Interior door replacement is one of the most impactful cosmetic upgrades for a home. Hollow-core doors ($50-$150 each) are budget-friendly but provide no sound insulation. Solid-core doors ($150-$400) block noise and feel substantial. Panel doors with raised or flat panels are the most popular style, while shaker-style doors have dominated interior design trends since 2020.
Installation for interior doors is straightforward when replacing with the same size in an existing frame. A pre-hung door (door + frame assembly) simplifies installation to 1-2 hours per door. Slab-only doors (just the door panel) cost less but require precise hinge mortising and hardware boring, best left to experienced carpenters.
Exterior doors serve three critical functions: security, energy efficiency, and curb appeal. Steel doors provide the highest security rating and lowest cost ($500-$1,500) but dent on impact and conduct heat (low R-value without insulation). Fiberglass doors ($700-$2,500) offer wood-grain aesthetics, excellent insulation, and zero maintenance. Solid wood exterior doors ($800-$3,000+) deliver unmatched beauty but require refinishing every 2-3 years.
When selecting an exterior door, prioritize: ENERGY STAR certification for energy savings, a multi-point locking system for security, and a style that complements your home's architecture. A new front door returns 74% of its cost at resale — one of the highest ROI home improvements available.
French doors consist of two hinged panels that swing open, creating a wide unobstructed opening. They provide excellent ventilation (both panels open fully) and a classic elegant appearance suited to traditional and transitional home styles. In 2026, French doors remain the preferred choice for formal dining rooms, master bedrooms, and luxury patio access.
The cost premium over sliding doors stems from the dual-panel construction, more complex hardware (two sets of hinges, multi-point locks, astragal), and the need for more precise installation. Professional installation takes 4-6 hours and costs $300-$600 in labor. The total project cost including door unit, hardware, and installation ranges from $2,000-$5,000.
Sliding glass doors maximize natural light and views with large unbroken glass panels. They require zero swing clearance, making them ideal for small rooms, decks, and tight patio layouts. Modern sliding doors use low-profile tracks, multi-panel configurations (up to 12 feet wide), and pocket designs where panels slide into the wall cavity.
Standard 6-foot sliding glass doors cost $700-$2,000 for the unit plus $200-$500 for installation. Multi-panel and pocket configurations range from $2,000-$8,000. Sliding doors are generally easier to install than French doors, which makes them cost-effective for both DIY and professional projects.
Interior door installation costs $250-$800 per door. Exterior doors cost $700-$3,000 installed. French doors run $2,000-$5,000. Sliding glass doors cost $1,000-$3,500. Labor accounts for 25-40% of total cost depending on installation complexity.
Interior door: 1-2 hours. Exterior door (same opening): 3-4 hours. Exterior door (new opening or framing changes): 6-8 hours. French or sliding doors: 4-6 hours. Complex installations requiring structural headers take a full day.
Fiberglass offers the best all-around value: energy-efficient, low maintenance, and rot-resistant ($700-$2,500). Steel is the most affordable and secure ($500-$1,500) but dents and conducts heat. Wood is the most beautiful ($800-$3,000+) but requires regular maintenance.
A standard fiberglass front door with sidelights costs $1,500-$3,500 installed. A basic steel entry door costs $700-$1,500. A premium wood door with glass inserts runs $2,000-$5,000+. Add $200-$500 for hardware (handleset, deadbolt, kickplate).
Yes. Old or poorly sealed doors can account for 10-15% of home energy loss. Modern ENERGY STAR certified doors with polyurethane foam cores achieve R-values of 5-7, compared to R-1 for solid wood. Annual energy savings range from $50-$200 per door.
Interior doors need a handle/knob ($15-$50) and hinges ($10-$25). Exterior doors need a handleset ($75-$300), deadbolt ($50-$200), hinges ($15-$40), weatherstripping ($10-$30), and optionally a kickplate ($20-$50) and door viewer ($10-$25).
Pre-hung interior doors are a moderate DIY project (2-3 hours). Exterior doors are advanced DIY due to weatherproofing, security, and structural requirements. Incorrect exterior door installation can cause air leaks, water intrusion, and security vulnerabilities. Professional installation is recommended for exterior doors.
Standard interior doors are 80 inches tall x 24-36 inches wide (30 inches most common). Standard exterior doors are 80 inches tall x 36 inches wide. French doors come in 60-72 inch widths. Sliding glass doors range from 60-144 inches wide.
