"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

"Mike replaced 9 double hung windows in my home with Andersen replacement windows. The quality of work was excellent and the price was very competitive. Mike is very professional and was a pleasure to do business with. He returned my calls immediately, showed up on time, provided a written estimate, and patiently answered all of my endless questions. I highly recommend Hammer Time Contracting and will be hiring them again for future home improvement projects."

"The folks at Daddona were very professional and excellent to work with. My wife and I were very satisfied with the job they did. The basic build was actually completed a bit ahead of schedule and any minor issues thereafter were taken care of without a problem. I would certainly use them again and would be happy to recommend them to anyone else that has a need for the services they offer. Stan and Dawn"

"I needed to have the old flooring removed and the new flooring put down. They team was very professional. They realized the subflooring was messed up in a section and made sure to stop and communicate so the job can be doone correctly. I appreciated that factor and was able to approve a replacement of the messed up board the great thing was they were still able to finish the job in the time frame they originally stated! I plan to use them for all jobs moving forward. Priced fair,quality work, and friendly and professional!"

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.

A simple A-frame chicken coop can take as little as three hours to build, but a more substantial all-in-one coop to house a large flock can take four or five days to build. Consult a local handyperson or custom coop builder for a time estimate based on the specific details of your project.

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.

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

Whether pole barn posts should be set in concrete depends on the soil surrounding your home. If your soil is compact and digging conditions are agreeable, then setting pole barn posts in concrete is an ideal option.
