You can definitely build a fence in winter, and for a couple of good reasons. First of all, you need to make sure that the earth is not frozen yet, before you embark on any building activity for your fencing system.
One good reason for choosing the cold season to build your fence is the fact that most trees and shrubs go through a period of hibernation. So in case you have trimmed your trees and other plants around your yard, building a fence can be a very good idea. Thus, you no longer have to worry about harming your plants in any way.
Another great reason is the fact that in demand Westminster fencing contractors can work at a higher speed than in other seasons, because they usually have less work and therefore getting the job done quickly is to their own advantage also.
At the same time, if you build your fence in winter, you are actually preparing your home and household in general for any kind of harsh weather. Once you have your fence installed, you can enjoy your cozy winter season inside your home, no longer having to worry about staying outside, to supervise the job, and help with building your fence, and so on.
