Arrow Tight Waterproofing has spent years earning a reputation in Port Jefferson Station for showing up when a basement is taking on water and not leaving until it's actually fixed.
Licensing here isn't a formality — every crew member is licensed in NY and specifically trained in the below-grade water intrusion work that Waterproofing actually requires.
We run a dispatch-first model: local crews stocked with diagnostic gear and repair materials, ready to move on active water intrusion the same day it's reported.
We believe a homeowner should be able to see the evidence behind a recommendation, not just take our word for it — every diagnostic visit comes with documented findings you can keep.
Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.
If the basement smell comes back within days of airing it out, that's moisture, not just staleness.
Chalky white streaks on your foundation wall are a visible sign that water has been passing through the concrete itself.
Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.
Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.
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.
A wall that bows inward even slightly is responding to soil pressure that isn't going away on its own.
Rising humidity readings in the basement that a dehumidifier can't keep up with.
Rust or corrosion on metal fixtures, HVAC components, or stored tools in the basement.
From emergency response to permanent structural fixes, here's the full range of work our crews handle in Port Jefferson Station.
Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.
This is the most common permanent fix for hydrostatic pressure seepage — proven, code-recognized, and installed without exterior excavation. 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.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
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. Backup systems activate automatically the instant the primary loses power or falls behind.
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 Port Jefferson Station, NY service areas see a technician within hours, not days.
Every quote breaks out material, labor, and equipment separately, delivered in writing before any drilling or coring begins.
A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.
Certification covers the specific systems we install — drain tile, sump basins, exterior membranes — not general construction knowledge alone.
Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.
No mystery about what happens after you pick up the phone — here's the exact sequence from first call to a finished, fully tested repair, start to end.
Describe the issue — a damp wall, standing water, a musty smell — and dispatch routes the right crew with matching equipment.
The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.
Once you approve the scope, installation is scheduled — often within days, faster for active emergencies.
Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.
Feedback from real Waterproofing customers across Port Jefferson Station, NY.
"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."
