"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."

"We originally contacted Charlie about damaged siding near our front entrance, but also needed some masonry repairs on our steps. Charlie explained both projects and gave us a clear estimate. The team did a great job matching the siding and repairing the deteriorated mortar. Everything was completed neatly, and they left the property clean. Very satisfied with the experience."

"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."

"Don came on the date and at the time he promised.  I showed him the fence and explained what I wanted done.  He made a list of supplies he would need and he measured the wood.  He then went to Home Depot and purchased the supplies.  He did a good job and finished when he said he would.  I have since hired him to do another job for me.

"All of the work was done quickly, professionally, and met my high standards. The only problem arose when they installed my railings while I was out without having me select the style. I came home on the last day of work and everything was complete, even railings that I had not seen or approved. Initially, I didn't want to make them redo it. I thought I could live with it. I paid in full and they left. Ernesto called my husband to make sure we were happy. Everything seemed great, the work was well done, and everyone was professional. However, a few days later I realized I really hated the materials they chose for me. When my husband called back to see if they could change out the railings for us, they said it would cost about $500. I know I paid in full and approved the job, but after $8,000 worth of work, I thought it distasteful to be charged more money to change out materials that I never approved in the first place. I recommend their work, but be sure you approve every single material prior to installation.

Barndominium Builders FAQs, answered by experts

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Yes, barndominiums can be two stories. Blueprints for barndominiums can safely support multiple stories or vaulted ceiling heights of 14 feet or more. Barndominiums are prized for their ability to be modified and customized to suit the builder’s preferences, and many barndominium construction companies offer a variety of different floor plans to choose from.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

It can, especially with the rising popularity of treehouses that go beyond the ones designed for kids. Adults can now use them as office spaces, yoga studios, or quiet treetop retreats. That said, a treehouse can appeal to families with children or adults who might want to convert it into a space of their own. Depending on the buyer, they may be willing to pay extra for the unique feature.

The term “cottage” is subjective, so there’s no rigid definition, but it generally refers to a small home with simple and purposeful architecture that embraces nature and focuses on charm over everything else. Cottages are typically 1 or 1 1/2-stories tall, usually with gabled roofs, and are built out of natural materials that help make the structure a part of the surrounding nature rather than something that stands out from it. A big part of what makes a cottage a cottage is the decor, which includes natural materials from the nearby area.
