From emergency extraction to permanent drain tile systems, we diagnose the real problem before recommending a fix.

Arrow Tight Waterproofing has spent years earning a reputation in Glenelg for showing up when a basement is taking on water and not leaving until it's actually fixed.
Our field teams hold real Waterproofing credentials and are licensed in MD, with training that covers moisture mapping, sump system design, and foundation crack evaluation in depth.
A basement filling with water doesn't wait for a convenient appointment, so our dispatch model is built around same-day response for active seepage in Glenelg.
Transparency doesn't end once the quote is signed — we walk you through what was actually done once the crew finishes, not just what was proposed at the start.
Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.
That persistent musty odor downstairs almost always traces back to trapped moisture somewhere in the wall or floor assembly.
Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.
A door frame that's suddenly out of square, or a window that won't close flush, can point to foundation movement.
Stair-step cracking in a block wall usually signals something more than simple concrete shrinkage.
Puddling near the same wall section after every storm points to a specific, fixable entry point.
An overworked sump pump is a warning sign in itself — it's compensating for something upstream.
Hold a level against your foundation wall — even a small deviation from plumb is worth having evaluated.
If your basement dehumidifier is running around the clock and humidity still creeps up, the moisture source needs addressing, not just managing.
Unexplained rust forming on tools or ductwork is often the first physical evidence of chronically elevated humidity.
We don't push a single product — every job starts with a diagnosis, then a recommendation matched to what's actually happening at your property.
Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. Extraction is never treated as the finish line — it's the first step toward a lasting repair.
A perimeter drain tile channel installed below the slab intercepts groundwater before it can reach your floor, routing it to a properly sized sump basin and pump. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.
We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. Photos and measurements are logged before and after every injection for your records.
Where the source is grading, a failed footing drain, or membrane failure visible from outside, exterior excavation and a rubberized membrane address the problem at its origin.
A sealed, encapsulated crawl space with a reinforced vapor barrier cuts off the ground moisture that feeds humidity, mold, and wood rot before it ever reaches your living space.
We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Cellular notification add-ons alert your phone directly if the system is ever triggered.
Dimple-board membrane installed against a foundation wall creates an air gap that channels incidental moisture down to a collection point instead of letting it wick into finished drywall. We explain the engineering rationale before recommending any wall reinforcement work.
Five things that actually separate a specialized Waterproofing crew from a general contractor with a truck and a sump pump on hand.
A lot of companies claim to offer Waterproofing, but the difference shows up in how the job is actually diagnosed and executed — not in the advertising.
A basement actively taking on water moves to the front of the schedule — most Glenelg, MD service areas see a technician within hours, not days.
Pricing is based on what our diagnostic actually finds, not a generic per-square-foot estimate pulled out of thin air.
Technicians are trained to identify the real entry point, not just treat the most visible symptom.
Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.
Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.
Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.
One call connects you to local dispatch, not a national call center — they'll ask a few questions to understand what you're seeing and prioritize accordingly.
You'll see exactly what the equipment finds — this isn't a sales walkthrough, it's a real inspection.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
A written warranty and, where relevant, a post-storm follow-up check come standard with every completed installation.
What homeowners in Glenelg, MD are saying after calling us for Waterproofing.
"Had standing water after a spring storm and they had a full drain tile system installed within the week. Completely dry since."
"They showed us the actual crack on camera before recommending anything — nobody had ever bothered to look that closely before."
"Quote matched the final invoice to the dollar. No surprise line items once they opened up the wall."
"Battery backup pump they installed kept us dry through a multi-hour outage last winter. Would've flooded otherwise."
"Appreciated that they told us plainly our crack needed an engineer's eyes before injecting anything — didn't just upsell us."
"Crawl space encapsulation got rid of a musty smell we'd been dealing with for two years. Should've called sooner."
"They walked us through the moisture readings on the spot instead of just telling us to trust them. Made the whole decision easier."
"Sump pump replacement was done same-day after our old one failed during a storm. Genuinely impressed with the response time."
"We got three other quotes before calling them, and theirs was the only one that actually explained why our specific wall was leaking."
"Vapor barrier install in our crawl space was clean, fast, and the humidity reading dropped noticeably within a couple weeks."
