"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"I would not hesitate for a second hiring Horsman Builders for any of my house projects or remodel, in fact that is what I will do from now on. I was nervous starting a project having to handle things on my own but Tim made me comfortable with a detailed estimate, answered all my questions, kept me informed about the work, the site was always clean and the result is awesome, my neighbor was commenting on how great it is just checking it out from a window. Fair price, excellent quality and great customer service. A+"

"This is the 2nd job we has Steve do for us. The was a min bathroom renovation and also kitchen backsplash. Bathroom came out great. He walled off a second door to access the bathroom, ripped out old tile, and put down new tile and installed a new vanity. Very happy with the finished product. Steve also did the backsplash in the kitchen. It came out perfect. I would definitely recommend Steve for any home improvement projects you may have."

Barndominium Builders FAQs, answered by experts

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.

Barns and barndominiums are most commonly painted red, like barns depicted in movies and paintings. The practice of painting barns red dates back to America’s colonial days, when new farmers would borrow the European practice of mixing linseed oil with ferrous oxide to coat the barns in order to protect them from the elements, leaving the structures with a red color.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

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.

Any type of construction that damages a tree’s roots via soil compaction can be dangerous, and is one of the primary causes of mature tree death in residential areas. Simply putting lots of weight on the ground around the tree, like construction supplies, trailers, and equipment, can kill roots near the surface. Of course, installing new foundations, patios, or utility lines can cut through nearby tree roots. Accidentally striking a tree with equipment or supplies is rarely a problem, but can cause damage of its own, too.
