It's important to make sure that the landscaping/treescaping company you hire is being run in a legal and ethical manner. It should be reputable and reachable, with clearly defined contact information.
Plenty of any companies offer cheap prices but provide low-quality service. Often, illegal and/or inexperienced workers are sent to a job site, only to damage a tree beyond repair. Unfortunately, with some trees, once they’re gravely damaged they can’t be healed.
Make sure the people you hire to work in your yard are covered by the proper insurance. There are documented stories of workers who have fallen from trees while on a job who have subsequently sued the homeowner. To avoid something like this happening to you, be sure to find out how long a company has been in business and ask to see their credentials, references, and legitimate proof of insurance. Keep in mind that anybody can generate false documentation on a computer, so exercise caution. When considering a company for insurance work (as in cases of storm damage, etc.), it’s better to work directly with the insurance company. Then you're sure to be covered.
Getting the best results means hiring the most skilled and experienced people. It pays to ask the company representative if their workers take classes to stay up-to-date on the skills, equipment, and techniques.
