Core Sash Windows offer a professional, yet relaxed and friendly service. All our surveyors and sales representatives have years of experience in the double glazing industry and many of them have worked as fitters of double glazed sash windows and doors in the past so have real, hands-on experience with the product.
They've designed our sash windows from scratch and gone on to successfully market those same sash windows throughout all the boroughs of London. We have over a 10 year history in the window industry and in this time have installed casements, doors and sash windows in London and providing a first class fitting service, including in conservation areas and listed buildings.
We choose not to work with UPVC sash windows and focus fully on our timber sash windows range in order to ensure that our workforce and our surveyors are totally in tune with our product, our service and our ethos.

Sash windows have always been an extremely popular part of the London home. From the Georgian and Victorian eras up until today, they remain an essential design feature and are often a mandated replacement due to the presence of conservation areas and listed buildings. It's also the preference of many homeowners to replace their windows with timber sash windows given the aesthetic appeal of the product.
Casement windows are the most popular choice of window in the United Kingdom and around Europe. Essentially a casement is any window that operates on hinges. The window is hinged at the top right side of the vertically hung sash, so that it opens outward or inward along its entire length in same way as a door.
New windows can instantly improve the appearance of a room, house or extension but what is the uniqueness of an aluminium window? Aluminium windows are resistant, modern and can be a long term investment for your home, so it's no surprise that they're one of the most popular types of windows installed in the UK.
Shutters can really add a touch of elegance to your home and can be made to look great almost anywhere, particularly with sash windows or timber casement windows In addition, with such a wide range of options / colours available, there's something for everyone. Shutters are a great addition to your home and some styles have been popular for hundreds of years.

I’ve used Core Sash a few times, on an old home and now our next project/home. We keep going back because their work is top notch. They’re friendly, ensure you have all the information you need up front, are courteous on the job, and leave the place spotless daily. The after care is also speedy and helpful, super useful when obtaining information to pass on to new owners.

I can't recommend the Core Sash Windows guys enough. From start to finish the service was excellent, the level of craft and finish exemplary and the installation team were polite, professional and worked in an extremely clean and tidy way. I wish I'd known about them when I was having the sash windows at the front of my house replaced a couple of years ago.

The guys from Core Sash were punctual and worked very cleanly paying attention to avoid dust in the room by using a divider. The finished double glazed windows are excellent! I even asked to change a few bits before finishing and that was carried out without any problem. Extremely happy of the result and will go back with them in the future. As it happens with good suppliers the wait time is a little long, but it's a testament to their good work!

Fantastic job by Core at our house London E12. We had all the windows at the front of our house replaced as well as the shutters. We are incredibly happy. There was such a high degree of professionalism from the first email requesting a quote to the final shutter fitting.
Each member of the core team has their own specialisms from the fitters to the joiners and decorators. The team work really well together and are so clean and tidy. Big shout out to Boris, Emmanuel and Ossie. The dream team who worked on our project in Wanstead.

Core Sash windows carried out work on a rental property of mine. Even though I had spent over £10k the service was bad. They installed the windows without making any attempt at giving the windows a professional finish. Holes were left where they had screwed the bolts in on the exterior of the windows which would have allowed sitting water when it rained. Beading was left hanging off. Then on the interior, they left holes which needed wood filler and painting to be carried out. I lost money due to tenants not been able to move into the property as they would have created dust by sanding down the
