"Granzow Home Inprovement was amazing, from the initial meeting, to questions or concerns we had, before, during, and after the work was performed. We were pleasantly surprised mostly by the care and concern Rick and Bob took regarding their customer, which is rare in many businesses. This was our first home remodel project, we learned a lot from it, and we love our basement! Keep up the excellent service!"

"I hired GR General Contracting to remodel my basement. Every aspect of the project was excellent. My remodeled basement is beautiful. I would definitely hire again. Gordon communicated regularly about the project schedule and kept me up to date every step of the way. The crew were outstanding and it was a pleasure to have them working in my my home. At the end of every day I received a walk through of the progress and an overview of the next days work. I am thoroughly impressed with my experience working with GR General Contracting."

"I am so grateful to have had such an excellent contractor. A basement remodel in a 1920s home is always going to have surprises and puzzles to solve. Mike took on the challenge, made awkward spaces more comfortable, and added a bathroom where there was none. He communicated carefully every step of the way, and offered options and great suggestions. His tile work is beautiful and he pays attention to details. I wholeheartedly recommend Mike."

"Overall good job with finishing my basement. i really like my basement overall after i installed carpet from Home Depot and home-theater system from Best Buy. i really appreciated them picking up the selections for the basement bathroom from Home Depot. Things that could have been done better: * I had to replace the closet fixtures, probably because they were fixed on the dry wall. * would have been better if i had choice with the shower inside the basement bathroom."

"Shawn took our basement from completely unfinished to a 1400 sqft luxury space. We had an incredible experience with Shawn and his team. Shawn was very flexible with us where we needed flexibility and was reliable! It was obvious that he wanted us to be happy with the finished product and listened to what we wanted. Communication was great! I would hire him again in a heartbeat!"

Basement Remodel FAQs, answered by experts

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.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

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%.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.
