Double Glazing Units in Bristol
Supply and installation of sealed units across Bristol and the South West.
Specialist Double Glazing for Bristol Properties
Bristol's position at the mouth of the Avon Gorge gives the city a distinctive maritime climate – prevailing south-westerly winds are funnelled through the gorge, exposing properties in Clifton, Hotwells, and along the harbourside to stronger draughts and greater heat loss than sheltered inland areas. Well-specified glazing is not a luxury here; it is essential for comfort and energy efficiency.
The Georgian crescents and townhouses of Clifton and Hotwells – many built from local Bath stone and oolitic limestone – are among Bristol's most architecturally sensitive properties. A significant number sit within conservation areas where Bristol City Council requires replacement glazing to be sympathetically designed. We manufacture slimline sealed units with krypton gas fill and heritage-profile spacer bars that replicate the slim sightlines of original single glazing, satisfying conservation officer requirements while delivering modern thermal performance to Building Regulations Part L standards.
Across Redland, Bishopston, St Andrews, and Montpelier, Victorian and Edwardian terraces dominate. These properties typically feature original timber sash windows or early uPVC replacements from the 1990s, many now showing signs of seal failure – misting between panes, draughts, and poor thermal performance. Replacing failed sealed units within existing frames is the most cost-effective upgrade, and it is the service we carry out most frequently across these inner north Bristol neighbourhoods. Our measuring guide helps you get accurate dimensions for any window type.
In Henleaze, Westbury-on-Trym, and Stoke Bishop, 1930s semi-detached houses with generous bay windows benefit enormously from upgraded Low-E glass with argon gas fill, reducing heat loss through glazing by up to 50% compared to original single-pane units. Meanwhile, the modern harbourside apartments along the Floating Harbour and in developments at Wapping Wharf and Finzels Reach typically require standard sealed unit replacements in aluminium or composite frames – straightforward work that we complete efficiently at competitive prices.
All units are manufactured to BS EN 1279 standards and BFRC energy rated,.

What Our Bristol Customers Say
"Our Georgian townhouse in Clifton had original single-glazed sash windows that let in terrible draughts – the wind off the Gorge made the front rooms almost unusable in winter. Double Glazing Units manufactured slimline sealed units that fitted perfectly within the existing timber sashes without altering the external appearance. The conservation officer had no objections, and the difference in warmth and noise reduction has been remarkable. Our heating bills dropped noticeably that first winter."

Frequently Asked Questions – Bristol
Yes. Bristol has numerous conservation areas – Clifton, Hotwells, Redland, Cotham, and parts of the city centre among them. Bristol City Council requires that replacement glazing in these areas is sympathetically designed to preserve the character of listed and period buildings. We manufacture slimline sealed units with krypton gas fill and heritage-profile spacer bars that replicate the appearance of original single glazing, making them suitable for conservation officer approval. We can advise on specifications for your specific conservation area.
Standard sealed units for Bristol properties start from around £35. Georgian sash replacement units – common across Clifton, Hotwells, and the city centre – typically range from £55–£120 per unit depending on size and glass specification. Victorian bay window units for terraces in Redland, Bishopston, and Totterdown fall within a similar range. Visit our cost guide for a full breakdown of Bristol pricing.

Absolutely. Properties in Clifton, Hotwells, and Leigh Woods that overlook or sit near the Avon Gorge are exposed to stronger prevailing winds channelled through the gorge. This increases draughts and heat loss through windows significantly. Upgrading to argon-filled Low-E sealed units can reduce heat loss through glazing by up to 50%, and the improved seal dramatically cuts draughts. Acoustic glass options are also popular in these areas to reduce wind noise.
