Exterior membrane systems, footing drains, and corrected grading tackle Royal Oak, MI water intrusion at the source, before it ever reaches the interior wall.
Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Weather-dependent scheduling means we plan exterior jobs around Royal Oak, MI's rainy season windows when possible.
Landscaping restoration is included in the scope, not billed as a separate surprise line item.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.
Every Royal Oak, MI Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Royal Oak, MI 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.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
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.

— Royal Oak Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."

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.
