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 is Sterlingbuild?

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've sold to be installed in public buildings and homes all over the UK, Europe, United States and even Australia (unfortunately we weren't able to convince our boss to pay for a business trip to Sydney to see the installation).

 

More VELUX products in stock

We have many more VELUX products in stock than other retailers

 

We've grown rapidly since our start in 2008 and it's 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're 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.

Commmitment to our customers

We don't want to only offer the industry's leading products for your loft conversion or home extension. We want your shopping experience to be the best we can offer.

Best value for money

We are so committed to offering the best prices, we offer a Price Match+ promise. If you find one of our products for cheaper elsewhere in the UK, we won’t just match the price, we’ll beat it.

Best customer services

Our website is a Google Certified Shop. This means it meets the stringent regulations set by Google to provide reliable delivery and excellent customer services. Plus, customers can opt in to get free purchase protection provided by Google.

We have a team of experts on hand to answer your calls or emails. Each member goes through an intensive introduction to the products we sell and attend monthly training sessions of hands on demonstrations by our suppliers.
