Masonite door prices typically range from $80 to $700 for the door alone, while a professionally installed interior door often totals $250-$1,000. The final cost depends on door size, hollow-core or solid-core construction, glass, finish, hardware, labor, and whether the existing frame needs work.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Interior Masonite door slab | $80 | $220 | $700 | Door only; style and core affect price |
| Prehung interior door | $150 | $350 | $900 | Door mounted in a frame |
| Installed interior door | $250 | $550 | $1,200 | Standard opening and basic trim |
| Exterior Masonite door | $300 | $800 | $2,000 | Door-only prices vary by insulation and glass |
| Installed exterior door | $700 | $1,500 | $3,500 | May include frame, weatherproofing, and disposal |
Masonite door prices by type and installation scope
Masonite makes interior and exterior doors in several styles and construction levels. A basic molded hollow-core interior slab commonly costs $80-$200; a solid-core molded door is often $180-$450. Decorative panels, glass inserts, special dimensions, and factory finishing can push the door price to $700 or more.
A prehung interior unit, which includes the door attached to a frame, generally costs $150-$900 before installation. A standard interior replacement with ordinary access and no major frame repair commonly runs $250-$1,000 installed. A complicated opening, custom size, or premium finish can raise the total beyond that range.
Exterior Masonite options have a wider spread because insulation, weather resistance, glass, and security hardware matter. A basic exterior door may cost $300-$900 for the unit; upgraded designs commonly reach $1,200-$2,000. Installation can bring a typical exterior replacement to $700-$3,500, particularly when the threshold, jamb, trim, or flashing needs replacement.
For a standard interior replacement, a practical budget is about $350-$700 installed. Assumptions: U.S. average labor, standard 30-by-80-inch opening, midrange door, and no structural repairs.
What a Masonite door quote includes for materials and labor
Quotes differ in whether they cover only the door or a complete operating assembly. A slab is the door panel alone; it may need trimming, hinge mortises, and hardware preparation. A prehung unit includes a frame but still requires fitting, shimming, fastening, casing, and sometimes painting.
| Quote component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Interior door slab | $80-$700 | Per door | Core, panel design, glass, size, finish |
| Prehung frame and unit | $150-$900 | Per opening | Jamb depth, material, handing, trim package |
| Installation labor | $150-$450 | Per interior door | Fit, leveling, hardware, casing work |
| Hardware and accessories | $25-$250 | Per opening | Knob or lever, hinges, privacy lock, quality |
| Removal and disposal | $30-$150 | Per door | Old frame removal and local disposal charges |
| Painting and finishing | $75-$300 | Per door | Prep, number of coats, finish type |
Labor for a straightforward interior installation often falls around $150-$450 per door. A contractor may charge a minimum service fee of $100-$250, so replacing just one door can have a higher labor cost per unit than a multi-door project.
Exterior installation labor is commonly $300-$900, before the door and larger repairs. Quotes may also include flashing, insulation, caulk, threshold adjustment, and weatherstripping. Confirm whether painting, interior casing, exterior trim, and disposal are included rather than assuming they are part of the base price.
Compare like-for-like quotes by checking whether each price covers the frame, hardware, finish, and disposal. Assumptions: Typical contractor pricing; material selections and local labor rates vary.
How size, core, glass, and frame condition change the price
Door dimensions and construction have a direct effect on the bill. A common 30-by-80-inch interior door is usually less expensive than a 36-by-96-inch unit. Nonstandard widths, heights, or thicknesses may require a special order, often adding $50-$250 or more and extending delivery time.
Hollow-core doors are generally the lowest-cost choice and are lighter to handle, but they provide less sound control and impact resistance. Solid-core options often add $100-$300 per door compared with similar hollow-core styles. They are heavier, so fitting and hinge requirements can add labor if the existing frame or hardware is not suitable.
Glass increases the material price and can add handling or installation complexity. A simple glazed interior door may cost $100-$400 more than a similar panel door; larger decorative glass or privacy glass can cost more. Exterior units with sidelights or large glass areas often carry higher prices for both the door package and fitting.
Frame condition is another major variable. Replacing a slab in a sound, square frame is usually cheaper than replacing a prehung unit. Out-of-square openings, water damage, rotted exterior jambs, damaged subfloor, or changed opening dimensions can add $100-$800 or more in carpentry and repair work. If the opening must be resized, obtain a separate line-item estimate.
Finish also matters. A primed door can be economical when the homeowner handles painting, but professional finishing may add $75-$300 per door. Factory finish or specialty colors can raise the purchase price, while matching existing trim may require extra preparation and coats.
Core type and opening condition are two of the strongest price levers. Assumptions: Standard residential door sizes; custom sizes, glass designs, and repairs are priced separately.
Save on Masonite doors by controlling scope and finish choices
Choosing a standard size and a readily stocked design can reduce special-order premiums and avoid delays. For closets or low-traffic rooms, a hollow-core door may meet the need at a lower price; solid-core doors can be reserved for bedrooms, bathrooms, or rooms where sound reduction matters.
Keep a usable frame when it is straight, secure, and undamaged. Replacing only the slab can save the cost of a new prehung assembly and reduce labor, but the replacement must match the frame dimensions, hinge locations, swing, and latch position. If those details do not align, modifying the door may erase the savings.
Compare at least three written estimates using the same door model or equivalent specification. Request separate amounts for the door, installation, hardware, painting, trim, and disposal. This helps identify a low quote that omits finishing or a higher quote that includes useful work other bids exclude.
Handling simple preparation—clearing the work area and moving furniture—can prevent billed setup time. Homeowners should not remove exterior doors or alter structural framing unless qualified; gaps in weatherproofing or an insecure installation can lead to damage and added repair expense.
The best savings usually come from matching the door to the room and avoiding unnecessary frame replacement or upgrades. Assumptions: Existing opening is sound and no code, accessibility, or structural change is required.
How long Masonite door installation takes and what labor covers
A straightforward interior slab replacement often takes 1-3 hours when the frame is sound and the door needs little adjustment. A prehung interior installation commonly takes 3-6 hours, including removal, leveling, fastening, and basic casing work. Painting may require separate visits or drying time even if hands-on labor is short.
Exterior replacements generally take 4-8 hours for a standard opening, with longer schedules for damaged framing, new trim, or difficult access. Two installers may be used for heavy solid-core or exterior units. Labor rates vary, but residential carpentry commonly bills at $50-$100 per hour per worker, with regional minimums and travel charges affecting small jobs.
Ask whether the quote includes door adjustment after installation. A properly fitted door should swing and latch without binding, and exterior units should close against the weatherstripping evenly. Extra fitting can be necessary in older homes where floors, jambs, and walls are not square.
Installation time rises most when the frame must be rebuilt, not simply when the door is heavier. Assumptions: Normal access and a crew experienced with residential door replacement.
Regional Masonite door quotes vary with labor and housing stock
Material prices can be similar across many retailers, but installed prices differ with local wages, contractor availability, and the age of homes. Urban markets and high-cost coastal metros may run roughly 10%-25% above national-average installation prices. Smaller towns can be 5%-15% lower, although limited contractor availability or delivery distance can offset the difference.
Older Northeast and Midwest homes may have nonstandard openings, plaster walls, or worn frames, increasing labor compared with a newer subdivision using common dimensions. In humid or coastal areas, exterior-door quotes may include more attention to sealing and corrosion-resistant hardware. These are job-specific differences, not a fixed regional surcharge.
For a basic interior prehung replacement that might total $450-$750 in a typical market, a high-cost metro quote could be around $500-$940, while a lower-cost market might fall near $380-$710. Exterior work has more variability because weatherproofing and frame repairs can dominate the estimate.
Use regional percentages as a screening tool, then compare local itemized bids. Assumptions: Standard residential scope; regional figures are illustrative and not guaranteed.
Three Masonite door replacement quotes with real project scopes
A basic bedroom slab replacement might include a 30-by-80-inch hollow-core molded door at $120, new hinges and latch hardware at $45, and 2 hours of labor at $75 per hour. Minor fitting and disposal add $60, bringing the estimate to about $375 before painting. This assumes the existing frame remains in place.
A quieter bedroom upgrade could use a 30-by-80-inch solid-core prehung door at $380, hardware at $85, and 4 hours of installation labor at $85 per hour. Casing and removal add $140, for an estimated total of $945. Painting is excluded; adding a professional finish could bring the total to roughly $1,050-$1,200.
A standard exterior replacement may include an insulated Masonite unit with decorative glass at $1,050, hardware and weatherstripping at $180, and 7 hours of labor at $95 per hour. Removal, flashing, and disposal add $250, for an estimated total of $2,145 before any damaged-frame repairs. A rotted jamb could add several hundred dollars.
| Example | Door and materials | Labor and extras | Estimated total |
|---|---|---|---|
| Interior hollow-core slab | $165-$220 | $150-$200 | $315-$420 |
| Solid-core prehung bedroom door | $430-$520 | $480-$650 | $910-$1,170 |
| Insulated exterior door with glass | $1,100-$1,350 | $800-$1,150 | $1,900-$2,500 |
These examples show why installation scope can matter as much as the door selection. Assumptions: Midrange materials and labor; taxes, unusual repairs, and local permit requirements are excluded.
Removal, trim, hardware, and paint can add to the Masonite bill
Old-door removal is often modest when only a slab is being replaced, but taking out a full frame takes more time and may involve wall or trim repairs. Disposal commonly adds $30-$150 per door; bulky debris or local disposal fees can raise the charge. Ask whether the contractor will haul away the old unit.
New casing can add $50-$250 in materials and labor for an interior opening, depending on trim style and how much must be replaced. Exterior brickmold, flashing, sill work, and weatherstripping may add $100-$500 or more when not included in the door package. Water damage should be addressed rather than covered by new trim.
Knobs, levers, privacy locks, deadbolts, and hinges range from about $25-$250 per opening. Existing hardware may be reused if compatible and in good condition, although mismatched finishes or worn latches can make replacement practical. Professional painting typically adds $75-$300 per door depending on preparation and finish.
Some municipalities require permits when a project changes an opening, affects structural framing, or involves certain exterior alterations. A like-for-like interior door replacement usually does not require one, but local rules vary. If a permit or inspection applies, ask the installer to identify the fee and responsibility before work begins.
Confirm removal, trim, finishing, and weatherproofing in writing to avoid surprise add-ons. Assumptions: Typical residential charges; local disposal rates and permit rules vary.
