Fence damage is very common. Many fences are not properly engineered with lawn mowing in mind. If your fence has pickets with grass going along them instead of some kind of runner it is very common for trimmer line from the weed eater to create a line and eventual divot in the fence pickets that gets worse over time. A board on board fence makes this even more likely if there is not a runner at the bottom of the fence.
Gates are the most common area of damage. If you ever have a question about your fence and potential damage please contact our office right away and we will have someone out to assess the damage and set up any repairs if needed.
