"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."

"I hired Sage Homes to transform my basement into a gaming area, wet bar, guest room, and bathroom. The project was completed on time and within budget, which was a huge relief. Christi was excellent at communicating throughout the entire process. The crew was professional and cleaned up after themselves. I'm very happy with the quality of the work and the finished basement is a cozy addition to our home. I would highly recommend Sage Homes to anyone looking for a basement remodel!"

"I hired Karsten for a full bathroom remodel. He gutted out old tub, tile, fixtures and counter. I had him install an arched shower floor to ceiling with a shelf and entirely new fixtures. He did the framing, plumbing, tile, and painting for the bathroom making it entirely custom. I’m very happy with the bathroom and the professionalism of Karsten and his team. Thank you !"

"Very pleased with Mile High Remodeling. They did a great job remodeling my main bathroom which included removal of the old jacuzzi tub, replacing it with a freestanding tub, new tile, lighting, paint and stain, as well as plumbing and electrical work. Luis and Lucero and their team were very professional, personable and committed to excellent customer service. Their daily communication about the project, suggestions and help with design were all much appreciated. The cost was reasonable and fair. I highly recommend Mile High Remodeling."

Basement Remodel FAQs, answered by experts

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
