The difference between interior and exterior door replacement is significant, as each type of door serves a different purpose and has unique requirements for installation and maintenance.

Interior doors are used to separate rooms within a building and are typically made from lighter materials such as wood or composite. They do not need to provide as much insulation or security as exterior doors, so they can be less expensive and easier to install. Interior doors can come in a variety of styles and designs to match the decor of a home or office.

Exterior doors, on the other hand, are the primary entry and exit point for a building and are designed to provide security, insulation, and protection from the elements. They are typically made from more durable materials such as steel or fiberglass and may have additional features such as weather stripping, locks, and deadbolts. Exterior doors can be more expensive and require a more complex installation process to ensure a proper fit and function.

When it comes to replacement, interior doors are generally easier to replace since they are lighter and require less complex installation. In most cases, you can replace an interior door with a similar-sized one without making any major adjustments to the door frame. Exterior doors, on the other hand, require more careful measurements and adjustments to the frame to ensure a proper fit and function. It's also important to consider factors such as weatherproofing and insulation when selecting an exterior door to ensure that it provides adequate protection and energy efficiency.
