Stephen

Archie was fantastic. He deserves the five stars given. Not only did he come in at the budget provided, but communicated several times and promptly on text and email. He arrived on time and even though we had supplied him with what a keylock company had said we needed - it was wrong - he went out and got the correct locks that were needed for the job and never charged extra or anything. He sent us an invoice after the job and we paid him. Simple. What a joy to get 5 star service in the current climate.

Quick work and reasonable price. Lovely chap. I'm very pleased with the work done.

The job was to cut back a severely overgrown patch of garden. Chris & his team, Adrian & Cosmin, gave me a competitive quote, after coming to visit the site to assess what needed to be done. They started next day and completed the job quickly and to my complete satisfaction. The site was cleaned up & all waste taken away. I will definitely use them again and strongly recommend them.
