"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!"

"Jamie and his crew were professional and an absolute pleasure to work with. We love our new bathroom and couldn’t be happier with the job Rea Pro did. Jamie was a great communicator, responded quickly to all our questions and was amazingly helpful in pulling together the vision for our renovation. The crew worked everyday and were extremely neat and respectful of our home. The job was finished on schedule and we were extremely pleased with the whole process. We would highly recommend Jamie and his team."

"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

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.

Baseboards don’t have to be nailed into studs. However, nailing them into studs adds to their stability. When studs aren’t available, you can secure them with drywall nails directly into the drywall and adhesive. Always aim to nail into studs, especially in high-traffic or impact-prone areas.

Yes, a 2x6 should hold a porch swing and safely support the load. A smaller joist runs the risk of it not offering enough support for the swing. If you have a joist smaller than 2x6, add additional bolstering support.

Carpenters are trained to take on a wide range of home projects. You can hire a carpenter to do framing, roofing, build custom furniture, and make significant upgrades to your home. General carpenters are usually able to handle most jobs. However, you may also choose to hire a carpenter who specializes in a specific type of carpentry. 

Removing a load-bearing wall affects the structural integrity of your home, so you’ll need a permit before starting the work. Building codes vary by municipality, and obtaining a permit and having the work inspected after completion will ensure you’re in compliance with all applicable regulations.
