Landscaping companies have residential and commercial clients as both of the categories have needs of having their landscapes beautified. Many people confuse landscaping with gardening but that is a misconception. Landscaping services not only include maintenance of trees and other plant life but also designing aspects of the features of a particular land. Many people do not need such extravagant services which is why they stick to simple landscaping companies that offer services like tree cutting, maintenance, trimming, pruning etc.
There are many good companies like twitter.com/marietta_tree that have been in the industry for a long time and have a strong team that is made up of skilled arborists that perform their jobs perfectly. If you end up hiring arborists that do not know how to do their job, you will end up with a landscape that is ruined. We would recommend that you cleverly pick out a company and not fall for ones that offer suspiciously cheap rates.
One way of finding out a good company of arborists is to look at the testimonials or reviews left by previous clients as that will tell you a lot. You need to keep in mind that every company will have some not so positive reviews but that just means that they might have made a few mistakes, not that they are bad companies. Only consider those companies that have majority of positive reviews.
If you are looking for extravagant and special services then choose a company that offers a portfolio or collection of their previous work done. This will allow you to see their work and also tell you how vast their experience is in the field.
The company should have insurance and permit to do the job so make sure that you ask to see it.
