Short answer
Check for misting between glass panes first, as this often indicates a failed seal that might be repairable without full replacement. If frames are rotten, a complete replacement will likely be necessary. Prompt attention can prevent further energy loss and possible frame deterioration.
Prompt attention to double glazing issues averts increased energy bills and prolongs window lifespan.
Replacement windows and external doors in England usually need building-regulation compliance (FENSA or the local authority). Ask what is included.

How to recognise it
- Misting between the glass panes indicates that the moisture barrier has failed and allowed condensation inside.
- Cold glass surfaces during winter might mean that the argon gas insulating layer has been compromised.
- Draughts near the bead suggest that seals have degraded or are improperly fitted, allowing air ingress.
- Difficulty opening windows could be due to warping from moisture damage or frame misalignment.
- Noticeable noise from outside means that the insulating layer is no longer effective, possibly due to damaged seals.
Common causes
- Failed seal allows moisture to enter between panes, causing mist and reduced insulation.
- Degraded spacer decreases structural integrity, leading to glass movement and potential seal failure.
- Rotten beading lets moisture in, weakening the frame and impacting the window's stability.
- Frame damage from wear and tear leads to improper sealing and draughts or water ingress.
- Insufficient sealing during installation allows air and moisture to breach the unit's integrity.
What you can do yourself
- 01Check for misting only in the glass if the frame is sound, as this might involve just seal replacement.
- 02Improve ventilation to address condensation on inside surfaces by allowing moist air to escape outside effectively.
- 03Regularly clean and maintain seals to prevent dirt accumulation which can compromise the seal's effectiveness.
- 04Inspect for visible damage to frames regularly, protecting against larger issues like draughts or water ingress.
What the glazier does
- Reglaze the unit to resolve misting between panes when the existing frame remains intact and functional.
- Replace the entire window if both the glass and frame are compromised, restoring full efficiency and function.
- Apply new sealant to address minor draughts and moisture intrusion where existing seals have degraded over time.
- Replace spacers when they have degraded, restoring the window's integrity and preventing further seal failures.
- Install a draught excluder to address minor air ingress issues when the main frame is otherwise sound.
How the job usually runs
- 01Measure the existing window to ensure accurate fitting of new glass or frames, confirming specifications match.
- 02Order suitable units or frames based on measurements to ensure proper fit and finish upon installation.
- 03Remove the old glazing carefully to avoid damage to the surrounding frame, ensuring no debris is left.
- 04Fit the new glass or window, checking alignment and seal integrity to ensure no draughts or moisture can enter.
- 05Seal and finish the installation, inspecting all seals for continuity and confirming none are missing or improperly applied.
What the price depends on
FirstGlass Windows does not publish a fixed price. That is agreed with the firm you appoint. Differences usually come from:
- Material quality affects price; high-performance glass and robust frames cost more but offer better insulation.
- Labour complexity influences cost; more complex installations or repairs require skilled labour and longer hours.
- Window size impacts pricing; larger windows require more materials and possibly more labour to handle safely.
- Access difficulty increases cost, as hard-to-reach areas may need scaffolding or special access equipment.
- Installation type, such as full replacement versus repair, changes the cost due to differing material and labour needs.

Questions
What should I do if I notice misting between panes?
If misting occurs between panes, it likely indicates a failed seal. Examine if the frame remains intact. If so, repairing or replacing the double-glazing unit may suffice without needing to replace the entire window. Prompt action can maintain energy efficiency and prevent further issues, like frame damage. Consult a specialist to assess and address the problem effectively to prevent escalating costs.
How can I assess the severity of my window issues?
Check for misting, draughts, and difficulty opening windows. Misting often suggests seal failure, while draughts indicate seal degradation or frame damage. Difficulty opening may mean warping or misalignment. Each symptom requires different attention: minor seal issues might only need new sealant, but significant frame damage often necessitates full replacement. Consulting a professional can provide a comprehensive assessment and tailored solutions.
Is double glazing repair or replacement subject to regulations?
Yes, replacement windows and external doors typically need building-regulation compliance in England. Check if your installer provides certification, such as FENSA, or inform the local authority yourself. Ensuring compliance keeps your property safe and up to code, avoiding possible fines or complications during future property sales. Always verify what’s included in the installation service regarding regulations and certification.
What should a quote for double glazing services include?
A comprehensive quote should cover the cost of materials, including glass and frames, labour charges, and any additional expenses such as scaffolding or special access requirements. It should also specify the work details, like repair versus full replacement, and include compliance with building regulations, such as FENSA certification. The timeline for completion and any potential contingencies should also be part of the quote.
