Slimline Double Glazed Sash Window Upgrades in Bristol
Upgrade the Sashes, Keep the Original Frames
If your sash windows need better comfort but the original box frames are still in suitable condition, replacing the moving sashes may be an option. Bristol Sash Window Services assesses the existing frames before discussing made-to-measure replacement sashes with slimline double glazing.
This approach can retain the original box frames and the character of the window. We carry out sash window upgrades in Bristol, Clevedon and North Somerset.
Could you Replace the Sashes and Keep the Frames?
A sash window has moving sections, known as sashes, set within the fixed box frame. If the box frame is sound, it may be possible to replace the sashes without replacing the complete window.
We inspect the existing frames first to check their condition and suitability. If they need repair, we can discuss that before recommending an upgrade. For wider timber or window repairs, see our sash window repair service.
Made-to-Measure Replacement Sashes
Replacement sashes are made to fit the existing openings. Details such as profiles, glazing bars, horns and mouldings can be considered so the new sashes sit appropriately with the original window and the style of the property.
The existing weights and balance are also considered during fitting, so the upgraded sashes can operate properly within the retained frames.
Slimline Double Glazing in Period Windows
Slimline double glazed units can provide an option for homeowners who want to improve the glazing while retaining the traditional sash window appearance. The suitability depends on the window, the existing frame and the requirements of the property.
If draughts are a concern, discreet draught proofing may also be considered. Read more about our sash window draught proofing service.
Listed Buildings and Conservation Areas
Changes to windows in listed buildings may require consent. Requirements depend on the property and the proposed work, so check with the local planning authority before proceeding. Our listed building sash window page has more information.
When Full Window Replacement May be Needed
If the existing box frames are not suitable to retain, a sash upgrade may not be the right option. We can discuss the condition of the windows and whether repair, refurbishment or a new double glazed sash window is more appropriate.
See our page about new double glazed sash windows for full replacement options.
