Why Sliding Sash Windows Suit Period and Modern Homes
The vertical sliding sash is one of Britain’s most enduring window designs, originating in the Georgian era and remaining a defining feature of Victorian and Edwardian homes across the country. Far from being purely decorative, the double-hung mechanism allows you to open the top sash, the bottom sash, or both simultaneously – giving you precise control over ventilation without sacrificing the classic look.
Modern uPVC versions replicate every detail of the original timber design, from run-through sash horns to traditional hardware finishes, but without the rot, warping, or repainting that timber demands. Whether your property is a period terrace or a contemporary new build, a sliding sash window adds instant kerb appeal and character.

Just had 7 Windows, 2 doors and our fascias done by Malbern, was a bit nervous but have to say was delighted from start to finish, the lady who came round initially was lovely and there was no pressure whatsoever, she told us to ring her when we had made our minds up, we managed to get a bit of a discount and went with it...Next The guy came round to do the survey, very meticulous and gave some great advice. Then, we were contacted about dates, and then the fascia guys came and did a superb job. The following week, Carl and Mark did the windows over 3 days, lovely friendly guys, did a superb job and kept the place clean and tidy, by the time the job was done you wouldn't know they had been there, apart from the fantastic windows and doors, 100% happy, new grey windows and all the neighbours are loving them as well, recommend Malbern from our experience.

I couldn’t fault Malbern, they have been brilliant from start to finish. There was no pressure when it came to selling, and Phil helped us bring our vision to life well within our budget. Darren, our fitter, was absolutely brilliant. His attention to detail was brilliant and he was so tidy. We had 11 windows and one door fitted in just 3 days! I couldn’t fault them, highly recommend!

We had 2 windows fitted and a composite front door in vintage Green. All the work was completed in a day. No mess at all. The workmen took all our old windows and door materials away with them. Such polite and professional tradesmen who complete the job to a high standard. We would recommend this company.
