I can’t fault the work finished by Glenn (owner of smart-extensions) it’s the unfinished work that has now over run 15 months I have an issue with. We also had items stolen from the house whilst he was in charge, to the sum of £1200. Randomly (and in hindsight) t starting with meals missing from the fridge. A promise to help with the insurance excess has disappeared. After many promises to fix the unfinished work he eventually missed a set deadline and has stated he has no intention of finishing the work. Only gave one star as this is the minimum review available.
