Garage door capping typically costs $300-$900 per opening, with many homeowners paying about $550 to cover exterior wood trim with formed aluminum coil. The final price depends on opening size, trim condition, access, local labor rates, and whether old material or damaged wood must be removed or repaired.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Single-door capping | $300 | $450 | $700 | Usually 24-30 linear ft of trim |
| Double-door capping | $450 | $700 | $1,100 | Usually 28-38 linear ft of trim |
| Installed price per linear ft | $8 | $14 | $22 | Trim complexity and labor affect the rate |
| Wood repair before capping | $75 | $250 | $600+ | Depends on rot, extent, and access |
What garage door capping costs for single and double openings
For a standard single-car garage door, expect roughly $300-$700 to cap the exterior casing with aluminum coil. A typical quote is around $450-$500 when the existing trim is sound, the opening is easy to reach, and the contractor can complete the work without extensive repair. A larger double opening commonly costs $450-$1,100, averaging about $700-$800.
These estimates generally cover measuring, bending coil to fit the trim, fastening it, and sealing exposed joints. They assume ordinary white or commonly stocked aluminum, standard residential access, and no major framing or painting work. Custom colors, elaborate profiles, unusually wide trim, or several openings on the same home can change the total.
A useful starting budget is $10-$18 per linear foot installed, or about $450-$800 for a typical opening. Some contractors price per opening rather than by footage, so the quote should identify the trim length and what the base charge includes.
Assumptions: U.S. residential project, standard formed aluminum coil, sound wood trim, normal ladder access, and no major code or structural work.
How aluminum coil, labor, and removal appear in a capping quote
Most capping estimates combine coil stock and small supplies with setup, cutting, bending, fitting, and sealing labor. The aluminum itself is only part of the total: the work requires accurate bends around corners and a close fit to the existing casing. Quotes may also include removal of loose old wrapping, haul-away, or minor preparation.
| Quote component | Typical price | What changes the charge | Common billing basis |
|---|---|---|---|
| Aluminum coil and fasteners | $2-$6 per linear ft | Gauge, color, and stock availability | Material allowance or included |
| Forming and installation labor | $6-$15 per linear ft | Corner details, height, and crew time | Per foot or fixed project fee |
| Sealant and finishing supplies | $15-$60 total | Number of joints and color match | Usually included |
| Old wrap removal and disposal | $50-$200 | Fasteners, layers, and disposal needs | Separate line item or hourly |
| Minor wood preparation | $75-$300 | Loose boards, caulk, and small patches | Time and materials |
Labor rates for exterior trim work often fall around $50-$100 per hour, but many contractors use a minimum charge for a small job. A two-person crew may finish a straightforward opening in 3-6 hours, including setup and cleanup. This labor estimate is not a guarantee; complex bends, difficult access, or multiple openings can extend the workday.
Ask whether the quote includes old-wrap removal, sealant, cleanup, and any minimum service charge. Comparing those inclusions is more useful than comparing the total alone.
How opening width, trim condition, and coil grade change the price
Opening size is a major driver because more perimeter generally requires more stock and forming time. A single door around 8-9 feet wide may have roughly 24-30 linear feet of casing to cover. A double door around 16 feet wide often has 30-38 linear feet, depending on the top trim, side extensions, and whether the job includes a center post or adjoining trim.
Trim condition matters before the coil goes on. Sound, dry wood can usually be wrapped as-is after cleaning and minor preparation. Soft or rotted wood should not simply be concealed: replacing a few short sections may add $75-$250, while extensive casing repairs can add $300-$600 or more. Hidden water damage discovered after removal can require a revised estimate.
Coil thickness, finish, and color also affect material pricing. Standard white coil is often the least expensive option; a less common color or a finish matched to the home may add about $50-$200 per opening, depending on availability and material quantity. Extra-wide casing or decorative profiles can require more stock and custom bends.
Measure the casing perimeter and inspect the wood before accepting a fixed price. A difference of 6-10 linear feet, or repair work across several feet of trim, can shift the quote substantially. Contractors should specify whether their footage includes the top, both sides, and any separate return trim.
Which prep and material choices can trim a capping estimate
Homeowners can control cost by keeping the project scope clear. If only the exposed garage-door casing needs protection, ask for a quote limited to that trim rather than bundling unrelated siding or decorative work. Have the contractor list extra charges for wood repair separately so necessary repairs are not confused with optional upgrades.
Standard stock color and a simple folded profile usually cost less than custom color or elaborate detailing. Where the existing trim is in good condition, preserving it and wrapping it is generally less expensive than removing and replacing the casing. However, wrapping damaged wood to avoid a repair can trap moisture and lead to a larger expense later.
Clearing stored items, plants, or vehicles away from the work area can reduce setup delays, though it usually does not eliminate a contractor’s minimum charge. For multiple openings, request a combined estimate: repeated setup and material handling may lower the per-opening rate, but each opening should still be itemized.
Choose standard coil, limit the scope to sound trim, and compare itemized quotes. Avoid choosing the lowest bid without checking material thickness, finish, corner workmanship, cleanup, and whether the contractor will address damaged wood.
Why garage door capping prices vary by U.S. region
Regional labor and travel costs can move the total by roughly 10%-25% compared with typical mid-range pricing. Large metropolitan areas and high-cost coastal markets may price a standard single opening at $500-$850 and a double opening at $700-$1,300. Smaller cities and rural markets may see simpler single-door work closer to $300-$550 and double-door work around $450-$850.
Those differences are not fixed geographic rules. Local contractor availability, minimum charges, material sourcing, and the distance to the job all matter. A rural contractor may quote a travel or service fee of $50-$150, while a busy urban contractor may have higher labor rates but shorter travel time between jobs.
Season and weather can affect scheduling more than the price of coil. Exterior work may be delayed by rain, freezing temperatures, or wind, and urgent work during a short weather window can be harder to schedule. Most ordinary capping jobs do not require a special seasonal premium, but a tight deadline or a one-off visit can increase the minimum charge.
Use local quotes as the benchmark, then compare the same opening size and scope. A national per-foot figure is only a planning aid; the contractor’s minimum, region, and access conditions can outweigh small differences in material cost.
How long a trim crew needs and what a minimum charge covers
A straightforward single opening often takes one experienced installer or a small crew about 3-5 hours on site. A double opening may require 4-7 hours, especially when the top casing is wide or corners need careful custom forming. The job may take longer if old capping must be removed, wood needs repair, or the work area is difficult to access.
Because setup, measuring, bending, and cleanup take time even on a small opening, contractors may charge a minimum of $250-$400. Hourly labor can help explain a quote, but it does not always predict the bill: fixed-price estimates may include travel, equipment, insurance, and time spent preparing the coil.
Ask whether the crew will complete all sides in one visit and whether additional labor is billed by the hour or as a change order. A clearly stated time-and-materials rate can be useful when the wood condition is uncertain. For a fixed bid, request a written description of what happens if hidden rot is uncovered.
For a typical opening, a half-day crew visit is common, but minimum charges make very small jobs costlier per foot. If several trim openings need capping, scheduling them together can spread setup time across more work.
What three realistic garage door capping quotes include
A basic single-door quote might cover 26 linear feet of standard white coil at an installed rate near $12 per foot, plus minor supplies. The resulting price is about $310-$400 after a small-job minimum or setup charge. This assumes sound casing, easy access, no old material to remove, and a simple profile.
A typical double-door project might cover 34 linear feet at about $14 per foot, with a modest allowance for sealant and finishing. A reasonable total is $500-$650 when the casing is in good shape and the contractor does not need to replace wood. This type of estimate often reflects roughly 4-6 hours of crew time.
A more involved double opening could run $850-$1,200 if it needs removal of old wrap, replacement of several feet of damaged casing, custom-color coil, and extra labor for awkward access. For example, the base capping could be $650-$800, with $150-$300 for wood repair and $50-$100 for removal or disposal.
Compare estimates by matching linear footage, material finish, repairs, removal, and labor—not just the quoted total. For all three examples, taxes may be extra where applicable, and substantial hidden damage could require a written change order.
When repair or replacement makes more sense than wrapping
Capping covers and protects exposed exterior trim; it does not repair a failing garage door, correct water entry, or replace structural casing. If the wood is solid but faded or exposed to weather, wrapping can avoid repeated painting and may be a practical option. If the casing is badly split, soft, or pulling away from the wall, repair or replacement should be priced before the new aluminum is installed.
Replacing a limited section of casing may add $150-$400, including basic materials and labor, while broader trim replacement can cost $400-$1,000 or more depending on length and finish work. Full exterior trim painting may be less expensive initially in some areas, but it does not provide the same metal covering and will need periodic maintenance.
Garage door replacement is a separate, much larger project and is not a direct substitute for capping sound trim. If the door itself has operating, safety, or panel damage, request a separate door inspection rather than assuming trim work will address it. Capping should not interfere with weather seals, tracks, or door movement.
Wrap stable, dry casing; repair deteriorated wood before covering it. This distinction helps prevent paying for attractive new capping that must later be removed to reach hidden damage.
