Housing stock in this part of Lancaster has unique traits. Quite a few homes have had their original front bay altered structurally at some point, so a "like-for-like" replacement isn't always possible without minor adjustment.

Before You Decide
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.
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.
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.
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.
