"Power 2 Construction & Remodeling nailed our full basement remodel and the finished project is exactly what we envisioned. Randy was always available to talk, consult on our vision, and kept us up to date on the entire process. Fully satisfied with price, quality, and the timeline it took. We would use them again for any future projects. It is hard to trust someone with such a big project but you won’t go wrong hiring Power 2 Construction & Remodeling for your next job!"

"What can I say about Rick, Eric and their crew. They preformed an incredible job on our kitchen remodel. They were prompt, always on time answered all our questions and concerns. The work they preformed was outstanding and very professional. We plan on doing a bathroom remodel in the near future and Premium 1 Properties will be our go to contractor. I highly recommend them for any and all contracting projects. Thank you Rick & Eric for the awesome work you did on our kitchen!"

"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."

"Weaver did very well with our basement finishing. They did get the way we wanted things done, which was a bit unique, but they did miss a few things, like not understand we were going to take care of some things that were non-standard ourselves (because they were non-standard.). They also did leave us hanging a little at the end - we still never got our light switch at the end of the stairs hooked back up to the light, nor found out how to change the cam lights, but at some point I just gave up, cause they were kinda done with us after they got their last payment. Generally good to work with, they did have a bit of a time getting workers due to COVID, and there were some small less than desirable messes left. But thatâ  s small compared to the overall work, which was good. So Iâ  m pretty happy overall."

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!

Customers say: True professional

"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."

FAQs for basement remodeling projects in Portage-des-sioux, MO

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
