First, you must consider the contractors in your area, and take into account how long they have been established. It's better to use a local company because they want to uphold their reputation for their own area so as to provide you with good service. Have a look at www.allislandfence.com/ if you are looking for the fencing contractor.
Why not call them, you can tell them that you want to install a fence but contact your local contractor to find out their workloads, etc.

Don't be afraid to ask lots of questions, satisfy yourself by talking about your garden fence project and what types of materials are available, what styles are available, whether the fence has been processed beforehand, etc.
Arm yourself with information on how many panels are needed or the length of the fence needed.
It gives you information so you can talk to contractors and get a general feeling about the company.
Why not ask if you can see one or two of the most recent work that he has completed in your local area so you can see the type of material used and workmanship.
Any reputable company will be happy to show you some of its newest works.
Ask if they have a website so you can see various details about the company and see some of their works and different types of fences.
Take your time, after you are happy with the company if you decide to continue, make sure you get a written offer before the work begins.
That way there is no difference because he has to provide detailed information about the material to be provided, etc.
