"Went wonderful with the contractor. They were great to work with and helped us navigate a very troublesome insurance company. They drove from northern Virginia to silver spring to do the work as well, not any easy task and a long commute in traffic. They were just great."

"wasn't able to do the project in the time frame so we didn't use him.  He was very quick to call back and set up a meeting.  Said he would be able to do the job but then saw it and said no he couldn't.  His pricing was good but he was just a one man service with no helpers.

Unfinished Carpentry FAQs, answered by experts

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

When deciding whether to use nails or screws for framing, the specific needs of the project must be taken into account. Nails have long been the go-to option for framing due to their affordability, ease of installation, and ability to withstand shear forces. They are perfect for structural framing projects where fast assembly is essential. In contrast, screws offer exceptional holding power and are particularly useful in situations requiring increased strength and resistance to pull-out forces. For projects that prioritize accuracy and long-lasting quality, screws may be the preferred option, though nails remain a dependable and efficient choice.

Yes, you can hang picture frames, shelves, and other items on Trusscore panels. For lightweight items (less than 30 pounds), the company recommends using adhesive strips rather than nails or screws. However, you’ll need to secure heavier objects to a stud in the wall. In these situations, Trusscore recommends cutting away the panel material and fastening the object to the stud with metal hardware.

You can enclose an open carport, however, there are several things to consider before opting to do so. You'll want to check local building codes and permit requirements before proceeding to make sure it’s legal. While you can sometimes stick-frame a carport enclosure, pre-fab kits are also available. Remember that you'll likely need to meet concrete slab regulations and provide lighting inside the structure. Both of which could substantially drive up costs.

No rules state how much of a load-bearing wall can be removed. Rather, you need to adequately support any area that is removed. Support should always be added to as much wall area is being removed. Failing to support the area properly will result in structural damage.
