Floor Supports

Frequently asked questions

What problems do floor supports fix?
Floor supports correct a wide range of issues caused by weakened or overspanned joists, deteriorating wood, or unstable soil. Common symptoms include bouncy or springy floors, uneven or sloping rooms, drywall cracks near doors and windows, and doors that no longer close properly. Left untreated, these problems can worsen over time, leading to structural instability. Installing professional floor supports provides immediate stabilization and restores confidence in your home’s safety.
The StrongHold® system uses galvanized steel jacks and beams that are carefully positioned beneath your crawl space. These supports are placed on engineered footings designed to spread weight evenly across stable soil. Once installed, the supports are preloaded and adjusted to transfer the weight of your home from compromised framing to solid supports. This process not only stabilizes the structure but can also gently lift floors closer to their original level. Unlike makeshift shimming or wood posts, StrongHold® supports are engineered for long-term durability and adjustability.
In many cases, yes—floor supports can reduce or eliminate sagging by gradually lifting sections of the floor. However, the main goal is stabilization, not perfection. Attempting a full lift on older homes or those with brittle finishes (plaster, tile, or aged drywall) can cause cosmetic damage. That’s why MDH’s specialists evaluate each situation carefully, making precise adjustments to improve floor performance while protecting the home’s finishes.
Each StrongHold® support is rated for up to 60,000 pounds, far exceeding the loads imposed by most residential structures. With their wide bases, the supports spread loads across a larger footprint, preventing soil compression and ensuring long-term stability. MDH’s installation team calculates the number and spacing of supports needed so the system works effectively under the specific conditions of your home.
Most installations are completed in a single day. Larger homes or projects involving additional joist or girder repair may take 2–3 days. Because the work is done entirely in the crawl space, disruption inside your living space is minimal. In nearly all cases, homeowners can remain in the home during installation.
No. StrongHold® supports are made of fully galvanized steel, which provides excellent resistance to rust and corrosion—even in humid Gulf Coast environments. This makes them a far better choice than untreated wood or uncoated steel posts, which are more likely to degrade over time.
If moisture is present, yes. Excess humidity and groundwater issues are leading causes of crawl space damage. Encapsulation with a vapor barrier and proper dehumidification keeps the crawl space dry, preventing future wood rot and protecting the investment you’ve made in floor supports. MDH often recommends pairing floor supports with encapsulation for a complete solution.
Yes. If joists, beams, or girders are rotten, broken, or undersized, MDH can sister or replace them as part of the repair process. Installing new supports on compromised wood won’t solve the issue—our team ensures all structural members are sound before supports are adjusted.
The cost of floor support repair varies depending on the number of supports needed, crawl space accessibility, and whether joist/girder repairs or moisture control are required. To keep solutions affordable, MDH offers free inspections and flexible financing options, so homeowners can address structural issues without delaying needed work.
Yes. MDH stands behind the StrongHold® system with a written warranty. This ensures your investment is protected and gives peace of mind that your home will remain stable for years to come. Pairing floor supports with encapsulation and moisture management further enhances long-term performance.
