    How do I know when it's time to replace my front door?

    Common signs that your front door may need replacement include cold drafts, difficulty opening or closing, visible warping, rust, moisture damage, and worn-out weatherstripping. A door that no longer closes or locks securely can also become a safety concern. Replacing an aging exterior door can improve comfort, security, and curb appeal while reducing maintenance problems.

    Both fiberglass and steel entry doors can perform well in Wisconsin’s climate. Fiberglass doors offer excellent durability, low maintenance, and realistic woodgrain finishes without the upkeep of natural wood. Steel doors provide strength, security, and good energy efficiency, often at a more affordable price. Bob’s offers ProVia and Albany entry doors and can help homeowners compare materials based on appearance, performance, and budget.

    Replacing an older, drafty exterior door with a properly installed, energy-efficient door can help reduce unwanted air leakage and improve indoor comfort. Modern insulated doors, quality weatherstripping, and proper installation help limit heat loss during Wisconsin winters. Actual energy savings depend on your existing door, home insulation, and other factors. Bob’s offers energy-efficient entry door options designed to improve comfort and weather protection.
