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.

Hi, we recently had Florin and his team do some work on my Mum’s garden. He has done an incredible job and we are so pleased with his work. He was very friendly, polite and completed the job in a timely manner and to our requirements and very reasonable and good ideas and suggestions. I would have no problem recommending him and his team again and will do in the future if I know of anyone needing. Thank you for your hard work

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.
