Clear and Simple Glass Replacement Service in Surrey
There is no need to replace the whole window if your double glazing is misted up or broken. Our simple and cost effective process means only the misted up or broken glass is replaced, leaving your window frame and home intact. We install replacement glass for double glazed windows and doors, including Upvc, aluminium and timber. Save time and money by replacing your double glazing glass, and enjoy a clear view through your windows once again.
Double Glazing Replacement Glass
Double glazing is created by sealing two panes of glass together, with an insulating barrier of air or gas like argon in between to help retain heat.
When the seal between the panes fails due to age or defects, moisture enters, causing condensation to form and the glass to mist up.
Failed double glazing not only looks unsightly but also significantly reduces your home’s energy efficiency.
Replacing double glazing glass is essential to restore both the appearance and performance of your windows. Get in touch with us today to discuss your requirements for double glazing replacement glass.
Toughened & Laminated Safety Glass
Toughened and laminated safety glass is used when safety and security is required, such as in doors, large windows and conservatory roofs.
Toughened glass is up to five times stronger than standard glass and shatters into non sharp crystal-like fragments if broken.
Laminated glass features a special plastic interlayer bonded between two layers of glass, which safely holds the fragments together when broken. Our glass replacement experts will advise you on the best type of safety glass to suit your needs.
Obscure & Privacy Glass
County Secure proudly supplies Pilkington textured glass to meet all your obscure and privacy glass needs.
Obscure textured glass is perfect for enhancing safety and privacy in areas such as doors, low-level glazing, and bathrooms.
Pilkington offers the widest range of obscurity levels and attractive options available. Contact us today to discuss your privacy glass requirements and find the perfect solution for your home.

When To Consider Double Glazing Glass Replacement
Recognising when to replace your double glazing glass is essential for maintaining energy efficiency, security, and comfort. Common signs include condensation between panes, visible cracks, and cold draughts—often indicating blown or failed units. Prompt glass replacement restores thermal performance, improves clarity, and helps protect your home from further damage.
Eco-Klear - Energy Efficient Glass Replacement
Double glazed units are now rated similarly to white goods for energy efficiency. Our Eco-Klear energy-efficient glass is A-rated, which is widely considered to be best practice by the Energy Saving Trust.
Eco-Klear double glazing features high-performance, low-iron SoftCoat glass with argon gas between the panes, offering significantly better energy efficiency than standard double glazing.
Eco-Klear reflects heat back into your home while reducing heat loss through the glass, helping to lower your energy bills.
Uni-Blinds - Stylish Integral blinds
Uni-Blinds, or integral blinds, are Venetian or pleated blinds that are permanently sealed within the cavity of a double glazed unit. Integral blinds offer unrivalled control of light and shade, making them ideal for Upvc windows, bifold doors and patio doors.

Frequently Asked Questions
Got questions about glass replacement? Whether you’re looking to replace blown double glazing or need advice on replacement glass for double glazed windows, we’re here to help. We specialise in cost-effective, expert window glass replacement—restoring clarity, insulation, and security to homes and businesses across Surrey.
Yes, we can handle misted window repair, but we don't repair the existing glass unit. Once a window has "broken down" and misted up, it's no longer airtight. The only way to fully repair the issue is to replace the defective glass unit.
Don’t worry, your window frame stays intact—we only replace the glass.
After replacement, your windows will look new, and the glass comes with a 5-year warranty.
Unfortunately, it's not possible to cut a hole in your existing glass door, as doors are made with toughened safety glass. If you need a cat flap in double glazing, we can easily arrange for a new glass unit with a pre-manufactured hole. Simply provide us with the make and model of your cat flap, and we'll ensure the correct size is cut for installation. Contact us to discuss your needs.
Double glazing fails because the weather and sun damage gradually break down the butyl seal, allowing moisture to enter the unit. While the desiccant inside the spacer bar absorbs moisture, once it's saturated, condensation forms, and the unit needs replacing. We specialise in double glazing glass replacement to restore your windows' efficiency and appearance.
