Frequently Asked Questions

How long does double glazing installation take?

Most installations are completed within a day, causing minimal disruption to your home. Our expert team works efficiently to transform your windows room by room, so you can start enjoying a warmer home right away. Ready to book your installation?

Will double glazing really reduce my energy bills?

Yes! Our customers typically see a significant drop in their heating costs. Quality double glazing creates an effective insulation barrier, keeping warm air in during winter and hot air out during summer. The savings on your energy bills often help offset the installation cost over time.

How long will my new double glazing last?

Our double glazing is built to last decades with proper care. We’re so confident in our quality that every installation comes with our 10-year guarantee. Plus, if you ever need repairs or maintenance, our local team is always here to help.

I'm interested but not sure if now is the right time?

If you’re feeling the cold or watching your energy bills rise, then now is the perfect time. We’re currently seeing record demand for double glazing as more homeowners look to cut their bills and increase home comfort. Our installation slots fill up quickly, especially during colder months, but we can usually book you in within a few weeks. Plus, every day you wait is another day of paying higher heating bills – why not get your free quote now and see how much you could save?

Do I need planning permission for new double glazing?

Most standard double glazing installations don’t require planning permission. However, if you live in a conservation area or listed building, we’ll guide you through any necessary approvals. We handle all the details, making the process hassle-free. Why not book a consultation to discuss your specific requirements?
