"Angelo went above and beyond to help me with getting a Permit for my Gazebo. He researched and contacted the right people to get answers about codes and what was needed. I had been going back and forth for weeks trying to find out what was needed with no help from the builder and the town. Angelo found the answers in one day. I highly recommend Joseph and Sons."

"I contacted Mr. Handyman to build an outdoor enclosure for my cat (catio). From the moment, Taneesha answered my call to the time they completed the catio, they were phenomenal to work with. I had been struggling to find someone who had done this kind of job before, but Taneesha made me feel very comfortable that they could do this job. They sent Mike over and he was amazing. He has a cat of his own so he knew exactly why I wanted a catio. We looked at a few pictures together and he designed an amazing catio for us. His workmanship and attention to detail was simply inspiring. He thought of every single place a cat could try and escape from and took care of it. I am truly so impressed by him. And while the work was being done, Ron provided regular updates on Mike's availability and assured us that they would complete the job in a decent timeframe. I would recommend them highly for their competence, transparency, workmanship, and professionalism. I can't wait to do more work with them, starting with a phase 2 of my catio!"

"JM Contracting Group did a great job building my deck. Not only did they start and finish the deck well before the due date, they paid attention to the details, and John helped me with the selection of the deck floor. I now have a beautiful deck."

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

Barndominium Builders FAQs, answered by experts

In the U.S., original and converted carriage houses are most often found in New England, New York, and other parts of the Northeast. New construction carriage houses can be found across the country, and are often added to properties with Colonial-style homes for additional living, storage, or work space, although they can be found in many different styles.

The difference between a pole barn and a stick-built barn is in the construction. Large poles in the ground provide support for pole barns. For stick-built barns, 2-by-4 or 2-by-6 lumber (known as sticks) create a frame around load-bearing beams. Stick-built construction is far more popular for residential homes. Pole barns are more cost-effective because they require fewer materials and less labor.

Trex is not stronger than wood, but it lasts longer than wood and is heavier. Trex holds up well to the elements and is resistant to termites thanks to its resilient composition of plastic, reclaimed wood, and sawdust. Trex decking is rot and warp-resistant, making it especially useful in areas that experience a lot of snow and rain.

The construction stage is almost always the longest part of building a house. Within this stage, framing often takes the most time, lasting anywhere from one week to a couple of months, depending on the home's size, the crew, and the time of year. Other parts of the construction phase include pouring the foundation and installing doors, windows, a roof, siding, drywall, and flooring. The planning and design phase can also be very time-consuming, sometimes taking months or even years, especially for a custom home. The final finishing process, which includes painting and installing trim, is typically shorter than the construction or planning stages.

The time it takes to build a shed heavily depends on the type of shed you buy. A prefab shed can be built in 4 to 8 hours, while a custom shed will be built off-site over the span of 2 to 5 days. It then takes a few hours, depending on the location, to move the finished shed to its final location.
