"Jordon and Cam were awesome to work with and our new basement is amazing. We had never hired a contractor before so we were nervous about hiring someone. Wright Brothers took the time to answer all questions, and we had a lot of questions. There communication during the job was great and our new basement exceeded our expectation. The initial price they quoted was exactly what we paid, with the exception of a few upgrades we requested after the project had started. We have already referred several of our friends to them and cannot say enough good things about them."

"The Basement Company North finished our basement and added a fireplace in our home. The team always kept us notified on the schedule and kept a very clean worksite even with all the construction. They were always quick to respond to our questions and we love the finished work they did. We would definitely recommend The Basement Company North and will be using them on additional house projects down the road."

"Laguna Construction finished my basement and made the process as easy as possible. He added on a room and a beautiful bathroom. I have not taken on home projects this big before but I am glad I had Daniel on my side for the task. Reasons to choose Daniel: -Daniel's bid was very competitive with other bids. He is very fair and accurately estimated the costs - The communication that Daniel offers is unmatched. I travel for work and I could not have been more comfortable with him getting everything done while I was gone -It is clear Daniel takes pride in his work. He knew I was on a tight budget but still over delivered in quality -The time frame that everything was done is impressive. Daniel is motivated to finish projects quickly. I can easily say that the only thing that slowed him down was my decision making While I had many doubts going into this project I am very happy with the outcome and every step it took to get there. Daniel has great reviews for a reason. I am looking forward to using Daniel in the future and have even recommended him to my family! Thanks Daniel for all you do!"

"I couldn't be happier with my bathroom remodel! From the very beginning, the team made the whole process easy and stress-free. They took the time to listen to what I wanted, answered all my questions, and kept me updated every step of the way. The attention to detail was incredible, and the finished bathroom turned out even better than I imagined. The tile work, fixtures, and overall craftsmanship are beautiful. The crew was always on time, respectful, and made sure everything was cleaned up at the end of each day. What was once an outdated bathroom is now one of my favorite rooms in the house. I genuinely enjoy spending time in it, and I've received so many compliments from family and friends. I highly recommend them to anyone looking for quality work and a team that truly cares about their customers."

"Emilio and his team did a fantastic job scraping out popcorn ceilings, retexturing them, and painting them all throughout the house and garage. When the paint started to crack in a couple places, he immediately came back and refinished the area until it was perfect. Emilio is also very responsive via text and takes pride in his work. We would highly recommend Drywall 614 for any project"

"My basement is almost finished and the project has gone really well. It has been a great combination of letting me pick items out and then their excellent installation of everything just the way a professional would do it. We are really happy with the result and our PM Travis has been really communicative and great to work with."

Basement Remodel FAQs, answered by experts

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

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?

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
