, and emergencies get same-day priority.

Satisfaction Backed in Writing

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.

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

Expect the inspection itself to take 45 to 90 minutes depending on property size and how many areas need checking.

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

Our crew completes the approved scope, verifies the fix with post-install moisture readings, and hands you written warranty documentation registered to the property.

Water Problems Don't Fix Themselves

Customer Reviews

Real Reviews From Real Waterproofing Jobs

24/7 Emergency Waterproofing experts in Westchester, IL
★★★★★

"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, Westchester
★★★★★

"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, Westchester
★★★★★

"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, Westchester
★★★★★

"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, Westchester
★★★★★

"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, Westchester
★★★★★

"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, Westchester
FAQ

Straight Answers About Waterproofing

Response time depends on urgency — active flooding is treated as top priority, while non-urgent inspections are usually booked within the week.
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.
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.
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.
We document every job with photos and moisture readings you can submit for any claim, regardless of what your policy ultimately covers.
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.
Warranty terms are documented and registered to the property address, with a clear process for filing a service claim if anything comes up.
Coverage extends across Westchester — call +1-866-476-1348 to confirm your specific address, though it's almost certainly within our service area.
For the actual repair, it depends on scope — interior work often doesn't require you to be present for the full job, while we'll coordinate access details with you directly for anything involving excavation.
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.

Waterproofing Coverage in Westchester

Whether your property in Westchester has a finished basement, an unfinished crawl space, or a slab foundation, our crews carry the equipment and training to assess and quote all three foundation types on the same visit.
