Exterior membrane systems, footing drains, and corrected grading tackle McLean, VA 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 McLean, VA'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.
We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
This is the most comprehensive McLean, VA 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.
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.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.
"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."
— McLean Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— McLean Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— McLean Homeowner
"Fast turnaround given how much digging was involved."
— McLean Customer
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.
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.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of McLean, VA water intrusion issues on their own.
A typical residential wall section with membrane and footing drain work takes a few days depending on access and weather conditions.
