"This project was a pleasure. Joe was great to work with at all stages of the project. He did a great job communicating about his schedule and always showed up when he said he would. The project met all of our expectations. We would definitely hire again if a new project comes up."

"We had searched for a roofing contractor for several weeks to replace deteriorating ridge cap shingles, but it was tough to get a response from most. Rick responded within a day, and came out to look at the project. He described what he would do and the materials he would use. A contract followed a few days later with an estimated start date. Price looked very reasonable. We had a little confusion leading up to the job due to difficult weather, but Rick was in constant contact throughout. In the end the crew showed up one day before the estimated start date. They started at 9:00am and finished the job by 3:00 the same day. Work was done professionally and they cleaned up after themselves completely. Rick was very considerate of our Covid concerns, and careful to wear a mask when speaking to us. Overall they did a great job, for a good price, and were easy to work with. Highly recommended."

Unfinished Carpentry FAQs, answered by experts

Most of the time, you’ll want to use screws on your subfloor rather than nails. Nails can actually weaken plywood, whereas screws can easily penetrate without damage. They also form a more secure connection because of their shape, preventing squeaky floors and tightly holding the subfloor in place. That said, some contractors do prefer nails depending on the type of floor covering because they allow for more flexibility.

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.

Your local building code will list all the framing requirements for whatever type of structure you're building. Most exterior walls require spacing of 16 inches on-center, while many non-load-bearing interior walls only require 24 inches of spacing. However, there are also varying requirements depending on your construction material, so checking your municipality's rules is essential.

For a professional carpenter, installing a window seat can take anywhere from a few hours to a few days, depending on some aspects of the project. Aside from building the seat itself, if they have to remove any cabinets, shelves, or baseboards, that will add time to the project.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.
