Exterior membrane systems, footing drains, and corrected grading tackle Medford, NY water intrusion at the source, before it ever reaches the interior wall.

A lot of Medford, NY exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
We call in utility locates before any digging starts, standard on every Medford, NY exterior job.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Landscaping restoration is included in the scope, not billed as a separate surprise line item.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.

We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.

Photos of the exterior foundation area help us plan equipment and access before the visit.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."
— Medford Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Medford Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— Medford Homeowner
"Fast turnaround given how much digging was involved."

Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.
We discuss landscaping impact during the estimate so there are no surprises.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Medford, NY water intrusion issues on their own.
Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
