Exterior membrane systems, footing drains, and corrected grading tackle Marriottsville, MD water intrusion at the source, before it ever reaches the interior wall.
A lot of Marriottsville, 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 Marriottsville, MD exterior job.
Weather-dependent scheduling means we plan exterior jobs around Marriottsville, 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.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
Every Marriottsville, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
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 Marriottsville, 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.
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.

"Fast turnaround given how much digging was involved."

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 measure your specific foundation during the on-site inspection rather than assuming a standard depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
We'll recommend starting there if the inspection suggests surface water is the primary cause.
