Q: How far do you travel to carry out work?

We routinely carry out work for customers across North / Mid Wales and the North West of England. We also carry out work for customers across the rest of England, in Scotland and as far away as Sweden. If you have tree work that you would like us to provide a quote for but you think you are too far away from us, then please call us and we will be happy to discuss this with you. As you can see above, distance is really no problem.


Q: Can I receive a quotation over the phone?

The difficulty we face when trying to advise clients of the cost of tree work over the phone is that every tree is growing in a different environment and is surrounded by different natural or man-made features. For us to accurately advise you of the cost of any required tree work we would first need to visit and assess the extent and method of work. This is a free, no obligation service. During the site visit we will discuss with you what exactly it is you would like done, advise should you have any uncertainties and come up with a plan of work. We also take the opportunity to consider what machinery and equipment we will use to ensure the work is carried out as efficiently as possible.


Q: What if my tree has a Tree Preservation Order on it or I live in a Conservation Area?

A Tree Preservation Order (referred to as a TPO) is an order made by a Local Planning Authority (LPA) in respect of trees or woodlands, and can be placed on any tree.

Conservation Area (CA) works require that anyone proposing to cut down or carry out work on a tree in a Conservation Area give the LPA six weeks prior notice (a section 211 notice). This gives the LPA time to consider their response and reply to the applicant if necessary.

We act as agents for clients in these matters should they wish us to make applications and correspond with the LPA on their behalf.


Q: Can I use the wood chip from my trees?

Yes. We regularly process branches through a wood chipping machine allowing them to be used as garden mulch in due course. In fact, by us not transporting this material away from site there is often a cost saving to the customer too.

We will advise you of the suitability of us doing this on a case by case basis as not all woody material should be used as a garden mulch for a variety of reasons.


Q: Why should I hire a qualified Arborist / Tree Surgeon?

By hiring suitably qualified and experienced Arborists (Tree Surgeons) such as CRAiG Tree Services you can have the peace of mind that any work we carry out will have been carefully considered and that it will be carried out to the highest standard. We will always work in accordance with the British Standard for Tree Work BS 3998: 2010 if possible. All members of our team who carry out work on your trees will be suitably qualified for the task in hand, they will be covered by our comprehensive insurance policies and they will care about what they are doing.


Q: How can I tell if my tree is hazardous?

It is a property owner's responsibility to provide for the safety of trees on his or her property.

Some tree owners are happy to carry out a visual inspection of their trees, others choose to employ the services of a suitably qualified Arborist to do this for them. We are trained and qualified to assess trees for defects and then provide recommendations based on our findings.

There are a number of common defects associated with trees which are:

Cracks or cavities on the stem or main branches

Roots which are damaged or broken

Neighbouring trees dead or dying

Cracks or splitting occurring where 2 branches meet

Fungal Fruit Bodies (Mushrooms) present at/around base of tree

The tree has recently developed a pronounced lean

The action to be taken once a defect has been detected can take many forms, depending on what it is the owner wants from their tree(s). 


Q: Do mature trees need special care?

Mature trees will often be large in size. Whilst this can present a specific set of management requirements the aesthetic value of a large tree in the environment is one which can not be bought or replaced. The management of these trees requires a knowledge of how trees function, how they grow and how they ultimately die. We can bring this understanding when asked to inspect and report on your mature trees, or when working on your mature trees and recommend a long-term management approach which considers what you want from your trees. We assess the trees current health by looking at the quality of the ground the roots are growing in, note the condition of the stem/trunk and main branches, comment on the twig growth, leaf size, buds and the overall appearance of the tree. We often assess trees the customer thinks are ‘dying’, but which in fact are naturally ‘retrenching’ or simply making themselves smaller as they grow old. We are able to carry out specialist work on such trees and can provide detailed recommendations of such work in a report.


Q: When is the best time of year to have work carried out on my trees and hedges?

There are recommended times of the year to have work carried out on certain tree species such as Plum, Cherry and related trees such as Prunus. It is recommended that these species are pruned soon after flowering to lessen the chance of infection by a bacterial infection. Many other species are recommended to be have work carried out on them after leaf fall or before bud burst. Birch and Maple have a tendency to ‘bleed’ (exuding sap) if pruned in the spring due to the rising sap but this is considered to be more of an unsightly problem rather than anything more serious, and there is a suggestion that this ‘bleeding’ may actually help keep bacterial or fungal infection from entering the tree. Our tree inspector will assess each tree individually during a site visit and provide recommendations based on their findings.


Q: How long will it take you to carry out the work?

We always aim to carry out work as soon as possible, during busy periods we tend to work on a 2-4 week turn around, this means that if you call us tomorrow the tree work should be carried out in 2 weeks, but it may take up to 4 weeks. There are time delays involved with tree work applications involving the council and this can add anywhere from 4-8 weeks to the timescale.
