"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

Duration varies by project size, but average-sized homes typically take a weeks.

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.

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.

Bump-out additions can add some space to a closet without requiring any significant structural work. This entails pushing back the existing rear or side of the closet, simply moving the wall into either an adjacent room or unused space. For ground-floor closets, this could even be extended to the exterior of the home, but that has its own complications. Bump-outs are a good discussion to have with your contractor if you’re just looking to increase the space a little—not renovate the entire closet space.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.
