"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Marquis Roofing did a fantastic job on our roof. The job was completed in one day. Tom Marquis's crew was professional, highly qualified and courteous. Once completed, the job site was completely cleaned of any building material and nails. I would absolutely hire Marquis Roofing again should I ever need another roof job done."

"We unfortunately got scammed by a previous contractor in 2021 when we purchased our house in Elizabeth City. Our home reno paused for about a year until we met Thaad. He has been working with us through our whole home reno, he has done our living room, our bathroom, and has helped us finish our kitchen. This guy is one of the best, honest, and most hardworking contractor we have ever worked with. If you want reliability, great service, and great communication then he is your guy."

"Cully removed old walls in a hallway and installed new sheetrock, did
all of the prep work and painted.  The job required removing and
restoring a great deal of molding, and he was careful to try to preserve
as much of it as possible.  He replaced the few pieces that could not
be saved and reinstalled all of the freshly painted molding.  He also
arranged for an electrician to install several new outlets and new
hard-wired smoke detectors. The job had to be done on a very specific
time schedule, and there was no room for schedule shift. Both Cully and
the electrician complied perfectly with the timeframe and by working
late, completed the job in record time.

"The man I talked to was very professional and timely. However, he explained that this particular job was beyond the scope of what their company does. I would certainly use them on another 'issue'.

Unfinished Carpentry FAQs, answered by experts

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.

Professionals charge between $60 and $95 per hour to install ornamental porch columns. The amount of time they need varies based on the condition of the porch, whether they need to remove old columns, and if there is any damage to your porch's structure. This cost can increase if more issues come up during the installation process.

There are approximately 5.33 board feet in a 2x4. You can use the board foot calculator in this article to easily find the answer. A 2x4 is 2 inches of thickness by 4 inches of width, so you need to find the length, with 8 feet being the most common. You’d use the calculator here to multiply 2 times 4 times 8, and then divide by 12, arriving at a total of 5.33 board feet. 

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

Accurate measurements, sturdy materials, and seamless integration with other structures.
