"Our basement had an odd layout and we were not sure how we could make it a livable space. We also had a realistic budget as we are both working individuals with a family, trying to expand our home, within our personal means. Jolanta and her entire crew over exceeded our expectations. Every detail was completed meticulously. Everyone worked so hard and was so kind. We made modifications as the project progressed as we could see new visions and we were able to have input. It was a great partnership and the quality of the work is beyond our expectations. Highly recommend. Of note, I found Excellent remodeling on Angie’s list after receiving multiple bids I was not comfortable with and almost gave up on the project. Jolanta came out right away and her ideas, comfort level made me trust her. I am so thankful and could not have made a better decision. Thank you."

Basement Remodel questions, answered by experts

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

Save money on your basement finishing project by making cost-effective decisions such as minimizing structural changes and avoiding costly construction revisions. DIY simpler tasks such as painting or basic cleanup to reduce labor costs. You can also opt for energy-efficient fixtures and materials that may qualify for rebates or tax incentives.

Envision the type of bar experience you'd like to create for your guests. For example:

  • Does your basement have enough finished space for bar stools or seating?

  • What type of additional lighting would set the tone for the room?

  • Are there basement windows or an HVAC system?

  • Do you need new plumbing in your basement for a proper wet bar?

  • Could you be happy with a built-in wall cabinet bar rather than a full-scale wet bar?

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
