James Hardie HardieTrim Custom Colonial Roughsawn Siding Replacement | NT Window Replacement with Sealed, Flashed Openings









This Round Rock siding project used James Hardie HardieTrim in a Custom Colonial Roughsawn look. We tore off two layers of old siding before installing the new fiber cement boards. Fiber cement holds up to 100-degree summers, hail, and cedar pollen far better than wood. We finished with Sherwin-Williams SuperPaint on the siding, fascia, and soffit for a lasting seal.

The window replacement in Round Rock came through NT Window, ordered in mid-October. The units arrived and went in during early November, ahead of the siding phase. Installing windows first let us flash and seal each opening the right way. Tight, well-sealed frames cut heat gain and keep dust and pollen out of the home.

The homeowner found Austin Pro through an internet search and reached out on September 26, 2023. We talked through the storm damage and moved the conversation into a estimating stage by September 28, 2023.
We inspected the exterior and confirmed the siding had two layers that both needed to come off. The assessment flagged worn trim and window openings that would need proper flashing, setting up the insurance scope.
The claim was approved on October 12, 2023. We finalized the James Hardie HardieTrim selection in a Custom Colonial Roughsawn profile and ordered the Executive windows through NT Window in mid-October.
Windows arrived and went in during early November, ahead of the siding phase. The crew then ran a double-layer tear-off and installed the new HardieTrim over several days, finishing with Sherwin-Williams SuperPaint on the siding, fascia, and soffit.
We completed the project on December 11, 2023, with two rounds of yard cleanup and punch-out items to close things out.
We replaced the siding and windows on a home in Avignon, Round Rock, giving it a weather-tight, freshly painted exterior built for Central Texas summers. The finished job pairs James Hardie fiber cement trim with new NT Window Executive units, all sealed and painted by December 11, 2023.
The old siding had worn past the point of patching. Under it, we needed clean sheathing before anything new could go up.
Double-layer tear-offs always tell a story, and this one did too. Peeling back both layers let us see the sheathing and framing that had been hidden for years. That step matters more than most homeowners realize. Skipping it and layering new siding over old rot just traps moisture and shortens the life of everything above it. Because we went to the studs, we could confirm the substrate was sound before the first HardieTrim board went up.
Fiber cement is the right call for this climate, and it isn't close. Round Rock homes take a beating from 100-degree heat, spring hail, and heavy cedar pollen every winter.
We ordered the windows through NT Window in mid-October, and they arrived and went in during early November. Sequencing matters here. Setting the windows first let the crew flash and seal each opening the correct way, then bring the new trim tight against finished frames. Do it in the wrong order and you get sloppy trim lines and gaps where water sneaks in. Once the openings were sealed, the siding replacement moved forward over several days, followed by paint.
After the new boards were up, we sealed the whole exterior with paint. This is what protects the fiber cement and ties the look together.
The claim was approved on October 12, 2023, and the job wrapped December 11, 2023. Windows led the way in early November, with siding and paint following over the weeks after.
Yes. This was an insurance job tied to storm damage, and it fell in the $10k–$15k range. We coordinated the tear-off and replacement scope to match the approved claim.
A fresh SuperPaint coat lets us match the home's exact color and seal every cut edge from the field work. It also refreshes the fascia and soffit so the whole exterior ages evenly under the Texas sun.
Indirectly, yes. Sealing the siding and window openings tight cuts the gaps where pollen and dust drift indoors, which is a real win during Central Texas cedar season.
