Unfinished Carpentry questions, answered by experts

Professionals charge between $60 and $95 per hour to install ornamental porch columns. The amount of time they need varies based on the condition of the porch, whether they need to remove old columns, and if there is any damage to your porch's structure. This cost can increase if more issues come up during the installation process.

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

Bow windows need support because they are large and extend out from the exterior wall of the home. Bow windows may extend 1 foot to several feet from the outside of the home, so you’ll need to provide additional support to handle this weight. A window contractor will be able to provide the proper amount of support for your new bow window.

There are approximately 5.33 board feet in a 2x4. You can use the board foot calculator in this article to easily find the answer. A 2x4 is 2 inches of thickness by 4 inches of width, so you need to find the length, with 8 feet being the most common. You’d use the calculator here to multiply 2 times 4 times 8, and then divide by 12, arriving at a total of 5.33 board feet. 

For a professional carpenter, installing a window seat can take anywhere from a few hours to a few days, depending on some aspects of the project. Aside from building the seat itself, if they have to remove any cabinets, shelves, or baseboards, that will add time to the project.
