Full James Hardie Cedar Mill 8.25" Lap Siding Installation | NT Windows Replacement With New OSB Sheathing
This Manor project replaced aging cladding with James Hardie fiber cement siding. We used the Primed Select Cedar Mill 8.25" lap profile over all-new 7/16" OSB wall sheathing. Fiber cement was chosen because it shrugs off hail, heat, and cedar pollen better than wood. A Sherwin Williams Super Paint finish sealed the siding, fascia, and soffit for lasting protection.

New replacement windows were installed across the home ahead of the siding work. The units came through NT Windows, sized to the existing openings for a clean fit. Setting the glass first let the crew flash and integrate each window with the new sheathing. That sequence keeps water out and holds cooled air in through brutal summers.
The homeowner found Austin Pro through an internet search and reached out on February 13, 2025. The first conversation covered worn siding and dated windows on their Hogeye home. We set up a site visit to see the full exterior in person.
During the assessment, we inspected the cladding, sheathing, fascia, and soffit along with every window opening. The old walls showed hail damage and sun wear, and the sheathing was soft in places. By March 3, 2025, the project moved from lead to active prospect with a clear scope forming.
We walked the homeowner through James Hardie Cedar Mill options, NT Windows units, and a Sherwin Williams color plan. Material and delivery were coordinated through ABC Supply Co. and Garrett James. The homeowner approved the full plan on May 12, 2025.
The crew completed the work on August 21, 2025. Windows went in first, followed by new 7/16" OSB sheathing, then the 8.25" Cedar Mill lap siding. Painters finished the siding, fascia, soffit, and three exterior doors before punch-out.
After a full walkthrough and two yard cleanups, the punch list was cleared the same day the job invoiced. The finished exterior gave the home a fresh, weather-ready envelope. The project file closed on September 9, 2025.
We replaced every window and re-clad the entire exterior of a home in Hogeye, Manor, TX, swapping old cladding for James Hardie fiber cement. The finished house is tighter, tougher, and built for Central Texas weather.
The old cladding had taken years of Central Texas abuse. Between hail hits, cedar pollen buildup, and summers over 100 degrees, it was worn past the point of patching.
Pulling the old siding told the real story. The sheathing underneath had softened in spots, so we didn't gamble on it. We installed brand-new 7/16" OSB wall sheathing across the whole home before a single board of siding went up. That extra step matters here. Manor's limestone soil and heat cycles put constant stress on a wall assembly, and a solid, uniform substrate is what keeps fiber cement flat and fastened for decades. Skipping it is the most common shortcut we see, and it always comes back to haunt the homeowner.
We chose the Primed Select Cedar Mill 8.25" lap because it delivers a real wood-grain look without wood's weaknesses. Fiber cement won't rot, warp, or feed the moisture that cedar pollen loves to trap.
Sequence is everything on a combined job. We set the new windows through NT Windows before the siding, so each unit could be flashed and sealed against the fresh sheathing. Doing it in that order stops water from ever sneaking behind the cladding. It also means the siding laps neatly over the window flanges instead of butting awkwardly against them. A homeowner who reverses this order often ends up with leaks at the corners and no easy way to fix them. Tight, well-flashed windows also hold cooled air inside through the worst of an Austin-area summer.
With planning done, the crew handled the full scope in a focused push on August 21, 2025. Windows went in, then sheathing, then siding, then paint and punch-out.
The lead came in on February 13, 2025, and the homeowner approved the plan on May 12. Field work wrapped on August 21, 2025, with the file closed on September 9.
Yes. Fiber cement stays dimensionally stable when temperatures push past 100 degrees, unlike wood that swells and shrinks. It also stands up to hail and won't rot in humid stretches after storms.
This full siding-and-window project landed in the $50k–$60k range. That covered new sheathing, James Hardie lap siding, replacement windows, and a complete paint finish including three doors.
Primed board is ready for paint but not weatherproof on its own. The Sherwin Williams Super Paint topcoat seals the surface, locks in color, and adds another shield against Central Texas sun and rain.
