Exterior membrane systems, footing drains, and corrected grading tackle White Marsh, MD water intrusion at the source, before it ever reaches the interior wall.
A lot of White Marsh, 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 White Marsh, MD exterior job.
Weather-dependent scheduling means we plan exterior jobs around White Marsh, 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 White Marsh, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive White Marsh, MD waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
Soil that slopes toward the foundation instead of away from it is one of the most common White Marsh, 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.
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.
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.

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