Straight Talk on Common Doubts
How Urgent Is It?
Failed seals and misted units won't get better on their own and will worsen over time. Draughts and condensation also lead to damp and mould if left untreated. We recommend addressing issues promptly.
Is It Worth Replacing or Should I Wait?
If your frames are in good condition, replacing just the glass units is very cost-effective. If frames are damaged too, a full replacement is the better long-term investment.
Will It Match My Existing Windows?
Yes. We can match glass types, spacer bars and frame colours to your existing installation so repairs blend seamlessly.
Can't You Just Repair It?
Sometimes yes — we always try the most cost-effective solution first. If a seal has failed but the frame is sound, we can replace just the sealed unit. We'll always give you honest advice.
