Can my original sash windows be restored instead of replaced?
In most cases, yes. Original timber sash windows were built to last and can often be restored even if they have rotten timber, broken sash cords, draughts or damaged glazing. Restoration preserves the character of your property while improving performance.
What is vacuum glazing?
Vacuum glazing is a modern insulating glass technology that uses an ultra-thin vacuum cavity between two panes of glass. It provides outstanding thermal insulation and excellent noise reduction while remaining slim enough for many traditional timber and steel windows.
Will vacuum glazing change the appearance of my windows?
No. Vacuum glazing has a very slim profile, allowing traditional windows to retain their original appearance while benefiting from significantly improved energy efficiency.
Do you offer heritage window repair?
Yes. We specialise in Heritage Window Repair and Window Conservation, restoring original timber and steel windows while respecting the architectural character of listed buildings, protected structures and period properties.
Can you repair rotten wooden windows?
Yes. We carry out professional Wooden Window Repair by removing damaged timber and replacing it with durable Accoya hardwood, extending the life of your original windows without the need for full replacement.
Do you replace broken sash cords?
Yes. Sash Cord Replacement is one of our core restoration services. We replace worn or broken cords, rebalance the sash weights and ensure your windows operate smoothly once again.
Can you stop my sash windows from being draughty?
Absolutely. Our Window Draft Proofing system seals gaps around the sashes while maintaining smooth operation, helping reduce heat loss, eliminate draughts and improve comfort throughout your home.
Do you restore steel windows?
Yes. We restore original steel windows by repairing corrosion, replacing damaged sections, preparing and repainting the frames, and installing modern glazing where appropriate.
Can you improve the energy efficiency of my existing windows?
Yes. We offer Window Upgrades including vacuum glazing, window draft proofing and professional restoration to improve insulation, reduce heat loss and increase comfort while preserving your existing windows.
Do you work throughout Ireland?
Yes. Cozyglaze provides nationwide coverage across Ireland, working with homeowners, businesses, architects and conservation professionals on projects ranging from single window repairs to complete property restorations.
Can you replicate windows that are beyond repair?
Yes. Where restoration is not practical, we offer a Window Replication service that accurately reproduces the original design, profiles and detailing while incorporating modern materials and improved thermal performance.
