Posted 2 days ago
Very good experience
Very good experience. Came quickly to assess the job, priced it up that day and fitted us in a few days later as there was some urgency. Turned up on time, polite and did a good job with no mess. Will use again when needed.Verified reviewerJob location: N1410 Tree Felling

Excellent
I would have no problem recommending Denny’s Tree Surgery. I have used them 3 times now. He is very professional, on time, and polite. He respects the importance of good relations with the neighbours, tidying up fully after the work. He organised the paperwork with the council. Jessica in the office dealt with all our queries straight away. All in all an excellent job and a pleasure to work with Thank you.Verified reviewerJob location: N410 Tree Surgeon

Highly professional job, friendly service.
Mark and his team did a brilliant job reducing the height and spread of two large horse chestnuts at the end of our garden. The trees are now much smaller and neater but still an attractive shape. Prior to the work Mark also advised on the best time of year to cut these particular trees and the correct approach to maintain their health. As he has worked on other trees in our garden in the past we know his advice is sound. After the work was done they thoroughly cleared up the garden and the pavement in the front of the house as well. Overall I would highly recommend Mark.Verified reviewerJob location: EN5

My name is Mark Denny and I have been working as a qualified tree surgeon since 2013. Over the years I have developed extensive arboricultural knowledge and experience and have a great passion for tree care. At Denny’s Tree Surgery we offer a whole range of tree care services from tree felling, tree pruning, pollarding and stump grinding. We can also give you advice on your trees health and how to best maintain and care for your tree. We cover all areas in and around North London.
If your tree is located within a conservation area, or is covered by a Tree Preservation Order (TPO), we offer a service where we will take care of all applications and communications with your local council on your behalf.
We pride ourselves on turning up when we say we are going to, completing the job that was agreed and leaving your garden tidier than when we found it! Take a look at our reviews to hear what our clients have to say about us.
