weeks or months before the job is done. Make sure to ask if any updates need to be made to the bid before starting. Always get it in writing, email or text. Most supply houses will hold there bid prices for 30 days or more. Contractors should not be caught off guard with price increases. Covid was a little weird but that is not normal. A contractor trying to jack up prices last minute is not worth doing business with and is dishonest. Never pay more than the bid!
