Arrow Tight Waterproofing: Straight Answers, Real Fixes, in Darien
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 Darien is licensed, background-checked, and trained to diagnose before quoting β not the other way around.
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 Darien, residential or commercial.
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 GA 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 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 Darien.
01
Efflorescence on Basement Walls
We see this most often on walls that look completely dry to the touch β the salt deposit is evidence of past water movement, not current dampness.
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
The cove joint is the single most common water entry point in basements β 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 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
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
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
What Arrow Tight Waterproofing Handles in Darien
We don't sell a single fixed package β every property in Darien gets a scope built around what our inspection actually finds.
01
Emergency Water Intrusion Response
When water is actively entering a property in Darien, our first priority is stopping the intrusion, then extracting standing water before secondary damage sets in.
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 Darien, we install interior drain tile, sump systems, and crawl space encapsulation sized to your property's actual groundwater load β not a one-size package.
We size every residential system β pump horsepower, pipe diameter, gravel bed depth β to your specific property rather than a generic template.
Commercial foundations in Darien carry different risk than residential ones β larger footprints, tenant liability, and often tighter access β and our crews scope and schedule around that.
Commercial jobs get the same commercial-grade materials as our residential work β 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.
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.
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.
Battery backup and monitored alarm options are available on every pump we install, so a power outage during a storm doesn't leave the system unprotected.
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
Crews are staged regionally in Darien specifically to keep response times short β most inspections are scheduled within days, and emergencies get same-day priority.
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
Material selection isn't where we compete on price β we'd rather lose a bid than install something we know will fail in a few years.
Diagnosis Before Recommendation
Our technicians document the actual water path and pressure source before recommending a fix, so you're paying for the right repair the first time.

FAQ
What Darien, GA 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.
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 β 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.
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 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.
Yes β every completed system includes a written warranty that's transferable if you sell the property, not just a verbal assurance.
Coverage extends across Darien β 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 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 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.
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.

Waterproofing Coverage in Darien
