"We hired Wright Brothers to do our basement remodel that included a full bar, guest bedroom, bathroom, and a lot of custom millwork (i.e built in entertainment center, wainscoting, base trim and window casing). Although we had a design in mind before we hired Wright Brothers, they were able to offer suggestions to improve what we had already started. Their prices were very fair and the communication from the beginning to the end of the project was outstanding. We never felt pressured to do anything and they were always upfront and transparent when items outside the scope of work were identified. Guests are constantly amazed when they walk in our basement and see the before and after pictures. It is a place our family will use for many years to come thanks to the quality, dependability and integrity Cameron and Jordan put into their jobs."

"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 was talking with 3 contractors via text for quotes and descriptions, and the amount of detail that he had in his replies, it was easy to choose him for the job. He didn’t try talking me into more parts than were needed, and was able to reuse my existing door and also install the screen/glass door without extensive modifications."

"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 !"

"We hired Collis Renovations for our basement remodel project, and we are very happy with the quality of work, reliability, and overall experience. Collis Renovations is a top-notch company. Daniel, the owner, has excellent character and is no ordinary contractor. He holds an engineering degree and even took time out to be interviewed by my son for a school project who is in the Engineering program at CU Boulder. Thanks for everything Daniel!"

Basement Remodel FAQs, answered by experts

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
