Double Glazing In Gloucestershire

Double glazing works by trapping a layer of inert gas, usually argon, between two panes of glass inside a sealed unit. This creates a thermal barrier that reduces heat loss, improves window insulation, and cuts down on noise from outside. A-rated windows take this further by incorporating low-emissivity glass coatings that reflect heat back into your home, making them the most energy-efficient option available. Whether your property is a Victorian terrace in Cheltenham or a newer build on the outskirts of Gloucester, the right double glazed unit can make a measurable difference to your energy bills and comfort.

One of the most common problems our double glazing installers in Gloucestershire are called out to address is a failed seal. When the hermetic seal around a double glazed unit breaks down, moisture enters the cavity and causes condensation between the panes. This presents as a persistent mist or streaking that cannot be wiped away, and it means the unit has lost its insulating properties entirely. This is a different issue from a structural frame problem, where the uPVC frames or timber surround may be warped, cracked, or allowing draughts through regardless of the glass condition. Our glaziers assess both the sealed unit and the frame on every visit and advise on the most cost-effective route forward. In many cases, only the sealed unit needs replacing, and you can find out more about that service on our Misted Double Glazing Replacement page. Our vans are stocked with glass that can be cut and fitted on site, so double glazing replacement in Gloucestershire often takes place the same day you call.
