Your legal duty of care

Damage involving wood decay and loss of wood strength may require immediate action to avoid potentially dangerous situations.  The owner of a tree has a legal duty of care for others should a decayed tree or part of it damage or injure a third party.  See the article from Aviva “Loss Prevention Standards for Hazardous Trees

From St Peter’s Churchyard, Marlborough:

I would gladly recommend Conservation-Contractors Ltd to any organisation seeking to have a wide variety of trees managed and worked on both efficiently and to the very highest standards.

from Church Warden , on behalf of the PCC, St James’ Church, Ludgershall and Faberstown
“The lads excelled, William, and we were pleased that the operations went without a hitch, or damage to any grave stones beneath the horse chestnut tree. Goodness only knows how the falling timber was guided so expertly, but it really was a joy to witness. It wasn't just the skills level that impressed, but the work ethic and bonhomie which secured excellent relationships all round. Neither my doughnuts or the Vicar's tea slowed them up at all! The lads are a credit to your organisation. Hard work with safe process obvious and the site was cleared and left tidy.”

We were contacted by the PCC to inspect a 20m high split horse chestnut tree following the loss of a large limb during recent windy weather. On inspection, the tree was found to be in an unsafe condition and it was agreed to remove it completely and grind out the stump.
Some of the timber was retained by the village to construct a Hibernaculum close by, and larger pieces were used by villagers for tabletops!

Thanks to Rev Tim for this time-lapse video; also starring Iggy and Gerri the sheep in the foreground.

“I’m very happy to recommend William Warden and his tree team. What a great
bunch of guys – it just works with the team all being ambassadors for William’s business –
courteous, thoughtful, empathetic to the environment and not noisy. And, of course, highly skilled
in their work. Good job done. Thank you. If anyone would like to speak to me personally, then
happy to do so”.

How We Reach Those Difficult Areas

The VOSCH grapple saw fitted to our Takeuchi 2150 excavator along with additional uprated hydraulics required to operate the saw and a bulletproof windscreen to protect the operator. This machine allows us to ensure dangerous ash trees can be managed safely and efficiently. Watch Video

Our Unimog - one of the range of multi-purpose auto four-wheel drive medium trucks produced by Mercedes-Benz –has a wood chipper on the back with a 1.5 ton capacity, so we're up for any tricky off-road areas you may have.

Our ‘go anywhere’ tracked chipper allows us not only off road but also to meet the majority of challenges where we’re needed to get into difficult areas. Whether narrow, uneven or sloping ground, soft ground conditions, we will be able to help.

We have three MEWPs (mobile elevated work platform) one reaching to 14m, one to 23m and the third reaching 25.6m. They are particularly useful for cutting high hedges and carrying out tree surgery where there is restricted access. - view MEWP page

Our 360 digger is perfect for the removal of individual trees, eg self-set alder trees - watch video

To reduce manual handling we have added a Reverse-Drive Valtra tractor with a cab-mounted timber Botex crane which allows us to move large pices of timber with relative ease and speeds up timber and brush removal

Our Dymax tree shear makes quick work of felled trees - watch video

Recycled Tree and Wood Waste

We always recycle our felled timber – recently it was used as part of a horse trial course and when chipped, it has been used by local farms on their cow tracks. If you need some wood chip, please get in touch.

​We take into account everything we produce, as what the client would consider waste we are able to recycle in some form or another, eg

  • Timber - processing for future use as board and structural building materials,  carving, logs.
  • Woodchip - garden mulch, compressed into pellets or loose for biomass boilers, rotted down and added as soil improver, or off by lorry to fire the power stations for fuel.  .

Nothing is EVER sent to landfill.
