What Is T1-11 Siding?
T1-11 siding is an engineered wood panel commonly used for exterior cladding. It is identified by its vertical grooves every 4 or 8 inches and usually comes in 4×8 foot sheets. There are two main types: plywood-based and oriented strand board (OSB). T1-11 is especially popular on sheds, barns, and outbuildings due to its rustic, natural wood appearance and affordability.
T1-11 Plywood Vs. OSB
- Plywood T1-11: Made from layers of wood veneer, more durable, water-resistant, and often costs more.
- OSB T1-11: Constructed from compressed wood strands and adhesives, less expensive, can be less durable in damp climates.

| Labor | Your time | $2.50 – $4.50 / sq. ft. |
| Total Cost per sq. ft. | $2.10 – $4.50 | $4.00 – $8.00 |
DIY is best suited for small structures, outbuildings, or experienced woodworkers. Larger homes, or those with complex designs or exposure issues, generally benefit from professional installation for better weatherproofing and longevity.
Regional Price Variations Across The United States
T1-11 siding costs fluctuate depending on region. Regions with abundant lumber production, such as the Pacific Northwest, may see lower material costs. East Coast and Southern states can be higher due to transportation costs or humidity effects requiring better sealing.
- West Coast: Material and labor costs are average or slightly below average.
- Midwest: Typically competitively priced with good contractor availability.
- Northeast & South: Often higher due to variable weather and shipping fees.
Always obtain several quotes from local suppliers and contractors to understand current prices in your area.
Cost Of Painting Or Staining T1-11 Siding
The initial finish significantly affects total expense. While some panels are available primed, most require a good quality paint or stain for weather resistance and visual appeal. Expect these costs:
- Exterior Acrylic Paint: $35 – $60 per gallon for premium products
- Stain (Oil or Water-Based): $35 – $55 per gallon
- Labor (pro): $1.00 – $1.75 per sq. ft. for complete paint application
- DIY Materials: Brushes, rollers, drop cloths, ladders/scaffold: $50 – $250 total
High-quality, thick coatings last longer and reduce repaint frequency, offsetting higher upfront cost.
Replacement And Repair Costs For T1-11 Siding
If your siding suffers localized damage, isolated repairs or panel replacements are feasible and affordable:
- Panel Replacement (4×8): $150 – $350 installed for one sheet, including trim/paint blending
- Patching/Repair: $60 – $200 per job for rot repair or a small patch
Whole house replacement of T1-11 siding is calculated similarly to new installation but may include removal and disposal fees of old panels, adding $0.50 – $1.00 per square foot to project costs.
Cost Of Permits And Compliance
Some municipalities require a building permit, even for siding replacement. Permit fees usually cost $50 – $300 depending on project size and local regulations. Homeowners’ associations (HOA) may require approved colors or textures, potentially influencing finishing costs.
Hidden Costs To Consider
- Wall Repairs: Uncovering rot or insect damage during tear-down may add $250 – $1,000+ for needed repairs.
- Flashing Replacement: Old or rusted flashing should be replaced for $1.00–$2.00 per sq. ft. for improved moisture defense.
- Upgrades: Improved underlayments, foam panels for insulation, or decorative trim can further raise price but boost energy savings and curb appeal.
Cost-Saving Tips For T1-11 Siding Projects
- Buy panels in bulk if possible to secure discounts from lumberyards.
- Choose OSB over plywood when acceptable for outbuildings to save money.
- Prime and paint panels before installation for more even coverage and better edge protection.
- Obtain 3 or more contractor bids and verify references to optimize your investment.
- Schedule work in contractor off-season (fall or early winter) for potential labor discount.
How Long Does T1-11 Siding Last?
T1-11 siding can last from 15 to 30 years with proper installation, high-quality paint or stain, and diligent maintenance. Wet or humid climates demand closer attention and regular recoating to prevent rot and surface splitting.
Frequently Asked Questions About T1-11 Siding Costs
Is T1-11 Siding Good For Houses Or Just Sheds?
T1-11 is commonly used for sheds, barns, and outbuildings, but it is also found on homes seeking a rustic aesthetic. Building codes may require specific grades, thicknesses, or fire treatments for residential use.
