James Hardie Siding Replacement in Louisville, CO – Completing the Hardie Look

Project Summary

WestPro replaced the siding on this Louisville, Colorado home in July 2026. We installed James Hardie 8.25-inch HardiePlank Lap Siding in Khaki Brown, paired with James Hardie 2.5-inch Batten trim in Timber Bark and new OSB sheathing where the old substrate was damaged. The project was completed over four days.

The Problem

When Dale reached out to us, his Louisville home had a mix of siding styles that no longer looked unified. Three of the four walls were already covered in Hardie board, but the final wall was still original cedar siding from when the house was built in 1980. He wanted to finish the job and update that last section to match the rest of the exterior.

The existing cedar siding had been weathering for decades and was beginning to peel and fail. The underlying wood substrate was also compromised in several areas. Because the old materials were deteriorating and did not match the newer siding on the other walls, a patch would not have provided a lasting or cohesive solution.

Why It Needed Replacing

The cedar siding on the southwest side had been weathering since the home was built in 1980, so patching it would have left the rest of the aging boards in place. Replacing the entire section with James Hardie siding and new soffit and fascia brought the exterior up to current standards and ensured a uniform look.

What We Did

We began the project by removing the existing cedar siding from the southwest side of the home. Our team replaced damaged wall sheathing with new OSB where the old substrate was compromised to create a solid base for the new materials. We then installed new drip edge along the eaves and rakes to protect the edges of the roof and walls from water intrusion.

For the siding installation we applied James Hardie 8.25" HardiePlank Lap Siding in Khaki Brown to match the homeowner's chosen color. We completed the exterior look by installing James Hardie 2.5" Batten in Timber Bark and James Hardie HardieTrim in Timber Bark for the trim and fascia work.

Project Details

This home in Louisville, Colorado, had James Hardie siding on three walls, with the project focused on replacing the siding on the fourth wall. The work covered 639 square feet of siding and 106.5 linear feet of trim. The project was completed in July 2026.

Price Context

This project's siding work was completed at approximately $9 per sq ft installed. This is the complete installed scope for the siding portion of this home, including tear-off, trim, and labor. Homeowners considering a similar James Hardie 8.25-inch HardiePlank Lap Siding in ColorPlus project in Colorado should generally expect pricing in the range of $20.00–$24.00/sq ft installed. Pricing varies based on the siding profile, the trim package, wall complexity, existing-siding removal requirements, sheathing repairs, and any soffit or fascia work bundled with the project. Sheathing condition can significantly impact cost, as replacing damaged wood with new plywood or OSB adds material and labor expenses. Single layer tear-offs are generally cleaner and faster than removing multiple layers of siding.
