Complete James Hardie Select Cedar Mill 8.25" Fiber Cement Siding Installation | Double-Layer Tear-Off With New 7/16" OSB Sheathing and Sherwin Williams Finish
This full siding replacement in Austin, TX used James Hardie fiber cement in the Select Cedar Mill 8.25" lap profile. We tore off two layers of failing siding, installed 7/16" OSB wall sheathing, and hung the new boards. New Hardie fascia and soffit tied the trim together. Fiber cement was chosen because it shrugs off 100°+ summers, hail, and moisture better than wood.

The exterior painting component featured Sherwin Williams Super Paint Exterior applied to all new siding, fascia, and soffit surfaces using professional-grade application techniques. This premium coating system was chosen for its exceptional resistance to Austin's intense summer heat and UV radiation, which can quickly degrade lesser paint products. The paint application process was carefully coordinated with the siding installation to ensure proper adhesion and coverage across all surfaces, including the detailed fascia work ranging from 25 to 36 inches and open soffit areas that require specialized attention.
The homeowner found Austin Pro through an internet search and reached out on June 16, 2025. The first conversation focused on the aging, moisture-damaged siding and what a full replacement would involve.
We inspected the exterior in mid-July 2025 and moved the job to prospect on July 14. The assessment flagged two hidden layers of old siding, soft sheathing, and early rot in the fascia trim.
We built a scope covering tear-off, new sheathing, James Hardie siding, and fascia and soffit work. The homeowner approved the project on August 5, 2025, and we scheduled material delivery through ABC Supply.
On November 12, 2025, the crew completed the full install in one day. That included a double-layer tear-off, new 7/16" OSB sheathing, Select Cedar Mill lap siding, fascia and soffit, plus an electrical mast detach and reset by a licensed electrician.
We invoiced and completed the job the same day, November 12, 2025, after painting the siding, fascia, and soffit with Sherwin Williams Super Paint. Two yard cleanups and a punch-out closed the site, and the file formally closed on April 2, 2026.
We replaced every board of siding on this Austin home in the 78723 area, tearing off two failing layers and installing James Hardie fiber cement finished in Sherwin Williams paint. The house went from soft, rot-prone walls to a hard, weather-tight shell in a single work day.
The old siding had reached the end of its life. Years of hard summers and spring hail left it soft, cracked, and letting moisture reach the wall behind it. This 78723 home sits in an established Austin neighborhood where 1980s and 1990s builds are common.
The tear-off told the real story. Under the top layer sat a second, older layer of siding, so we ran a double-layer tear-off to get down to the studs. That extra step matters, because you can never trust siding installed over a hidden problem.
What we found underneath was sheathing past its prime. Rather than reuse it, we installed new 7/16" OSB wall sheathing across the whole home. Fresh sheathing gives the fiber cement a flat, sound surface to fasten to, and it seals up gaps where Austin's wind-driven rain used to sneak in. Skip this step and even the best siding will telegraph every dip and soft spot behind it.
We went with James Hardie Select Cedar Mill 8.25" lap siding. It carries the look of real cedar grain but won't warp, swell, or feed the rot that plagues wood in our climate.
Fiber cement earns its keep in Central Texas. It holds up to 100°-plus summers without buckling, takes hail far better than wood or vinyl, and doesn't soften when cedar pollen and spring storms settle into the seams.
The crew ran the full scope in a single day on November 12, 2025. Tear-off, sheathing, siding, fascia, and soffit all moved in sequence so no wall sat open overnight.
The walls, trim, and eaves now read as one clean, painted surface. We finished the siding in Sherwin Williams Super Paint, which locks color into the fiber cement and stands up to UV.
It resists the three things that wreck exteriors here: extreme heat, hail impact, and moisture in the seams. Unlike wood, it won't rot or attract pests, so it's a strong fit for older 78723 homes.
This retail project fell in the $25,000 to $30,000 range. That covered tear-off, new sheathing, all James Hardie material, paint, and the electrical mast work.
The install itself wrapped in one day on November 12, 2025. The larger timeline ran from the first lead in June through approval in August, with the file closing out in spring 2026.
Not for a long time. The boards were topcoated with a quality exterior paint on site, so you get years of color life before any refresh is due.
Austin Pro crafts exteriors that not only captivate but also promise steadfast protection and reliability, embodying the vibrant spirit of Austin in every facade. Your home's exterior is its silent storyteller and first impression; let us help it speak volumes without uttering a word.
