Depending on the fence materials chosen you can expect most styles posts to be set in concrete up to 36″ depending on terrain and what is beneath the surface. In Berks County there are a lot of rock formations, shale etc. which can impact installation. Oftentimes this is not apparent until the time of excavation. Please see the digging/rock clause in your written estimate.
We try to keep the fence off the ground about 2- 3” in ideal circumstances. The slightest change in grade or a sloping yard will affect this.
If you prefer a more even look to the top of the fence the bottom may be considerably off the ground in sloped areas.
Ground slope and grade changes are critical to the placement of gates. We will help you determine the best location in the yard.
