Interior drainage, exterior grading, crack injection, or a combination — we scope what your Jericho, NY basement actually needs.

We've walked into plenty of Jericho, NY basements where two or three prior repairs each addressed a different symptom without solving the underlying combination of causes. Diagnosing the full picture first is what actually breaks that cycle.
A wet basement is often caused by more than one contributing factor, and we address the combination, not just the obvious symptom.
Our technicians know the common wet-basement patterns specific to Jericho, NY construction styles and soil conditions.
We break down each component of the fix so you understand what you're paying for and why it's included.
Between drain tile, sump systems, crack injection, and exterior grading, we can address nearly any wet basement cause without bringing in a second contractor.

Every Jericho, NY Wet Basement Repair job starts with an inspection, not a generic package — here's what that typically includes.
A written diagnostic summary explains what we found and why we're recommending a specific repair combination.
When groundwater is the primary source, interior drain tile tied to a properly sized sump basin intercepts it before it reaches your floor.
Active wall cracks get epoxy or polyurethane injection as part of a comprehensive wet basement repair, sealed and classified before we move to other work.
We correct grading and extend downspouts as part of the full repair scope where the inspection points that direction.
We coordinate with mold remediation specialists when visible growth is already present, since that's outside our own scope.

We ask how long the basement has been wet, whether it's constant or storm-related, and what you've already tried.
A technician checks interior walls and floor, exterior grading, gutters, and window wells to build a complete picture of what's driving the moisture.
We explain the reasoning behind each recommendation so the plan makes sense, not just a list of line items.
We're available to reassess if conditions change after a major storm, since Jericho, NY weather can be unpredictable.

— Jericho Homeowner
"Musty smell that had bothered us for two years is finally gone after the full repair."
— Jericho Customer
"Basement had flooded twice before we called. Combination of drain tile and grading correction has kept it dry through two storm seasons now."
— Jericho Homeowner
"Didn't try to sell us the most expensive fix — recommended grading correction first since that was the actual primary cause."
— Jericho Customer
We review prior repair work as part of the inspection to identify what may have been missed.
We check interior walls and floor, exterior grading, gutters, downspouts, and window wells using moisture meters and visual inspection.
Addressing only one factor while ignoring the others is a common reason prior repairs fail.
Getting humidity and water intrusion under control is a necessary first step before mold remediation can hold long-term.
Cost depends entirely on which combination of repairs your basement needs — we won't estimate a number until the diagnostic inspection is complete.
We give you a realistic timeline in the written repair plan based on your specific diagnosis.
