Expert Sash Window Installation in Croydon & South London

Colin fitted 4 windows in my first floor flat with his assistant/colleague Jay. The work was completed over 3 days. It is an absolutely amazing result, the windows are beautifully fitted and look fabulous. I had 3 sash windows: one 3-window bay (living room), one in the kitchen, one on the bedroom. The bathroom window had a beautiful mayflower pattern. The difference in appearance, warmth and blocking of outside noise is remarkable. The guys were really hard-working, respectful and considerate and always hoovered and cleared up well. On the last day I felt totally at ease leaving them in my flat to finish (unusual for me) and came home to a wonderful transformation. If you need new windows, the expertise of Sanderstead Windows will change your life! Thank you so much. Roxana

Colin and John from Sanderstead Windows recently fitted new windows across my whole 2 bed house, a beautiful new front door, and stunning bifold doors across the back. They completely transformed my property front and back in only 4 days, working through one of the recent mini-heat waves.

I can’t fault their workmanship; professional, friendly, unbelievably clean and tidy at the end of each day. I felt more than comfortable leaving them alone in my house every day whilst I was out, and even locked up after themselves when I was home late.
Payment procedure clear and efficient.

Great work, great guys. Would highly recommend (and already have) to anyone needing new windows/doors.

Thanks guys. 👍🏻

Amazing experience from start to finish. Colin was incredibly quick to reply, and quoted a very reasonable price.

On installation day, it was 30 degrees, but Colin and the other window fitter worked tirelessly. They even made good of some pebbledash that needed to be chipped off. I’m so happy with the result, and love my new windows.

An all-round pleasure to work with – massively recommend!

Colin is one of a kind with such a fantastic work ethic! I couldn’t be more pleased with the results of my windows, he went above and beyond to ensure everything was perfect and that I was very happy with the work.

From the initial contact to the completion of the job, the entire process was smooth and professional. The windows are absolutely amazing and my expectations were exceeded and I honestly couldn’t recommend him enough.
Outstanding quality work, very satisfied and happy with his service provided.

The standard of work was amazing, he is conscientious worker.

Highly recommend and already passed on Colin’s details to family and friends.
