Your Best Guide to Overhauling Period Metal Windows – and Recognising Potential Issues

by | Mar 15, 2021 | DIY Tips

There are many reasons why historical properties are seen as beautiful structures that should be carefully maintained and preserved. For one, they have their significance in our history, and they are evidence of a specific period of time and the way of life that people had. They are also a wonderful tribute to the craftsmanship and expertise of tradesmen and builders, and when these historical and period properties are well-preserved, they are a true delight to those who see them – especially to those who reside in them. But one particular element that lends an even greater charm to any period structure is the windows, and traditional or historic windows should be properly cared for as well. But how can you make sure your traditional windows are properly maintained – and, more importantly, how can you recognise issues and address them before they become bigger problems? Here’s your best guide to overhauling period metal windows and recognising potential issues.

Recognising issues with old metal windows

First of all, you need to know the type or kind of metal that is used for the actual window, whether it’s ferrous or non-ferrous. Ferrous metals are comprised of metals like iron or steel, and non-ferrous metals are comprised of aluminium and bronze. When you know the kind of metal the window has, this will help you determine the right kind of treatment as well. But there are problems that are common to all kinds of metal windows, too.

One potential problem is structural movement that can deform the opening, which also damages the window. It’s important to note, though, that some structural movements may already be so old that they have already been repaired or stabilised on their own, which enables the window to still work and function. But you should also watch out for evidence that the pointing located between the window frame and the opening on the wall is loose, missing, or cracked, which will then allow moisture to come in around the frame. Another issue is the corrosion of frames or rusting, and you should check for frame distortion as well. If the casement doesn’t seem to move properly, this could be another issue caused by excessive paint buildup, failed fittings and hinges, or frame distortion or rust.

The good news is that if there are any issues like the above on your metal windows, a good window specialist such as, that is also an expert in Crittall replacement, can address the problem and restore your windows to their past glory.

Overhauling period metal windows

When you have your period metal windows restored or overhauled, this can correct any defects resulting from standard wear and tear and corrosion. Overhauling often includes freeing casements that are jammed and removing paint buildup which can interfere with the window’s operation, and it also includes replacing defective putty and broken glass. An overhaul also includes repairing and cleaning ironmongery as well as replacing items that are missing.

With an overhaul or restoration, sticking casements and sashes can also be eased, and painted window surfaces can be prepared and redecorated. A good specialist in overhauling and restoration will also rub down areas with corroded steel and then treat them with a metal primer with zinc prior to repainting.
