About Us

If this is your first time shopping for roof windows or rooflights, you may not have heard of us. So here's an introduction to Sterlingbuild, the products we sell and the team behind the UK's largest independent online roof window retailer.

Who Are We?

Sterlingbuild is an online home improvement shop specialising in windows for loft conversions and home extensions. We stock a wide range of well-known brands, including VELUX, Sunsquare and RoofLITE at fantastic low prices, which we have sold to be installed in public buildings and homes all over the UK, Europe, United States and even Australia (unfortunately we were not able to convince our boss to pay for a business trip to Sydney to help install it).

More VELUX products in stockWe have many more VELUX products in stock than other retailers

We have grown rapidly since our start in 2008 and it is all thanks to our customers - both home owners wanting to convert their loft or add more daylight to dull rooms and businesses wanting to provide the best products at the lowest prices for their customers. In June 2014, we moved to larger premises in Folkestone to keep up with demand and hire new staff to ensure we provide the best customer service we can.

We are able to keep thousands of products in stock for faster delivery. Our huge warehouse stocks VELUX, ECO+, Lightway, FAKRO, Sunsquare and RoofLITE products - to name a few.

Our Core Values

One afternoon, the whole team got together (less the 3 company directors) to decide on our company's core values. We wanted to encompass every aspect of the company - ensuring the best for our customers and for each member of the team. These are the 5 core values we all aim to every day:

  • Keep our customers informed every step of the way
  • Always be the best we can 
  • Value and recognise our team’s contribution
  • Teamwork across the business
  • Ambition for personal and company growth

We put these values into our long-term strategy as well as our day to day activities.
