"We hired MH Construction for a kitchen renovation, and we are thrilled with their work! Mike and his team were excellent from start to finish. Mike kept in regular contact with us throughout the process, answering our questions and working out the design. He and his team were amazingly efficient, often getting more completed each day than we’d anticipated, and they were polite, professional, and always kept the work area clean and safe. They also went the extra mile and conscientiously fixed unexpected issues they found, including several smaller electrical and plumbing glitches. Best of all, we couldn’t be happier with the end product: our kitchen is beautiful and more functional than ever. We’ll recommend MH Construction to all of our friends, and we’d be delighted to hire them again in the future!"

"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, my name is Al Birkenmeier, I am president of Birkenmeier and Sons, Inc.. So grateful for Angie's List and the Super Service Award 11 years in a row. I started my custom building and remodeling company in 1980 after 9 years in the commercial construction industry working with companies like McCarthy Bros., Hercules and Tarlton. I have pursued my love of providing the highest quality of construction while working hard at keeping my overhead down to keep it as affordable as possible. The proof is always in what my past has to offer so please don't hesitate to contact my past clients through a client reference list I would be happy to share with you as 99.9% are not Angie's List Members. Our quality of work and service is second to none so please let us offer you a no cost estimate and opinion for your next custom home or remodeling project. Thank you much, Al Birkenmeier

"Birkenmeier & Sons is really great to work with and the quality of work is excellent. They completely renovated our house 15 years ago and did such a great job. We had a few additional things we wanted to do this year so it was an easy decision to have them cone back out. We really appreciate how easy they are to work with and the attention to detail."

FAQs for addition to existing structure building service projects in Ballwin, MO

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
