Masonite interior door prices typically range from $50 to $350 for the door alone, while a professionally installed replacement often totals $250 to $800 per opening. The main cost drivers are whether the door is hollow-core or solid-core, slab or prehung, its size and finish, and how much frame or trim work the opening needs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Masonite door slab | $50 | $160 | $350 | Door only; style and core affect price |
| Prehung interior door unit | $100 | $275 | $600 | Door set in a frame, before installation |
| Professional installation | $150 | $300 | $650 | Per opening; excludes unusual repairs |
| Installed replacement | $250 | $550 | $1,250 | Door, labor, and typical finishing work |
| Custom-size or specialty door | $250 | $500 | $900+ | May require special ordering or extra fitting |

What a Masonite door costs by style and core
A standard Masonite molded-panel hollow-core slab commonly costs $50-$150, with many basic two- or six-panel designs near $80-$120. These lightweight doors suit bedrooms, closets, and other spaces where sound reduction and impact resistance are not major requirements. A prefinished or more detailed molded design can reach $150-$250 before hardware and labor.
Solid-core molded doors generally cost $150-$350 per slab. They weigh more and typically provide better sound control and a sturdier feel than hollow-core versions. Solid-core wood or premium decorative designs can exceed $350, particularly when the size, finish, or panel pattern is not a common stock option. Glass inserts, bifold configurations, and specialty styles can also price above a plain hinged slab.
A slab is only the door panel; it does not include a frame, hinges, or necessarily a handle. A prehung unit includes the door mounted in a frame, which is helpful when the existing jamb is damaged or the opening is being built from scratch. Common prehung Masonite interior units range from about $100-$600, depending on core, style, size, and whether the unit is primed or finished.
For a straightforward standard-size replacement, budgeting $250-$800 installed covers many common hollow-core and solid-core jobs. That range assumes the opening is usable and does not need framing changes, extensive trim replacement, or repainting beyond the immediate work area.
How slabs, frames, labor, and hardware shape the quote
Door quotes often combine several charges that are easy to overlook when comparing a slab price with an installed estimate. Ask whether the written quote includes a new jamb, hinges, latch, casing, disposal, and paint. The table shows typical U.S. ranges for one standard opening, not a guaranteed package price.
| Cost component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Door slab | $50-$350 | Per door | Core, panels, size, and finish |
| Frame or jamb | $40-$150 | Per opening | Wood type, prehung unit, and jamb depth |
| Labor | $150-$400 | Per opening | Slab fit, frame condition, and trim work |
| Hardware and hinges | $20-$120 | Per opening | Basic passage set versus upgraded finish |
| Paint and finishing | $50-$200 | Per door and trim | Priming, number of coats, and site prep |
| Removal and disposal | $25-$100 | Per old door | Hauling distance and local minimum charges |
Labor for a basic slab swap may run $75-$200 when the existing frame is square and the replacement matches the old door. Hanging a prehung unit usually takes more work and can cost $200-$450 in labor because the installer must set, level, and fasten the frame. For example, 2-4 labor hours at $75-$125 per hour produces $150-$500 before materials, travel, or minimum charges.
Finishing is not always included. A primed Masonite door may need painting, and a frame or casing can need touch-up after installation. A quote that includes paint should state whether it covers both door faces, edges, jamb, and trim, as well as whether the homeowner must supply paint.
Compare the complete opening price, not just the listed door price, because frame, finish, and removal can add several hundred dollars. Confirm whether hardware is included and whether the installer is reusing the existing jamb and casing.
Which door size, core, and frame conditions raise the price?
Standard interior doors are often 24, 28, 30, or 32 inches wide and 80 inches tall. Common sizes tend to cost less and are more likely to be in stock. A nonstandard width, a 96-inch-tall door, or a custom cut can add $50-$250 or more for the door and fitting. Cutting a slab substantially may also affect its structure or appearance, so the product’s allowable trim limits matter.
Core type is a substantial price difference. Moving from a hollow-core slab at $50-$150 to a solid-core slab at $150-$350 may add $100-$200 or more per door. Solid core is heavier, so hinge and jamb condition should be checked, especially if an older frame is loose. A heavy door installed on a worn jamb may need reinforcement or replacement rather than a simple hinge adjustment.
Frame condition can shift the job from a low-cost slab replacement to a prehung installation. If the jamb is split, badly out of square, or damaged by moisture, replacement can add $100-$300 in materials and labor beyond a simple slab swap. A rough opening that needs reframing, drywall repair, or relocated hinges may add another $150-$500 depending on access and finish work.
Door configuration also matters. A basic hinged interior door has a simpler installation than a pocket door, bifold closet door, or pair of doors. Changing a hinged door to a pocket door can require opening the wall and moving wiring or plumbing, pushing project totals to $800-$2,000 or more. A glass-panel design can raise material cost and may require careful handling during installation.
Common dimensions and a sound existing jamb are the biggest practical ways to keep a Masonite replacement near the lower end of the range. Measure the slab, jamb, and rough opening before ordering; a width measurement alone does not establish that a prehung unit will fit.
Can an old jamb be reused with a Masonite slab?
Yes, a replacement slab can usually be hung in a serviceable jamb, but it needs to match the opening’s height, width, thickness, hinge locations, and swing. A standard interior slab is often 1 3/8 inches thick, but the existing door should be measured rather than assumed. The new slab may need hinge mortises, a latch bore, or trimming to match the frame.
Slab replacement is generally the lower-cost option when the existing jamb is plumb, secure, and undamaged. Expect roughly $50-$350 for the door plus $75-$200 for straightforward hanging labor. Prehung replacement is more suitable when the frame is damaged or when the opening is new; the unit may cost $100-$600, with installation commonly adding $200-$450.
Matching a slab to an older door can require more fitting than installing a standard prehung unit. Existing hinge locations may not align, and the door may need to be trimmed or drilled. Ask the installer to confirm whether the estimate includes those operations. A low labor quote may assume a stock slab with no modifications.
Reuse a jamb only after checking its alignment and condition, since a damaged frame can undermine the savings from buying a slab alone. If several doors need replacement, measuring and ordering them together can also help avoid mismatched styles and repeated service-call fees.
How long installation takes and what labor usually covers
A simple slab replacement commonly takes 1-3 hours per door when the frame is sound and the replacement dimensions match. A prehung door generally takes 3-6 hours per opening, including removal, setting the frame, shimming, fastening, and fitting trim. Painting, wall repair, or a difficult old frame can extend the work to a full day or longer.
Carpenters and door installers often charge $50-$125 per hour, while some quote a flat $150-$450 labor amount for a standard opening. The hourly rate may not reveal the full cost if the contractor has a trip fee or a minimum job charge. A single door can carry a higher effective per-door rate than several doors installed on the same visit.
Installation scope should specify what happens to the old door and whether the installer adjusts the latch, fills nail holes, and removes packaging. A basic hanging charge may not include casing replacement, paint, or disposal. For multiple doors, request both a per-opening rate and a total project quote; volume can reduce setup time, but each opening still needs fitting.
Plan on 1-6 hours of installation per door, depending mainly on whether the frame stays or is replaced. Scheduling a multi-door project together can reduce repeat travel and setup fees, though labor savings depend on how similar the openings are.
Three realistic Masonite door replacement budgets
A small project with a basic hollow-core slab can stay relatively inexpensive when the old jamb is in good condition. A more complete replacement with a new frame and paint can cost several times the slab price. These examples use typical labor assumptions and exclude major wall repairs.
| Example | Door and scope | Labor assumption | Estimated total |
|---|---|---|---|
| Closet or bedroom slab swap | $90 hollow-core slab, reused jamb, basic hinges | 2 hours at $85-$110 per hour; minor fitting | $275-$400 |
| Solid-core bedroom replacement | $240 slab, new passage hardware, paint | 3 hours at $85-$120 per hour | $550-$800 |
| Prehung door with frame repair | $350 prehung solid-core unit, casing touch-up | 5-7 hours at $85-$125 per hour | $900-$1,400 |
For the first example, the estimate assumes a common 30-by-80-inch door and no frame repair. A wider slab, new casing, or custom hinge work could add $75-$250. The second example includes a solid-core upgrade, which adds material cost and weight; the estimate assumes the existing opening can accept the replacement without reframing.
The prehung example reflects a more involved opening rather than simply a premium door. Frame repairs, casing work, and added finishing can account for much of the higher total. If the opening needs structural changes or extensive drywall repair, the project could exceed $1,400.
Use these totals as comparison points, then check that each contractor priced the same core, size, frame work, hardware, and finish. A quote that omits painting or disposal may look cheaper but leave those expenses outside the stated total.
Why Masonite door installation prices vary by region
Material prices are often similar across national retailers, but local inventory, delivery distance, and contractor availability can change the final quote. In lower-cost rural and Midwestern markets, labor may be around $50-$90 per hour. Large coastal metros and high-cost cities commonly see $85-$150 per hour, with minimum service charges also more frequent.
For a comparable standard replacement, installed prices in high-cost metro areas may run 15%-35% above a lower-cost market. Rural jobs can also cost more if an installer must travel a long distance or make a separate trip for a special-order door. Suburban projects may fall between those examples, although local demand and contractor workload can outweigh broad regional averages.
Delivery can add $25-$100 for a standard door order, and bulky or special-order products may cost more to transport. Retail pickup may avoid delivery charges, but the door must be handled carefully to prevent damage. For a project involving several doors, ask whether delivery and labor are priced once for the project or separately for each opening.
Regional labor and trip charges can move an installed quote more than the price difference between two basic door styles. Compare at least two itemized local estimates and verify that each uses the same installation scope.
Where to trim a Masonite door budget without sacrificing fit
Choose a stock size and a standard molded-panel design if the opening and room do not require a specialty style. A hollow-core door is a lower-cost choice for a closet or low-traffic room, while solid core may be worth the extra price for a bedroom where added weight and sound control matter. Avoid paying for a premium finish if the door will be painted.
Preserve a sound jamb and casing when possible. Reusing them can avoid the cost of a prehung unit and extra trim work, but only if the frame is aligned and the hinges can support the replacement. Have the installer inspect the opening before the door is ordered; correcting a size mistake after delivery can erase any savings.
Get quotes for both slab-only replacement and prehung replacement when frame condition is uncertain. Request separate prices for the door, labor, hardware, paint, disposal, and any repairs. If multiple doors are needed, bundling the work may reduce travel and setup costs. Buying the doors independently can save money during a sale, but confirm the contractor will install customer-supplied materials and ask who handles damage or incorrect sizing.
Do not cut costs by skipping necessary fitting or using unsuitable hinges on a heavy solid-core door. Improper alignment can cause rubbing, poor latching, and repeat labor. Also confirm whether an estimate includes tax, delivery, and disposal, since those smaller charges can add $25-$150 or more to a one-door job.
The safest savings usually come from choosing the right core, reusing a verified sound frame, and comparing itemized quotes before ordering. Keep the measurements, style, finish, and work scope consistent so the lowest bid is genuinely comparable.
