Areas we cover
Based in South Croydon, building across South London and the Surrey and Kent borders.

Our South London patch
We’re based in South Croydon, which puts us roughly in the middle of the area we work in. Most of our jobs are within half an hour of the yard, which matters more than you’d think: it means we can get to site early, pop back when building control are due, and sort out any problem quickly.
If your home is just outside the postcodes below, ring anyway. For the right project we’ll travel further, and we’ve built in Surrey and further into Kent for repeat customers, including our Windmill, Surrey new build.
Builders in Croydon
Croydon is home ground. We’ve built extensions in Shirley, refurbished houses in South Norwood, converted lofts in Thornton Heath and built new houses in CR0. See our builders in Croydon page.
Builders in Bromley
We do a lot of work across the London Borough of Bromley, from Beckenham and West Wickham to Chislehurst and Orpington. See our builders in Bromley page.

Google review “We were quite certain we wanted to proceed with Smiley Building Services as soon as we received the quote. We can honestly say that we are so glad we did - our new garage conversion benefits everybody and is a great place to escape to after a hard day!”
Tod, SW16 · Customer testimonial “I thought Smiley Building Services had a really good, helpful website. Once Smiley had visited my home and explained the options that were open to me, I felt happy with what was discussed and decided to go ahead. My garage is now converted to an excellent standard.”
Gramian, BR4 · Customer testimonial “We decided to have the loft converted and as the property was being rented out to tenants we were on a tight budget. Smiley Building Services not only delivered a high standard of work, they also completed the project well within our budget. My partner and I are delighted with the service we received from Smiley.”
Mr & Mrs Sucara, SE9 · Customer testimonial
