"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

Unfinished Carpentry FAQs, answered by experts

There are a few easy ways to locate a wall stud without a stud finder. First, try knocking on the wall with your knuckles. Most parts of the wall will sound hollow, but when you tap over a stud, it will sound more solid. Alternatively, since studs are spaced 16 or 24 inches apart, you can measure those distances from a corner of the room, which will always have a stud.

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.

You may need a permit to install your window seat. Even though it's an indoor modification, some municipalities require permits for any built-ins added to homes. Check with your carpenter or, if you're DIY-ing, do some research on your city's requirements.

Installing an ornamental or decorative porch column takes around three to five hours. Structural columns take longer because your pro has to install a jack to hold up the roof while switching the column out. If there's any structural damage, it can add several days to the timeline to repair the damage.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.
