"I can't speak highly enough regarding Jeff Lemires's work. I've worked with various contractors throughout my career and have never come across one who is not only thoroughly trained and talented in the trade but who is also scrupulously honest and trust worthy. I have reviewed a number of individuals with whom I've conducted business in the upper valley but never anyone who so richly deserves a perfect score.. This gentleman deserves only those clients who understand and appreciate quality at its best at a fair and reasonable price.

"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."

"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

Balcony construction or replacement typically requires a building permit from your local permitting authority. Safety and building integrity are the main reasons for the need to obtain a permit and the subsequent inspections. In some cases, especially cantilevered balconies, your municipality may also require the oversight and signature of a structural engineer.

Removing a load-bearing wall is best handled by professionals. However, if you have the skill set and decide to DIY the project, you will still need at least one additional person to assist you. Aside from helping with demolition, you'll need another hand to install the new support beam.

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.

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.

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.
