"We needed the playroom in the basement to be refreshed: new floor, windows and paint. We also added a custom closet and had the central AC ducts encased. We had already hired BAS Construction a few years ago to finish part of the basement, and wanted the playroom to match. We were again very pleased with the results. The various crews showed up on time and the work site was kept clean. The work was completed within the promised time frame. Ali and Sina were easy to work with and very professional, from planning the project to completion. They came up with great suggestions. We would highly recommend hiring them."

"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."

"The team at Dynamic Design & Remodeling were superb. I hired them to do our basement and could not be happier with the result. Great craftsmanship, on budget, and on time. I'll definitely be using Justin and team for our next renovation."

"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."

"Lilco was a great company to work with! They are easy to communicate with and answered all of my questions and concerns. They are reliable and trustworthy. My kitchen and bathroom came out better than I could have imagined. I couldn’t be happier and hope to be able to remodel my other bathroom in the near future."

"I have no skills or vision when it comes to construction, so there was no way I was going to attempt any part or function to finish my basement myself. There is so much involved with finishing a basement that the actual thought of getting it done was exhausting! John and his team made the large task to finish a basement easy! John has the skillsets to do the work and orchestrate different contractors with various skillsets to get each phase of the construction done. Proworks Interiors is very professional and know what they are doing. It was a great relief that they were able to make something that seemed impossible, possible in a matter of a few months."

"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!"

"From the very first contact phone call...till the completion of the job....Michael and his crew were the best. Having french drains installed in your basement is far from a glamorous remodel but NPW handled the job as if they were "doing" your kitchen! Fair price...great job and professional follow-up. So pleased"

"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

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
