Have you ever noticed your double glazing starting to fog up between the panes? You’re not alone. Misting windows are a common problem for homeowners across the South Coast, including Bournemouth, Poole, and Dorset. Whether it’s a bedroom window, kitchen unit, or patio door, that cloudy appearance signals a problem that affects both your home’s comfort and energy efficiency.
If you’re searching for “misted double glazing repair near me” or “window repairs in Dorset,” you’re likely wondering why this happens—and more importantly, how to fix it. This guide from RPS Glazing Repairs explains why double-glazed units (DGUs) mist up and how professional repairs, including demisting, glass unit repairs, and UPVC window hinge repair near me, can save you from expensive replacements.
When you notice condensation between the panes of your double glazing, it’s usually due to a failed seal in the insulated glass unit (IGU) or double-glazed unit (DGU). These seals are designed to keep moisture out and gas in (usually argon or krypton for insulation).
When the seal fails, moisture penetrates the gap between the glass panes, leading to misting and fogging. This is not just unsightly—it also reduces thermal efficiency, causing higher energy bills.
💡 Did you know? According to the Glass and Glazing Federation (GGF), misted windows can reduce insulation by up to 30%, significantly impacting your home’s warmth and comfort.
Common Causes of Failed Double Glazing
Age of the windows – Older units naturally degrade over time.
Poor installation – Incorrect fitting, particularly not toe and heeling properly, leads to strain on the frames and seals.
Weather exposure – Coastal homes, especially around Poole and Bournemouth, are more vulnerable due to salt and wind.
Structural movement – A slight shift in the property can affect window frames.
Faulty hardware – Broken hinges, locks, or faulty drainage can allow water ingress.
How to Spot a Failed DGU
Key Signs to Look For:
Fog or mist between the panes (not on the inside or outside surfaces)
Water droplets trapped inside
Cloudy or milky appearance
Cold patches on the glass
Rising energy bills due to heat loss
