If your windows are foggy, steamed up or permanently misted between the panes, you’re probably dealing with a blown double glazed unit. At Jcarter Locksmiths, we provide fast, affordable blown window replacement across Dorset, restoring clarity and insulation to your home without replacing the entire frame.
A “blown” window (also known as misted or foggy double glazing) happens when the airtight seal between the two panes of a double-glazed unit fails. This allows moisture to seep in between the glass, causing condensation, cloudiness, and often a dirty appearance that can’t be wiped off.
Signs you may have a blown window include:
Cloudy or milky appearance between the glass
Water droplets or streaks inside the unit
Reduced visibility or light
Cold patches near the window
Window feels less energy-efficient
We don’t need to replace the entire window — just the glass unit itself. Our services include:
Diagnosing misted or blown units
Measuring and supplying matching sealed units
Swapping out blown glass for new, insulated units
Ensuring a clean, tidy finish with minimal disruption
All replacement units are made-to-measure and fitted to match your existing window frames, whether they’re uPVC, aluminium, or timber.
Restores clear views and natural light
Improves thermal efficiency
Reduces condensation and damp
Boosts property value and kerb appeal
Much cheaper than full window replacement
Costs vary depending on the size and type of glass. Most standard replacements are very affordable – and much cheaper than replacing the whole window.
No — once the seal is broken, the only long-term solution is replacing the sealed glass unit.
We aim to measure up quickly and order made-to-measure units, which are usually fitted within 3–7 days.
Not at all – we just replace the blown glass unit. Your existing frames remain untouched.
