Converting a carport to a garage typically is less expensive than having a contractor build a new garage—provided the carport’s slab, support posts, and roof are in good shape. On average, expect to pay $9,000 to $11,000 for labor costs alone to have a carpenter finish off the walls and install doors. When these costs are added to framing lumber, siding materials, windows, a garage door, and an entry door, plus electrical service upgrades, permits, and dumpster fees, total costs range from $18,000 to $35,000 for a professional installation. A good DIYer may be able to cut these costs in half, but it is always best to have a professional install the garage door itself. Under the right circumstances, a carport can successfully be converted to an enclosed garage, but there are many issues to consider before you solicit bids or decide to tackle such a project yourself.
