"Closet expansion!! I don’t normally do reviews, but I had to share my experience with this company. OUTSTANDING WORK! Dan and Joe demolished 2 walls and rebuilt them in one day including sheet rock. From there Kyle took over the project spackling, painting and hanging the barn door. All of their work was super neat, clean, and meticulous. Frank was my salesman, and he was great. Price was very fair. John’s communication was constant and always appreciated. I also appreciated that he walked the job before and after to make sure I was happy with what I was getting. Better than any other contractor I’ve used in the past. Ten out of ten, a must hire company."

"Ronda came to us through our general contractor. She assisted us in selecting our cabinets, counter tops, hardware and tile. She met with us multiple times at our house to work through the cabinet design. And we met with her multiple times at her studio and the tile shop to select our counter top and tile. Always ready to help, she is knowledgeable and has innate design ability. More than that, she can explain her design choices, yet is willing to discuss alternatives and work through the design process in a collaborative manner, bringing many ideas to the table – or kitchen, as it were. She listens to her clients and was able to translate our ideas into a comprehensive design. Throughout the process Ronda worked with our contractor and with us to make certain everything came together as planned. While there were a number of minor snafus, she was always there to make certain issues were resolved and to keep the job moving ahead. Cabinets and counter tops are a significant portion of the remolding cost. Cabinet manufactures are not all that interested in dealing directly with the customer. Rather, they work through their distributors. We purchased our cabinets through Ronda who has a strong working relationship with the manufactures she deals with and can easily work out issues. Thank you Ronda for a wonderful new kitchen!"

Unfinished Carpentry FAQs, answered by experts

Yes, you will need a jack for a rim joist replacement. To prevent sagging and facilitate the removal of load-bearing wood, you’ll need to relieve the pressure from this joint before beginning work. 

Due to hydraulics and other specialized equipment, a sill plate and rim joist replacement are not typically a DIY project. Hiring a professional structural engineer and experienced contractors is the best approach to replacing rotted sill plates and rim joists.

Yes, professionals can install new frames, trim, and threshold adjustments for a complete finish.

The best way to calculate framing costs is by basing your costs on the square footage of your home. On average, framing your home could cost anywhere between $7 and $16 per square foot. 

To ensure you don’t go over budget, base your estimates on the higher end of the price range. If you know you’re going to use high-end materials or require a custom or complex build, you might even want to tack on an additional 5% of your budget.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.

It's possible to turn your carport into a living space, but there are additional factors to address over turning it into a garage. HVAC, plumbing, and electricity won't be optional, and you'll need finished flooring, drywall, trim work, and legal ceiling height, for starters. Also, keep in mind that living space conversions may require upgrading the foundation underneath, and the permits might be more expensive as well.
