The information in this article is general and can apply broadly to many fence styles, but you might want to find specifics on your fence style to compliment these instructions.
You can search for Property\Survey Pins on your property. These are also located on the corners of a lot. Just because an old fence or other “assumed” property boundary was\is in place that does not always mean that it is correct.
Most cities have a height ordinance, so be sure to check this before you choose your fence height.
You can also square the corners by measuring the strings. Measure 3’ on one side and 4’ on the other. If the distance between the two marks (diagonally) is equal to 5’, then the corner is square.
You generally want to take the total distance and divide it by 8 but if you have a length of fence that is not divisible by 8, you’ll need to break it down into smaller sections. For example, a 24’ fence would need 2 middle posts to create the three 8’ sections, but a 25’ fence would need 3 middle posts at 6. 25’ for each section in order to look even and be structurally sound. To find the length and number for odd fence lengths, go up to the next number of posts and then divide the total length of the fence by the number of resulting sections.
The hole should be wide enough that there is room around the post when you put it in. Because soil conditions vary, and the height of the fence, the type of fencing, and other factors must be considered in determining how deep the post should be, you will have to calculate the hole depth for yourself.
These boards are usually 1X6 rough sawn lumber but you can buy other pre-cut fencing boards as well. If nailing the boards by hand, use 8d spiral shank galvanized nails.
This will usually either contain silicone solids, or linseed oil. If you plan on painting a finish paint, stick with an oil-based sealer, and use an oil-based polyurethane paint or exterior enamel for the finish paint.
