Customers say: Quality work

"Bear Remodelling just finished our kitchen remodel and we couldn't be happier! Our 1980s kitchen was cramped and dark, but now it's open, bright and functional. The team guided us through picking cabinets, countertops, and backsplashes that worked together perfectly. What impressed me most was how clean they kept our home during the process - they put up plastic barriers and cleaned up daily. The project manager kept us updated with daily progress reports and was super responsive whenever we had questions. The new island they installed gives us the extra counter space we desperately needed. Worth every penny!"

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

Barndominium Builders questions, answered by experts

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.

Building a treehouse can vary in difficulty depending on factors such as design complexity, size, and the builder’s woodworking experience. Basic treehouses with simple designs can be manageable for DIYers with some carpentry skills, while more elaborate structures may pose challenges. Adequate planning, research, and careful execution can make the process more manageable, and resources like premade plans or professional assistance are always available for additional support.

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.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best. 

Prefab sheds can be worth it, depending on your needs and goals. If you want to build the shed yourself or have a quick project turnaround, then a prefab shed will likely be worth it. If you want something more customized, then starting from scratch may help you achieve your goals better than a prefab could.
