Jamie has always given an honest and reliable service that is delivered to a high standard.Posted on Google Deborah Alexander-DawsonTrustindex verifies that the original source of the review is Google. Jamie was incredibly helpful in advising what we could do with the space we had, advising on materials and best outcomes. Listened to issues that needed resolving with excessive rain water and then got on with the job. He did exactly what we asked, checked when things needed alteration (tree roots) and was amazing with communication. Start to finish - great job and we are very happy with our new driveway.Posted on Google Graham ReederTrustindex verifies that the original source of the review is Google.

Brilliant job done by Jamie, thoroughly happy and exactly as we asked! Would recommend!
I would highly recommend using this service. Punctual, reliable and professional, demonstrating excellent understanding and skill in undertaking the works efficiently and under fair pricing. Got the job done will minimal fuss and overcame a couple of unforeseen environmental issues with the site professionally and with good insight. Highly recommended.
jamie arrive when he said he would. His machinery was excellent. He listened to my very ameture instructions and turned them into a professional job. I would highly recommend him and I intend to use him again next time i need this sort of work.
Can’t recommend Jamie enough, when Jamie first popped over to quote I thought it maybe a week or more but he was quick to get the pricing across and explained all work involved. He’s worked, long and hard during some cold winter days.
The work carried out has been neat, and always left the site clean and tidy. Will be coming back in the coming months to carry out more work. Over all in cannot rate his work enough.
Thanks again Mr Legg!
