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.
