We had Golden Bee rebuild our 2nd floor to add a new bedroom, redo the circa 1990 bathrooms, create a laundry room, insulate and correct the poorly built 1950s central heating/air ducting system. The work was on time, at the quality expected and at the price agreed. Necessary changes due to discoveries once they tear down walls (like some asbestos) are dealt with via change orders at reasonable prices. How it works: After your initial requirements you put down a down payment to get to a detailed design where they iterate with you to plan out what the end result should look like, including floor plans and computer drawings, the output being with a full statement of work contract of the agreed work, payment schedule (based on material completion milestones not arbitrary dates). They manage the whole construction project, obtain the permits, all subcontractors, etc. You are brought out to select finish elements, faucets, sinks, cabinets, paint colours etc. with their expert designer there to consult and offer advice. We weren't pressured to pick higher end elements than we wanted. After the work finished they have been prompt at remedying small problems that crop up in any large job including multiple visits back at no charge. I have seen several friends go through reno-hell with construction delays, sketchy contractors playing games, being overbooked, cutting corners and so on, I think we possibly could have paid less but at the cost of the peace of mind and the added stress from common problems with low-cost contractors.
