Signs that your double-glazed window seals need replacing include condensation or fogging between the glass panes, drafts near the window, visible mould or discoloration around the edges, and increased energy bills due to heat loss. Damaged seals allow moisture and air to enter, undermining insulation and causing your heating system to work harder. Typically, window seals last between 10 to 20 years, but British weather can accelerate their deterioration. We recommend professional seal replacement to restore energy efficiency and comfort. Find detailed guidance on seal replacement and costs here.
Regular window maintenance at Cloudy2Clear helps reduce energy losses by up to 15%. Maintenance prevents seal degradation, drafts, and frame damage that allow heat to escape and cold air to enter your home. By inspecting and replacing worn seals, cleaning glass and frames, and lubricating hardware, we maintain your windows' insulation performance and natural light transmission. Clean windows also improve solar heat gain during winter, reducing heating needs. Scheduling annual professional inspections before winter ensures small issues are caught early, saving you money on energy bills and costly repairs.
