Marietta has a diverse range of crawl space structural challenges because of the variety in housing age and terrain. The homes near the Marietta Square and along Church Street, Whitlock Avenue, and the Kennesaw Avenue corridor were built from the late 1800s through the 1960s with original pier-and-beam foundations using stacked fieldstone, hand-laid brick, or early concrete block piers. These original supports have been deteriorating for 60 to 130 years.
East Cobb neighborhoods like Walton, Indian Hills, Sope Creek, and Timber Ridge in the 30062, 30066, and 30067 zip codes were built in the 1970s and 1980s on slopes that create crawl spaces with dramatically variable heights. The uphill side may have only 18 inches of clearance while the downhill side has 4 feet. The uphill side — where moisture concentrates — is also the hardest to access for repairs, which means damage progresses unchecked for years in the areas that need attention most.
West Cobb homes near Kennesaw Mountain and along Due West Road face rocky soil that creates uneven pier support. Original footings placed on soil pockets between rock outcroppings settle as the soil compacts while footings on rock stay put. This differential settling causes one section of the floor to drop while the adjacent section remains level, creating the sloping floors and sticking doors that Cobb County homeowners know well.
The 30060, 30062, 30064, 30066, and 30067 zip codes all have significant crawl space structural repair needs driven by age, moisture, and terrain factors that are specific to Cobb County geography.
In pre-1970 Marietta homes, floor slopes of 1 to 3 inches across a room are common when original piers have failed. Homeowners often assume this is normal for old houses, but it indicates repairable structural failure.
In hillside homes, the uphill crawl space section stays wetter and the joists deteriorate faster. If the floors bounce or feel soft specifically on the uphill side of your home, moisture has weakened the structure in that area.
If you can see the crawl space piers and the mortar is missing, the stones are shifting, or the bricks are crumbling, the pier has lost structural integrity. These original piers need complete replacement with modern steel piers.
When the crawl space support system fails on one side, the main structure can pull away from the chimney, which sits on its own footing. A visible gap between the chimney and the house wall indicates significant differential settling.
Hold a level against your door frames. If they lean noticeably in one direction, the floor system beneath has shifted. This is especially common in Marietta split-level homes where the crawl space section settles independently from the slab section.
Stair-step cracks in exterior brick that start at or near the foundation level indicate the floor system is pulling away from the foundation wall as piers settle. The rigid brick cannot flex with the movement.
For pre-1970 Marietta homes, we remove failed fieldstone, brick, and early concrete piers and replace them with adjustable steel piers on engineered concrete footings. The steel piers are set to the precise height needed to re-level the floor system. We re-level incrementally over several hours to avoid stressing the old framing connections. This is specialized work that requires understanding how original homes were built.
Low-clearance crawl spaces on Marietta hillsides require specialized techniques. Our crews work in spaces as low as 18 inches using compact tools designed for confined work. We can sister joists, replace piers, and install beams in areas that larger contractors refuse to enter. If the crawl space is too tight for standard work, we excavate to increase clearance before making structural repairs.
Many Marietta homes were built with pier spacing that met code at the time but is wider than current standards recommend. We add supplemental piers between the original locations to reduce the span each girder carries. This is especially important in homes that have had heavy renovations — tile bathrooms, granite kitchens, second-story additions — that increase the floor load beyond what the original system was designed to carry.
Every piece of structural wood we install or repair receives borate preservative treatment. Borate penetrates the wood and provides long-term protection against both rot and wood-destroying insects. Existing wood that is sound but untreated also receives borate application to extend its service life in the now-drier environment.

Crawl space repair in Marietta typically costs between $3,000 and $10,000. Older pier-and-beam homes near the Marietta Square require more extensive work than newer construction due to the age and deterioration of original materials. Pier replacement runs $600 to $1,500 per pier. Full structural restoration of a historic pier-and-beam system ranges from $5,000 to $15,000.
Yes. We specialize in the pier-and-beam systems found in Marietta homes built before 1970. We replace deteriorated stacked stone or brick piers with modern adjustable steel piers, repair or replace failed girders, sister weakened joists, and re-level the entire floor system. The result is a modern support system beneath the original home.
Homes on Cobb County slopes experience uneven moisture distribution — the uphill side stays wetter than the downhill side. This means the structural wood on the uphill side deteriorates faster. Additionally, hillside crawl spaces have variable heights that create access challenges and allow moisture to concentrate in the lowest sections.
Yes. Bouncy floors are caused by weakened or undersized joists that flex under foot traffic. We sister damaged joists with new treated lumber, replace failed piers to restore proper support points, and add supplemental piers where the original spacing was too wide. The floor becomes rigid and solid after repair.
It depends on the extent of damage. We evaluate every structural member during inspection. Wood that still has 80% or more of its original strength gets sistered. Wood that has lost more than 50% of its strength gets replaced. Piers that have settled more than half an inch get replaced with adjustable steel piers. We only replace what needs replacing.
