"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."

"Jose did a great job. There was light freezing rain on the day the job was schedule and surprised Jose didn't cancel. He showed up, setup his equipment and worked 3 plus hours going around the home washing away built up mildew on the siding. He even got on the roof to wash the dormers' siding and cleaned out the gutters."

"The chimney work took two days (less than I thought) and he did a great job in our price range!  I was impressed that he gave us several options on what could be done.  He worked fast (I wish I had half his energy) and knew what he was doing.  He was respectful of my time and showed up within minutes of when he said he would, got to work and stayed with it to get as much done during the day as he could.  The chimney looks great and I'm very satisfied with his work.  I have hired him again to do some plumbing work for me and was totally satisfied with that job as well.  I would recommend him for any work around the house that you may have - he's definitely worth the call.

Barndominium Builders FAQs, answered by experts

It is almost always more affordable to buy an existing home than to build a new one. Building a home involves numerous costs, including labor, permits, inspections, utility hookups, and brand-new materials, finishes, and appliances. Additionally, new construction loans can have higher interest rates than traditional mortgages, and property taxes on new homes are often higher, increasing long-term costs. An exception is a DIY house build, which can be cheaper than buying an existing home if you do the labor yourself. While building is generally more expensive, a new custom home offers complete control over the layout and design. Furthermore, new construction is typically worth more than a comparable pre-owned home and may provide a better return on investment if sold quickly.

Depending on your needs, you may find a storebought pole barn is a much less expensive option than a custom-built one. You can find pole barn kits from big box retailers starting at $11,000, but you will be limited when it comes to size and add-on features. As long as you have the necessary skills, you can save on labor costs by doing it yourself; but there are a lot of different skill sets you would need, and mistakes during the building process can lead to excessive repair bills later.

The most significant expense when building a barndominium is constructing the metal shell, which includes the roof, doors, and windows. Additional exterior components impacting the overall cost include metal siding and the concrete foundation.

It’s much less expensive to build a house with wood. This is because wood is relatively inexpensive, strong enough to endure decades or even centuries of weathering and pressure, and is easier to replace if there are issues. The cost of stone houses are incredibly expensive, heavy, time-consuming to build, and difficult to repair. 

The difference between a pole barn and a stick-built barn is in the construction. Large poles in the ground provide support for pole barns. For stick-built barns, 2-by-4 or 2-by-6 lumber (known as sticks) create a frame around load-bearing beams. Stick-built construction is far more popular for residential homes. Pole barns are more cost-effective because they require fewer materials and less labor.
