• Drafts, difficulty opening or closing, condensation between panes, rising energy bills, or rotted frames are all signs. If your windows are 15–20 years old, it may be time for an upgrade.

Most windows last 15 to 25 years, depending on the material and quality. Vinyl and fiberglass windows often outlast wood or aluminum with proper maintenance.

Lower energy bills, better insulation, noise reduction, UV protection, and improved home value. New windows also enhance curb appeal and overall comfort.

• New construction windows are installed during building or full-frame remodels—ideal when studs are exposed.

• Replacement windows fit into existing frames—quicker, less invasive, and great for most window upgrades.

Low-E (low-emissivity) glass has a thin, invisible coating that reflects heat while letting in light. It helps keep your home cooler in summer and warmer in winter, improving energy efficiency.

• Argon is a non-toxic, inert gas used between double or triple window panes. It reduces heat transfer better than air, boosting insulation and reducing your energy costs.

A double-pane window has two layers of glass with air or gas between them. It insulates better than single-pane windows and helps with energy efficiency, noise reduction, and comfort.

• U-Factor (lower = better insulation)

• SHGC (lower = less solar heat gain)

• Visible Transmittance (VT) (how much light comes in)

• ENERGY STAR® label (meets efficiency standards for your region)

• U-Factor measures heat transfer—lower numbers mean better insulation. In hot climates like San Antonio, look for U-factors below 0.30 for best performance.

SHGC measures how much solar heat enters your home. Lower SHGC means better heat resistance—key for staying cool in sunny climates. Ideal SHGC is below 0.25 in hot areas.
