The cost of this project will depend on your needs and taste. Hollow core door slabs for outbuildings can cost as little as $25. If you’re replacing an entry door to your residence or if you want a more secure door, solid core door slabs are available with prices starting around $100. Insulated steel and fiberglass door slabs can also be installed in this same manner.
