Frequently asked questions
How much does door installation cost?
Door installation costs $150–$1,500+ depending on door type. Interior door installation runs $150–$400 including labor. Exterior door installation costs $500–$2,500 due to weatherproofing, security requirements, and more complex framing. Front entry doors cost $800–$5,000+ installed.
How long does it take to install a door?
A pre-hung interior door takes 2–4 hours to install. An exterior door replacement takes 4–8 hours. New rough opening framing adds 2–4 hours. A full entry door with sidelights can take 6–12 hours. Most single-door projects are completed in one day.
What is a pre-hung door vs. a slab door?
A pre-hung door comes with the frame, hinges, and sometimes hardware already attached — easier and faster to install, especially for new openings. A slab door is just the door panel without frame — cheaper but requires an existing, in-good-condition frame to fit into. Pre-hung is recommended for exterior doors.
Can I install a door myself?
An experienced DIYer can install an interior slab door replacement in an existing frame in 2–3 hours, saving $100–$250. Exterior doors require precise weatherproofing and plumb installation — mistakes lead to drafts, water intrusion, and security issues. Pre-hung exterior doors are best left to professionals.
What type of door is most energy-efficient?
Fiberglass doors are the most energy-efficient — they have the highest R-value (R-5 to R-6), don't warp or rust, and can mimic wood grain. Steel doors with foam core are a close second (R-5 to R-7) and are more affordable. Solid wood has lower R-value (R-2 to R-3) and can warp with moisture.
Does replacing an exterior door increase home value?
Yes — front door replacement returns 65–75% of its cost in added home value. A new steel entry door at $500–$2,000 installed is one of the most cost-effective curb appeal improvements available.
