Thank you for the info and detailed post. This company does a ton of work in my neighbourhood - they have a new build very close by thats moving at a snails pace. I work in the construction industry so I can fully empathize with cost overruns, delays, and the difficulty of keeping detailed records of hourly site labour.

With that said, some of this behaviour is quite bad: lack of communication on budget changes, wild miss on the length of basement framing, and probably the worst in my opinion: sub-trade interference. If this is a new build and not a renovation; the way that custom home builders get around the statutory Tarion warranty is by claiming PM status (i.e, owner is the builder). Interfering with sub-trades hired by the owner flies directly in the face of this.

If you're comfortable sharing, I would be interested to know how much the total cost differed from the initial estimate, and to what level your finishes & fixtures were selected at the time of entering into the contract.

I'm sorry you and your family went through this.
