"We found REA Pro through positive reviews online. Jaime Rea was one of several contractors we interviewed. He is very prompt, energetic, and an excellent communicator. After an initial phone call and site visit, Jaime provided the estimate within a couple of days. The project – which included renovating 5 decks, repairing siding, and painting the exterior of the house – was started on time and completed within Jaime’s time estimate. His crew was very professional and personable and a pleasure to work with. We were really impressed with the quality of the work and their attention to detail. We are very happy with the final result, and would hire Jaime and his crew again for other projects."

Unfinished Carpentry FAQs, answered by experts

Stick frames, metal frames, or prefabricated concrete frames are included in framing a house, along with creating the framework and space for windows, doors, and entryways. Other aspects of developing a home—like drywall, insulation, windows, doors, and more—are not included in the cost to frame a house.

Installing a tongue-and-groove wall requires similar techniques to those associated with installing shiplap. However, because of the precision necessary to make each board fit perfectly and the increased material prices, the cost is higher than that of shiplap installations. Expect to spend between $2 and $6 more per square foot for tongue-and-groove walls versus shiplap ones.

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

Homeowners can increase the usefulness of their garage space in other ways, and one option is to extend the length of the garage by making it deeper. The process is similar to traditional garage extensions, but the end product is a garage with a different layout rather than additional parking spaces. 

To calculate the number of linear feet of baseboard you’ll need, measure the length of each wall of the room you’re installing them in as close to the floor as possible, rounding up to the next full linear foot. If it’s your first DIY molding job, having a few extra feet on hand for miscuts is a good idea.
