Frequently asked questions

What causes floor joists to fail or sag in Gulf Coast homes?
Excess humidity and repeated wet/dry cycles are the big culprits. Moisture promotes fungal decay and wood fiber loss; add undersized or over-spanned joists, plumbing leaks, termite activity, and soil movement under piers, and you get deflection (sagging), bouncing floors, nail pops, and interior cracks. HVAC condensation, unsealed vents, and poor drainage accelerate the problem.
Common red flags include spongy or “bouncy” floors, slopes toward interior walls, doors rubbing or drifting open, cracked tile or drywall at door corners, persistent squeaks, visible rot at the band/rim, rusted fasteners, and dark staining on joists or subfloor. A musty crawl space or fallen/damp insulation also points to moisture affecting the framing.
We start with a full crawl space inspection—documenting moisture levels, wood condition, bearing points, pier spacing, and load paths. We identify root causes (moisture, pests, over-span, settlement), measure deflection, and provide a written plan with photos, recommended structural repairs (sistering, scabbing, beam repairs), support upgrades (StrongHold® adjustable jacks, new pads/piers), and moisture management (encapsulation, drainage, dehumidification).
Sistering adds new lumber alongside existing joists to restore stiffness and bearing capacity, while partial scabbing targets localized damage around notches, plumbing cuts, or rot at supports. Full replacement is recommended when decay or insect damage is extensive. Repairs are often paired with a new support beam/girder and StrongHold® adjustable floor supports to reestablish a straight, continuous load path.
We can often achieve meaningful lift, but we lift conservatively to protect finishes. A staged or limited lift is usually best for older homes so brittle materials (tile, plaster, crown, etc.) aren’t stressed. The primary goal is stabilization; lift is performed where practical and safe.
If moisture contributed to the damage—and it usually does along the Gulf Coast—structural repairs should be paired with moisture control. Encapsulation, perimeter drainage/sump where needed, sealed vents, and a properly sized dehumidifier help prevent new deterioration and the return of joist deflection.
Most projects take 1–3 days depending on access, extent of damage, and whether moisture control or drainage is added. You can typically stay in the home, and we keep the workspace tidy and remove debris at completion.
We match or upgrade species/grade and size (e.g., No. 2 Southern Pine or better, LVL where appropriate). Beams and posts are sized per span/load. StrongHold® Floor Supports use fully galvanized steel set on wide, engineered pads for better soil bearing, and all fasteners/connectors are code-compliant and corrosion-resistant.
Often, yes. Stabilizing and, where feasible, lifting the structure can relieve binding at door frames and reduce new cracking. Existing cosmetic issues may still need minor rework after the structure is stabilized; we’ll set expectations on what should improve versus what needs finishing work.
Pricing depends on crawl space size/height, access, number of joists and length of sistering, need for new beams/pads/piers, and whether encapsulation/drainage is included. MDH provides free inspections and written proposals with line-item options and flexible financing.
When proper structural repairs are combined with moisture management, results are long-lasting. Galvanized, adjustable supports allow future fine-tuning if the home or soils change, and we provide maintenance guidance to protect your investment.
Yes. We maintain termite inspection gaps/visual bands per local pest providers, use treated wood where needed, and follow local code for ventilation changes, electrical needs (for dehumidifiers/sumps), and structural details. We’re licensed and insured across AL, FL, and MS.
Plan an annual crawl space check for moisture, RH (target 45–55%), and wood condition, along with dehumidifier filter changes and sump testing if installed. Adjustable jacks can be quickly re-leveled if a seasonal tweak is needed. MDH can schedule simple annual service to keep everything dialed.
