"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

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors. 

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.

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 hanging a door frame, it’s recommended that you use screws, not nails. Screws are more secure, easier to tighten, and easier to remove if you need to adjust the frame. On average, the cost to replace a door frame is about $400, but you can save on labor costs if you’re confident in your ability to DIY the project. 

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.
