"We hired Master Remodel & Construction after our master bathroom, kitchen and garage suffered major water damage after an interior flood caused by an overflowing toilet. Brian Inkley (owner) and Jacob Quick (project manager) have a team of dedicated, talented professionals. They did a superb job in restoring our damaged house. They are a busy team of workers who kept us appraised of their availability for the various stages of our restoration. For the repairs that they didn't do themselves they had excellent recommendations for the professionals we needed such as the carpet installation, closet system installation, kitchen cabinets and the refinishing of our hardwood floors. They seem to be in demand, working at several projects at the same time but we always felt that we were their top priority. Jacob worked with our homeowners insurance adjuster to be sure that the funds allocated for our losses were enough to complete our projects. We recommend Master Remodel & Construction with pleasure."

"Dana King DB&R is a fun company to work with. We are now on our third project with them. 2 bathroom remodels and now we are in the middle of remodeling a hearth room and a dining room. I love the results we have had in the past. Very good design work, creative solutions, quality products and workmanship. The designers, managers, staff and trades people you work with are all very approachable and down to earth. Your final price will not be inexpensive but you will get what you want and that is important. If something isn’t quite right at first, they will fix it. My 1970s house is getting prettier, updated and more useable thanks to Dana King and her great group. They are also very good at understanding “age in place” meaning that your house can evolve and be better equipped to work for you as you age. We want to stay in our house a long time. I definitely do recommend Dana King Design Build and Remodel."

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!

"After absolutely destroying my bathroom thinking oh a renovations easy… I found Mason and he made it better than I could’ve imagined. He did the bathroom top to bottom! Drywall, bathtub, toilet, tile on the walls and the floor, the vanity installation and the light fixture! He even put the mirror and shelves up for me! Ended up having him renovate my laundry room (which was also a full gut and redo). Told him what I wanted and he made it happen! Custom shelves and cabinet! Already have him hired to do my kitchen!! Definitely recommend using this company for your renovations."

"From the beginning of my project in January 2024, I have never regretted my decision to choose Ethos Building Group LLc. Jeh Johnson and his partner Tracy Herod have worked diligently to execute the itemized proposal that began this project to rehab, restore, and rebuild my home at 607 Wilmington ave. St. Louis MO 63111. An incredible number of tradesmen and tradeswomen have done their individual tasks all on a schedule professionally overseen by Jeh. These liscensed and masters of their trades worked alongside Jeh who if necessary stepped in and aided e these individuals. His overall expertise has brought my home to this point. One must keep in mind that a burnout like my home is an unusal job for Ethos Buildig Group LLc to accept. Yet at every stage my home has been given the same careful and thorough attention as their larger jobs. And despite some push back with my insurance company every thing has proceeded smoothly and orderly manner given the inevitable supply chain delays. Jeh Johnson is an affable young man who has facilitated all phases my prject and has even taken time to educate me on all the intricacies involved in a project such as mine. I cannot think of any single word to describe my experience with Ethos Building Group LLc but the forgoing will have to suffice. Thanks you for your kind attention. Stay safe and make a point of telling those who you find dear just what they mean to you."

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.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
