Garage door header replacement typically costs $1,000-$5,000, with many standard residential projects near $2,500. The garage door header is the structural beam above the opening; price depends on opening width, material, access, local labor, and whether the surrounding framing or finishes need repair.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Header replacement | $1,000 | $2,500 | $5,000+ | Typical residential structural work |
| Installed header material | $15 | $35 | $75+ per linear ft | Varies by lumber, engineered wood, or steel |
| Engineer or permit | $150 | $500 | $1,200+ | Depends on local rules and design needs |
| Temporary door support | $150 | $400 | $800 | May be needed while the opening is braced |
What a Residential Garage Header Usually Costs
For a standard one-car opening about 8-10 feet wide, a straightforward replacement often falls around $1,000-$2,500. A two-car opening around 16 feet wide commonly costs $2,000-$4,500, while wide, damaged, or unusually configured openings can exceed $5,000. These estimates cover structural header work, not a new garage door or opener.
Material choices include dimensional lumber, engineered wood such as LVL, and steel. The right size and type depend on the span, roof load, wall construction, and local code; a contractor should not select a beam based on price alone. Assumptions: typical U.S. labor rates, residential wood-frame garage, standard access, and no major foundation repairs.
A typical budget is $1,000-$5,000, but wide openings and added structural work can push the total higher.
How Beam, Labor, and Permit Charges Add Up
Quotes may bundle several tasks rather than price each independently. The table gives common allowances; actual line items vary with opening size, finishes, and whether the contractor manages engineering or permits.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Header material | $150 | $450 | $1,200 | Beam, fasteners, and basic framing materials |
| Carpentry labor | $600 | $1,400 | $3,000 | Bracing, removal, installation, and reframing |
| Equipment and support | $150 | $400 | $900 | Temporary shoring, lifts, or added crew time |
| Engineering and permits | $0 | $500 | $1,500 | Plans, calculations, permit, or inspection fees |
| Finish repair and disposal | $100 | $450 | $1,200 | Trim, drywall, siding, and debris removal |
Labor commonly accounts for the largest share because the door opening must be safely supported before the old header is removed. For a crew, a rough labor estimate can be checked with ; combined carpenter rates may run about $75-$150 per hour, depending on region and crew size.
Ask whether the quote includes temporary support, finish restoration, disposal, and permit handling.
Opening Width and Roof Load Change the Beam Price
Span is a major cost driver: moving from a 9-foot opening to a 16-foot double-door opening can require a larger or engineered beam and more intensive shoring. Openings wider than about 18 feet, unusually heavy roof loads, or a room above the garage may call for engineering and specialized installation, adding several hundred to more than $1,500.
Water damage, insect damage, or rot extending into the jack studs and surrounding wall framing can add roughly $300-$2,000 or more. Brick veneer, stone, tight interior access, and attached rooms can also increase labor. Steel beams may be appropriate for some long spans but can require equipment to position and additional connection work.
Confirm the measured opening, beam specification, and any supporting-wall repairs before comparing totals.
How Long Does Header Replacement Take?
A simple replacement may take one workday, while larger openings or projects involving engineering, permits, and finish repairs can take two to five working days. The actual structural work may be completed in 6-12 hours, but scheduling an inspection or waiting for a custom beam can extend the calendar time.
Some jobs require removing or disconnecting the garage door and opener before temporary bracing is installed. Ask whether that work is included, and whether the garage must remain inaccessible overnight. If the door cannot be safely reinstalled promptly, temporary weather protection or separate door-service charges may apply.
Labor duration and door handling should be stated separately from permit or material lead time.
Three Garage Header Quotes With Different Scopes
A quote is easier to evaluate when it identifies the opening size, beam, labor, and finish work. These examples are illustrative U.S. estimates rather than guaranteed bids.
| Scenario | Specifications | Labor | Estimated total |
|---|---|---|---|
| Small single-car garage | 9-ft opening, wood beam, minor trim work | 8-10 hours | $1,200-$2,200 |
| Standard two-car garage | 16-ft opening, engineered wood, permit allowance | 12-18 hours | $2,400-$4,200 |
| Wide opening with damage | 18-20-ft opening, engineered beam, framing and finish repair | 18-28 hours | $4,000-$7,000+ |
Assumptions: ordinary access and locally typical labor; extensive masonry work, custom steel, or major roof repairs may exceed these ranges.
Compare the same scope and beam specification, not just the bottom-line number.
Repairing the Existing Header Versus Replacing It
If damage is limited to trim or a small area of nonstructural framing, repairs may cost about $300-$1,000. A structural engineer or qualified contractor should assess suspected sagging, cracking, or rot; adding a board over a failing beam may not restore its capacity. Replacement is more likely when the beam is undersized, deteriorated across its span, or no longer supports the opening properly.
Ask a contractor to explain why repair is or is not feasible and whether the quote includes the affected supports. A second opinion can be useful when one bid proposes a full replacement and another proposes a small patch.
Choose repair only when the structural condition and proposed fix are clearly documented.
Which Work Can Reduce the Replacement Bill?
Get two or three itemized quotes that state beam dimensions and material, support method, labor, permit fees, and excluded finish work. If the garage door is being replaced too, coordinate the projects so door removal or disposal is not charged twice; do not assume the door installer can perform structural work.
Keeping sound trim and siding in place, clearing stored items from the work area, and arranging the work during normal scheduling can reduce added labor. Avoid choosing a smaller beam or skipping required engineering to lower the bid. Also confirm whether taxes, debris hauling, inspection visits, and any repair to water-damaged framing are included.
The safest savings come from clear scope, comparable bids, and avoiding duplicate removal or finish charges.
Why Local Labor and Permits Shift Garage Header Prices
Labor and contractor availability can put a quote in a high-cost metro area roughly 15%-30% above a comparable project in a lower-cost rural market. Remote locations may also carry travel or delivery fees, while dense urban areas can add costs for access, parking, or material handling. These are broad differences, not fixed regional rates.
Permit requirements vary by city and by whether the header is structural or changes the opening size. Permit and inspection charges may be modest, but required stamped calculations can add $300-$1,200 or more. Check local rules before work begins, and ask whether the contractor’s price includes application fees and inspection corrections.
Local code, engineer requirements, and access conditions can change the final estimate as much as the beam material.
