Estimating doors labor starts with a clean takeoff, a real crew, and an honest production rate. Doors look simple on a schedule, but the labor hides in hardware, framing modifications, casing, and field fit. The number you commit to should come from your own past jobs, sized to the conditions in front of you, not a single line item rate pulled off a price book.
What You Are Counting
Before you can estimate labor you have to count the work in the units your crew thinks in. For a door scope that means doors (EA), frames (EA), hardware sets (EA), trim or casing (LF), and any prep work like re framing a rough opening or shimming an out of square wall. Each of these is a separate labor driver because the crew and the hours per unit differ.
A clean takeoff separates the work into buckets: hollow metal doors versus wood doors versus storefront aluminum, because each pulls a different crew. Count every hardware set as one unit, not as individual hinges and locks, because your installer will hang, set hardware, and adjust as a single operation per door. List casing or trim by the linear foot around each opening, typically 6 to 9 LF per single door and 12 to 16 LF per double. If the schedule calls for fire rated doors or acoustic doors, flag them now because the installation and testing time is meaningfully higher.
Crew and Production Rate
Pick your crew before you pick your rate. A common residential and light commercial door crew is two carpenters, one lead and one helper, sometimes a third hand for moving heavy units on a large job. For commercial hollow metal and hardware you may use a carpenter plus a dedicated hardware installer. The crew composition drives both the wage you average and the speed at which doors go in.
The bare wage range for door and carpentry work runs roughly $22 to $40 per hour depending on region, license level, and union or open shop. Add labor burden on top of that: payroll taxes, workers comp, insurance, and benefits commonly add 30 to 45 percent to the bare wage. A $30 bare wage becomes $39 to $43 fully burdened. That burdened number is what you multiply against labor hours to get direct labor cost.
Production is expressed as man hours per door, frame, and hardware set. A typical range for a straightforward interior wood door with prehung frame and a basic lockset is in the 1.5 to 2.5 man hour zone for hang, hardware, and adjust. Hollow metal with commercial hardware runs higher, often 2.5 to 4 man hours per opening once you include frame install, door hang, full hardware, and adjustment. Casing runs roughly 0.05 to 0.1 man hours per LF depending on profile. RSMeans is a common reference for production rates, but the most reliable number is your own history from similar work.
Step by Step Labor Estimate
Run the math in the same order every time so nothing slips:
- Takeoff quantities: doors, frames, hardware sets, casing LF.
- Assign a crew and a fully burdened wage rate for that crew.
- Apply a production rate (man hours per unit) to each quantity.
- Multiply to get total man hours, then multiply by the wage for labor cost.
- Add productivity factors for complexity, height, congestion, or learning curve.
- Add non install hours: mobilization, layout, punch list, cleanup.
For a representative scope of 20 doors, 20 frames, and 20 hardware sets, a reasonable build is 20 openings at roughly 2.5 man hours per opening for hang, frame, hardware, and adjust, giving 50 man hours. At a $35 burdened wage that is $1,750 in direct labor. Add casing at 160 LF and you layer in another 12 to 16 man hours. That is the shape of the estimate, not a single number pulled from a table.
Factors That Move the Number
Production rates are not constants. They shift with the conditions you actually find in the field, and a good estimate bakes those shifts in rather than hoping the average holds.
- Access and height: doors on upper floors or in tight corridors eat time on material handling.
- Out of square openings: shimming and re framing add man hours that are not on the plan.
- Hardware complexity: mortise locksets, closers, and electrified hardware take longer than cylindrical locks.
- Fire rated and labeled openings: testing, paperwork, and adjustment add hours per opening.
- Crew experience: a lead who has hung a thousand doors runs faster than a first year carpenter.
- Weather and site temperature: cold jobsites slow hands and adhesives, especially on exterior doors.
Common Mistakes
The estimates that lose money tend to share the same fingerprints. Watch for them before you send the number.
- Using one flat productivity number for every door type and complexity.
- Forgetting mobilization, layout, punch list, and cleanup hours, which can be 10 to 15 percent of install time.
- Applying the bare wage instead of the burdened wage, underpricing labor by a third.
- Ignoring access: upper floor work and tight stairwells are slower than ground floor open bays.
- Leaving hardware out of the door count and then doubling back to add it as an afterthought.
- Not pricing field modifications when the openings are out of tolerance.
Putting It Together
The right door labor estimate is a range, not a single point. Take the low end of your production range for simple interior doors in good conditions with an experienced crew, and the high end for rated, hardware heavy, or hard to reach openings. Add the non install hours separately so they do not get lost in the unit rate. Then check the total against two or three past jobs of similar size. If your number is well below your own history, trust the history. Keep a simple log of man hours per opening by type and you will not need a price book next time.
