"I was so stressed out with being a first time home owner, UNTIL I met Mike and his team! They went above and BEYOND! They helped with so much more than just what they were hired on to do. They literally made my house a dream come true. I love my home now. It went from ugly to BEAUTIFUL in about two weeks worth of time... The remodel was SOOOOOO smooth and came out FANTASTIC! I tell everyone and their mother to use these guys. I cannot thank them enough or give them enough credit. I will use them for all future endeavors. I LOVE these guys! Mike is the bestest and will get what you want done fast and seamlessly. HE IS TOP NOTCH and treats you like family."

"We had out kitchen remodeled and James from Royalty Construction did the Kitchen tile work. He was punctual, professional and did a great job in our kitchen. I am in the real estate industry and have worked with many contractors, I can attest he is by far one of the most meticulous contractors I have worked with. I would definitely recommend his work."

Unfinished Carpentry FAQs, answered by experts

Converting a carport into a garage can vary in difficulty depending on its configuration, the condition of the foundation or slab, and its location relative to the house. The process has a lot in common with a home addition, but you can often skip non-essential finishes like fine flooring, trim work, or even drywall and HVAC. The conversion requires experience with drywall, insulation, and other building materials to ensure it’s done safely and correctly. While it might be possible for a DIYer with the proper tools and skills to do the work, it is a complicated and potentially dangerous job. If you’re new to basic construction, it's best to leave this project to the professionals.

The primary parts of a house that need framing during construction are floors, exterior walls, interior walls, and the roof. The framing in these areas provides the skeleton for adding other materials over the top. With walls, for example, contractors can hang drywall over the interior walls and siding over the outside of the exterior walls. Proper framing ensures a sturdy house that is built to last.

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.

It’s sometimes safe to replace a load-bearing wall with a beam, but you need a structural engineer to sign off on the project. You’ll also likely have to upgrade to a steel I-beam or another material that’s stronger than wood to maintain the level of support you need without the wall underneath.

To calculate the number of linear feet of baseboard you’ll need, measure the length of each wall of the room you’re installing them in as close to the floor as possible, rounding up to the next full linear foot. If it’s your first DIY molding job, having a few extra feet on hand for miscuts is a good idea.
