"Christian is very conscientious about what he is doing, does a good job and cleans up afterwards. Quite a bit of the work he did was when we were gone so I'd leave him a key. He is very trustworthy."

"We recently had a project from Bilt Rite completed. The owner Mike was very helpful throughout the entire process. Was quoted a 3 week timeframe to complete the project and it was done on time. Even added on a new kitchen floor installation after we signed a contract, still finished on time. It is a process for the entire project but Mike was very helpful throughout. Not pushy either. You will get exactly what you envision for your remodel. Good contractors are hard to find, this is your answer."

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.

Be sure to follow size restrictions, utility separations, and entrance requirements.
