Complete James Hardie HardiePlank Cedar Mill Installation | Comprehensive Sherwin Williams Super Paint System









This Round Rock residence underwent a comprehensive siding upgrade featuring James Hardie HardiePlank Select Cedar Mill in 8.25-inch planks, specifically chosen for its superior performance in Central Texas climate conditions. The installation included new 7/16-inch OSB wall sheathing for enhanced structural integrity and moisture protection. Our crew meticulously wrapped the split double garage door jambs to create clean, finished edges that integrate seamlessly with the new fiber cement siding. The cedar mill texture provides the authentic wood appearance homeowners desire while delivering James Hardie's renowned durability against hail, heat, and humidity common in the Round Rock area.

The exterior painting phase utilized Sherwin Williams Super Paint across all exterior surfaces, including the new siding, existing fascia and soffit areas up to 24 inches, both garage doors, and decorative shutters. This premium paint system was selected for its exceptional adhesion to fiber cement substrates and proven longevity under Texas sun exposure. Our team carefully coordinated the paint application with the siding installation timeline to ensure optimal surface preparation and curing conditions. The comprehensive paint coverage creates a unified exterior appearance while providing an additional protective barrier against moisture infiltration and UV degradation throughout Round Rock's demanding seasonal weather patterns.

The homeowner contacted Austin Pro in December 2023 as a previous customer, already familiar with our quality workmanship and reliability. This existing relationship streamlined the initial consultation process, allowing us to focus immediately on their specific siding and painting needs. We scheduled the preliminary assessment for December 8th to evaluate the current exterior condition and discuss their renovation goals.
Our comprehensive evaluation revealed aging siding materials showing typical Central Texas weather damage, including cedar pollen staining and heat-related deterioration. We identified the need for new wall sheathing in several areas and noted the split double garage door configuration would require custom jamb wrapping solutions. The assessment confirmed both siding replacement and complete exterior painting would be necessary for optimal results.
The planning phase extended through winter months, allowing careful material selection and timeline coordination. We finalized the James Hardie HardiePlank specification and Sherwin Williams Super Paint system by February 13, 2024, when the homeowner approved the comprehensive scope. Material ordering through our supplier network ensured everything would arrive on schedule for spring installation.
Installation began in spring 2024 with structural preparation including new OSB wall sheathing where needed. Our crew methodically installed the James Hardie siding with precise attention to fastening and flashing details, followed by the comprehensive Sherwin Williams painting phase. The split timeline allowed optimal weather conditions for both siding and coating applications.
Final completion occurred July 3rd, 2024, followed by our detailed walkthrough with the homeowner on July 9th. The project delivered exactly the transformation they envisioned - superior weather protection combined with enhanced curb appeal. We completed final invoicing July 25th with full warranty coverage for both the James Hardie siding and Sherwin Williams paint systems.
This Round Rock homeowner contacted Austin Pro as a previous customer, understanding the quality and reliability our team delivers for exterior renovations. Their home required both new siding and comprehensive exterior painting to address aging exterior materials that were showing wear from Central Texas weather exposure.
During our December 2023 evaluation, we identified several key issues requiring attention. The existing siding showed typical deterioration patterns common in Round Rock's climate, with cedar pollen staining and heat-related expansion damage. The split double garage door configuration presented unique trim challenges that would require custom jamb wrapping solutions. Our assessment revealed the need for new wall sheathing in several areas to ensure proper substrate preparation for the James Hardie installation.
The homeowner's timeline allowed for careful planning through winter months, with installation scheduled to avoid the peak summer heat that can complicate both siding and painting phases.
Siding Solution: We specified James Hardie HardiePlank Select Cedar Mill in 8.25-inch planks for this project. This fiber cement siding offers the authentic wood texture the homeowner preferred while providing superior resistance to hail damage, moisture infiltration, and UV exposure common in the Austin metro area. The cedar mill profile creates attractive shadow lines that enhance the home's architectural character.
Paint System: Sherwin Williams Super Paint was selected for all exterior surfaces. This premium coating system provides excellent adhesion to fiber cement substrates and exceptional color retention under intense Texas sun exposure. The comprehensive scope included:
Phase 1: Structural Preparation Our crew began with careful removal of existing siding materials and assessment of underlying sheathing. We installed new 7/16-inch OSB wall sheathing where needed to create a solid, moisture-resistant substrate. This step proved crucial for long-term performance, especially given Round Rock's occasional severe weather events.
Phase 2: Siding Installation The James Hardie HardiePlank installation required meticulous attention to manufacturer specifications for fastening, spacing, and flashing details. Our team wrapped the split double garage door jambs with matching trim to create seamless transitions between the new siding and existing architectural elements. Each plank was precisely measured and cut to maintain consistent reveal lines across all elevations.
Phase 3: Surface Preparation and Painting Proper surface preparation proved essential for paint adhesion and longevity. Our crew primed all new fiber cement surfaces according to Sherwin Williams specifications, ensuring optimal bonding between substrate and finish coating. The Super Paint application included two full coats on all specified surfaces, with careful attention to coverage uniformity and proper drying time between coats.
The project timeline reflected our commitment to quality execution:
This extended timeline allowed for optimal weather conditions during both siding and painting phases, crucial for achieving the best possible results with both James Hardie fiber cement and Sherwin Williams coatings.
The completed project transformed this Round Rock home's exterior appearance while significantly improving its weather resistance and energy efficiency. The James Hardie siding provides decades of protection against hail, high winds, and moisture infiltration common in Central Texas. The coordinated Sherwin Williams paint system enhances both aesthetics and performance, with superior fade resistance that maintains curb appeal for years to come.
The custom garage door jamb wrapping creates clean, finished edges that integrate seamlessly with the overall design. Proper flashing and trim details ensure moisture protection at all penetrations and transitions.
This project demonstrates the value of combining premium siding and painting systems for comprehensive exterior protection. Round Rock's location exposes homes to intense summer heat, occasional hail events, and persistent cedar pollen - conditions that quickly deteriorate lower-quality materials.
The James Hardie and Sherwin Williams combination provides proven performance in our local climate, backed by comprehensive warranties and our commitment to professional installation. Homeowners considering similar upgrades benefit from Austin Pro's experience with these specific products and local weather challenges.
Our team's familiarity with Round Rock building codes, typical architectural styles, and climate considerations ensures each project meets both aesthetic goals and long-term performance requirements.
