Misted Double Glazing Repair in Exeter

Montrose Glass provides misted double glazing repair in Exeter and is available 24 hours a day, 7 days a week, 365 days a year. Exeter is a cathedral city in Devon with a compact historic centre, a large student population, and a housing stock that ranges from Georgian terraces in St Leonards and Victorian semis in Heavitree through to newer build estates on the city’s expanding eastern and northern fringes.

Misted double glazing is one of the most common glazing problems reported by Exeter homeowners, particularly in older properties where the original sealed units have reached the end of their service life. When a failed seal allows moisture to enter the space between the panes, you will notice condensation between panes, a foggy or milky appearance, or streaking that cannot be wiped away from either surface. This is the defining sign of a blown unit, and it will not clear on its own. Whether you have noticed foggy windows in a Victorian terrace in St Thomas or trapped moisture in a newer double glazed unit on one of Exeter’s modern estates, the fix is the same: the affected sealed unit needs to be replaced. Our glaziers carry glass stock in their vans and can cut and fit a replacement insulated glass unit on site in many cases, avoiding the need for a return visit.

What Does Misted Double Glazing Repair Involve in Exeter?

Misted window repair in Exeter begins with understanding why the problem occurs. Every double glazed unit is made up of two panes of glass separated by a spacer bar and hermetically sealed around the edge. That seal keeps an inert gas, typically argon, trapped between the panes and gives the unit its insulating performance. Over time, exposure to temperature change, UV light, and general wear causes the seal to degrade. Once the seal fails, moisture from the surrounding air enters the gap between the panes. You see the result as condensation between panes, foggy patches, or a persistent milky haze that confirms the unit is blown. No amount of cleaning will resolve it because the moisture is inside the unit, not on the glass surface.

The repair process for foggy double glazing repair in Exeter does not require removing your window frames. A Montrose Glass glazier removes the beading that holds the glass in place, takes out the failed sealed unit, and fits a new insulated glass unit of the correct specification into the existing frame. Because our vans are stocked with glass that can be cut to size on site, misted glass unit replacement in Exeter can often be completed in a single visit. This approach preserves your existing frames, whether they are uPVC, timber, or aluminium, and keeps disruption to a minimum. For properties in Exeter’s conservation areas, such as parts of the city centre close to the cathedral, retaining original frames is often a practical and planning-sensitive priority, and our repair-not-replace approach suits this directly.

Why Should You Not Leave Misted Windows Unaddressed in Exeter?

Blown double glazing repair in Exeter matters beyond appearance. A sealed unit that has failed is no longer performing its insulating function. The argon or air fill between the panes is what provides thermal resistance, and once that seal is compromised the unit becomes little more than two single panes of glass with a damp gap between them. The practical result is heat loss through the window, which increases your heating bills and reduces the comfort of the room, particularly through Exeter’s cooler autumn and winter months.

Condensation in double glazing in Exeter also causes long-term damage to the unit itself. Trapped moisture leads to mineral deposits and permanent staining on the inner glass surfaces, which become increasingly difficult to see through and cannot be cleaned away. In some cases, persistent moisture inside the unit can also affect the surrounding frame or reveal if left unattended for a prolonged period. It is worth noting that misting is caused by a failed seal in the double glazed unit rather than a fault with the frame, which means that in the vast majority of cases you do not need to replace the whole window. Replacing only the affected sealed unit is quicker, less disruptive, and more cost-effective than a full window replacement. Our Window Repair and Replacement service covers situations where frame damage is also a factor, but for most cases of misting the unit alone is all that needs attention.

We used Montrose Glass for a construction project in London recently. They were fantastic. Service was great, as was the workmanship. The 2 glaziers are a credit to the company. Also, they turned up and carried out the works during heavy snowfall without complaint. We would definitely recommend them.

I needed to get some work done for quite a while on my house, but kept putting it off - after a couple of calls to Montrose Glass I felt comfortable discussing it and they made it so easy and simple that I\'ve decided to get it all sorted. Great service and I have already got them quoting my mums house and will have no worries referring them on in the future.

Yes. Misting is caused by a failed seal in the glass unit itself, not the frame, so in most cases Montrose Glass replaces only the affected sealed unit and retains your existing frame. This approach is quicker and more cost-effective than a full window replacement, and a glazier will confirm this on site in Exeter at no call-out charge.

Condensation inside double glazing is caused by a failed edge seal on the insulated glass unit, which allows moisture from the surrounding air to enter the gap between the panes. Once trapped moisture is present inside the unit, the fogging or milky appearance will not clear on its own and the unit needs to be replaced. This is a sealed unit fault rather than a frame problem, and it is a straightforward repair for a qualified glazier.
