Foundation drainage
Foundation drainage is the outside work that keeps rainwater from ever reaching your footing — perimeter drains, buried downspout lines, and grading that sends runoff away from the house instead of into the soil beside it.

Trusted foundation drainage across the Triangle
Foundation drainage is the outside work that keeps rainwater from ever reaching your footing — perimeter drains, buried downspout lines, and grading that sends runoff away from the house instead of into the soil beside it. Cary Sprinklers designs and installs these systems across the Triangle, and owner Adam K stands behind every job, not just the estimate. Most projects are dug, piped, and cleaned up in one to two days.
Triangle clay makes this a local problem with a local fix. Our clay sheds water fast on the surface, then holds it like a sponge once it soaks in, so the ground against your foundation can stay wet for a week after a Saturday storm. That saturated soil builds hydrostatic pressure that pushes on foundation walls and drives humidity up into the crawlspace. Foundation drainage done from the exterior relieves that pressure at its source, which beats running a dehumidifier against a wall that never dries out.
We handle foundation drainage for homeowners in Cary, Raleigh, Apex, Morrisville, Holly Springs, Fuquay-Varina and throughout Wake County — part of our drainage & french drains service.
Foundation drainage problems we solve
Diagnosed right and fixed with genuine Hunter, Rain Bird & Toro parts.
Standing water after rain
Puddles that sit against the house for days are soaking straight down along your foundation walls. A perimeter foundation drainage system collects that water and moves it to a safe discharge point before it settles in.
Musty crawlspace air
That damp smell under the house usually starts with wet soil outside, not a plumbing leak. Cut off the water at the perimeter and the crawlspace humidity drops with it.
Downspouts dumping at the base
A single roof valley can shed hundreds of gallons in one storm, and most builder splash blocks drop it two feet from the wall. We bury solid downspout lines that carry roof runoff well away from the house.
Yard sloped toward the house
When the grade tilts back at the foundation, every rain becomes a delivery. Corrective grading and surface drains with catch basins intercept the flow and redirect it.
Stains and soft soil at the wall
Water stains at the exterior base and muddy soil you sink into along the foundation are early warnings, not cosmetic issues. We trace where the water comes from and fix the route, not the symptom.
Irrigation soaking the beds
Sometimes the culprit is your own system — a stuck valve, a leaking lateral, or spray heads throwing water at the wall every morning. Because we service irrigation too, we check zones, nozzles, and precip rates as part of the diagnosis.
Signs you need foundation drainage
- Puddles that linger near the house after storms
- Musty or humid crawlspace

How the work happens, step by step
No mystery, no runaround — here’s the order we work in.
Walk the water
We start where the water starts — roofline, grade, soil, and irrigation coverage. No guesswork; we find the actual path water takes to your foundation, and we rule out a controller schedule or broken head over-watering the beds.
Design the fix and price it upfront
You get a specific plan: perimeter French drain, buried downspout lines, catch basins, grading, or some combination, with a written price before any digging. Free estimate, no invented add-ons later.
Install with controlled excavation
We trench only where the plan calls for it and protect the landscaping you have paid years to grow. Pipe gets proper slope, gravel, and fabric so the system keeps flowing in clay soil.
Test, bury, and restore
We run water through every line, confirm the discharge point works, then backfill and rake out. Most foundation drainage installs finish in one to two days, backed by a 12 month workmanship warranty.

Foundation drainage FAQ
How much does foundation drainage cost?
It depends on the length of the run, the depth, and whether we are grading or just piping, so we do not quote blind. We come out, walk the property, and give you a free written estimate with upfront pricing. The number we quote is the number you pay.
Do I need interior waterproofing or exterior foundation drainage?
Interior systems manage water after it has already reached your foundation; exterior work stops it from getting there. In most Triangle homes, fixing grading, downspouts, and perimeter drainage solves the cause. We recommend the repair before the bigger project whenever the repair will actually do the job.
How long does the work take?
Most foundation drainage projects take one to two days from first trench to final rake. Larger properties or jobs with significant regrading can run longer, and we tell you that before we start, not after.
Will my yard be torn up?
No more than the fix requires. We plan trench routes around root zones and irrigation lines, cut sod cleanly so it can go back down, and leave the discharge point tidy. Controlled excavation is one of the reasons people call us instead of a general excavator.
