Good Guys did a sunroom for us about six years ago. Looks nice but it's hard to get their attention and almost impossible once their bill is paid. Roof leaked and was leaking into the house roof. They return a small fraction of their phone messages but after several months, they finally did fix it. Worse, years after the build, the city came after me saying the building permit had never been completed and the inspection not done. This was a surprise as getting and satisfying the permit was the builder's responsibility. Still not done and Good Guys is in no hurry.
