"John was extremely communicative, honest, and punctual. He was very forthcoming with information and always responsive. We extensively remodeled a newly purchased home and John and his team finished AHEAD of schedule. We had some tough luck with prior contractors and were very thankful to meet and work with John. I recommend working with John and would work with him again!"

"Gil from NE carpentry did a lot of work for me. The most impressive was that Gil worked with me to repair my interior front porch after a massive leak during a storm destroyed it. Because my house is on the beach and very exposed, every other contractor declined the job. Gil and his team were very rigorous and patient and they did succeed in waterproofing the porch. They did rebuild it and did fantastic work. The team communicates well, is always on time, does a great job and always clean after the workday. Their prices are very fair and transparent. I will continue to work with NE carpentry and I highly recommend them."

"We hired Vinny to do a tub to shower conversion. He was the most professional contractor I have ever worked with. He gave us options and stayed within our budget and maintained his projected timeframe. We highly recommend him."

"Our house is 50+ years old and had the original casement windows, which were starting to fail. In addition, the exterior of our house need to be painted and there were a great deal of shingles or trim that was rotted and needed to be replaced. George and his team did an outstanding job, kept us informed as they went along and completed everything on time and on budget. We couldn't be happier with how the house looks. I would highly recommend Mavridis Contratcing to anyone looking for a contractor."

Unfinished Carpentry questions, answered by experts

Baseboards don’t have to be nailed into studs. However, nailing them into studs adds to their stability. When studs aren’t available, you can secure them with drywall nails directly into the drywall and adhesive. Always aim to nail into studs, especially in high-traffic or impact-prone areas.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

Yes, you can find ceiling joists using simple tools if a stud finder isn't available.

Using a hammer requires patience and a keen ear. Gently tap the ceiling in a grid pattern, listening for sound changes. A hollow sound indicates space between joists, while a solid, dull thud suggests a joist. Mark the location with a pencil and confirm by tapping from different angles.

Alternatively, you can use a nail, but this method will leave small holes. You'll feel increased resistance when the nail hits a joist. Mark the spot and repeat the process every 16 or 24 inches to map the joist locations. This method is considered less reliable than using a stud finder.

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.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.
