Sleek designs and updated finishes refresh exteriors, increasing value in Herndon’s competitive housing market.
Noise Reduction:
Advanced multi-pane glass dampens airplane noise from Dulles Airport and traffic along Route 28.
UV Protection:
Low-E coatings block harmful rays, preserving furniture, flooring, and artwork without dimming natural light.

Tilt-in sashes and durable materials simplify cleaning and extend the life of your investment.

Signs It’s Time for Window Replacement

Failing windows create compounding problems over time. Signs you may need Herndon window replacement include:

Drafts or Cold Spots:
Air leaks make interiors uncomfortable and drive up heating and cooling bills.
Sticky or Warped Frames:
Windows that won’t open or close properly often indicate water damage or structural failure.
Condensation Between Panes:
Fogging between glass layers signals broken seals and lost efficiency.
Noticeable Outside Noise:
If you can easily hear exterior sounds from flights or traffic, your windows are no longer providing adequate insulation.

Popular Window Frame Materials to Use in Herndon

Vinyl

Affordable, low-maintenance, and efficient, vinyl windows are a popular choice for Herndon’s single-family homes and multifamily communities. They come in a wide range of styles and colors to match any property.

Fiberglass

Known for durability and excellent thermal performance, fiberglass windows resist warping and swelling in Virginia’s changing seasons. They’re ideal for both long-term multifamily projects and homeowners who want strength and style.

Wood

Perfect for preserving the traditional character of Old Town Herndon, wood windows offer unmatched charm and natural insulation. While they require somewhat regular maintenance, they remain a staple for historic properties.
