Question: how much will it cost to replace my front door?
Answer: Mayer says the price to install a door varies based on hardware, lighting and the amount of glass used. He says the average door install costs $5,000, but if you want a plain, no-frills door it won't cost as much. He says a basic steel door will cost $1,500 and a fiberglass door will range from $2,000 to $2,500.
