One of the most common questions we get is whether it's worth repairing existing windows or replacing them entirely. The answer depends on the condition of your frames, the age of the glazing, and what problem you're trying to solve.
If your frames are structurally sound — no rot, warping, or significant damage — then replacing just the sealed glass unit is almost always the better option. It's faster, less disruptive, and typically costs a fraction of full window replacement. Your existing frames, handles, and hinges all stay in place.
Full replacement makes more sense when frames are damaged, draughty, or no longer meet Building Regulations. It's also the right choice if you want to change the style, size, or opening mechanism of your windows.
