"My experience with this company has been amazing! My home was damaged by a fierce tornado and I wasn't even sure they could restore it. They did that and then some! They're reliable, timely, efficient and do great quality work. My home has been restored and it's even better than it was before. Highly recommend! In a day where it's hard to find great help and reliability at a fair price, you'll find the best in B and J contractors."

"As a first time home buyer, I was already facing a new and stressful situation all by myself. I was aware when I purchased the home it would require work prior to moving in. I sent request to multiple handyman and larger companies to obtain a quote and estimation of time for being able to complete what I need to be able to move in, and then the remaining work. I received quote and estimate on time from this company faster and prompter than any of the other companies I submitted too. After receiving a quote, they came out to my home after scheduling a time frame. They arrived and followed me through the house, paying attention to the details I requested, took notes on everything I was wanting and requesting, and Kareem was able to understand exactly what I needed done. I asked Kareem and his company to run and replace the wiring in the kitchen, the wiring was so old it was at danger of arching and catching fire, and I needed the basement to be waterproofed by installing a sub pump and the entire drainage and pipe system. I informed Kareem I had to have all of this completed within three days, I had to be moving in on the Fourth day, not only did he complete it within the time frame, he completed on the second day by noon, giving me extra time to move in. I was more than happy with this of course, however, as to rewiring of my kitchen he was able to place plugs above the counter tops in very convenient places for me, making life easier. As to waterproofing my basement, the completed work looks amazing, and I am unable to tell that the concrete floors had been ripped open, and was done perfectly. I would highly recommend Kareem and his Company any day and to any of my friends and or family."

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.

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.

Due to the expansion of the tiny house movement, you can usually find tiny houses to buy in your state. Prices range considerably based on size, style, and type. If you’re looking for a tiny home that’s move-in ready, you may be able to find a good deal to buy or a prefab dealer near you. 

It is recommended that you check with your local building official on barn building requirements and rules, since size restrictions vary greatly from region to region based on what your property is zoned for. Some cities limit barn construction depending on if your property is residential or commercial. The three main factors your building commission will evaluate are:

  • Height and lot coverage: How tall your barn is and how much of your total property it occupies

  • Setback: Distance between barn and property line

  • Easement: Legal right for another owner to access another’s property

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.
