We have a complex period home with significant heritage requirements, so we were understandably picky about who would create our new front door. This company was a joy to work with. They completely ‘get’ old properties and were really helpful when it came to compliance with historic building regulations. The finished result is superb; who would have thought we could achieve some insulation as well!

We couldn’t decide for ages between new sash windows or secondary glazing. These guys were so patient with us and went through the different benefits and drawbacks several times with no pressure to make a decision. Ultimately, we opted for secondary glazing and are so pleased with the results. There is significantly less noise and much more heat, plus the units don’t mask our original sash windows or spoil the aesthetics. The service was excellent, too – five stars all round!

The installers have just finished, and you honestly wouldn’t know they have been here – they even hoovered! We needed old secondary glazing removed and new units fitted. Everything was done in a timely and professional manner, with great care taken not to impact the existing sash windows or any of the internal décor. We would have no hesitation in using this company again, but it looks from the workmanship and performance as if we won’t need to see them for many years to come.

Sliding Sash Window FAQ’s

How long does installation take on average?
That all depends on how many windows you have fitted and whether there are any challenging or unusual features. A professional team that has done a thorough survey will be able to estimate how long installation will take.
Our installation is due when it’s freezing outside. How can we minimise the impact inside the house?
A professional installation team will work room by room and keep internal doors closed so only one room at a time has a lower temperature, but that won’t last for very long. The process of taking the old window out and putting the new one in is relatively swift, it’s all the finishing that takes the time.
Do we need to move and cover the furniture before our sash window installation?
t’s always helpful for installers if they have as much free access to the windows and the surrounding area as possible. Taking down curtains and moving furniture and ornaments out of the way saves time on the day. Check with your installers if they are happy to move furniture and add covers if you aren’t able to. The best ones even hoover up before they leave!
