Unfinished Carpentry FAQs, answered by experts

You can choose 5/8-inch plywood or 3/4-inch plywood—anything thinner than these sizes may not withstand the impact of debris propelled by strong winds or can be easily torn off by intruders. Remember that the durability of the wood board is crucial, particularly for safeguarding your windows during severe storms. The effectiveness of using wood boards for protecting the investment you made in your home relies on using the appropriate material and ensuring proper installation.

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

Balcony construction or replacement typically requires a building permit from your local permitting authority. Safety and building integrity are the main reasons for the need to obtain a permit and the subsequent inspections. In some cases, especially cantilevered balconies, your municipality may also require the oversight and signature of a structural engineer.

Removing a load-bearing wall affects the structural integrity of your home, so you’ll need a permit before starting the work. Building codes vary by municipality, and obtaining a permit and having the work inspected after completion will ensure you’re in compliance with all applicable regulations.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.
