Restoring or Replacing windows

When you observe that your windows are leaky, foggy, or cold, you might start to wonder whether to replace or restore them. Traditionally, when a window displayed any signs of damage or didn’t do its job, it was repaired. Then, more recently, the trend changed to replacing windows, particularly windows with wood frames to new and improved vinyl, fiberglass or metal options. Now, with the environmental concerns on the rise, reusing items is encouraged, and throwing away should be avoided. The question is, how can you know whether a window should be restored or replaced? Let’s find out. 

Broken or Cracked Glass

When encountering any problems with the glass in your window, like cracks or any visible breaks, you will most probably need to replace your window due to safety reasons. However, if you are the owner of single-pane windows, note that they can be repaired by a glazier. Multi-pane windows, on the other hand, when broken or cracked, can be replaced with sash windows or brand-new multi-pane windows. No matter the method, please look for a trusted glazier or window manufacture, like sash windows from east London, to ensure the safety of your house. 

High Condensation/ Water Leakage

Any form of water leakage or high condensation near the window area is a sign that suggests poor draining and damaged window seals. Water leaking inside your home can also mean problems with the exterior casing of your windows. It could result in a need to replace the casing or the seals, but it can also be  the result of issues with your exterior as a whole. Determine the source of water leakage and when it's the window itself, consider replacing it, but if it’s the draining system, restore your window and work on the exterior of the house. 

Problems with Sashes

A common problem with older windows is that both lower and upper sashes are unable to move. This could be due to too many layers of paint bridging the frame and the sash or issues with the opening mechanism. When the lower sash is difficult to raise, you might need to replace the sash weights or broken cords. Fortunately, these types of problems can be fixed, and you won’t have to replace your windows. 

Damaged Exterior Casing 

Signs of rot, cracks, or missing parts in your exterior casing can lead to window damage over time. However, the damaged casing doesn’t mean you need to visit a window-shop, you can restore the casings, or replace just this part of the window, no need for brand-new windows.  

Broken Fins or Muntins

Fins or muntins are small pieces of wood separating the panes of glass in your window. They can be faux, set between the panes of glass for effect only, and therefore impossible to replace. But if they are rotting or split, they need to be rebuilt. Contact your local glazier to determine whether it is safe to leave the fins and muntins as they are, or whether you need to start thinking about replacement.  


Replacing a faulty window is less complicated, but more expensive and not eco-friendly. It is the easy way out, that is being chosen far too often. When you encounter any problems with your windows please contact a glazier or the window manufacturer and check whether there is anything that you can do to restore it. Of course, sometimes a replacement is inevitable for safety reasons. When you are making the decision on whether to replace or restore the windows in your house, take into account the following factors: budget, safety, and the environment.
