Planning and purchasing: Choose the right fence for your needs and budget

Planning and purchasing a plastic fence requires careful consideration of your specific needs and budget. Here are some key factors to keep in mind:

First, determine the purpose of your fence. Do you need privacy, or is it mainly for decorative purposes? Privacy fencing, for example, provides a solid barrier and is commonly used around swimming pools or between properties. On the other hand, picket fencing is ideal for keeping children and pets in the yard while still maintaining a distinctive look and aesthetic appeal.

Next, consider the terrain. If you're installing the fence on a slope, you'll need to use the step method, ensuring that each bay section is the same length and the rails are level instead of parallel to the slope. This method requires careful horizontal measurements for accurate post placement.

Then, decide on the type of material. Vinyl fencing is a popular alternative to traditional wood pickets or rails. It is maintenance-free, durable, and not subject to rot or fading from weather exposure. However, it typically costs more upfront than wood or chain-link fencing. If you opt for vinyl, choose a neutral colour that will complement any future landscaping or exterior paint choices.

Finally, plan your budget. Consider the cost of materials, taking into account the length and height of the fence you require. Don't forget to include the cost of any necessary tools or equipment rentals, such as a post-hole digger or power auger. Additionally, factor in any permits or inspections that may be required, as regulations vary depending on your location and the height of the fence.

By carefully considering these aspects, you can make informed decisions during the planning and purchasing stages of your plastic fence installation project, ensuring it aligns with your needs and budget.

Measuring and marking: Use stakes and string to define the fence line

When installing a plastic fence, one of the first steps is to carefully measure and mark out your fence line. This will ensure that your fence is straight and avoid any problems that could arise from incorrect measurements. Here is a guide on how to do this using stakes and string:

Start by installing landscape stakes along your desired fence line, from beginning to end, including corners and any gates. Make sure to hammer the stakes into the ground clearly away from where your post holes will be, so that the stakes are not disturbed during the digging process. Install your stakes relative to all corners, ends, and changes in grade, ensuring that they are no more than 6 inches above the grade. Your stakes should be at least 18 inches long to ensure proper burial and stability during installation. If your fence line includes a slope, you will need to take horizontal measurements for post placement, rather than measuring parallel to the ground slope.

Next, tie a string tightly between the stakes at your corner post locations. This will create a straight line that defines the placement of your line posts. The string should represent the outside of your fence, not the centre, as this is where your fabric will be installed relative to the posts. Ensure that the string is pulled taut and is as thin and lightweight as possible to reduce sagging and the impact of wind.

Once your string is in place, measure your panels and stake out the line post locations using the same measurements as the length of your panels. For example, for 6-foot fence panels, use 5-inch-by-5-inch posts placed 73 1/4 inches apart on centre. By following these steps, you can accurately define your fence line and ensure that your plastic fence installation is straight and secure.

Digging holes: Dig holes for posts, ensuring they're deep and wide enough

Digging holes for your plastic fence posts is a crucial step in ensuring the stability and longevity of your fence. Here are some detailed instructions and considerations to guide you through the process:

First, it's important to carefully plan the layout of your fence. Measure and stake out your fence line, including corners and gates. This will help you determine the exact locations of your post holes. Remember to take into account the widths of the fence panels and gates to avoid odd-sized bays that can complicate installation.

When determining the depth and width of your post holes, there are a few rules of thumb to follow. The general rule is that the depth of the hole should be one-third to one-half of the above-ground height of the post. For example, if you're installing a 6-foot-high fence post, a common depth would be 36 inches (3 feet) for a standard fence. However, if you're dealing with soft ground or high winds, it's advisable to go deeper, up to 4 feet, for added stability.

The width of your post hole should be three times the width or diameter of your post. For instance, if you're using a 4-inch post, your hole should be 12 inches in diameter. Additionally, make sure to bell" the bottom of the hole, making it slightly wider than the top. This helps prevent the post from heaving due to frost.

To dig the holes, you can use a standard shovel, but keep in mind that the hole will be as wide as the shovel, which may not be the desired width. Alternatively, consider using a post hole digger or a power auger, especially if you have a large number of holes to dig, as it will save time and effort. The standard diameter for a post hole auger is 10 inches, which is suitable for most fence posts.

Before you start digging, be sure to check for any underground utilities, such as electric cables, water pipes, or gas pipes, to avoid any accidental damage. Call your local utilities to mark any underground wires or pipes. Additionally, always adhere to local codes and obtain any necessary permits before beginning any construction work.

Setting posts: Fill holes with concrete and tap posts into place

Setting posts in concrete is a crucial step when installing a plastic fence. Here's a detailed guide on how to do it:

First, dig the holes for your fence posts. The holes should be deeper and wider than the posts themselves. As a general rule, dig the holes about one-third deeper than the length of the post. For added strength, make the holes for the main posts and any gate posts about 6 inches deeper. It's important to ensure the holes are wide enough, especially if you're using large posts. A post-hole digger or power auger can be used to dig the holes, and the recommended diameter is 10 inches.

Once the holes are dug, fill them with gravel to a depth of about 6 inches. This layer of gravel will help drain water away from the posts once the fence is installed. After adding gravel, it's time to set the posts in place. Fill each hole with quick-setting concrete, ensuring it's level and secure. Work on one hole at a time so the concrete doesn't dry out too quickly.

Now, carefully tap the posts into the wet concrete, starting with the end and corner posts first. Use a level to ensure the posts are straight and properly aligned. It's important to work quickly but carefully during this step, as you'll need to adjust the posts before the concrete sets. Once the posts are in place and level, allow the concrete to cure completely.

After the concrete has set, you can proceed to the next steps of installing your plastic fence. This may include attaching rail brackets, sliding panels into place, and reinforcing the posts for added stability. Remember to refer to the specific instructions provided with your fence for the best results.

Attaching panels: Slide panels into place, securing with screws and brackets

Attaching the panels is a straightforward process once the concrete has set and the posts are ready. First, attach the rail brackets to the fence posts, following the manufacturer's instructions and using the recommended screws and brackets. Next, simply slide the panels into place along the rails. Secure the panels using the supplied screws and brackets.

It is important to ensure that the panels are straight and level as you work. Once the panels are in place, tighten up all the posts, rails, and pickets to make the fence stronger. If desired, you can also apply vinyl adhesive to the post tops for added security and durability.

For even greater strength and stability, you can reinforce the posts with concrete. This is particularly recommended if your fence is in an area prone to strong winds. However, this may not be necessary for all installations, especially if you have already set the posts in concrete.

Finally, it is always a good idea to check local regulations and permit requirements before installing a fence. Requirements can vary depending on your location and the height of the fence. It is better to be informed before you begin construction to avoid any potential issues or non-compliance.
