Looking at reviews on CheckATrade is how I found Giles’ company. I can testify that their workmanship, communication, care and vision are high-quality. I was looking to have a French window installed; Giles helped with the structural engineer and building regulations as well as all the building works. Once on site, we realised the building needed joist replacements due to historic rot, along with securing an unsafe lift from a previous contractor, then adding ventilation, insulation and damp proofing. I’m so thankful to have met Giles and Aron. They removed the stress and made my home safe and smart!

10/10 for everything! I wasn’t looking forward to having the rising damp in my kitchen fixed, but Giles and Tom made it as pain-free and, more importantly, as mess-free as possible!! I shall definitely recommend Waterproof Systems to friends and neighbours.
