Those of us with property which has some mature plants and shrubs etc may need some help if the plant life becomes diseased and needs removing. Deep roots and stumps are very difficult to get out since they sometimes go very far into the ground and needs some specialist help to get it all out. For those with this kind of problem, try looking up 'tree service' or 'tree removal' to find out which company can undertake this kind or work.
These experts are needed when the disease is killing off the plant to the point where it could keel over and damage the house or persons living there. Even overgrown plants need some surgery sometime and this surely needs an expert eye if the offending plant is to stay looking good. If they are also near other buildings, or overhanging into the garden next door, then this must be attended to. Indeed, the neighbor has every right to chop off any branches which overhang into the garden and any fruit or produce on the branches belongs to him anyway. This can bring up many disputes so it is imperative to keep the garden in good shape so as to keep up a good relationship with them in the long run.
Although there are many opportunistic people who say that they can do this work at ultra low rates, it may be better to look for a professional company since they will be fully insured against accidental damage. One such case comes to mind where the local handyman offered to cut down an old conifer that was dead. Although he thought the work was not that difficult, what he underestimated was the weight of the thing and how it was distributed. Eventually it started to fall, the wrong way, and caused untold damage to both the family car and the house itself!
Professional companies would not really do this, of course, and if something happened accidentally, their insurance company would cover all the damage. But they also offer another service and that is to pick up all the loose debris, chop up the branches and leave them for burning, if there is a wood stove in the house, or take them away and dispose of them properly. This would be unlikely to happen in the case of the local handyman for sure.
When choosing this kind of company, ask neighbors and friends if they have used this kind of service before. Indeed, this is probably the best way to work out if the company is a good one or not. Failing that, look online to see what the website says about it all and check out certificates and qualifications if necessary before signing any contracts. Good companies will always offer a site visit first to see the extent of the job at hand and will sometimes pick out other work which may be imminent which the householder has not really noticed. They may even offer a discount for this other work so this may well worth a try.
