"Mike Melia helped us remodel our powder room. He suggested places to buy toilet and faucets and installed those and our new sink, cabinet, light and ceramic tile floor. Price was more than reasonable and Mike’s near obsessive attention to detail really paid off. We get lots of compliments on the work."

"We had a great experience with the Lux Renovations and Owens Corning team. The whole process was very easy from designing the space, selecting colors, and having a contract manager who organized the entire basement remodel including all the trades and inspections. We were sold on the Owens Corning materials for the basement and that they were engineered specifically for a basement space. Would highly recommend this team for your basement remodel needs."

"I worked with Prestige on a few, somewhat unique, projects recently, including renovating an old detached garage and fixing up my basement after a French drain/sump pump install. It was definitely a 5 star experience. Matt seemed more like a partner than a contractorâ ¦he brought creative solutions and ideas to the project, was transparent with updates and showing off milestones as they were completed, and even went the extra mile to ensure quality (example: he insisted that siding be sent back because it did not quite match the rest of the house). He also hooked me up with a custom side door for my EV charger cord that is going to make charging outside so much easier. I will definitely be hitting him / Prestige up again in the future."

"We just had our basement finished. Not re-finished but finished for the first time. The house was built in 1924 with a dirt floor in the basement and low hanging pipes, overall a very challenging job. We wanted to turn it to a family room with a full bath, laundry room, closets, etc. Joe's guys (Chico and Javier) did a fantastic job. They are knowledgeable, thorough, thoughtful, and creative. We would recommend them to anyone without hesitation."

"Cesar and his crew just finished a remodel of my master bathroom. This is the second major project completed in my home by CSZ (prior kitchen remodel) and once again they exceeded my expectations. Cesar worked with me along the way to come up with the perfect design to ensure all my requirements were met. He is knowledgeable and his attention to detail is second to none. The CSZ crew, Armondo and Benjamin were also a pleasure to work with. They are knowledgeable, trustworthy, and hardworking. They also did an exceptional job cleaning up at the end of each work day. My dog even loves them! I highly recommend CSZ Construction. They will most certainly be back for future projects in my home!"

"Great experience with Charles Renovations. We dealt with Angel, who was professional and prompt and honest from start to finish. We are very satisfied with the work done on our basement refinish/remodel. Great communication and great workmanship. I recommend Charles and would use them again."

Basement Remodel FAQs, answered by experts

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%.

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. 

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.

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.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.
