FAQs
Q1: What is the difference between T1-11 and James Hardie siding?
T1-11 is a plywood-based panel siding that costs $3–$6 per square foot installed, while James Hardie is a fiber cement siding costing $10–$16 per square foot. James Hardie lasts 30–50 years vs. T1-11’s 15–25 years, is non-combustible (Class A fire rating) vs. T1-11’s combustibility, and resists moisture, rot, and termites — problems that commonly affect T1-11 panels in Northern California’s climate.
Q2: Is T1-11 siding good for California homes?
T1-11 siding has significant drawbacks for California homes. It is combustible (not suitable for wildfire zones or WUI areas), susceptible to moisture damage and rot without regular maintenance, and prone to termite damage. Many California homeowners are replacing T1-11 with James Hardie fiber cement siding for its fire resistance, durability, and lower long-term maintenance costs.
Q3: How much does it cost to replace T1-11 with James Hardie siding?
Replacing T1-11 with James Hardie siding costs $12–$18 per square foot in Northern California, including removal of old T1-11 panels, any sheathing or moisture barrier repairs, and installation of new HardiePlank with ColorPlus Technology. For a 2,000 sq ft home, expect $24,000–$36,000. Heritage Exteriors offers financing options to help manage the investment.
Q4: Can you install James Hardie siding over T1-11?
Installing James Hardie siding directly over T1-11 is generally not recommended. Best practice is to remove the T1-11 panels, inspect the wall sheathing and moisture barrier, make any necessary repairs, then install James Hardie over a proper weather-resistant barrier. Installing over damaged or moisture-compromised T1-11 can trap moisture and void warranties.
Q5: How long does T1-11 siding last compared to James Hardie?
T1-11 plywood siding lasts 15–25 years with regular maintenance including painting every 3–5 years, caulking, and prompt repair of any moisture damage. James Hardie fiber cement siding lasts 30–50 years with minimal maintenance — typically just occasional cleaning and touch-up painting every 15+ years with ColorPlus Technology. James Hardie costs more upfront but has a significantly lower lifetime cost of ownership.
Q6: Is James Hardie siding worth the extra cost over T1-11?
Yes, James Hardie siding is worth the higher upfront cost for most homeowners. Over a 30-year period, James Hardie’s total cost of ownership is typically lower than T1-11 when you factor in T1-11’s frequent repainting ($3,000–$5,000 every 3–5 years), repair costs from moisture/termite damage, and shorter replacement cycle. James Hardie also adds 3–5% more to home resale value than T1-11.
Q7: Is T1-11 cheaper than James Hardie?
Yes, T1-11 plywood panels have a significantly lower upfront material and installation cost ($3–$6 per square foot) compared to James Hardie fiber cement ($10–$16 per square foot). However, when calculating the new siding cost in Northern California, T1-11 often proves more expensive in the long run. Regular painting requirements ($3,000–$5,000 every few years) and inevitable repairs from moisture or pest damage quickly close the cost gap over time.
Q8: How long does T1-11 last vs Hardie?
T1-11 siding typically lasts 15 to 25 years, but only if it receives meticulous maintenance. By contrast, James Hardie siding is built to last 30 to 50 years. Because fiber cement doesn’t warp, rot, or crack under extreme weather variations, it stands out as a far more resilient option and is widely considered the best siding for the California climate.
