    Signs You Need Window or Door Replacement

    Ignoring these signs allows moisture damage to spread, leading to mold and structural issues.

    • Drafts or cold air inside – Air infiltration around frames indicates failed seals or poor insulation

    • Condensation between glass panes – Failed double-pane window seal. Glass replacement needed

    • Difficulty opening or closing – Binding, sticking, or out-of-level installation

    • Water leaks around frame – Water stains on interior walls. Flashing or sealant failure likely

    • Visible rot or damage – Cracked frames, broken glass, or damaged door panels

    • High energy bills – Heat loss through failed windows or doors. Replacement improves efficiency by 15-30%

    • Foggy or cloudy windows – Seal failure allowing moisture between panes

    👉 These indicate deeper issues — not just cosmetic problems.
