Here’s what others say about us!

My husband and I  have employed Tim Mavay and his landscaping team for over eleven years. He has been completely responsible for planting, gardening, plant selection and maintenance over this time and his work has always been impeccable.  He has attended to our 1000 square metre gardens each month with dedication, interest, care and initiative. His approach to our property and our needs has been professional and helpful at all times and he has always had a great team working with him.

He has always been proactive in his suggestions to improving our property. We trust him and he has become our friend.  Stephen and I have no hesitation in recommending him, his employees and his business.

“Oxygen Horticultural Services have been maintaining our garden for over 3 years. Our beautiful garden is a testament to Tim and his team’s hard work.  They happily mow, blow, prune, trim, clear gutters, plant, water, fertilise — just to name a few of the many tasks they handle.  Tim always has great advice on anything to do with the garden, landscape or gardening — his knowledge is quite extensive.

I am happy to recommend Tim and the team at Oxygen Horticultural Services. They have been providing regular garden maintenance, plants and advice to us for the past three years and our garden continues to thrive. The team is always punctual,  professional, flexible and efficient. They have no problem dealing with our heavy leaf litter including spiky bunya leaves and specific requests such as ensuring our new pup does not escape  or disposing of extra garbage. Tim has identified and treated many pests on our plants over the years and provided good plants and advice whilst working happily with our landscape architect.

Oxygen Horticultural Services has been keeping my gardens looking wonderful for 8 years now. I put this down to Tim’s vast knowledge of plants, his scheduling of maintenance to keep things looking their best, of course his care of the garden and his respect for my property when he and his team are on site. It’s always easy to discuss ideas with Tim, in fact it’s a pleasure because of his friendly nature. Several neighbours now use Tim too.

Tim Mavay at Oxygen Horticultural has been our landscape gardener for approximately four years coming each fortnight. In that time he has always been extremely reliable and ensures the garden looks lovely. I love that Tim doesn’t require direction but seems to  innately know what is required and completes this with no hassle. Having said that when bigger jobs need doing we have always discussed costs and implementation prior to commencement of the work. Tim and his team are very devoted to their work. I have a separate lawn mowing man and on one occasion very last minute was unable to mow the lawn and I had a function that night at the house. I rang Tim and he came down from Avalon on a Friday afternoon and mowed the lawn even when it wasn’t part of his scope of works at my house. Very much appreciated!

Tim and his crew have lovingly nurtured my garden from a wasteland to tropical oasis over the past eight years, saving me much back breaking work.  Apart from coming every month, rain or shine, he has been a reliable source of information about what to plant, where and why. During this time he has installed an irrigation system and laid a path as well as creating a ferny grotto. His horticultural knowledge is extensive as is his ability to offer ideas for new garden projects whilst respecting my own plans and my budget!  He is thoughtful, creative and thoroughly dependable. I would encourage anyone to entrust their garden’s care to him and his crew.  My garden has thrived under his care.

I first met Tim Mavay of Oxygen Horticultural Services in November 2009 when he had been recommended to me as a gardener who could help tidy up a large overgrown garden in a new holiday rental property my husband and I had purchased on Sydney’s Northern Beaches in July 2009. He made an excellent job of this over a couple of visits and I subsequently decided to have Tim help us manage the garden on a regular fortnightly basis from January 2010 and which he continues to do. It very quickly became clear that Tim was much more than a maintenance gardener and was able to put forward sound suggestions of things we could consider to enhance the features of our property if we wished. He is also a very pleasant and courteous person to work with and always makes time to communicate with us.

We have been so pleased with Tim’s work that wherever we can we also have him help us out at our permanent home and again this has ranged from general maintenance work through to a reasonably large back garden makeover in recent times.

I am delighted to provide this reference for Tim and would highly recommend his horticultural/garden services for both garden maintenance and garden landscaping projects.

I have had the pleasure to work with Tim from Oxygen Horticultural services for ten years. In these years I have had three homes with different gardens that have required varied work, two being very large. Tim has a wonderful sensibility for nature and a keen eye besides being very knowledgeable and experienced about plants, and bugs which on the northern beaches is most important!  Tim has a very relaxed approach to his work and no problem is too big or cannot be solved. Tim has very professional people working for him as well and they all seem to enjoy their work.  I have no hesitation in recommending Tim and his team!

I would like to take this opportunity to thank you and your team for your professionalism and diligent maintenance over the last 3 years.

It is difficult to find tradespeople that are consistent, on time and that communicate with their clients, while delivering a great result.

Landscaping is the final and most important step when presenting a property, accordingly I will not hesitate to continue recommending your company for my clients.
A recent sale we made in Narrabeen set a suburb record.

This garden apartment needed urgent attention which you accomplished despite being given only a few days’ notice.
Once again, we thank you for the detailed works you have provided for myself and my network of clients.

We wish you every success in the future.
