Door Installation Services

Quartz Countertops. Most Popular

Interior door replacement is one of the most overlooked upgrades that makes a dramatic difference in a home. New interior doors — especially a consistent set in a modern style — make older homes feel completely updated. We install pre-hung interior doors (frame and all), pocket doors, barn doors, and French doors. We also install door hardware: knobs, lever handles, deadbolts, and hinges. Common upgrade: replacing hollow-core builder-grade doors with solid-core wood doors for better sound dampening and a quality feel.

Exterior Door Replacement

An exterior door upgrade improves curb appeal, security, and energy efficiency in one project. We replace front entry doors, side entry doors, and back doors. Options include fiberglass (most popular durable, insulating, can be painted or stained), steel (most secure, lowest maintenance), and wood (traditional look, requires maintenance). We handle the full installation including weatherstripping, threshold, and lockset installation.
