Decatur crawl spaces have the most severe structural conditions in metro Atlanta because the homes are the oldest and the crawl spaces have had zero moisture protection for their entire lifespan. The bungalows, Tudor revivals, and craftsman homes in Oakhurst, Winnona Park, Great Lakes, and the MAK District in the 30030, 30032, and 30033 zip codes were built from 1900 through the 1940s with structural systems that have been absorbing moisture for 80 to 120 years.
The original support systems in these homes used stacked fieldstone, hand-laid brick, or early unreinforced concrete piers sitting on shallow footings or bare soil. After a century of moisture exposure, the mortar has dissolved, the stones have shifted, the bricks have spalled, and many piers have lost the ability to carry their design load. Some piers we inspect are held together by nothing more than gravity and the weight of the house pressing down on them.
The girder beams spanning between these deteriorating piers were typically rough-sawn dimensional lumber. They develop rot at the bearing points where they rest on piers because moisture concentrates at these contact surfaces. Once rot penetrates the bearing surface, the beam shifts and drops, taking the floor joists and the floor above with it. The 2x8 or 2x10 floor joists are similarly affected, developing soft spots and mold throughout their length from decades of humidity exposure.
Decatur revitalization has added modern loads to these aging structures. New tile bathrooms, granite kitchen counters, hardwood floor refinishing, and second-story additions all increase the weight on a floor system that was designed for a much lighter 1920s home and has been weakened by a century of moisture. The crawl space that barely supported the original load now carries significantly more on compromised structure.
In Decatur bungalows with failed pier systems, floor slopes of 2 to 4 inches across a room are common. Furniture leans, objects roll, and walking across the room feels like walking on a tilted surface. This is repairable.
Joists weakened by a century of moisture damage lose their stiffness. Every footstep creates a visible bounce that travels across the room. China rattles in cabinets. Picture frames shift on walls. The structure has lost its rigidity.
When the floor drops but interior walls remain attached to the ceiling structure, gaps open at the bottom of the wall. You may see daylight under walls or feel drafts at the base of interior partitions.
If you can see the crawl space piers through the access opening and the mortar is missing, stones are loose, or bricks are crumbling, the pier has reached the end of its structural life and needs replacement.
When floors slope significantly, doors hang in frames that are no longer plumb. Gravity causes them to swing in the direction of the slope. This is a direct indicator of how far the floor has dropped from level.
If a contractor installing new tile, hardwood, or cabinets tells you the floor is too far out of level for their work, the crawl space needs structural repair before the renovation can proceed properly.
We remove every failed stacked stone, brick, and early concrete pier and replace them with adjustable steel piers on properly engineered concrete footings. The steel piers are precisely adjustable, corrosion-resistant, and rated for significantly more load than the original materials. For a typical Decatur bungalow, this means replacing 8 to 20 piers throughout the crawl space.
Original rough-sawn girders with rot at bearing points are sistered with new treated lumber or fully replaced depending on damage severity. For full replacement, we temporarily jack the floor above, remove the failed beam, install the new beam on new piers, and lower the floor onto the new support. We match the beam size to current load requirements, which often means a larger beam than the original to support renovation-added weight.
We evaluate every joist with a resistance probe to determine remaining strength. Joists that retain adequate capacity are left in place. Weakened joists are sistered with new treated lumber bolted alongside. Joists that have lost more than half their capacity are replaced entirely. All new wood receives borate treatment for long-term protection.
Decatur historic homes require careful floor leveling to avoid damaging plaster walls, original trim, and architectural details. We raise the floor in small increments over several hours, checking for stress at plaster joints and trim connections after each lift. The goal is level floors without sacrificing the historic character of the home. Most floors reach within a quarter inch of level.

Financing available through GreenSky. We recommend pairing structural repair with waterproofing or encapsulation to protect the new structure.
Crawl space repair in Decatur typically costs between $4,000 and $12,000. Historic homes with original stacked stone or brick pier systems require more extensive work than newer construction. Individual pier replacement runs $800 to $1,500 per pier. Full structural restoration of a 1920s bungalow crawl space ranges from $8,000 to $20,000.
Yes, and this is one of our most common Decatur projects. We remove the original stacked fieldstone or brick piers and replace them with adjustable steel piers on properly poured concrete footings. The steel piers provide precise height adjustment, significantly more load capacity, and resistance to the moisture conditions that destroyed the original stone piers.
No. While some settling in a 100-year-old home is expected, floors that slope more than half an inch across a room indicate repairable structural failure, not normal aging. We can restore most Decatur floors to within a quarter inch of level, which eliminates the rolling-ball and door-dragging problems that homeowners assume are permanent.
Before. Adding weight from a new kitchen with granite counters, a tile bathroom, or a second-story addition to a crawl space that is already failing structurally makes the problem worse. We recommend completing crawl space structural repair and waterproofing before any above-grade renovation that adds load to the floor system.
Our crews are experienced in tight crawl spaces common in Decatur bungalows. We use compact tools designed for confined work and can replace piers, sister joists, and install beams in spaces as low as 18 inches. If the space is too tight for the required work, we selectively excavate to gain clearance in the work area.
