"GLS carried out the refurbishment of St Mary's Church in Perivale, which is a Grade I listed building. Despite there being a major delay due to problems with English heritage, when the work finally got under way, Dimitar was on top of everything, ready to go. Being a structural architect, it's important to have someone I can trust on the job - he is efficient and effective and we get on well. Although GLS wasn't the cheapest, I take that as a good sign - his quotes are competitive and the quality speaks for itself. I'm already speaking to him about future much bigger projects. I'd highly recommend GLS Building Contractors."
