Window Replacement Services in the Lehigh Valley

Old, drafty windows are one of the biggest sources of energy loss in Lehigh Valley homes. 3 Days Later Roofing + Renovations installs energy-efficient double-pane and triple-pane replacement windows that reduce heating and cooling costs, block outside noise, and eliminate cold drafts. We carry vinyl, wood, and composite frame options from leading manufacturers to match any home style and budget.

Our window installation process is clean and efficient. We remove old windows, inspect and repair the framing, install new windows with proper flashing and insulation, and finish with interior and exterior trim. Most window replacements are completed in a single day with no damage to your walls or landscaping.

Many Lehigh Valley homes were built with single-pane or early double-pane windows that have lost their seal and insulating ability. Replacing them with modern Low-E, argon-filled windows can reduce heating and cooling costs by 10% to 25% while making your home noticeably more comfortable. We offer both insert replacements for a quick upgrade and full-frame replacements when the existing frame is damaged or you want to change the window size.
