"It went extremely well. They knew what they were doing. When something went wrong they took care of it. They were punctual. They showed up when they said they would. They were clean and didn't leave any trash. We were extremely pleased with them. The retaining wall 8 feet high and 90 ft long. I would highly recommend them."

"This was a small job, and Alex did it right. All I needed was my cellar door rehung, as it was uneven. It turned out to be a little more complicated than that, but Alex fixed it, and I am very pleased with how it no longer is uneven."

"After originally planning on a kitchen renovation, we ended up doing an entire first-floor reno. Alex, our contractor, was exceptionally attentive and consistently went above and beyond., He was always here, making sure the job got done right. On multiple occasions, we changed our requests and he let us know our best options. We now have a beautiful first floor that was opened up after a wall was taken down and we widened our cutout and doorway between the kitchen and the family room. Our hardwood floors are exquisite and our house is much more inviting with an opened staircase plus a new prefab fireplace. We trust MountainTop so much that we intend on using them again to expand our upstairs. Alex is a good person who cares about the customer. He makes sure the job is done right and responds when you have a concern. We have recommended him before and we will again."

Barndominium Builders FAQs, answered by experts

Building a barndominium means converting a barn into a house. Barndominiums are becoming popular as spacious and stylish alternatives to typical housing structures. Old barns that become houses traditionally consist of wooden construction. However, newer structures, such as pole barns, often contain metal exteriors and roofs. Converting a metal outbuilding into a house presents an excellent opportunity to create a barndominium from metal.

Skid foundations, deck block foundations, and concrete block foundations are the most affordable shed foundation options. Of these, we recommend deck blocks. Deck blocks are easy to install and level, and they raise your shed up off the ground to prevent rotting from exposure to water and moisture. Keep in mind that deck blocks won’t resist soil movement or frost heave, so they’re not ideal in areas with expansive soil or a deep frost line.

A simple A-frame chicken coop can take as little as three hours to build, but a more substantial all-in-one coop to house a large flock can take four or five days to build. Consult a local handyperson or custom coop builder for a time estimate based on the specific details of your project.

You may need a local building permit and written permission from your homeowner’s association to install a shed, especially if you’re doing any substantial land clearing or installing electricity or plumbing. Permit requirements vary between municipalities, so research the local laws before starting your project. If you hire a contractor to build the shed, they can help determine which permits will be necessary.

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.
