To address rusty ceiling joists, first assess the damage. If rust is superficial, sand the surface, remove loose paint, and apply rust-inhibiting primer followed by exterior-grade paint. For severe corrosion, replace affected joists. Always wear gloves, goggles, and a respirator to avoid inhaling particles. Prioritize safety by supporting the ceiling with temporary braces before removal.

The primary risks of rusty joists include structural weakness and fire hazards. Corrosion weakens steel members, reducing load-bearing capacity by up to 30% (National Association of Home Builders, 2022). Unaddressed rust can lead to ceiling collapse, costing $5,000–$20,000 in repairs (HomeAdvisor, 2023). Lead paint removal is critical if the joists were painted before 1978, as lead exposure causes neurological damage (EPA, 2021). Sanding without a HEPA vacuum releases toxic dust, necessitating proper containment. Replacing joists costs $300–$1,500 each (Remodeling Magazine, 2023), but prevents long-term safety risks. Proactive maintenance extends joist lifespan by 15–20 years (APA, 2020). Ignoring corrosion increases insurance premiums by 15% (III, 2022).
