"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"

"I can't say enough for what Arroyo Bros have done to transform my home. They have done (so far) remodeled a couple of rooms (kitchen and adjoining sunroom) that are absolutely beautiful. Not only that they discovered safety issues with missing support beams and engineered how to support my roof. It was a joy to have them work on my home."

"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."

Shay was knowledgeable and had a lot of experience which is shown on the results and while at the process. The workers were very clean and respectful of our privacy and our home. The kitchen looks great, was done fast and we are very happy!"

Barndominium Builders FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

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.

If you can’t repair and repurpose your shed, it might be possible to sell it, donate it, or salvage parts rather than them just ending up in a landfill. Professional junk removal services will advise you on what can and will be recycled. You may also want to keep some parts to upcycle them for other projects around your home. Turning planks from your memory-filled wooden shed into a coffee table or bed headboard is good for the environment and the soul.
