"Jose and his team were extremely professional, highly knowledgeable, and incredibly helpful throughout the entire project. He provided a fair price without compromising on quality, and his attention to detail was amazing. The final result came out even better than I expected! One of the things I appreciated most was how clean and organized they were. They always kept the work area neat, taking extra care to minimize dust and prevent it from spreading to other parts of the house. I would absolutely hire him again and highly recommend Jose to anyone looking for a skilled, reliable, and detail-oriented contractor. A true professional!"

"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."

Unfinished Carpentry FAQs, answered by experts

Begin by analyzing the blueprints and gathering the proper materials before framing a house. With the prep stages behind you, begin by framing the floor of a house on the newly set foundation. Exterior and interior walls come next, along with rough openings for doors and windows. Contractors will then add ceiling and roof rafters to finish things off. 

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.

House framing can be expensive because the materials are pricey, and the job requires a high level of expertise. The more complex the plans, the more expensive the job, but even the most basic frame needs to be installed with high-quality materials and precision. When pricing your home’s framework, remember that a sturdy frame is necessary to create a safe structure.

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. 

Most load-bearing walls are exterior, though they can also be interior.
