Arrow Tight Waterproofing diagnoses the real cause before quoting anything β thermal imaging, moisture readings, and a written fixed price in Annapolis.
The Arrow Tight Waterproofing Story β Built by Waterproofing Specialists, Not Salespeople
Arrow Tight Waterproofing exists because too many property owners in Annapolis were getting patchwork fixes instead of real diagnosis. Our crews are licensed in MD, carry full liability coverage, and are trained to find the actual water path before recommending anything.
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 Annapolis, residential or commercial.
We keep detailed job records for every property in Annapolis 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 MD 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
How to Tell If your Annapolis property Needs Attention Now
Most foundation failures don't start as floods β they start small, and they're easy to miss until the damage compounds. Here's what our technicians look for on every inspection in Annapolis.
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
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
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
Paint and drywall absorb moisture vapor before liquid water ever becomes visible, so bubbling or soft spots near the baseboard are an early-stage signal, not a late one.
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 Annapolis
From emergency response to full commercial systems, here's the range of Waterproofing work our crews handle in Annapolis.
01
Emergency Water Intrusion Response
Active flooding doesn't wait for business hours, and neither do we β our emergency line in Annapolis 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.
For homeowners in Annapolis, 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.
For property managers in Annapolis, 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 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.
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.
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.
Why Property Owners in Annapolis Choose Arrow Tight Waterproofing
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
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
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 β never a downgraded consumer-grade substitute.
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.

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."

FAQ
What Annapolis, MD Customers Ask Us Most
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.
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.
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.
Always an in-person inspection β we don't quote sight-unseen, because an accurate scope requires actually seeing the moisture pattern and access conditions.
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 Annapolis 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 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.
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.
