Really good experience with Cosyhomes. I especially want to thank Rachel who went out of her way to arrange a suitable time for our window gearbox replacement. Thank you!

We have had a new glass door, window panes, and a window bracket fixed. We are thrilled with Cosy Homes. It is a family run business and Rachel and Phil offer the best customer service. It is a company you can trust, which is so refreshing. They know their product and were able to advise us on the best door design and window panes. They respond to any communication promptly, and are friendly, a pleasure to deal with. We highly recommend. We are very happy!

Frequently asked questions

How long does double glazing last?

On average, double glazing lasts between 20 to 35 years, depending on the quality of materials and installation. At Cosyhomes, we use high-quality energy-efficient windows built to go the distance, and all our installations are backed by a 10-year insurance-protected guarantee.

Can I just replace the glass instead of the whole window?

Yes, if your frame is still in good shape, we can replace misted or broken double glazed units without replacing the whole window. It’s a cost-effective fix, especially if you’re dealing with condensation between the panes. Wondering how to fix misted double glazing? Get in touch and we’ll assess your options.

What is stippolyte glass?

Stippolyte glass is a type of textured privacy glass, often used in bathrooms or entrance doors. It allows plenty of light in while obscuring the view from outside, ideal for both privacy and style.

How do I know if I need planning permission for a porch?

Most porches in the UK don’t need planning permission if they meet size and location limits. But if you’re wondering do you need planning permission for a porch on your home, we’ll check and advise during your quote visit.

What’s the difference between a conservatory and an orangery?

Both add space and light, but orangeries have more solid structure, with brick pillars and a flat roof often featuring a roof lantern. Conservatories are usually fully glazed. Need help choosing? We’ll walk you through the pros and cons.

How long does an installation take?

Most window or door installations are completed within a day.

How to get scratches out of a glass window?

Minor scratches on glass can sometimes be polished out with a non-abrasive cleaner or specialist glass polish. For deeper marks, replacement may be the safer option. Not sure? We’ll let you know the best course of action when we inspect.
