Double Glazing Units in Liverpool
Supply and installation of sealed units across Liverpool and Merseyside.
Specialist Double Glazing for Liverpool Properties
Liverpool's position on the Mersey estuary exposes its housing stock to a maritime climate that inland cities simply don't face. Salt-laden air carried off the Irish Sea accelerates seal degradation and frame corrosion, while persistent westerly winds drive rain into even the smallest gap around a glazing bead. That means sealed units across Liverpool tend to fail earlier than the national average – and when they do, the misting, draughts, and heat loss are compounded by the city's higher humidity levels.
In the Georgian Quarter around Canning Street, Huskisson Street, and Falkner Square, many properties sit within conservation areas where planning restrictions prevent changes to the external appearance of windows. We manufacture slimline sealed units specifically for these situations, fitting discreetly within original timber sash frames to deliver a meaningful thermal upgrade without triggering a planning application. Our units meet the heritage glazing standards that Liverpool City Council's conservation officers require.
The Victorian terraces stretching across L8, L15, and L17 – Toxteth, Wavertree, and Aigburth – represent Liverpool's largest single housing type. These properties typically have timber or early uPVC frames with standard openings that suit a 4-16-4 argon-filled unit with a Low-E coating – the specification that delivers the best balance of thermal performance, condensation resistance, and value. We replace hundreds of failed units in these terraces every year, working within existing frames to keep costs down.
In Woolton, Allerton, and Childwall, the 1930s semi-detached houses with large bay windows and generous rear openings benefit enormously from upgraded Low-E glass with argon gas fill. Many still have their original single glazing or early double-glazed units from the 1990s that no longer meet Building Regulations Part L. Replacing these with modern sealed units can cut heat loss through the glazing by up to 50%.
The modern developments along the Waterfront, Baltic Triangle, and Ropewalks present different challenges altogether – large floor-to-ceiling panes, curtain walling systems, and aluminium-framed units that require bespoke manufacturing to non-standard dimensions. We produce units up to 3000mm – 2000mm to accommodate these larger openings, all built to BS EN 1279 standards and BFRC energy rated.

What Our Liverpool Customers Say
"We have a Victorian terrace in Aigburth and every window had misted up – the old sealed units were well past their best and the damp air off the Mersey wasn't helping. Double Glazing Units replaced all fourteen units with argon-filled Low-E glass within the existing timber frames. The difference has been remarkable – no more condensation, noticeably warmer rooms, and our energy bills dropped by around £30 a month that first winter. The fitters were careful with our original frames and left everything spotless. Can't recommend them highly enough."
– Sarah & David K., Aigburth, L17
Frequently Asked Questions – Liverpool
The Georgian Quarter around Canning Street and Falkner Square falls within a conservation area, so maintaining the historic character of the windows is essential. We manufacture slimline vacuum or slim-profile sealed units designed to fit within original timber sash frames without altering the external appearance. A 4-6-4 slim unit with a Low-E coating provides a significant thermal upgrade while satisfying conservation officer requirements. We can also match period glazing bar profiles for multi-pane sashes.
Yes. Liverpool's proximity to the Irish Sea means properties are exposed to higher levels of wind-driven rain, salt-laden air, and humidity compared to inland cities. Salt deposits can accelerate corrosion of frame hardware and degrade perimeter seals over time. We use marine-grade sealants and recommend enhanced weatherproofing specifications for coastal and waterfront properties. Argon-filled Low-E units also help combat the condensation that is common in Liverpool homes during the damper months.
Standard sealed units are typically manufactured and delivered to Liverpool addresses within 5–7 working days. Bespoke sizes, specialist glass types such as acoustic or self-cleaning, and non-standard configurations may take 10–14 working days. We deliver to all Liverpool postcodes and across Merseyside including the Wirral, St Helens, Southport, and Knowsley.
Absolutely. Victorian terraces are one of the most common property types we work with across Liverpool – particularly in Toxteth, Aigburth, Wavertree, and Tuebrook. These houses typically have timber or early uPVC frames with standard openings that accept a 4-16-4 argon-filled Low-E sealed unit. We replace failed, misted, or single-glazed units within the existing frames, avoiding the cost and disruption of full window replacement. Use our measuring guide to get accurate dimensions.
