T1-11 plywood siding typically costs $4-$9 per sq. ft. installed, or about $6,000-$13,500 to cover 1,500 sq. ft. of wall area. The final price depends on panel thickness, paint or stain, labor rates, wall preparation, and how much old siding must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| T1-11 plywood panels | $35 per 4-by-8 sheet | $55 per sheet | $85 per sheet | About 32 sq. ft. per sheet before waste |
| Installed siding | $4 per sq. ft. | $6.50 per sq. ft. | $9 per sq. ft. | Basic installation, excluding major repairs |
| 1,500 sq. ft. project | $6,000 | $9,750 | $13,500 | Wall surface area, not home floor area |
| Labor | $2 per sq. ft. | $3.50 per sq. ft. | $5 per sq. ft. | Higher for difficult access or detailed trim |
What T1-11 siding costs on a typical house
For a straightforward replacement, budget $4-$9 per sq. ft. installed, with many standard projects landing near $6-$7 per sq. ft. This estimate assumes ordinary wall access, standard-grade panels, basic fastening and trim, and no extensive framing or water-damage repairs. Prices vary by region and contractor availability.
A 4-by-8-foot panel covers 32 sq. ft. nominally, but a contractor may order extra for cuts, corners, gables, and damaged pieces. A practical order allowance is about 5%-10% over the measured siding area. At $35-$85 per sheet, the panel material alone comes to roughly $1.10-$2.65 per sq. ft. before waste, fasteners, trim, coatings, or delivery.
For a smaller 800-sq.-ft. siding area, the installed total is approximately $3,200-$7,200. A 2,000-sq.-ft. exterior could run $8,000-$18,000 at the same broad rate. These figures describe siding surface, which can differ substantially from the home’s interior floor area because of windows, doors, roof shape, and the number of stories.
Assumptions: U.S. contractor pricing, standard wood-grain panels, normal access, and limited wall repair.
What panel, trim, and labor charges add to the quote
Panels are only one part of the bill; labor, finishing, and removal can bring the installed total to several times the sheet price. The ranges below are typical planning figures, not fixed national rates. Contractors may quote by square foot or combine several tasks into a single project price.
| Quote item | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Panel materials | $1.10 per sq. ft. | $1.75 per sq. ft. | $2.65 per sq. ft. | Panel cost before waste |
| Installation labor | $2 per sq. ft. | $3.50 per sq. ft. | $5 per sq. ft. | Cutting, fitting, fastening |
| Trim and flashing | $0.50 per sq. ft. | $1.25 per sq. ft. | $2.50 per sq. ft. | Corner boards, openings, transitions |
| Paint or stain | $0.75 per sq. ft. | $1.50 per sq. ft. | $3 per sq. ft. | Preparation and coating application |
| Removal and disposal | $1 per sq. ft. | $2 per sq. ft. | $4 per sq. ft. | Existing siding; more for difficult layers |
Labor often represents a large share of the price. A crew may charge a blended rate equivalent to $50-$100 per worker-hour, depending on local wages, business overhead, and job complexity. For estimating purposes, can help check whether a quote’s labor allowance is plausible; the contractor’s actual labor method may instead use a per-square-foot bid.
Trim costs depend on how many windows, doors, outside corners, and roofline transitions need finishing. A simple rectangular wall needs fewer cuts than a facade with numerous openings. Ask whether the bid includes corner trim, flashing, caulk, starter details, fasteners, coatings, and disposal so separate charges do not emerge after work begins.
How thickness, grade, and wall access change panel prices
Panel thickness and installation conditions can shift a T1-11 quote by several dollars per square foot. Common panels are 3/8, 5/8, and 3/4 inch thick. Thicker sheets generally cost more and weigh more, but the correct choice depends on framing, local requirements, and the manufacturer’s installation instructions. A change from a basic 3/8-inch panel to a thicker panel can add roughly $10-$30 per sheet, depending on product and market.
Groove spacing and panel appearance also affect selection. T1-11 is commonly sold with 4-inch or 8-inch grooves, while surface texture, wood species, and finish quality vary. A higher-grade plywood face may cost more than a basic panel, and panels intended for exterior exposure need suitable ratings and protective finishing. Buyers should compare the panel stamp and product specifications, not just the name T1-11.
Access is another major price driver. A one-story wall with clear ground access may fit the lower labor range. Two-story elevations, steep slopes, narrow side yards, or extensive ladder and scaffold work can add 10%-25% to labor. More than 10% of the wall area in gables, dormers, or numerous openings can also increase cutting time and waste.
Underlying damage can raise the total beyond the siding allowance. Replacing isolated sheathing may add about $2-$5 per sq. ft. of affected area, while repairing framing or water-damaged wall sections requires a separate inspection and quote. If damage is hidden, the contract should explain how change orders will be priced once the old siding is removed.
Ways to lower the T1-11 replacement bill
The most reliable savings come from controlling the work scope and choosing a panel that meets the building’s needs without paying for unnecessary upgrades. Measure the wall area carefully and ask for the quote to list square footage, panel type, trim, coating, removal, and repairs separately. Itemized bids make it easier to compare contractors and identify scope differences.
Keep sound existing trim where practical, but do not reuse components that are rotten, poorly flashed, or incompatible with the new siding. If only a few panels are damaged and the remaining siding is sound, compare a targeted repair with full replacement. Matching old groove patterns and faded finishes can be difficult, so repair is most economical when the damage is limited and appearance is not a major concern.
Standard panel sizes and uncomplicated layouts reduce cut waste. Bundling siding work with other exterior repairs may reduce repeat mobilization charges, although a combined quote should still break out each trade. Homeowners can clear shrubs and movable obstacles before installation, but should leave siding removal, wall repairs, and work at height to qualified crews when safety or building-envelope details are involved.
Get at least three written quotes based on the same panel thickness, finish, removal scope, and trim details. A low bid may exclude paint, disposal, flashing, or sheathing repairs. Ask whether the contractor carries insurance, what workmanship coverage applies, and how additional damaged areas will be documented and approved.
Regional labor rates and delivery can move the total
Local labor and transport commonly explain why identical panel projects receive different quotes across the country. As a broad comparison, labor in high-cost coastal metro areas may run 15%-30% above a national midrange estimate. Smaller towns and some rural markets may come in 5%-15% below it, though fewer available contractors can erase that difference.
Panel availability, freight distance, and local demand also matter. A supplier close to the job may deliver standard sheets at modest cost, while a remote location or a small order can incur a delivery charge of roughly $75-$250. Special-order panels, limited stock, or a tight construction schedule can raise material expense. These are directional comparisons; local quotes are more useful than applying a nationwide percentage mechanically.
Season and weather affect scheduling more than the panel’s listed price. In regions with a short dry season, contractors may have limited availability during peak exterior-work months. A flexible start date can make it easier to schedule the project, but the buyer should not choose a lower-priced installation window if rain, temperature, or product instructions make proper finishing impractical.
Three T1-11 quotes for different home sizes
These examples show how area, finish, and removal scope translate into realistic project totals. Each assumes ordinary framing and no major hidden water damage. Actual estimates should use the measured exterior wall area and local labor rates.
| Project | Scope and labor | Unit estimate | Estimated total |
|---|---|---|---|
| Small detached garage | 600 sq. ft.; 2-person crew for 2 days; new panels and basic trim | $4.50-$7 per sq. ft. | $2,700-$4,200 |
| One-story home replacement | 1,500 sq. ft.; 3-person crew for 4-6 days; removal and repainting | $6-$9 per sq. ft. | $9,000-$13,500 |
| Two-story exterior | 2,000 sq. ft.; 3-person crew for 6-9 days; scaffold access and detailed trim | $7-$11 per sq. ft. | $14,000-$22,000 |
The garage example assumes no old siding removal and straightforward access. The one-story replacement includes ordinary disposal and a new exterior coating, but not widespread sheathing work. The two-story range reflects added setup, trim labor, and access challenges; extensive repairs could take the final bid above the estimate.
Crew schedules are approximate because weather, panel cutting, repairs, and finish-drying time can change the work sequence. Ask the contractor to separate installation days from painting or staining days, and confirm whether the labor total includes setup, cleanup, and hauling debris.
Repairing a few panels versus replacing the siding
Replacing isolated damaged panels can cost less than a full re-side, but widespread moisture problems or repeated failures may make replacement more economical over time. A small repair may cost $300-$1,200, including a service minimum, one or two panels, trim work, and touch-up coating. Larger repairs covering 100-200 sq. ft. may reach $800-$2,000, especially when matching and blending the finish takes extra labor.
Full replacement has a higher initial price but allows the contractor to inspect more of the wall, update flashing, and finish the exterior consistently. If damage is confined to one wall or a few locations, a partial replacement may be a middle option. Its per-square-foot rate can be higher than a whole-house job because mobilization, setup, and trim work are spread over less area.
Compare the condition of the siding and the wall behind it before deciding. Soft panels, swelling at lower edges, open joints, or recurring leaks can signal a broader moisture issue. Replacing the visible panel without correcting drainage, flashing, or water entry may lead to another repair bill. A contractor should identify the suspected source and list any wall repairs separately from siding installation.
When matching existing siding, bring a sample or provide panel dimensions, thickness, groove spacing, and product markings. Older panels may no longer be available in the same profile. A close match may still require replacing a full wall plane or coating a larger area to avoid obvious color differences.
Removal, paint, and permits that may appear separately
Confirm removal, finish work, and local approval costs before comparing final bids. Removing existing siding typically adds $1-$4 per sq. ft., depending on the number of layers, fastener type, access, and disposal rules. Hauling may be included or billed separately; a dumpster or special disposal requirement can add roughly $300-$800 to a project.
New panels usually need a compatible exterior coating or finish, and the required preparation matters. Basic painting may fall around $0.75-$2 per sq. ft. when included with a larger siding job, while extensive scraping, priming, or detailed color work can reach $3 per sq. ft. or more. Stain and paint are not interchangeable choices for every panel; follow the panel manufacturer’s finish requirements and local climate guidance.
Permit rules depend on the city or county and on whether the project is a repair, re-siding, or broader exterior alteration. A simple siding replacement may require no permit in some jurisdictions, while others require an application or inspection. Where required, permit fees may range from about $50-$500, with higher charges possible for larger projects or additional code work.
Ask whether the estimate includes required flashing, weather-resistive barrier, and any code-related upgrades discovered during inspection. A quote should distinguish these items from optional improvements. The local building department can confirm permit requirements, while the contractor can explain which details are necessary for a compliant installation on the specific home.
