What is a casement window?

A casement window is traditionally one with a hinged sash that opens out like a door. However there are other options for your casement windows and you can choose to instead opt for side hung, top hung or even bottom hung. If you’re feeling unsure at which style to choose then our friendly team have more than 10 years of experience fitting windows in Surrey, Berkshire and Hampshire and will be able to give you all the information you need to make an informed choice about which style is right for you.

Our uPVC casement windows are available in a range of colours and finishes. If you are looking for something to enhance your traditional character property then our wood effect finishes could be ideal, choose from rosewood, mahogany, Irish oak or golden oak. For a more contemporary look, white, slate grey, dark grey or black could be a stylish choice. Or add some quaint English style to your home with our popular cream or chartwell shades.

We had an additional window fitted following 10 fitted last year. Once again the planning and prep from the office team was great and the installation was carried out to a high standard and all done with very little mess.

Three Counties replaced my home's exterior doors. Their quotes were reasonable, as were their pre-sale staff who were pleasant and helpful, not pushy. The job was completed within a month of the order by Ryan, who was entirely professional and careful to work with the fixtures and fittings of the doorways. Three counties will be the first company I call whenever I'm looking for windows, doors or conservatories in the future

We are incredibly pleased with our door from Three Counties. It's good quality and has really helped to modernise the look of our house that we are currently renovating. The staff were a pleasure to deal with and very quick to get our door ordered and installed. Would highly recommend!

Trying to find a company to replace all our windows and doors was a minefield. A lot of the classic hard sell techniques and the "buy now for a once in a lifetime price" annoying sales tactics. But from the outset Three Counties were so different. They listened to what we wanted, gave advice were relevant and made suggestions where we could reduce the overall cost without sacrificing the end product. The installation was a breeze. The fitters were tidy, efficient and the end product was faultless. Quite literally. I couldn't find a single fault or issue. It speaks volumes when I have mentioned to other people we have had the windows done and as soon as I mention by who, the response is the same. Oh, I know them, great company. Would highly recommend them
