"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.

"Responsive. Respectful. Reliable. MRC Construction did an outstanding job with my new siding and gutters! This was my first big home improvement project. I set a budget, began the research and ultimately requested bids from four suppliers. MRC was the most competitive, offered the product selection and warranty I was looking for and their schedule fit mine. Rodrigo is professional and patient and answered all of my questions. Marco managed the onsite work flawlessly. From the first phone call to the last walk through, MRC Construction is FIVE stars. I highly recommend MRC Construction and will go back to them for my future projects."

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.

"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."

"Oliver came to our home to do a free estimate within just a day or so of using Home Advisor. His price was very reasonable. And he was able to start the project very quickly. He did a wonderful job with the vinyl siding installation. I highly recommend Oliver Druen Carpentry."

Unfinished Carpentry FAQs, answered by experts

When deciding whether to use nails or screws for framing, the specific needs of the project must be taken into account. Nails have long been the go-to option for framing due to their affordability, ease of installation, and ability to withstand shear forces. They are perfect for structural framing projects where fast assembly is essential. In contrast, screws offer exceptional holding power and are particularly useful in situations requiring increased strength and resistance to pull-out forces. For projects that prioritize accuracy and long-lasting quality, screws may be the preferred option, though nails remain a dependable and efficient choice.

House framing can be expensive because the materials are pricey, and the job requires a high level of expertise. The more complex the plans, the more expensive the job, but even the most basic frame needs to be installed with high-quality materials and precision. When pricing your home’s framework, remember that a sturdy frame is necessary to create a safe structure.

Using a steel frame may raise the value of your home. Steel is more heat resistant, has better longevity, and doesn’t need any upkeep compared to traditional wood. You can also customize a steel build a little easier than other materials like brick, concrete, and vinyl—which have trouble bending and adapting to renovations.

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.

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.
