Interior Perimeter Drains
An interior drain is one of several ways to manage water near a basement, and rarely the first to try. Soil graded away from the walls sheds rain, and downspouts aimed away from the house and the neighbors are an early homeowner fix. An exterior footing drain, perforated pipe in gravel beside the footing, carries groundwater off but means digging; a French drain is a shallower stone trench that catches yard runoff.
Inside, an interior perimeter drain is perforated pipe in a stone-filled trench along the base of the walls, under a strip of new concrete. It slopes whatever seeps in to a sump pit, whose pump sends it onto the ground outdoors, clear of the foundation and neighboring land, never to a floor drain or the sanitary sewer. Joining any drain to a sewer is plumbing for a Georgia-licensed plumber with a permit.
Across the Georgia Piedmont, red clay subsoil is common, and because it lets water through slowly, soil against a wall can stay soaked long after rain. Ridges and creek valleys put many houses into slopes, with an uphill wall holding back damp ground. As Hurricane Helene came through, the National Weather Service logged 4.32 inches in Atlanta, GA on September 26, 2024, a record for the date.
In Druid Hills, Candler-McAfee and Avondale Estates, GA, DeKalb County maintains its drainage pipes, culverts and catch basins, plus a stretch of ditch about ten feet long past each pipe outlet, and leaves the rest of a creek or drainage easement to the owner; drainage questions go to 770-270-6243. Unincorporated DeKalb requires a specialty permit for any retaining wall of four feet or more standing apart from the foundation; Avondale Estates, GA requires a separate trade permit for drainage work regardless of value.
The Usual Scenarios
- Overflowing gutters. Packed gutters spill rain at the base of the wall; clearing them is a homeowner chore.
- Sunken backfill. Soil around a newer home can settle until the yard tilts toward the walls.
- Flooded window wells. A well with no working drain holds water against the glass.
- Tile that goes nowhere. Drain tile clogged with silt, or never tied to a working pump, leaves water at the footing.
The Typical Job, in Order
Once a contractor gets in touch, drainage work often moves in this order:
- A visit, then an estimate. The contractor sets up its own visit, walks the yard and basement, and lists the walls, feet of drain, pit and pump, and where water leaves the lot.
- Permits and reviews. These depend on scope and address, so the contractor checks first: the Office of Buildings, (404) 330-6150, handles City of Atlanta addresses, and DeKalb or the town handles the rest. Outside digging on a historic-district lot may need review, and plumbing waits for a licensed plumber.
- Trench and test. Pipe goes on gravel in a trench sloping to the pit, concrete closes it, and a hose shows water reaching the outlet.
Budgeting for Basement Drainage
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
Fixr's national 2026 numbers fill this table; no Atlanta, GA or Georgia price list was read. Interior drain is charged by the linear foot, so tiling one wet wall costs far less than a full loop. Backwater valves and sewer work are priced by a licensed plumber. The cost calculator and the cost guide go further.
Why One Contact Is Enough
With one request, a single independent contractor gets in touch rather than several unknown callers, and its estimate is its alone; this site prices nothing and hands out no inspections, discounts or gifts. The site exists to refer and advertise; it isn't a contractor, plumber or electrician and holds no residential or general contractor license and no plumbing license. Contractors may pay it a flat advertising fee, currently a free trial, tied to no job.
Nothing stops you from asking other contractors yourself. Check which Georgia license, if any, the work calls for, plus the business license and insurance certificates, and pay in stages.
Frequently Asked Questions
Should gutters and grading come before a drain system?
Often, yes. Clear gutters, extended downspouts and soil sloping away from the walls cost far less than cutting the floor; on a sloped lot, start uphill. If water still shows at the base of a wall after a long rain, ask a contractor about interior drain tile and a pit.
Who handles water coming up a floor drain?
The sewer owner, since that is a backup. East Point, GA residents report it to Water & Sewer, (404) 474-3834, or after hours at (404) 240-2183; Hapeville, GA residents start with City Hall, 404-669-2100; DeKalb's 770-270-6243 covers the three DeKalb places; City of Atlanta addresses use ATL311, 404-546-0311. Backwater valves and work on the house's own pipe belong to a Georgia-licensed plumber with a permit.
