Got David's number from this site after checking out the recommendations. Our building needed some urgent work on inadequate and leaky guttering after recent heavy rain and David was quick to come out and quote and straight forward in his advice. The team were able to do the job swiftly and efficiently - with no scaffolding which we'd worried might be needed to due to height and angle and were happy to provide pictures if I couldn't inspect (I could in the end). Hasn't been tested heavy rain wise yet but confident we're good to go and happy to recommend based on the service to date.
