Glass Changes & Replacement
Glass Replacement & Misted Unit Repairs
Misted, cracked, or broken glass doesn't always mean a new window. Our glass replacement service restores clarity, insulation, and security — typically at a fraction of the cost of a full window replacement.
Why Choose Us
What Sets Our Service Apart
Condensation between the panes is the most common sign of a failed sealed unit. It means the seal has broken and moisture has entered the cavity. We remove the failed unit and replace it with a brand-new, A-rated sealed unit — leaving your existing frames untouched. It's one of the most cost-effective home improvements you can make, restoring the thermal performance and appearance of your windows for a fraction of the cost of full replacement.
Fraction of the Cost
Replacing the glass unit alone costs significantly less than replacing the entire window frame — saving you hundreds per window, potentially thousands across a whole house.
Quick Turnaround
Once measured, most replacement sealed units are manufactured and fitted within 5–7 working days. No long waits, no disruption to your daily life.
A-Rated Sealed Units
All replacement glass is supplied as energy-efficient, argon-filled sealed units with warm-edge spacer bars for maximum thermal performance.
All Glass Types
We replace standard double glazing, toughened safety glass, obscure/patterned glass, decorative leaded units, and laminated security glass.
No Frame Damage
Our glaziers remove and replace the sealed unit without disturbing or damaging your existing window frames, trims, or internal decoration.
Improved Clarity
Failed sealed units look cloudy, hazy, or permanently fogged. A new sealed unit restores crystal-clear vision and makes your home look cared for again.
Better Insulation
A failed sealed unit has effectively become single glazing with no insulating gas layer. Replacing it restores full double-glazing insulation performance immediately.
Our Process
How It Works — From Enquiry to Completion
Identify the Problem
Misted glass, cracked panes, broken safety glass — tell us what's wrong and we'll arrange a convenient time to visit and assess.
Measure & Quote
We take precise measurements of each glass unit and give you a clear, itemised quote on the spot. No obligation, no hard sell.
Manufacture
Your replacement sealed units are manufactured to exact dimensions. Standard units take 5–7 working days; specialist glass may take a little longer.
Swift Fitting
Our glazier removes the failed unit, fits the new one, and cleans up — typically in 30–60 minutes per window. Your frames are left completely untouched.
Understanding Failed Sealed Units
Every modern double-glazed window contains a sealed unit — two panes of glass separated by a spacer bar and sealed around the perimeter to trap an insulating layer of air or argon gas between them. Over time (typically 15–25 years), the perimeter seal can fail due to thermal expansion and contraction, UV degradation, or poor-quality original sealant. Once the seal breaks, moist air enters the cavity and condenses on the inner glass surfaces, creating the cloudy, misty appearance that many homeowners recognise. This moisture cannot be cleaned out because it's between the two panes, not on the surface. The only solution is to replace the sealed unit — a straightforward job that preserves your existing frames and restores full insulation and clarity.
Types of Glass We Supply and Fit
We carry and supply the full range of residential glass types. Standard float glass is used in most windows and is available in clear or tinted finishes. Toughened safety glass is required by building regulations in locations such as doors, side panels, low-level glazing, and windows near baths or showers — it's five times stronger than standard glass and shatters safely into small granular pieces. Laminated glass consists of two panes bonded with a PVB interlayer and is used for enhanced security and acoustic performance. Obscure glass provides privacy and is available in various patterns and opacity levels. Decorative leaded glass uses lead strips and sometimes coloured glass to create traditional or contemporary patterns — we can replicate existing designs or create something new.
Why Glass Replacement Is a Smart Investment
Many homeowners assume that misted or damaged glass means they need entirely new windows. In the vast majority of cases, that's simply not true. If your frames are in good condition — and most uPVC and aluminium frames last 25–30 years — then replacing just the glass unit is the smartest option. It costs a fraction of the price, takes a fraction of the time, and delivers identical insulation and clarity. You avoid the disruption and expense of removing and refitting frames, redecorating around new openings, and disposing of perfectly serviceable window frames. For homeowners on a budget or those who simply want to maintain their existing windows rather than replace everything at once, glass replacement offers outstanding value and results.
