10 Replacement of flat roofing on front porch extension
Posted 14 April
James was recommended to us to replace the flat roof on our porch extension and over our bay window. From his initial visit to provide us with an estimate to his completion of the work - on schedule and on budget - James was really easy to deal with. He provided wise advice at the planning stage, and gave clear answers to any questions we had throughout the process. James did a thorough and professional job and we are very happy with the results. At the end of the process, all rubbish was carefully disposed of. James and his 2 workers were unfailingly polite and helpful. Highly recommended.Verified reviewerJob location: RH1010 Repair to roof where loft conversion was starting to leak.

James and team were excellent, he identified the problem and shared pictures to help us understand and agree course of action. Additional optional work was requested by us (securing loose ridge tiles) because scaffolding when up made it good sense to do so. He also capped our chimneys. Very happy customer!Verified reviewerJob location: RH1910 Water coming through cloakroom ceiling.

Job location: RH19Contacted James Knott regarding water coming through the cloakroom ceiling . He came within 30mins.and on checking the flat roof above he advised that the recent freak weather had caused excess debris to be washed down from the main roof causing the down pipe to become blocked and resulting in the excess water to collect. It was resolved in a very quick time and no damage was done.10 Roof repair

James responded on the same day to my call and visited to assess the damage that day.Despite rain preventing work starting he kept me in touch with likely dates for the work to start and did the job as soon as possible . He was reliable ,efficient and courteous as was his assistant. I wouldn’t hesitate to use his services again.Verified reviewerJob location: RH1910 wall taken down

The quality of the work was good. James arranged scaffolding. Both scaffolders and James worked to limitations of when they could access the job to avoid disturbing my neighbor. James took time to explain the job before and during. The job took the length of time he said it would and scaffold was not left lingering afterwards. The price was as quoted plus a few pounds for unexpected lead flashing. I would use James again.Verified reviewerJob location: RH17
