"Solid Rock Homes & Design worked with us to design and build a kitchen in our basement. They worked within our budget and time frame to complete the exact kitchen that we desired. They were professional and knowledgeable in all stages of the project- from the detailed design of the space, to the plumbing and electrical work, then the installation of the cabinets. We highly recommend any homeowner to use them for any renovations!"

"The HomePro Remodelers, with their exceptional skills, helped make our project a huge success. They took extraordinary effort in cleaning up and were very considerate of our surroundings. Since our back porch enclosure has added so much to our lives, we are considering having our front porch also enclosed."

"We enthusiastically recommend TMMAX Custom Interiors - this is definitely a business that needs to be on the map for our local members. Professional from end to end. What started as a basement needing the local "Pittsburgh potty", we needed to expand our family by finishing the whole basement. We appreciate attention to detail. We continued to have excellent collaboration, communication, and input throughout the project ensuring we were all envisioning our custom basement dream. We are thrilled from head to toe with exceeding our expectations and appreciate the basement renovation project on time and on budget. The outcome was much larger than we ever expected. The floor plan vision allowed us to personalize for elderly and practicality for years to come. We were given multiple options. Having the ability to custom each section of the basement for our needs finished without a hitch. Hands down a company to be added to your project selection for your basement or any interior need.

"We couldn’t be happier with the work Chad did on our basement renovation. From start to finish, he demonstrated exceptional quality, reliability, and professionalism. What impressed us most was his willingness to listen to our ideas and work closely with us to bring our vision to life. He was always open to adjustments and found creative ways to accommodate our needs and budget without compromising the quality of the final result. The craftsmanship and attention to detail throughout the project were truly impeccable. Every aspect of the work was completed to a very high standard, and it is clear that he takes great pride in what he does. His team was skilled, respectful, and professional, and his close supervision of every phase of the project ensured that everything was done right. Beyond his technical expertise, his kindness, honesty, and genuine care for his clients stand out. He was always available to answer questions, address concerns, and make sure we were completely satisfied."

"We had a great experience. Steve listened to what we wanted and made suggestions too. They treated the job as if it were their own home. The result was exactly what we wanted-beautiful work. They even designed built custom radiator covers. They came in under budget and within the promised timeframe. We have already talked to them about coming back to do our deck."

Basement Remodel FAQs, answered by experts

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.

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.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
