The Arrow Tight Waterproofing Story β 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 Lancaster is licensed, background-checked, and trained to diagnose before quoting β 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 Lancaster β no subcontractors, no handoffs, no one new showing up halfway through.
We keep detailed job records for every property in Lancaster 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 SC 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
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 Lancaster.
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
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
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
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
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
What Arrow Tight Waterproofing Handles in Lancaster
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Lancaster.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we β our emergency line in Lancaster 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.
Residential waterproofing in Lancaster covers everything from a single crack injection to a full-perimeter drainage retrofit, scoped after a real inspection.
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 Lancaster carry different risk than residential ones β larger footprints, tenant liability, and often tighter access β 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.
Beyond drainage, our crews handle foundation crack injection, carbon fiber wall reinforcement, and structural crack classification for properties in Lancaster 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.
These aren't marketing lines β 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 Lancaster 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
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
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.

How a Waterproofing Job Works With Us
01

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 β materials, labor, and scope laid out in writing, not estimated verbally.
04
Installation & Warranty Documentation

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.That's the kind of fix that actually holds up."
R. β Homeowner, Lancaster
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.That's the kind of fix that actually holds up."
K. β Emergency Client, Lancaster

"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. β Property Manager, Lancaster

"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.That's the kind of fix that actually holds up."
M. β Homeowner, Lancaster

"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."

"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
Straight Answers About Waterproofing
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.
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.
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.
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.
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 Lancaster, 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 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.
