The Truth About Pressure-Treated Wood for Fences in Richmond Hill

When it comes to installing a durable and long-lasting fence in Richmond Hill, homeowners often ask: Can you use pressure-treated wood for fencing? The answer is yes, but there are key considerations to ensure your fence stands strong for years, especially in Richmond Hill's variable climate.

​
Can You Use Pressure-Treated Wood for Fencing?

Yes, pressure-treated wood is one of the most popular choices for fencing in Richmond Hill. It's designed to resist rot, insects, and moisture, making it ideal for Ontario’s weather patterns. Homeowners in neighbourhoods like Bayview Hill, Mill Pond, and Jefferson have successfully used pressure-treated wood to create attractive and durable fences that withstand seasonal changes.


Can Pressure-Treated Wood Be Placed Directly on the Ground?

While pressure-treated wood can touch the ground, it’s not ideal for extended durability. In areas like Yongehurst or Langstaff, where soil moisture is high, placing wood directly on the ground may accelerate decay. Using gravel or concrete footings beneath the posts can significantly improve longevity.


Does Pressure-Treated Wood Fence Need to Be Sealed?

While pressure-treated wood is treated to resist rot and insects, sealing it adds an extra layer of protection. For homeowners in Richmond Hill’s Crosby and North Richvale communities, applying a high-quality sealer every couple of years can extend the life of your fence by protecting it from UV damage, moisture absorption, and cracking.


Will Pressure-Treated Wood Rot If Buried?

Pressure-treated wood is designed to resist rot, but prolonged exposure to damp soil can still cause decay over time. For Richmond Hill properties with poor drainage—common in areas like Oak Ridges—it’s important to elevate posts above grade or improve drainage to prevent water from pooling around the base.


What Should Never Be Done with Pressure-Treated Wood?

• Avoid Burning It: Burning pressure-treated wood releases harmful chemicals into the air.
• Don’t Skip Post Protection: When installing posts, coat the base with bitumen paint or wrap the portion that will be buried to prevent moisture from seeping in.
• Avoid Using Indoor Sealers: Always choose sealers designed for outdoor pressure-treated wood.

How Long Will a Pressure-Treated 4x4 Post Last in the Ground?

With proper installation and maintenance, a pressure-treated 4x4 post can last 15 to 20 years or longer. In Richmond Hill's diverse landscape, properties in Heritage Estates or along Bathurst Street may experience different ground moisture levels, so ensuring proper post preparation and sealing is crucial for longevity.


Case Example: Pressure-Treated vs. Untreated Fence

In North Richvale, two neighbours, Tom and Alex, both decided to install new fences around the same time. Tom chose a pressure-treated wood fence, while Alex opted for untreated cedar to save on upfront costs. Initially, both fences looked fantastic, but after just three years, Alex's untreated fence began to show signs of rot and insect damage. Meanwhile, Tom’s pressure-treated fence remained sturdy and attractive, thanks to its enhanced resistance to moisture and pests. By year five, Alex faced the costly task of replacing several damaged panels, while Tom's fence only needed a quick cleaning and resealing to keep it looking fresh. This real-life story shows how investing in pressure-treated wood can save Richmond Hill homeowners time and money in the long run.
