FAQ

How do I know if my window needs repairing or replacing?

Common signs include condensation between panes, drafts, difficulty opening or closing, damaged frames, and rising energy bills. We assess the condition and advise whether repair or full replacement is the most cost-effective solution.

Can you fix misted or fogged double-glazed windows?

Yes. Fogging indicates a failed seal. We replace the affected glass unit quickly without changing the entire window frame, restoring clarity and insulation.

How much does it cost to repair or replace a window in the UK?

Costs vary based on size, frame material, glazing type, and the level of damage. We provide clear, itemised quotations after a quick survey so you always know the exact price before any work begins.

Do new windows help reduce energy bills?

Absolutely. Modern A-rated double-glazed and triple-glazed windows significantly reduce heat loss, improve insulation, and help lower monthly heating costs, especially in older properties.

How long does a window installation usually take?

Most standard windows can be installed within 1–2 hours each. Larger bay, bow, or aluminium systems may take longer. We aim to complete work efficiently with minimal disruption to your home.

Do you offer emergency window repairs?

Yes. For broken glass, security risks, or urgent damage, we provide rapid-response emergency window repairs and temporary boarding to keep your property safe.
