"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."

FAQs for addition to existing structure building service projects in O Fallon, MO
Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take.
Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
