Arrow Tight Waterproofing: Straight Answers, Real Fixes, in Detroit
Arrow Tight Waterproofing exists because too many property owners in Detroit were getting patchwork fixes instead of real diagnosis. Our crews are licensed in MI, carry full liability coverage, and are trained to find the actual water path before recommending anything.
Whether the job is a single crack injection or a full drainage overhaul, the same certified crew handles it start to finish in Detroit β no subcontractors, no handoffs, no one new showing up halfway through.
Every technician completes ongoing training as materials and methods evolve β 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 MI with full liability and workers' comp coverage
Thermal imaging and calibrated moisture readings before every quote

Direct-employee crews β never subcontracted out
Warning Signs
What a Failing Foundation Actually Looks Like
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 Detroit.
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 β the pump working overtime today is the pump failing sooner than expected.
05
Bowing or Leaning Foundation Walls
Even a slight inward lean in a block wall signals lateral soil pressure building against the foundation β this needs structural evaluation, not just a sealant.
06
Rust Stains Bleeding Through Concrete
Rust streaks mean water has reached embedded rebar or metal lath and started oxidizing it β 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
Our Core Waterproofing Services in Detroit
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Detroit.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we β our emergency line in Detroit 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.
Residential waterproofing in Detroit covers everything from a single crack injection to a full-perimeter drainage retrofit, scoped after a real inspection.
Every residential install includes post-job moisture verification, so you have documented proof the system is working, not just our word for it.
For property managers in Detroit, 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.
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.
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.
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
Pricing surprises are the single biggest complaint we hear about competitors, so we built our proposal process specifically to eliminate them.
Fast Local Dispatch
Response time isn't an afterthought for us β it's a scheduling metric we track and staff around, not just a marketing line.
Satisfaction Backed in Writing
Every completed system comes with a written, transferable warranty β 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 β not hardware-store equivalents.
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.

What Customers Say About Arrow Tight Waterproofing
β β β β β
"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. β Homeowner, Detroit
β β β β β
"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. β Emergency Client, Detroit
β β β β β
"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. β Property Manager, Detroit
β β β β β
"Appreciated that they didn't just sell us a package. The inspection actually found the real problem β a bowing block wall β and the carbon fiber reinforcement plus crack injection fixed it properly instead of just sealing the surface.Would recommend them without hesitation."
M. β Homeowner, Detroit
β β β β β
"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 β no more constant cycling, and it's kept up with two heavy storms since.Exactly the level of service we expected."
D. β Homeowner, Detroit
β β β β β
"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."

FAQ
What Detroit, MI Customers Ask Us Most
Response time depends on urgency β active flooding is treated as top priority, while non-urgent inspections are usually booked within the week.
Yes β 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 β 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 β 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 β check your specific policy language.
Timeline depends entirely on scope β 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.
Warranty terms are documented and registered to the property address, with a clear process for filing a service claim if anything comes up.
We provide Waterproofing services in Detroit, with regionally staged crews that keep response times reasonable across the footprint we serve.
For the actual repair, it depends on scope β 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 β a caulked crack, a coat of sealant β 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.
