Arrow Tight Waterproofing: Straight Answers, Real Fixes, in Dearborn
Too many contractors in Dearborn 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 Dearborn, residential or commercial.
We keep detailed job records for every property in Dearborn 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 MI 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 Dearborn property Needs Attention Now
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 Dearborn.
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
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
Continuous cycling means your pump is handling more groundwater than it was sized for, and it's only a matter of time before it fails under the load.
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
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 Dearborn
We don't sell a single fixed package — every property in Dearborn gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
When water is actively entering a property in Dearborn, 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.
Residential waterproofing in Dearborn covers everything from a single crack injection to a full-perimeter drainage retrofit, scoped after a real inspection.
We size every residential system — pump horsepower, pipe diameter, gravel bed depth — to your specific property rather than a generic template.
For property managers in Dearborn, 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.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Dearborn showing signs of settlement or lateral pressure.
Every structural repair is documented with before-and-after photos and moisture readings as part of your warranty file.
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.
The Arrow Tight Waterproofing Standard, in Dearborn
These aren't marketing lines — they're the specific practices that separate a repair that lasts from one that doesn't.
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 Dearborn isn't driving hours to get there.
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
How a Waterproofing Job Works With Us
01
Call or Request an Inspection
Call +1-866-476-1348 and describe the issue. We route the right technician for your specific situation rather than a generalist.
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
You receive an itemized proposal before any work begins — materials, labor, and scope laid out in writing, not estimated verbally.
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.

"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, Dearborn
★★★★★
"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, Dearborn
★★★★★
"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, Dearborn
★★★★★
"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, Dearborn
★★★★★
"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, Dearborn
★★★★★
"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."

FAQ
Waterproofing Frequently Asked Questions
Response time depends on urgency — active flooding is treated as top priority, while non-urgent inspections are usually booked within the week.
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.
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.
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 Dearborn, with regionally staged crews that keep response times reasonable across the footprint we serve.
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 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.
Service Area
Waterproofing Coverage in Dearborn
We built our coverage in Dearborn around regional crew staging rather than one central office, which keeps dispatch times shorter across the footprint we serve.
Call +1-866-476-1348 to confirm coverage for your specific address — given our regional staging in Dearborn, it's very likely within our service area.
Whether your property in Dearborn 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.
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.
