Combine style and function with our sash windows

With our sash windows, you can enjoy slim sightlines and therefore make the most of outside views. Your sash windows will look equally stunning whether you are sitting inside, or appreciating the “kerbside appeal” of your property from the outside.

Emerald make it easy for you to reflect your personality in your windows. Opt for contemporary, bold or traditional finishes, including Cream, Chartwell Green, Greys and woodgrain finishes. These can all be seamlessly matched to the character of your home.

  • We worried about choosing a window company. We looked at all the usual national firms but we preferred the feel of a smaller local family run business as the rep was understanding of all our needs. The main issue for us was a quick turnaround and high quality frames with high security. We got this and more from Emerald.

    We are really impressed with the smooth finish. The fitters used dust sheets and cleaned up at every stage. We have already recommended them to our neighbours. Thank you for good value for money and a great finish.

  • The sales team at Emerald Windows are extremely knowledgeable. My house is a period property so the look was a very big player in which company I chose. I put my trust in Emerald and it paid off as the windows look fantastic and have brought even more character to the house. All the neighbours praised the work.

    The team of fitters worked to a high standard, they also cleaned up as they worked. The house inside and out was tidier when they had finished than before they arrived.

    I couldn’t give Emerald a higher recommendation.

  • My husband and I recently had all of our windows and doors replaced by the Emerald team. Right from the start it was a friendly service that all came with a good overall price when compared with other companies.

    We decided to have the grey coloured exterior and white interior windows. We are very pleased with the quality of the frames. They are so complimentary to our home.

    All the fitters were very friendly and professional and performed a high quality installation. The overall experience was a good one, we would highly recommend.

  • Very happy with our replacement double glazed windows. The installation was very efficient, and the fitters worked very well together and they removed all the old frames and rubbish from around the house. It has all been installed in a very effective manner. I would definitely use Emerald Windows again.

  • We had three windows fitted from Emerald Windows, I love the way we were treated by all the staff in all departments – we had a very friendly service throughout the process. We were very happy with the high quality windows that were installed into our home. Overall fantastic!
