T1-11 siding typically costs $4-$9 per sq. ft. installed, or about $6,000-$13,500 for 1,500 sq. ft. of siding. The final price depends on plywood versus OSB panels, wall preparation, labor rates, trim and paint requirements, and whether old siding must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed T1-11 siding | $4/sq. ft. | $6.50/sq. ft. | $9/sq. ft. | Panels and standard installation |
| 1,500 sq. ft. project | $6,000 | $9,750 | $13,500 | Before major repairs or complex trim |
| Panels only | $1.50/sq. ft. | $2.75/sq. ft. | $4.50/sq. ft. | Material grade and region affect price |
What T1-11 siding costs on a typical home
For a straightforward replacement covering 1,500 sq. ft. of exterior wall, a practical budget is $6,000-$13,500 installed, with roughly $9,750 as a planning midpoint. The estimate assumes standard 4-by-8-foot panels, ordinary wall access, typical trim, and no extensive rot repair. Actual siding area is not the same as a home’s floor area; windows, doors, gables, and wall height change the measurement.
Panel-only pricing often falls between $1.50 and $4.50 per sq. ft. Installed pricing adds labor, fasteners, cutting, trim work, and sometimes caulking or coating. Assumptions: U.S. mid-market labor, standard panel finish, normal access, and sound sheathing. For budgeting, use the measured exterior wall area and confirm whether the quote includes finishing and removal.
How panel, labor, and removal charges add up
Contractor estimates vary in what they include. The following breakdown shows common ranges per square foot of siding area for a basic project; components may be bundled rather than listed separately.
| Materials | Labor | Equipment | Delivery/Disposal | Typical total |
|---|---|---|---|---|
| $1.50-$4.50/sq. ft. | $2-$4/sq. ft. | $0.25-$0.75/sq. ft. | $0.25-$1.50/sq. ft. | $4-$9/sq. ft. |
| Panels, nails, flashing, trim | Fit, cut, fasten, and finish | Ladders or lift as needed | Hauling and disposal if included | Basic accessible installation |
Material costs rise when a project needs premium plywood, prefinished panels, substantial trim, or replacement flashing. Removal and disposal can add roughly $1-$3 per sq. ft., depending on the existing siding, local disposal fees, and whether multiple layers are present. Sheathing repairs are usually extra and may be priced by the damaged area.
Labor is often quoted by the project or square foot rather than as a separate hourly charge. When a contractor does provide an hourly rate, $50-$100 per worker-hour is a reasonable broad planning range, with local rates varying. Ask whether the bid includes tear-off, disposal, trim, flashing, caulk, and cleanup before comparing totals.
Panel thickness, wall height, and damage change the quote
T1-11 panels commonly come in 4-by-8-foot sheets, but thickness, wood type, and groove spacing affect both price and installation. Thinner or lower-cost OSB panels may cost less upfront than plywood; plywood often carries a higher material price. Panel labels and manufacturer instructions should be checked for the required thickness, exposure rating, and installation details.
Wall height can add labor because two-story work may require scaffolding or a lift, while narrow gables and many corners increase cutting time. A 10% increase in measured siding area generally raises panel and installation costs by a similar amount. Rot, soft sheathing, or failed flashing can add several hundred dollars or more, depending on how much wall must be opened and repaired.
Finish also changes the budget. Unfinished panels may need primer and paint or stain after installation; a coating can add about $1-$3 per sq. ft. when handled by a contractor. Confirm whether the price is for bare panels or a finished, weather-protected exterior.
Ways to lower a T1-11 replacement estimate
Accurate measurement is one of the simplest ways to avoid overbuying. Have the quote show net wall area, panel count, waste allowance, and trim quantities; an allowance around 5%-10% for cuts is common, but complex walls may need more. Reuse sound trim only when it can be removed without damage and still provides a proper weather barrier.
Compare at least three written estimates with the same scope, panel type, thickness, and finish. If existing panels are sound and damage is limited to a small area, ask whether a localized repair is feasible instead of full replacement. However, covering deteriorated siding without addressing trapped moisture can lead to more expensive repairs later.
Choosing standard panels and scheduling outside a contractor’s busiest period may help control the quote, but material suitability and correct installation matter more than the lowest panel price. Keep scope consistent when comparing bids so a lower total does not simply reflect omitted removal or finishing.
Regional labor rates can shift installed T1-11 prices
In lower-cost rural markets, straightforward installation may land near the bottom of the national range. Major metro areas and regions with high contractor demand can run roughly 10%-25% above a mid-market estimate; remote locations may also pay more because of delivery distance and limited crew availability. These differences are not guaranteed and can be offset by local material supply or seasonal workload.
Climate and local building requirements can affect the needed weatherproofing details, flashing, and finish system. Coastal exposure, heavy rain, and freeze-thaw conditions may call for more careful detailing or higher-grade coatings. Use local written bids rather than applying a national per-square-foot figure without adjusting for access and labor.
Removal, paint, and trim are common added charges
Replacing old siding can involve more than panel installation. Tear-off may cost about $1-$3 per sq. ft., while extra hauling, dump fees, or difficult access can raise the charge. New corner boards, window trim, fascia tie-ins, or flashing are often priced separately; modest trim work may add a few hundred dollars, while extensive replacement can add substantially more.
Painting or staining unfinished T1-11 may add $1-$3 per sq. ft. for contractor-applied preparation and coating, with the exact price depending on surface condition, number of coats, and access. If a quote excludes painting, buyers should budget for the work rather than treating the panel-only price as a completed exterior. Separate base installation from optional repairs and finish work to see what is driving the total.
What a 1,000-square-foot siding quote might include
A 1,000 sq. ft. job using standard panels on a one-story wall with easy access might total about $4,000-$7,000 before unusual repairs. That range assumes roughly $1.50-$3.50 per sq. ft. for panels and related materials, plus labor and basic installation supplies. Removal, painting, or extensive trim replacement can push the price higher.
A two-story job with OSB panels, old siding removal, and moderate trim work could reach $7,000-$10,000 for the same wall area because of additional labor and access needs. A smaller repair replacing a few panels may cost more per square foot than a full project because contractors may charge a minimum service fee or mobilization charge. Request both the total price and the measured area so the quote can be compared on a consistent basis.
