Yard Drainage & Foundation Waterproofing in Mobile, AL
Almost every foundation problem we repair in Mobile traces back to water: a yard that holds it, a roof that dumps it at the foundation, a lot graded toward the house instead of away. Fixing the structure without fixing the water is a repair with an expiration date — which is why drainage is a core service for us, not an afterthought.
We design and install the unglamorous systems that keep soil stable: French drains that intercept and carry water away, surface drains and catch basins for standing-water spots, downspout piping that discharges rain far from the foundation, and regrading that restores the slope a lot was supposed to have. Done right, they're invisible — the yard just stops being a swamp.

How it works
Walk us through the water
Where it stands, where it flows, what it does in a hard rain — you know your lot; that's the map.
Assess after-rain if possible
We look at slopes, soil, downspouts, and where the water actually wants to go.
System design and price
A drawn plan — drains, basins, discharge points — with one written price.
Install and restore
Trenches dug, pipe and gravel placed correctly, sod and beds put back the way we found them.
Five and a half feet of rain needs somewhere to go
Mobile gets more annual rainfall than almost any other city in the country, much of it in violent summer downpours that drop inches in an hour. Flat lots in older neighborhoods and heavy subsoils that drain slowly mean that water sits — against foundations, under crawl spaces, in low back corners of the yard.
That standing water is the engine behind the rest of our work: it softens the soil foundations settle into, feeds the humidity that rots crawl spaces, and washes out the ground under slabs. A well-placed French drain or a regraded side yard is genuinely the cheapest foundation repair we sell — it just happens before the damage instead of after.
Drainage & Waterproofing questions
How much does a French drain cost in Mobile?
Typical residential French drain runs land between $2,000 and $6,000 depending on length, depth, and discharge distance. Simple downspout extensions and small surface-drain fixes can be a few hundred dollars. The assessment and written quote are free.
Will a French drain fix water in my crawl space?
If the water is coming from surface runoff or roof water, usually yes — intercepting it outside is the right fix. If the water table itself rises into the space during wet months, the answer is drainage inside the crawl space with a sump. The inspection tells us which one you have.
My yard floods every summer storm. Where do we start?
Start with where the water should end up — street, storm drain, or a low discharge point. We design backward from there. Nine times out of ten the fix combines downspout piping with one properly placed drain line, not a yard-wide excavation.
