Sean and his coworker Ian were superb. They kept us in the loop from order to finish. Very amiable and highly skilled window and door fitters. We are extremely pleased with the finished result. Would highly recommend.

Double glazing is available in a range of frame materials and glass specifications, and the best combination depends on your property, your priorities, and how exposed the windows are to weather and noise. uPVC frames remain a popular, practical choice thanks to their low maintenance needs, while aluminium windows suit homeowners who want slimmer frames and a more modern appearance. For period or character properties, timber windows can achieve the traditional look while still incorporating modern double-glazed units.
Beyond the frame, the glazing specification itself affects comfort day to day, including how much heat is retained, how much external noise is reduced, and how the unit performs against condensation. There is no single right answer for every property, which is why it helps to think about which rooms get the most use, which face the weather or busy roads, and whether existing frames are sound enough to simply have the glazed units replaced rather than the whole window. We install double glazing across Bristol, Burnham-on-Sea and Highbridge, working with homeowners to match the right option to each property.
Orientation and exposure also influence the right specification, since a window facing prevailing wind and rain needs robust weatherproofing at the frame joints, while a south-facing window might benefit more from glazing that helps manage solar gain. These factors are worth discussing room by room rather than applying one specification across an entire property regardless of position.
Noise-sensitive rooms such as bedrooms facing a busy road often benefit from particular attention to the glazing specification, since the right combination of glass thickness and gap width can make a noticeable difference to how quiet a room feels, even where the frame material stays the same.



A misty or cloudy appearance between the panes of glass is one of the clearest signs that a sealed unit has failed and moisture has found its way in. This is a glazing issue rather than a frame issue, and the unit itself typically needs replacing rather than the whole window. Other signs to watch for include draughts around the edges of the frame, windows that are difficult to open or close smoothly, and visible gaps or cracks in the sealant where the frame meets the wall.
If the frame has started to warp, discolour unevenly, or feel soft to the touch in places, this points towards a problem with the frame itself rather than the glazing, and may need frame repair work or replacement. Locking and handle issues are also worth addressing promptly, since a window that doesn't close and lock securely compromises both comfort and security. Catching these problems early generally makes them easier and less disruptive to put right.
It's also worth considering how existing trickle vents and ventilation are handled when windows are replaced, since airtight new glazing without adequate ventilation can sometimes shift condensation problems from between the panes to the surface of the glass inside the room. Getting this balance right is part of a properly considered double glazing installation rather than an afterthought.
Security hardware fitted within double glazed units is worth reviewing at the same time as the glazing itself, since older locking mechanisms can be less robust than current options, and upgrading them alongside new glazing is often more practical than doing it as a separate job later.
Moisture trapped between the panes can indicate a failed sealed unit. Where the surrounding frame remains suitable, replacing the glass unit may be possible without replacing the whole window. An assessment checks the frame and required glass specification before ordering.
Double glazing means two panes of glass held apart by a spacer bar and sealed around the edge to form one unit. The gap between the panes slows the movement of heat, so rooms stay warmer and outside noise is reduced compared with a single pane. The sealed unit sits inside a frame, and the frame material, opening style and glass you choose all shape how the finished window looks and performs.
As local window fitters based in Weston-super-Mare, we replace old or failing windows with new double glazed frames measured for each opening. Most homeowners choose between three materials: practical, low-maintenance uPVC windows; slim, strong aluminium windows; and traditional timber windows for character homes. For period properties with vertical sliders, our sash windows page explains the options. Each window replacement starts with a survey, then the old frame is removed, the new one fitted and sealed, and the reveals made good.
If condensation appears between the panes, the unit's seal has usually failed. Where the frame is still sound, replacement glass units can be fitted without changing the whole window. Our guide to misted double glazing helps you decide whether to repair or replace, and the double glazing repairs page lists every window and door repair we carry out.

It is a window unit made from two panes of glass separated by a sealed gap, which reduces heat loss and outside noise compared with single glazing.
uPVC is practical and low maintenance, aluminium offers slim sightlines and timber suits traditional homes. We can talk through the options at your survey.

On the day of installation, our team works room by room so your home isn't left fully exposed at any point, removing the old window, preparing the opening, and fitting and sealing the new unit before moving on to the next. Dust sheets and floor protection are used throughout, and old frames and glass are removed from site as the job progresses. The exact sequence depends on how many windows are involved and the layout of the property, but the aim throughout is to keep disruption to a minimum.
Once new double glazing is fitted, simple routine care keeps it performing well. Wipe down frames with a soft cloth and mild soapy water rather than abrasive cleaners, keep drainage channels clear of debris so water can escape properly, and operate handles and locks regularly so they don't seize up from lack of use. If you notice condensation forming on the inside of the glass rather than between the panes, this is usually a ventilation issue in the room rather than a fault with the window itself. We've been installing windows across the South West since 1998, and that experience shapes the practical advice we give every customer about keeping their glazing in good order.
Keeping an eye on hinges and friction stays is also worthwhile, since these parts allow a window to open and close smoothly, and like any moving mechanism they can wear or loosen with regular use over the years. A brief check during general cleaning helps you notice any change in how a window operates before it becomes a more noticeable problem.
Double glazing uses two panes of glass with a gap between them, while triple glazing adds a third pane for additional insulation. Triple glazing can offer further thermal and acoustic benefits, though it is heavier and not always necessary depending on the property.
If the frame is in good structural condition and only the sealed unit has failed, replacing just the glazed unit is often possible and avoids disturbing the surrounding frame or wall finish.
Double glazing does reduce external noise compared with single glazing, and the level of reduction depends on the glass thickness, the gap between panes, and how well the frame is sealed and fitted.
Draughts are often caused by worn seals around the opening sash, a frame that has dropped slightly, or gaps in the perimeter sealant rather than a problem with the glazing itself, and these are usually straightforward to address.
This varies considerably depending on the quality of the original installation, the frame material, and the conditions the windows are exposed to, so it's best assessed on a case-by-case basis rather than assumed from a fixed figure.
