"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. I would definitely recommend them to anyone needing a roof replacement."

"I was very impressed with this company from the beginning. They were very responsive from the initial review and quote, then determining a timeline that worked within our requirements and finally to delivering a high quality completed roof. They brought a full team to the job who were professional and cleaned up completely when they were done. I'd recommend them anytime."

"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

For a professional carpenter, installing a window seat can take anywhere from a few hours to a few days, depending on some aspects of the project. Aside from building the seat itself, if they have to remove any cabinets, shelves, or baseboards, that will add time to the project.

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.

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.

The easiest way to tell if a wall is load bearing is to check if it’s an exterior wall or if it runs perpendicular to the joists above and below it (or parallel to beams). Exterior walls are almost always load-bearing, and walls that run under beams or parallel to them are also usually load-bearing. There are exceptions to these rules, and walls that don’t fit into these categories can still be load-bearing. If you’re unsure, hire a structural engineer to look at your home to assess whether or not the wall is structural.

Not all porch columns are load-bearing, though they can be. Some porch columns are simply decorative. There are ways to identify a load-bearing column, like looking for visible seams and a foundation. Also, check to see if the column directly enters the ground. In some porch installations, a contractor will excavate a hole to install a column into the earth along with a buried cement base for stability.
