We excavate only where necessary and restore landscaping as part of the scope.
A lot of Ronkonkoma, 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 Ronkonkoma, NY exterior job.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
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.
Soil that slopes toward the foundation instead of away from it is one of the most common Ronkonkoma, NY water intrusion causes, and it's often the cheapest fix on this list.
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.
We flag any utility lines or landscaping features that need special handling during excavation.
We explain what's included in landscaping restoration so there's no confusion after backfill.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

We'll recommend the right approach based on what the inspection actually finds.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Ronkonkoma, NY water intrusion issues on their own.
