Highly recommend Sanderstead Windows! I needed a window handle changed and, rather than charging me for a call-out, they gave me honest advice on how to fix it myself. Their tip worked perfectly and saved me a lot of money. It’s rare to find such an honest, helpful local business. I’ll definitely be using them for any future work.

NATURAL LIGHTING SOLUTIONSWhy Choose Our Roof Lanterns?
A roof lantern is a glazed structure installed on flat roofs to maximise natural light entering your living space below. Unlike traditional roof windows or flat rooflights, roof lanterns extend upwards creating a stunning focal point whilst dramatically increasing natural daylight. Our premium aluminium roof lanterns combine sleek design with exceptional thermal efficiency, perfect for modern and traditional homes across Croydon and South London.
Maximise Natural Light in Your Home
Our roof lantern installations dramatically increase the amount of natural light entering your living space, creating an impressive sense of openness and space, regardless of the sun’s position. The sleek design acts as a stunning focal point whilst providing amazing views of the sky above, perfect for stargazing!
Studies show that homes with roof lights can increase natural lighting by up to 300% compared to traditional windows, significantly improving wellbeing and reducing electricity costs through decreased reliance on artificial lighting.

I was looking for someone local who could supply and install Flush casement windows. After meeting with a few suppliers and checking reviews, I chose to go with Sanderstead Windows. Colin recommended Residence 7 windows, which really look the part. In total Colin installed 9 Windows and a back door, spread over around a year as we worked through a big renovation. I’m really happy with how the job went, the Windows look fantastic, and Colin was flexible and easy to deal with. Highly recommended.

Colin and Aca done a fantastic job. said they was going to be here at 07:30am and they was bang on time, also said the windows was going to be fully fitter within one day, they done by folding doors with blinds in and out all within one day. Very impressed with the workmanship even in the rain, the doors turned out far better than we thought. No decorating needed inside, perfect fit. Fantastic job top marks to the guys. Highly recommended .
