Steel Support Post
Steel Support Post Installation
The floor system of your home rests on a network of beams and posts that transfer the weight of everything above — your floors, walls, furniture, and family — down to the foundation below. When moisture damage, wood rot, or years of neglect weaken the wooden posts and beams supporting your floor system, the consequences show up as sagging floors, bouncing steps, uneven surfaces, and doors that no longer close properly. Left unaddressed, deteriorating support posts place dangerous stress on your entire floor structure and can lead to catastrophic failure over time. Atlanta Waterproofing installs heavy-duty adjustable steel support posts that permanently restore load-bearing strength to your compromised floor system — giving your home the solid, stable foundation it needs to stand strong for decades to come.
How Do Steel Support Posts Work?
Our certified technicians begin with a thorough inspection of your crawlspace or basement to identify every compromised support post and assess the extent of damage to the beams and floor system above. We then install heavy-duty adjustable steel support posts — also known as teleposts or lally columns — at precisely calculated positions beneath the weakened beams to restore proper load distribution and structural support. Each steel post is set on a solid concrete footing poured directly into the crawlspace or basement floor to ensure a stable, permanent base that will not shift or settle over time. Once installed, the posts are adjusted to the exact height needed to level the floor above and eliminate any remaining sag or unevenness. The result is a floor system that is stronger, more stable, and better supported than it was originally.
- Permanently restores load-bearing strength to weakened floor systems
- Adjustable steel construction allows precise leveling of sagging floors
- Set on solid concrete footings for a stable, permanent base that never shifts
- Eliminates bouncy, sagging & uneven floors throughout your home
Steel support post installation is almost always performed alongside other moisture control and structural repair work — because steel posts installed in a wet, unprotected crawlspace are only a partial solution. Moisture will continue to attack the surrounding wood structure unless the root cause of the water intrusion is also addressed. That is why every steel support post installation we perform is accompanied by a comprehensive assessment of your crawlspace moisture conditions and a recommendation for complete protection — ensuring your new support system stays in peak condition for the lifetime of your home.
Frequently Asked Questions
How do I know if my support posts need to be replaced?
The most common signs that your support posts are failing include floors that feel soft, spongy, or noticeably bouncy when you walk across them, visible sagging or dipping in certain areas of your floor, doors and windows on the floor above that suddenly stick or no longer align properly, creaking or cracking sounds coming from beneath your floors, and visibly deteriorated, rotted, or leaning wooden posts when inspecting your crawlspace. Any one of these signs warrants a professional inspection — and catching the problem early significantly reduces the scope and cost of the repair.
Why are steel posts better than wood posts?
Traditional wooden support posts are highly vulnerable to the moisture conditions commonly found in Atlanta crawlspaces. Even pressure-treated lumber absorbs moisture over time, leading to softening, rot, and eventual structural failure — often without any visible warning signs on the surface. Steel support posts are completely impervious to moisture damage, rot, and pest infestation. They do not warp, soften, or deteriorate over time. They are adjustable, allowing for precise leveling and future adjustments if needed. And they are engineered to carry significantly greater loads than comparable wooden posts — making them the superior long-term solution for any crawlspace or basement support application.
Will steel support posts fix my sagging floors completely?
In most cases, yes. Our adjustable steel support posts are installed and carefully raised to lift sagging beams and floor joists back toward their original level position — eliminating the sag and restoring a flat, stable floor surface above. However, the degree of correction achievable depends on the severity and duration of the sagging, the condition of the surrounding floor structure, and whether any additional repairs to damaged joists or beams are also needed. Our technicians will give you an honest assessment during your free inspection of exactly what level of correction is achievable in your specific situation — and we never overpromise results we cannot deliver.
