"I contacted multiple contractors when I was looking to remodel my house. Payton responded to my inquiries in a timely fashion, was willing to work with my work schedule, and communicate via email and text. He was able to offer ideas and options when I wasn't sure which way I wanted to go with a project, and has made this remodel go smoother than I expected. I would recommend Pine Top Finish Co. and will be contacting Payton again when I'm ready for the next big project."

Mike also has a great network of talented tradesman. Thank you, Mike! We LOVE our new home!!!"

"After my basement flooded, I was in need of a good flooring installer to finish out my basement. Aaron (the owner) came highly recommended from a work colleague. I am very happy with the work. Great price, and he was in and out in two days! Couldn't ask for better contractor!"

"Dylan was the GC for an ADU that I had built on my property. He was very professional and built the whole ADU faster than anticipated. The quality of his tradesmen is excellent. He is friendly and has excellent communication skills. We would nightly recommend Dylan for any construction project big or small."

"would recommend Remedy Residential to anyone and everyone. We are absolutely thrilled with the remodel Eric did for us as well as with how great it was to work with him. His skill set is immense along with his knowledge about old homes and new. In our case, our house in North Boise was built lathe and plaster in the 1930s. He knew exactly how to handle it and everything that comes along with working on it. He maintains good communication, has great recommendations and in general is an all around great guy. We appreciate all the work he did, all the sub contractors that he managed and for how well he kept everyone accountable. I will undoubtedly reach out to him again for our next project."

Basement Remodel questions, answered by experts

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

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.

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.

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%.
