The Arrow Tight Waterproofing Story — Built by Waterproofing Specialists, Not Salespeople
Arrow Tight Waterproofing exists because too many property owners in Denver were getting patchwork fixes instead of real diagnosis. Our crews are licensed in IN, carry full liability coverage, and are trained to find the actual water path before recommending anything.
We've built our reputation in Denver 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 Denver 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 IN 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 Denver.
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
Persistent musty odor almost always traces back to elevated humidity or an active leak feeding mold growth somewhere you can't see.
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
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
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
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
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.
Core Services
Complete Waterproofing Solutions, in Denver
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Denver.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we — our emergency line in Denver is answered live, 24 hours a day, with crews dispatched to stop the immediate entry point first.
We carry the equipment needed to control an active situation immediately, then scope the permanent fix once the emergency is under control.
For homeowners in Denver, 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 Denver 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.
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 Denver 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.
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
We don't run a single centralized dispatch queue; regional staging means the crew reaching you in Denver 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
A diagnosis-first approach costs us more time per estimate, but it's the reason our repeat-callback rate is a fraction of the industry average.
Our Process
From Your Call to a Documented Fix
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
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
Review the proposal at your own pace; we don't pressure same-visit sign-off, though we can often start within days once approved.
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.

"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, Denver
★★★★★
"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, Denver
★★★★★
"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, Denver
★★★★★
"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, Denver
★★★★★
"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.Exactly the level of service we expected."
D. — Homeowner, Denver
★★★★★
"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
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.
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.
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.
Always an in-person inspection — we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
Yes — every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
Coverage extends across Denver — 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 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.

Same-day or next-day scheduling is typically available for non-emergency inspections, with active flooding calls prioritized ahead of the standard queue.
Whether your property in Denver 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.
If you're unsure whether your address falls within our service footprint, the fastest way to find out is simply calling +1-866-476-1348 — dispatch can confirm coverage on the spot.
