"Rea Professional Contracting did an outstanding job remodeling our bathroom. We did a full remodel of everything, down to the studs. Their work is exceptional. We had to be out-of-town for a few days considered cancelling our trip. No need; Rea treated our house as if it was their own. They cleaned up nightly and were very respectful our privacy and the fact that we were "living" here while they were working. Would happily recommend them to anyone without hesitation."

"Gabrielle is extremely professional, knowledgeable, and reliable. We recently needed repairs on two of our new kitchen cabinets, and after contacting him, he was able to come by within hours to assess the issue and complete the repairs the very next day. His workmanship was exceptional, and the cabinets now look perfect. We truly appreciated his responsiveness, attention to detail, and commitment to quality. I highly recommend his services to anyone looking for a skilled and dependable carpenter."

Unfinished Carpentry FAQs, answered by experts

Proper Murphy bed installation minimizes the risk of wall damage. A secure attachment requires making some holes for anchors or brackets, but these can be easily patched if the bed is removed. To ensure the installation is done correctly and safely, hiring a professional is recommended, especially if you have limited DIY experience.

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

Metal stud framing parts include the studs themselves, upper and lower tracks that act as top and bottom wall plates, various angle fasteners and clips, screws for fastening pieces togeher, metal straps, c-channel supports, and thicker steel supporting structures. Roof framing metal components include pre-fabricated trusses, heavy-gauge stud pieces, and various plates and fasteners.

Building involves setting foundation posts, framing with durable wood, adding roofing support, and protecting from elements with water-resistant finishes.

Not all porch columns are load-bearing, though they can be. Some porch columns are simply decorative. There are ways to identify a load-bearing column, like looking for visible seams and a foundation. Also, check to see if the column directly enters the ground. In some porch installations, a contractor will excavate a hole to install a column into the earth along with a buried cement base for stability.
