Result: Total: $2,740.50 | Per door: $456.75 | Materials: $1,590 | Labor: $1,020
Frequently Asked Questions
How much does it cost to replace interior doors on average?
The average cost to replace an interior door ranges from $200 to $650 per door installed, with most homeowners spending around $350 per door. This includes the door slab ($50-$500 depending on material and style), hardware ($15-$150), and professional installation ($100-$200 per door at typical labor rates). Hollow-core doors are the most affordable option at $50-$120 for the slab, while solid wood doors can cost $250-$500 or more. If the door frame needs replacement, add another $50-$150 per opening. A typical home renovation replacing 8-10 interior doors costs between $2,000 and $5,000. Costs vary significantly by region, with urban areas generally having higher labor rates than rural areas.
Should I replace my interior doors myself or hire a professional?
DIY door replacement can save 40-60% of total cost by eliminating labor charges. If you are replacing a door in an existing frame (slab-only swap), it is a moderate DIY project requiring basic tools like a drill, chisel, level, and shims. The main challenges are properly aligning hinges, ensuring the door swings freely, and getting even gaps around the frame. Professional installation is recommended when you need to replace the frame and jamb, when walls are not plumb or square (common in older homes), for pocket doors or barn doors that require hardware tracks, or when you are doing many doors and want consistent quality. Professional installers typically complete one door in 1-2 hours, while a DIYer might take 2-4 hours per door.
What door styles are most popular for modern home interiors?
Shaker-style doors are currently the most popular choice for interior doors, featuring clean lines with a recessed center panel that complements both modern and transitional design styles. They typically cost $65-$300 depending on material. Flat-panel (flush) doors offer the most minimalist aesthetic, popular in contemporary homes, and are the least expensive at $50-$250. French doors with glass panels are popular for offices, dens, and separating living spaces while maintaining light flow, costing $120-$450 per door. Barn doors have surged in popularity for their rustic-modern aesthetic and space-saving sliding mechanism, ranging from $150-$500 plus hardware track costs of $50-$200. Raised-panel doors remain popular in traditional and colonial-style homes.
How does door hardware selection affect total replacement cost and functionality?
Door hardware significantly impacts both cost and the overall feel of your door upgrade. Basic hardware packages ($15-$25) include a standard lever or knob with a simple latch, adequate for closets and utility rooms. Mid-range hardware ($35-$75) offers better finishes like brushed nickel, oil-rubbed bronze, or matte black, with smoother mechanisms and more design options. Premium hardware ($75-$150) features designer knobs or levers from brands like Schlage or Baldwin with high-quality finishes and superior mechanisms. Smart locks ($150-$300) add keypad or smartphone entry for home offices or private rooms. When replacing multiple doors, choosing matching hardware throughout creates visual consistency. Budget approximately 10-15% of your total door replacement budget for hardware to maintain quality proportional to your door selection.
