Metal Window restoration or replacement?

Older or period properties often have leaded windows (frequently termed leaded lights) that may last many years but ultimately do need restoration or repair at some stage. Traditional leaded windows are often encased in metal or crittall windows which also degrade over time and want repair. At that point a decision needs to be made whether or not to restore or replace a more modern option, for example aluminium windows. No chance however in a Grade I listed property or in some cases
Grade II.

So determining which is the best option for your property is frequently dependent on numerous factors, some of which are down to personal taste. It doesn't matter how poor the condition of the metal windows is, they are able to generally be restored. New leaded lights may also be manufactured if necessary, preserving because the old glass as possible, and replacing missing or broken panes with antique glass. Older glass is generally preferred due to the variations for the reason that (bubbles, deformity), it's these imperfections that provide the leaded window its character. When leaded lighting is being restored it is wise to consider replacing strengthening bars (if needed) and also internal strengthening from the lead (steel inserts).

If you want to preserve the look - slim metal windows with or without leads - but require less maintenance, better heat efficiency and security, then aluminium windows are a good alternative. With aluminium windows the profile is generally slim to match the look of crittall windows (as opposed to uPVC), and they are double glazed with lead look inserts. Another benefit is they can be colour matched (to the RAL type) dual colour. To help you have for instance, black on the outside and white inside, and diamond or square lead pattern within the windows to match existing.

The final area of restoration involved with metal windows is generally the timber or hardwood frames these are fitted to. Metal windows are usually fitted into hardwood frames - instead of straight into concrete in domestic homes. These may also need repair or replacement.

The normal problem however is finding a company who focuses on all types of restoration or replacement, and may give sound advice on the different options allowing the homeowner to make the best informed decision. Most glazing companies will have little interest or knowledge in restoration, preferring instead to suggest replacement windows because the only sensible option and usually uPVC. However uPVC, although inexpensive, cannot replicate the look of a metal window (whether it is crittall or aluminium) or even the security level.
