The Inspection
Before starting the replacement at this Vienna residence, our team inspected the two existing windows and surrounding structures. After removing the old units, we evaluated the rough openings and identified the need to restore the bottom framing, ensuring a solid foundation and long-term performance.
The Process
To ensure efficiency and a precise fit, we repaired the framing with pressure-treated pine and installed PlyGem 70 Pro Series double-hung vinyl windows into the existing frames. We secured them with flashing tape and shims, sealed gaps with spray foam insulation, and finished with exterior silicone and interior latex caulk for a weather-tight result.
The Result
The result is a significant upgrade in both performance and appearance, featuring high-quality white vinyl windows with black screens and classic grilles that enhance the home’s character. These new PlyGem units provide the homeowner with superior insulation and ease of operation for years to come.
