Double Glazing Repair & Glass Replacement in Greater London

Determining whether your double glazing needs repair or replacement depends on several factors. If you notice condensation or fogging between the panes, it usually indicates a failed seal, and the unit may need replacing. If the glass is cracked, shattered, or broken, it requires immediate replacement. Additionally, if your windows are difficult to open or close, drafty, or if you notice significant heat loss, repairs or replacement might be necessary. An experienced glazier can assess the condition of your units and advise whether repairs—such as resealing—are sufficient or if full replacement is the best solution for long-term performance.

Misted or fogged double-glazed units occur when the seal between the panes fails, allowing moisture to enter. While minor misting can sometimes be addressed with re-sealing or repairs, in most cases, the best long-term solution is to replace the entire unit. We offer professional replacement of misted double-glazed units, restoring clarity, insulation, and energy efficiency. Repairing the seal alone is often temporary, as the moisture ingress indicates the seal has failed permanently.

Double glazing consists of two panes of glass separated by a sealed air or gas-filled space. This design improves insulation by reducing heat transfer, making properties more energy-efficient. It also offers noise reduction, increased security, and protection against the elements. Double-glazed units are commonly used in residential and commercial windows to enhance comfort and reduce energy bills.

Yes, we specialize in replacing misted or fogged double-glazed units. Once the seal fails and moisture enters between the panes, the unit’s insulating properties diminish, and clarity is lost. Replacing the unit restores insulation, appearance, and energy efficiency. We can remove the faulty unit and install a new, high-quality double-glazed panel tailored to your window frame.
