"Jon and his crew were amazing to work with from start to finish! They listened to what I wanted and made my dreams come true. My parents were having a hard time on their own so I finished their basement into a little house for me and my family to be close to them to help and it turned out exactly like I wanted thanks to Jon and his crew. Donâ t hesitate, hire him today! You wonâ t be disappointed."

"Their manager came to the house and he was very helpful and had some ideas on our kitchen remodel. Before he left he said he would have a quote by next week. I got a call from him that following week and said that our kitchen remodel estimate was running in the mid 40â s and thatâ s not touching the pantry. He asked would you like for us to proceed. I said absolutely and I have heard nothing back from them. So my decision to go with another contractor was an easy decision"

Basement Remodel questions, answered by experts

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.
