Exterior membrane systems, footing drains, and corrected grading tackle Oxon Hill, MD water intrusion at the source, before it ever reaches the interior wall.
A lot of Oxon Hill, MD 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 Oxon Hill, MD exterior job.
Weather-dependent scheduling means we plan exterior jobs around Oxon Hill, MD's rainy season windows when possible.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.
Every Oxon Hill, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Oxon Hill, MD waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
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 Oxon Hill, MD water intrusion causes, and it's often the cheapest fix on this list.
We also inspect and reseal the window frame itself while the well is open.
This is often bundled with grading correction since the two issues usually show up together.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
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.

We'll walk through both options and their trade-offs so you can make an informed choice.
