"Randy and his team did a great job finishing our basement in a short time. Along with finishing the basement, they took care of moving a drainage hole to save some space, replacing old basement windows, setting up kitchenette and a full bath with good quality products and work. They made sure we were satisfied with every piece of work and to do that they go above and beyond. We felt reassured when Randy's son says 'no biggie' to make any changes as we wanted. He can custom build almost anything, my son & his friends loved the hideout they built understairs. Whole team handled all work with great care and made us feel comfortable with all construction work around our newborn baby home. We definitely recommend them to our friends & family."

Hello there! I'm a Saint Charles/Saint Louis native and an experienced carpenter and remodeller of 17 years! Been in my own business since 2022. I love to do beautiful work at reasonable prices. I am focused on design-minded small construction and carpentry--this means that I am not primarily so focused on flashy features and the newest updates, and more focused on how I can create a project with you that makes sense with your specific house and it's architectural design. I love working with wood the most but really love doing most anything on a home and happy to do handyman work here and there as well. Please reach out so we can start a conversation! I'm happy to offer advice on how to navigate the construction industry or send you phone numbers of other great guys if you need other services. I focus on approachability and a down to earth experience. I love doing good work, i'm easy to deal with and show up when I say I will. Would love to work with you!

"Great customer service they arrived on SAID time ON time. They didn't leave until the job was completed. I spotted one small flaw but nothing to complain about other than that they did a great job. They cleaned up behind themselves. I had to disposed of all the trash myself but they did put all the trash in bags and sat them outside nice and neat and it was also in the contract that the customer is responsible for disposal of trash. It was not a surprise. This properly why the cost was reasonably priced. I will use them again."

Basement Remodel FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

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%.
