Figuring out whether to repair or replace a damaged window can be tough. Many people think they need a whole new window when a simple repair would do, wasting time and money. On the flip side, some underestimate the problem and repair a window that really needs replacing, only to face more issues later. Taking the time to asses the situation carefully can help you make the right choice. With our many years of experience as commercial glaziers in Devon, we can help you understand if your window reeds repairing or replacing. We're going to cover some common issues and discuss the most appropriate action to take in that situation.
Damp or Mould
Damp and mould often occur from water seeping through windows or moisture trapped between the panes of double glazing. Leaving this issue unattended can lead to the accumulation of water, which can result in mould or rot, making repairs or replacements more costly. Minor damp issues may be resolved by simply resealing your windows, however a significant amount of rot or mould would usually require a replacement.
Cracks and Damages
Any damage to your windows, whether it's the frame or glass, requires immediate attention. While replacing a windowpane is fairly straightforward, damage to parts like the frame, casing, or lintels can lead to bigger issues down the line. Replacing them now can help you avoid more significant problems later.
Faulty Windows That are Difficult to Use
You often don't need to replace the entire window, simply replacing the affected part is usually effective and more budget-friendly. Whether it's a faulty crank or lock, these components can often be easily swapped out by yourself or a professional. While new homes may need adjustments as they settle, older homes might require a full replacement due to wear, heat and cold causing misalignment or warping. Some issues can be fixed with a quick readjustment or reseal, but wood rot or swelling may require complete replacement.
Misted/Foggy Window
A misted or foggy window, also known as a "blown" window is indicated by condensation between the window panes. These issues require a professional to repair them. If you notice water leakage near the window, check if it's from the window itself, poor guttering or damaged casings may be the cause. However, if water comes through the window, it likely means the seal has deteriorated, necessitating a full replacement. If left unaddressed, these issues can lead to heat loss and compromised security.
Poor Heat Control
If your windows are letting in excessive heat or sunlight, it may be time to replace them with energy-efficient double glazed windows. These windows improve heat resistance and reduce glare while blocking harmful UV rays. Many older homes feature single-pane windows, which can make insulation difficult. Upgrading to double glazing is a smart investment, especially in extreme climates as it enhances comfort year-round.
This guide will assist you in deciding whether to repair or replace your windows based on the issues you’re facing. While the idea of a full replacement might be tempting, it’s often not needed; a straightforward repair can be just as effective and more cost-efficient. Consider replacement only if your windows are affecting your comfort or requiring constant maintenance that leads to higher long-term expenses.
