Martin was quick to make contact with me and arrange a time to quote. He came to my house with his wife and they were able to give me really good advice and a quote on the spot which was appreciated. I didn't use Martin on this occasion more due to my own timings then anything else but would certainly look to contact him in the future for any other jobs required.

Tried to talk me into getting the work done then putting in the drop kerb at a later date (pointless as I still wouldnt have any legal access to the drive!) not that I had any confidence in him returning to do the 2nd part anyway. Would not hire this company.
