"I signed up on Angies list on 2/18/2017 and had the work done today. Tooltime got back to me on 2/21/2017 and we made arrangements to have the work done today. Mike from Tooltime was here at 9AM on the dot, he put the safety bars in and left the bathroom cleaner then it started. I will call on Tooltime again for more work in my home. If there were more stars to be awarded I would do that. Thank you Ivka"

"Josh did a great job on my roofing repair! He showed up when he said he would, and the roof looks great! He also installed some replacement skylights and siding. He sent many pics of the job as I wasn’t able to be there when the work was performed. I will definitely use him again."

"Having faced a leaky roof crisis during heavy rains last year, our decision to reach out to this builder turned out to be one of the best choices we made. I wholeheartedly recommend them for their exceptional service. Faced with the challenge of addressing a complex roofing issue involving both flat and slanted structures, they demonstrated unparalleled expertise. Throughout the process, their meticulous attention to detail stood out. From coordinating with skilled roofers to connecting us with a superb cabinet maker, every step was executed with precision. What truly set them apart was their commitment to effective communication, ensuring minimal disruption to our family's routine during the project. Their dedication to not just resolving the issues but doing so with a focus on quality and customer satisfaction was evident. Even during the insurance proceedings, they navigated the complexities effortlessly, making the entire experience stress-free. This builder is more than a construction service; they are a reliable partner who delivers results with an unwavering commitment to excellence."

The kitchen looks great, was done fast and we are very happy!"

Barndominium Builders FAQs, answered by experts

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.

Technically, most states allow tiny homes, but it depends on the definition of tiny and whether the structure is permanent. Zoning laws regarding home size and construction are significant factors. For instance, a tiny home may be legal as a recreational vehicle in most areas, but you may only install it on a property if it complies with building and zoning codes.

Average barndominiums last between 50 and 150 years depending on the materials they are made from, how well they are maintained, and the environment they are built in. Barndominiums are very durable and have a much longer lifespan than traditional wood homes. With proper care and maintenance, well-built barndominium homes can last generations. 

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.

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.
