Delta Roofline Services did a large job for my pensioner mother on her roof, subsequent builders showed us that they had done a terrible job, leaving the roof in a state where we are now seeing repeated issues. James acknowledged the poor quality of work in email exchange when I showed him photo/video evidence, then proceeded to ignore my emails. I filed a small money claim with the local court after time, he ignored that too, the court has now ruled a CCJ in our favour for costs which James is also ignoring. Avoid at all costs.
