It’s sometimes safe to replace a load-bearing wall with a beam, but you need a structural engineer to sign off on the project. You’ll also likely have to upgrade to a steel I-beam or another material that’s stronger than wood to maintain the level of support you need without the wall underneath.

The cost to convert a carport into a garage averages about $22,000, ranging from about $15,000 and $55,000. Additional cost factors to consider include size, time of year, and how much of the carport you can reuse. Other cost factors include the kinds and amounts of materials used, such as:

• Add insulation: $1 per square foot

• Add drywall: $1–$3 per square foot

• Add window: $450–$2,000 per window

• Add outlets: $75–$500

• Add garage door: $250–$11,200

• Enclose framing: $5–$13 per square foot

• Replace roofing: $1,000–$2,000

Yes, you will need a jack for a rim joist replacement. To prevent sagging and facilitate the removal of load-bearing wood, you’ll need to relieve the pressure from this joint before beginning work. 

Due to hydraulics and other specialized equipment, a sill plate and rim joist replacement are not typically a DIY project. Hiring a professional structural engineer and experienced contractors is the best approach to replacing rotted sill plates and rim joists.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them.
