The floor gets soft or sloped
Raised houses in Ardsley Park, the Victorian District and Isle of Hope sit on piers and sills over a crawl space. Wet joists, rot and termites are the usual reasons a floor sags. Crawl space problems
Chatham County and Richmond Hill
Savannah houses sit on wet sand, and the water decides what goes wrong
Most trouble under a coastal Georgia house comes from moisture, not from the swelling clay people blame in other states. Here is what that looks like in Savannah, Pooler, Richmond Hill, Tybee, Wilmington Island and Isle of Hope.

Three things that go wrong under a Savannah house
The slab cracks or the doors stick
Newer slab houses in Pooler and Richmond Hill crack and settle where water collects. Foundation problems
The old brick turns to powder
Savannah gray brick and tabby are soft, and the wrong patch makes them worse. Downtown owners also deal with a historic review. Permits

Why a Savannah house is not a Texas house
The Chatham County planning commission describes the county as Atlantic Coast flatwoods: nearly level ground, poorly drained, with soils mostly in the highest runoff group because the water table sits close to the surface. It names high groundwater and limited drainage as the main causes of inland flooding (Metropolitan Planning Commission, Natural Resources draft, read 2 November 2026).
That is a different problem from the shrink and swell cycle in clay country. Here the ground stays wet, the air is muggy for about half of the year, and a tropical storm can park ten inches on the city in two days, as Debby did in August 2024.
Before you hire anyone, ask five things
- What exactly is wrong, and what is the proof? Photos, level readings, a moisture reading.
- Is the cause water? If it is, fixing the water comes before anything else.
- Does the job need a permit, and who pulls it?
- Is the house in a historic district, a flood zone, or both?
- Does the company hold a Georgia contractor licence for this kind of structural work? You can look it up on the Secretary of State licence search.

Who answers when you call
Hostess City Foundation Repair is a local guide run by Marketing Doctor LLC. It does not do the work. The phone number and the request form go to one independent company that works in the Savannah area, and that company decides what it can do for you. Georgia law treats offering or bidding on structural work as contracting, so nothing on this site is an offer or a price for your house.
Short answers
Is Savannah soil the same as Atlanta clay?
No. The county sits on coastal flatwoods that are poorly drained, with a shallow water table, according to the county planning commission. Moisture, not clay swelling, drives most of the trouble.
Do I need a permit to repair a foundation?
Often yes, and the office depends on the address. Savannah, Pooler, Richmond Hill, Tybee and unincorporated Chatham County each run their own. Start with the permit guide.
Does a flood zone change anything?
Yes. Tybee and Savannah both apply a substantial improvement rule in flood zones, so a large repair can trigger extra review. Details are on the Tybee page.
