"Steve did a nice job but took about twice as long as I might have expected the job to take. I had a piece of Wayfair cubicle furniture to assemble and 4 pictures to hang and it to 4.25 hours to complete. Steve was polite and professional."

"BiiLT Contracting replaced our carpet flooring with LVP and we love it! I highly recommend BiiLT Contracting for any construction project and had a great experience working with them: easy to contact and schedule, prompt responses, by far the lowest quote, great customer service, very professional, organized, friendly and considerate staff, worked within set budget, workers cleaned up project area every day at the end of the work-day."

"Wilson Renovations LLC did an amazing job. They were very curtious and hard working. They went above and beyond my expectations. My cieling was falling down and not only did they replace that, they repainted my bedroom as well. Looks brand new! They were also able to do some odds and ends in my bathroom. I would highly recommend them for your next project. The pricing was very reasonable and financing options were available which worked great for me as a single mom."

"They did the painting while we were away. We had them return to fix some things. They did that the next day. All went smoothly. The only problem we had was the carpeting was dirty when we got home. Very nice couple to work with."

"Serge was great! First, he came out and gave us an estimate within a few days. We had several others provide estimates but we chose Cozy Home, and I am glad we did. His price was the best; we felt the others were really overpriced for the kind of job it was. He was very easy to work with, and quickly responsive to communication - a real bonus! Our porch looks great. We plan to hire him for our next project."

Barndominium Builders FAQs, answered by experts

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.

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.

While building a treehouse isn’t necessarily a death sentence, damaging the trunk is one of the ways to kill a tree. If you’re concerned about the tree, opt for a treehouse support system rather than attaching it directly to the trunk. This may involve using bolts and brackets to affix the structure to the tree's branches or establishing a standalone support system that remains unattached to the tree.

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.

Choosing a suitable backyard playset that’s age-appropriate and entertaining for your children is worth the cost. A backyard playset you can update and upgrade as your kids grow offers even more benefits. Although a playset won’t substantially increase your home’s value, it won’t negatively affect it either.
