Short answer
Check if your windows show signs of rot, draughts, or difficulty opening; these indicate replacement may be necessary. In England, confirm compliance with building regulations using FENSA certification or local authority approval before proceeding. Always enquire about included compliance checks and services when selecting a contractor to ensure a hassle-free experience.
Acting promptly on signs of window wear can prevent further damage and energy loss.
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
- Persistent condensation between double glazing panes indicates seal failure allowing moisture intrusion.
- Visible wood rot or warping in window frames suggests structural deterioration requiring attention.
- Constant draughts around windows signal gaps due to ill-fitting frames or failed seals.
- Windows refusing to open or close smoothly suggest misaligned sashes possibly from settlement.
- Noticeable cold spots around windows hint at poor insulation from outdated or damaged glazing.
- Peeling paint or finish deterioration on frames points to moisture retention and potential rot development.
- Increased external noise infiltration suggests thinning glass or failing seals compromising acoustic insulation.
Common causes
- Wood rot often results from prolonged moisture exposure degrading the structural integrity of frames.
- Failed double glazing seals allow moisture to enter, leading to clouded or misty appearance of glass.
- Settlement in the home can misalign window frames causing operational issues and air leakage.
- End-of-life frames, worn through age and exposure, lose their ability to insulate and function correctly.
- Deteriorated weatherstripping loses elasticity over time, leading to draughts and energy inefficiency.
What you can do yourself
- 01Request a detailed breakdown of what services the quote covers to avoid unexpected costs later.
- 02Verify that old frames are responsibly disposed of or recycled to align with environmental practices.
- 03Ensure that all installations meet local building regulations to avoid complications or fines.
What the glazier does
- Replacing frames and glazing resolves draughts and improves insulation when frames are beyond repair.
- Repairing existing frames is suitable if rot is minimal and the glass remains unaffected, preserving character.
- Upgrading to energy-efficient double or triple glazing enhances insulation, reducing energy costs and noise.
- Installing new window seals is effective when only minor air leaks exist, enhancing thermal retention.
- Consider adding secondary glazing to existing windows to improve insulation without frame replacement.
How the job usually runs
- 01Conduct a detailed survey to assess the condition of frames and glazing, ensuring suitability for replacement.
- 02Remove old frames carefully to prevent damage to surrounding structure, preparing for new installation.
- 03Fit new windows ensuring alignment and secure fixing, then check for smooth operation post-installation.
- 04Seal gaps around the frames using high-quality materials, confirming improved insulation and airtightness.
- 05Make good on plaster and sills, restoring any disturbed areas around windows to their original finish.
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:
- Frame material choice affects cost due to durability and maintenance; timber often costs more than uPVC.
- Window style impacts pricing as bespoke designs like bays or sashes require more complex installation.
- Energy efficiency ratings influence price since higher-rated glazing offers better insulation benefits.
- Complexity of installation affects labour costs, especially in older houses with non-standard openings.
- Compliance with building regulations can add to costs due to the need for certification and inspections.

Questions
What should I do if I notice condensation between my double glazing?
Condensation between double glazing panes indicates seal failure. It's advisable to contact a professional glazier to assess whether the seals can be repaired or if full unit replacement is necessary. Prompt action prevents further moisture damage and maintains window efficiency.
How can I tell if my window replacement is urgent?
Urgency depends on symptoms like persistent draughts, rot, or inability to open and close windows. These issues suggest structural problems or significant energy loss, requiring timely replacement to prevent further damage and ensure comfort and security.
Are building regulations important for window replacement?
Yes, building regulations ensure windows meet safety and insulation standards. In England, compliance often requires FENSA certification or local authority checks. Verify compliance to avoid legal issues and ensure your new windows perform effectively and safely.
What should a window replacement quote cover?
A comprehensive quote should include materials, labour, waste disposal, and compliance with building regulations. It should also cover potential restoration work around the window area. Ensure hidden costs are disclosed and clarify what services are included to avoid surprises.
