A properly installed interior perimeter drain system intercepts groundwater at the slab edge and routes it to a sump basin before it ever reaches your floor.
Drain tile that isn't sloped correctly is one of the most common installation failures we see when repairing someone else's prior work — water simply pools instead of flowing to the basin. We verify slope with a level, not by eye.
We're licensed and insured for residential and light commercial interior drainage work across McLean, VA.
Most McLean, VA inspection requests get a response within a day or two.
Sump basin and pump costs are itemized separately so you can see exactly what makes up the total.
Drain tile that isn't sloped correctly simply won't move water — we verify slope with a level during installation, not just by eye.
Every McLean, VA Interior Drainage System job starts with an inspection, not a generic package — here's what that typically includes.
A channel is cut along the slab edge, perforated pipe is laid with proper slope, and gravel backfill allows water to flow freely into the drain.
Every interior drain system needs a sump basin as its endpoint — we size the basin and pump to match the drain tile's expected inflow.
For finished basements where cutting the slab isn't practical, a baseboard channel system captures wall seepage without disturbing existing flooring.
The cove joint where wall meets floor is sealed and tied directly into the drain system so water is captured right at the entry point.
We camera-inspect old systems where accessible to determine whether repair or replacement makes more financial sense.
This helps us bring the right materials and estimate linear footage before the visit.
We also check existing drainage, if any, to determine whether repair or new installation makes more sense.
You'll see drain tile footage, basin specs, and any cove joint work broken out in the written estimate.
Most residential interior drainage installs finish in one to three days depending on perimeter length.
"Water was coming in along one wall every heavy rain. They installed targeted drain tile just on that section instead of charging us for the whole perimeter."
— McLean Homeowner
"Finished basement meant we couldn't cut the slab easily. Baseboard channel system worked great as an alternative."
— McLean Customer
"Explained the slope requirements in a way that actually made sense, not just technical jargon."
— McLean Homeowner
"Sump basin placement was smarter than what a previous contractor had proposed — shorter discharge run, less noise."
— McLean Customer
Not always — if water is only entering along one wall, a targeted section can be enough, which we determine from inspection findings.
We'll recommend whichever fits your basement's finish level and budget.
{Sometimes — if the pipe itself is intact but clogged with silt, cleaning can restore function without a full re-installation.|We camera-inspect where accessible to make that determination before recommending replacement.}
Basin size is based on expected water inflow from the drain tile's linear footage and your McLean, VA area's typical rainfall intensity.
If disruption is a major concern, we can discuss the baseboard channel alternative instead.
We give you a realistic timeline in the written quote based on your specific basement layout.
