T1-11 siding is a type of plywood or engineered wood siding that has been used on homes for decades. It is known for its textured surface that mimics vertical wood planks, giving homes a rustic, natural appearance. Homeowners often choose T1-11 because it is affordable, easy to install, and customizable with paint or stain. However, like any exterior siding, T1-11 wears down over time, especially when exposed to moisture and harsh weather.
When T1-11 siding begins to rot, crack, or warp, replacing it becomes essential to protect your home’s structure and maintain its curb appeal. Understanding the cost to replace T1-11 siding helps homeowners plan their budgets, compare material and labor expenses, and evaluate whether to stick with T1-11 or switch to lower-maintenance siding options like vinyl or fiber cement.
This article breaks down the average costs to replace T1-11 siding, covering factors that affect pricing, common challenges, and expert insights to help homeowners make informed decisions.
Factors Affecting the Cost to Replace T1-11 Siding
The cost to replace T1-11 siding varies widely based on several factors. Materials, labor, home size, and the condition of the existing siding all contribute to the final project cost. Understanding these factors helps homeowners plan accurately and avoid unexpected expenses.
Material Costs
Material selection significantly impacts the overall cost of replacing T1-11 siding. Traditional T1-11 plywood siding costs between $2.00 and $4.00 per square foot, while engineered wood T1-11 panels tend to range from $3.50 to $7.00 per square foot.
Plywood T1-11 panels are made from multiple layers of thin wood veneers, while engineered T1-11 uses wood strands and resins to create a denser, more moisture-resistant product. Engineered panels typically cost more upfront but offer better durability, especially in humid or rainy climates.
In addition to the panels themselves, replacement projects often require house wrap, flashing, nails, caulk, and paint or stain, which add to the material costs. Pre-primed panels reduce finishing expenses but increase initial purchase prices. For homeowners considering an upgrade, comparing T1-11 with vinyl, fiber cement, or composite siding provides insight into whether sticking with T1-11 is the most cost-effective long-term solution.
Labor Costs
Labor makes up a large portion of T1-11 siding replacement costs, particularly when old siding removal, wall repairs, and proper installation techniques are involved. On average, siding contractors charge between $40 and $70 per hour or $3.00 to $7.00 per square foot for labor alone.
Labor rates vary by region, with urban areas and regions with high demand for skilled trades seeing higher hourly rates. Factors like home height, complex architectural features, and the need for scaffolding can also drive up labor expenses.
T1-11 siding installation is generally faster than materials like fiber cement, but ensuring panels are correctly sealed, fastened, and finished adds to labor time. Hiring licensed and insured contractors helps protect homeowners from liability and ensures proper installation that meets building codes.
Home Size and Siding Area
The size of the home directly affects the cost to replace T1-11 siding, as larger homes require more materials and labor. Most siding is priced and estimated by square footage, so accurately calculating the total exterior surface area is essential for budgeting.
For a 1,500 square foot home, replacing T1-11 siding typically costs between $7,500 and $15,000, depending on material quality, labor rates, and other project variables. Smaller homes with fewer exterior walls fall toward the lower end of the range, while larger homes with complex architectural details, multiple stories, or detached garages incur higher costs.
In addition to overall square footage, features like bump-outs, dormers, porches, and gables increase the amount of siding needed and add to labor complexity.
Extent of Damage or Repairs Needed
The condition of the existing siding and the underlying wall structure has a major impact on replacement costs. If the T1-11 siding has only cosmetic wear, the project may involve simple removal and replacement. However, if moisture infiltration has caused rot, mold, or structural damage to the sheathing or framing, repair costs quickly escalate.
Rot repair can add $500 to $3,000 or more to a siding replacement project, depending on the extent of damage. Areas with chronic water exposure, such as near windows, doors, or rooflines, are common trouble spots.
If the project involves upgrading the home’s moisture barrier, adding house wrap or improved flashing can add $0.50 to $2.00 per square foot, but this step enhances durability and protects the new siding investment.
Permits and Inspections
Most jurisdictions require permits for exterior siding replacement, particularly if structural repairs, insulation upgrades, or wall modifications are involved. Permit fees vary by location but typically range from $50 to $300, depending on the scope of work and local regulations.
In areas with strict building codes, inspectors may need to review moisture barriers, flashing installations, and fastening methods before the final inspection. Homes in historic districts or neighborhoods with homeowners’ associations may also require design approval or specific material choices, which can influence project costs and timelines.

Cost-Saving Tips for Replacing T1-11 Siding
Replacing T1-11 siding can be a significant expense, but there are several ways homeowners can reduce costs without compromising quality. From choosing the right materials to timing the project strategically, these cost-saving tips can help manage your budget more effectively while ensuring your home’s exterior remains durable and attractive.
Get Multiple Quotes from Contractors
One of the most effective ways to save money is to obtain estimates from at least 3 licensed contractors. Comparing quotes allows homeowners to understand the average cost in their area and identify potential overcharges or unnecessary add-ons.
When reviewing quotes, it’s essential to look beyond the bottom-line price and evaluate the materials used, warranties offered, and the contractor’s reputation. In some cases, a slightly higher quote from a highly reputable contractor can save money in the long run by reducing repair and maintenance costs.
Consider Partial Replacement Instead of Full Replacement
If only certain areas of your T1-11 siding show signs of rot, warping, or moisture damage, a partial replacement may be possible. Replacing only the damaged panels while leaving intact ones in place can reduce material and labor costs.
However, this approach works best if the new panels can be matched in appearance and size to the existing siding. This option is particularly viable if the damage is limited to one side of the house, such as a shaded north-facing wall or an area near a leaking gutter.
Choose Cost-Effective Materials and Finishes
If your goal is to save money upfront, selecting a lower-grade T1-11 panel may reduce the material cost. Standard T1-11 made from plywood is typically cheaper than oriented strand board (OSB) T1-11 with a premium finish.
Additionally, opting for factory-primed panels can save on priming labor costs during installation. Homeowners can also choose a solid color stain, which may require fewer coats than paint, saving on both materials and labor.
Plan the Project During Off-Peak Seasons
Contractors are often busiest during spring and early summer. Scheduling siding replacement during the late fall or winter months could result in lower labor rates because demand is lower. Many contractors offer off-season discounts to keep their crews working year-round.
However, this approach depends on local climate conditions. In colder regions, replacing siding during the peak of winter may not be feasible due to weather limitations, so aim for early fall or late winter when temperatures are milder.
Take Advantage of Rebates and Incentives
In some areas, local governments, utilities, or environmental programs offer rebates for installing energy-efficient house wraps or using sustainable materials during siding replacement. Check with your municipality or state energy office to see if any financial incentives are available for projects that improve your home’s energy efficiency or reduce environmental impact.
Conclusion
Replacing T1-11 siding is a necessary investment to protect your home’s structure, improve curb appeal, and enhance energy efficiency. While costs vary based on factors like material quality, labor rates, and home size, understanding these elements helps homeowners budget more effectively.
Exploring alternative siding options, comparing contractor quotes, and choosing cost-saving strategies can make the project more affordable without compromising quality. Whether you decide to replace your T1-11 siding with the same material or upgrade to a more durable alternative, timely replacement ensures your home stays protected from moisture, pests, and weather damage for years to come.
