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

Placed advert Thursday. Contacted same day by Mike with a view to coming out and quoting next day. Came on time priced the job on Friday and arranged to start work on the Tuesday. Mike worked with his son Silas. What a really nice pair. Genuine, polite and got on with the job even though I asked for a few tweaks along the way. Both very old school and worked at their own pace - happy with work carried out and will use them again. Reasonable price too.

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.
