About Us

If you own a Georgian or Victorian property, when you hear “sash windows” you’ll probably think of the ‘standard’ designs: one pane above one pane, two panes above two panes, and so on and so forth. However, the large variety of sash windows in London means that most companies will have to be able to produce bespoke sash windows in order to be able to keep up with demand.

At Core Sash Windows, we can manufacture almost any type of sash window, like-for-like, so you can be confident that we’ll be able to perfectly replicate your original windows, no matter how intricate. The only difference our customers ever notice is the high thermal performance of our low-emissivity double-glazing!

We also understand that trying to replicate a very specific type of window can be a stressful experience for a customer. Small details, which might be considered ‘insignificant’ by some companies, may be vitally important to you, and due to the vagueness of their Quotations, with most companies you can’t be sure exactly what you’ll be getting…until it’s too late. To help put your mind at rest, we’re able to provide you with technical documents from our factory (upon request), and we won’t pressure you for a deposit until you’re satisfied that you’ll be getting the bespoke sash windows that you want. We’re also a FENSA registered company, which means that you won’t need to get anyone from the council over to certify the work, saving you time and money.

With us, you can rest assured that you’ll be taken care of every step of the way – from the initial survey, to the planning stages, to the installation. Speaking of installation…with our fully comprehensive fitting service, you’ll also get our traditional pointing joints and hand painted-finish, so we can even replicate every aspect of your original finishing. We can also provide less comprehensive fitting services if required; just let us know what you’d prefer and we’ll make it happen!
