Landscaping- 22 May 2026
Right from our 1st meeting I knew Iain was the right person for the job. He explained what he was going to do and how long it would take. Rain did delay the job for a week but Iain was in constant contact keeping me updated. Iain is your old fashioned typical trades person, turns up at the crack of dawn raring to go and just gets on with it. Im delighted with the work Iain has done, I would hire Iain again without hesitation and srongly recommend him to people I know. Thanks Iain

Extensions- 19 Sep 2018
Negative! Would not recommend using this person. He is totally unreliable, does not deliver and impossible most of the time to contact. Introduces charges that are not agreed and does not keep to any schedule. Failed to complete the job and has left us with significant issues. Wish we had seen the other recent negative feedback from other very dissatisfied customers.
