"Power 2 Construction & Remodeling nailed our full basement remodel and the finished project is exactly what we envisioned. Randy was always available to talk, consult on our vision, and kept us up to date on the entire process. Fully satisfied with price, quality, and the timeline it took. We would use them again for any future projects. It is hard to trust someone with such a big project but you won’t go wrong hiring Power 2 Construction & Remodeling for your next job!"

Hello there! I'm a Saint Charles/Saint Louis native and an experienced carpenter and remodeller of 17 years! Been in my own business since 2022. I love to do beautiful work at reasonable prices. I am focused on design-minded small construction and carpentry--this means that I am not primarily so focused on flashy features and the newest updates, and more focused on how I can create a project with you that makes sense with your specific house and it's architectural design. I love working with wood the most but really love doing most anything on a home and happy to do handyman work here and there as well. Please reach out so we can start a conversation! I'm happy to offer advice on how to navigate the construction industry or send you phone numbers of other great guys if you need other services. I focus on approachability and a down to earth experience. I love doing good work, i'm easy to deal with and show up when I say I will. Would love to work with you!

Customers say: Quick response

"To be truthful i was very skeptical hiring anyone to put on a new deck because of all the horror stories you hear of contractors taking your deposit and never returning to finish the job. BUTâ ¦ meeting with Jacob Quick made it all very easy. I met with Jacob many times because of my apprehension and having issues with making decisions. After signing a contract, Jacob kept in contact with me on starting date, permit issues, when materials would be delivered, and if there was inclement weather conditions that they could not work that day. From the start of teardown to the finished project, they were there every day at 7:30, making sure that time was ok with me. They had a crew of 4-5 people working all day. When an issue came up, they were up front and we discussed it. I felt very relieved that all the guys were very knowledgeable and experienced. I am picky when it comes to details and the entire crew were all very concerned about the littlest details. Brian was also great at answering my questions as the deck was being built. They wanted me to be highly satisfied and i surely was. Not only did they do an outstanding job building the sturdiest deck around but when they left my house, you couldn't even tell they were thereâ ¦ my yard was clean. Soâ ¦ yes i would hire them again. They made the entire experience easy peasy for me. Also kudos to the other guys on the team who also worked their butts off in the 100 degree weather. Put your mind at ease and hire Jacob Quick with Master Remodeler. You can come by and check out my deck!!"

"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Unfinished Carpentry FAQs, answered by experts

Joists do distribute their load to beams, but they don’t sit on top of the beams. Instead, home builders nail or screw the joists directly to the beams such that the end of the joist butts up against the edge of the beam. Beams can sit on other beams for support, but you’ll never see a joist sitting on top of a beam or another joist.

Yes, using certified lumber and engineered wood products for reduced environmental impact.

You can enclose an open carport, however, there are several things to consider before opting to do so. You'll want to check local building codes and permit requirements before proceeding to make sure it’s legal. While you can sometimes stick-frame a carport enclosure, pre-fab kits are also available. Remember that you'll likely need to meet concrete slab regulations and provide lighting inside the structure. Both of which could substantially drive up costs.

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.

The average cost of DIY window framing is about $40 to $60 in materials. If you hire a window treatment professional, you’ll pay for materials plus labor costs—anywhere from $250 to $800 per window. The final cost is highly dependent on the window size, as larger windows are heavier and more difficult to install, as well as the type of window framing material.
