This is a real project. A homeowner in Sterling, VA reached out to Milcon after spending two years thinking about replacing their siding, watching the original vinyl panels fade, warp at the corners, and pull away from the trim around the garage. They had collected three quotes, done their research on James Hardie fiber cement siding, and decided they wanted it done properly. This post documents exactly what happened from the first call to the final walkthrough.

The Problem: What the Old Siding Looked Like
The homeowner’s original vinyl siding in Sterling had reached the end of its practical service life – not structurally failed, but cosmetically and functionally deteriorated in ways that were becoming increasingly difficult to ignore.
What we found during the assessment:
- Significant fading across all south-facing elevations: the original beige tone had bleached to an uneven chalky white on the sun-exposed walls while the north-facing walls retained the original colour, creating a visually mismatched exterior
- Warping and buckling at the corner joints: vinyl expands and contracts with temperature changes; after 18 Northern Virginia winters and summers, several corner pieces had pulled away from the wall and were no longer flush
- Moisture infiltration behind the lower panels: during our assessment we found two areas on the rear elevation where water had been working its way behind the siding and into the wall sheathing. Caught early, this was repairable; left another season it would have become a structural issue
- Cracked panels around the garage bay opening: impact damage from a minor vehicle incident had cracked two panels. Vinyl panel matching after 18 years of weathering is nearly impossible, leaving visible patch repairs
- Outdated appearance: beyond the functional issues, the home simply looked dated. The neighbourhood had seen significant renovation activity and the exterior had fallen behind the standard of surrounding properties
Why This Homeowner Chose James Hardie Over Vinyl
The homeowner had already made this decision before contacting us, their research had led them to James Hardie Hardie Plank and they were not looking to be talked out of it. But the reasoning is worth documenting because it is the same logic most Northern Virginia homeowners arrive at when they research siding options seriously.
The decision came down to four factors:
1. Longevity in Northern Virginia’s climate
Vinyl siding’s primary vulnerability in this region is its thermal expansion in summer heat and brittleness in winter cold. After 15 to 20 years, those repeated cycles show. James Hardie fiber cement does not expand and contract in the same way. It is dimensionally stable across temperature ranges, which is why properly installed Hardie holds its appearance and structural integrity significantly longer in Northern Virginia conditions.
2. Fire resistance
Hardie is a non-combustible material, it will not ignite or contribute to the spread of fire. Vinyl, by contrast, melts under high heat. For a homeowner in a neighbourhood with closely spaced houses, this was a meaningful factor rather than an abstract one.
3. Paint retention and appearance over time
The homeowner specifically chose ColorPlus Technology, Hardie’s factory-applied baked-on finish, after reading that it carries a 15-year fade and peel warranty from the manufacturer. They had painted their current home’s trim twice in 18 years and did not want to be back on a ladder in 8 years. ColorPlus is not field-applied paint – it is baked on at the factory under controlled conditions and performs accordingly.
4. Resale value
With a home valued in the $640,000+ Sterling market, the homeowner was conscious of maintaining the property’s position relative to the neighbourhood. Real estate agents and appraisers consistently note James Hardie siding as a premium finish that commands recognition at sale. The upfront cost premium over vinyl narrows significantly when amortised over the product’s 40+ year service life.
The Installation: Day by Day
Here is how the project progressed across the four days on site. This is what a proper James Hardie siding installation in Sterling, VA looks like when done to manufacturer specification by an Elite Preferred Contractor.
Day 1 – Full removal and substrate inspection
The crew removed all existing vinyl siding, vinyl trim, and corner pieces from the full exterior. Once the walls were stripped, Matt Kavanah conducted a full substrate inspection, checking every section of wall sheathing for moisture damage, rot, and structural integrity.
Two areas on the rear elevation showed early moisture damage as identified during the assessment, both were remediated with new OSB sheathing before any new material went on. The homeowner was shown the damaged sections before replacement. All removed material was loaded and hauled off site the same day.
Day 2 – Moisture barrier and first elevation
A new house wrap / moisture barrier was installed across the full exterior, this is a required step per James Hardie’s installation specification and is essential in Northern Virginia’s humid climate to prevent condensation from working behind the siding. The front elevation was fully sided with HardiePlank 6.25″ lap boards in Iron Gray ColorPlus, starting at the base and working upward with consistent exposure maintained throughout.
Day 3 – Remaining elevations and gable ends
The side and rear elevations were completed, including the two gable ends. The gable areas used the same HardiePlank profile as the main walls, a deliberate choice by the homeowner for visual consistency rather than switching to HardieShingle on the gables, which would have been an equally valid option.
All cuts were made off the wall and primed with James Hardie’s recommended primer at cut edges, a step that maintains the moisture resistance of the cut boards and is required to maintain the product warranty but is frequently skipped by less diligent contractors.
Day 4 – HardieTrim, caulking, touch-up, and final inspection
HardieTrim boards were installed at all windows, doors, corners, soffit returns, and the garage surround using Hardie’s proprietary trim system, not substitute PVC or wood trim. All joints between trim and siding, and all penetrations, were caulked with a manufacturer-compatible sealant. ColorPlus touch-up paint was applied to all cut edges and fastener locations.
Matt conducted the final walkthrough with the homeowner before the crew left site, walking the full perimeter, checking every elevation, every window reveal, and every corner detail. A magnetic nail sweep of the driveway and lawn was completed before departure.
The Result
The transformation was significant. The home went from a dated, uneven exterior with visible wear to a sharp, contemporary finish in Iron Gray with Bright White trim, a combination that has become one of the most popular exterior colour choices in Northern Virginia and suits the colonial roofline particularly well.
What the homeowner said:
“We knew what we wanted going in but we did not know if the end result would look the way we had imagined. It exceeded what we pictured. The trim detail around the windows especially, it looks like a completely different house. Matt walked us through everything on the last day and we could see the care that had gone into it. Exactly what we were hoping for.”
