What can I do to an old conservatory?

Revamping a glazed extension space can make a massive difference to your home, especially if you are not using it as often as you would like to. Older conservatories may not be able to regulate the temperature correctly, whereas in the winter it’s excessively cold, and in the warmer months just far too hot! However, rather than completely re-building your conservatory, there are features that can be upgraded to give you that brand-new feeling.

Tiled conservatory roof replacement

A tiled roof won't just enhance the look of your conservatory but, along with replacing your windows with double glazing, will make your space energy efficient and comfortable to use. You will no longer be stepping into a freezer or a sauna, but a cosy and inviting room that can be used all year round.

A tiled roof conservatory can give the appearance of a full extension and with a range of colours available, pick from; Moss Green, Plum, Ash Gray & more. For more information, browse through our brochure.

Lantern roofs

If you are unsure about blocking the sunlight from your conservatory, we have a solution! Modern lantern roofs allow more light into your conservatory but will ensure your conservatory is just as energy efficient. They can achieve U-values as low as 1.0!

To finish off your new lantern roof, you have your choice of two durable exterior coated finishes, classic Crisp White or Anthracite Grey, and the option of 3 designs. For more information, take a look at our brochure.

Do I need planning permission for a conservatory?

You will be glad to hear that the simple answer to this question is no. Conservatories generally fall within your permitted development rights; a government scheme that permits homeowners to extend, as long as they follow the set requirements. Unfortunately, there are some types of properties in Exeter and Devon where permitted development rights cannot be used. If you have; a flat, maisonette, listed building, or live in one of the 51 conservation areas in Devon, you may need planning permission or be restricted by Article 4 Directions.

"Brilliant local company. Installed a new door for my father (after a recommendation by a friend). Great product, great price, but (& I can not stress this enough) their kindness & care dealing with an elderly gent, especially regarding the guarantee (so both myself as his son & he could have a copy) was amazing. I genuinely did not believe service like this existed any more. Lovely people to do business with & a company I can thoroughly recommend."

"Cannot fault customer service in anyway from this firm we called in reference to get a quote to replace some windows. Nick came out the same day was very helpful with ideas and suggestions of what types of windows that would suit and with 24 hrs a quotation was waiting in my inbox. We shall be almost certainly be putting an order in shortly. Cannot recommend this company more highly to anyone thinking of new windows or doors should definitely give Nick a call."

"Through a recommendation, I popped into the office to see if they could help me source a new door handle. Nick was extremely helpful and ordered one for me through a company they use. I will certainly recommend the company to family and friends and I will use them for replacement windows and doors in the future. Many thanks for the free tin of silicone spray!"
