Pros And Cons Of Pressure Treated Fencing
Pressure treated fencing is a popular choice due to its affordability and resilience. The treatment process involves infusing wood with preservatives that protect it against rot, decay, and insect damage, making it an ideal option for withstanding harsh environmental conditions. Note: modern pressure treated lumber uses ACQ (alkaline copper quaternary) or CA (copper azole) treatments — the older CCA (chromated copper arsenate) was phased out for residential use in 2004.
- Pros of Pressure Treated Fencing:
- Cost-effective — $2–$5 per linear foot vs $6–$8 for cedar
- Superior ground contact durability (PT posts outlast cedar posts every time)
- Available in a variety of finishes and styles
- Cons of Pressure Treated Fencing:
- Green tint from copper preservatives — less attractive than cedar
- Can require periodic staining or sealing every 2–3 years
- Potential warping or splitting as the wood dries after treatment
Comparing Cedar and Pressure Treated wood for fences, Cedar’s natural durability and longevity make it a top choice for above-ground applications. Its resistance to rot and decay minimizes maintenance needs while providing a sustainable, attractive option for long-term fence structures.
Durability and Longevity
When it comes to choosing the right material for your fence, considering the durability and longevity is crucial. Both cedar and pressure treated fences have their own benefits in terms of lifespan, structural integrity, and resistance to decay. Let’s take a closer look at the lifespan of these two popular fencing options.
Lifespan Of Cedar Fencing
Cedar fencing is widely known for its natural durability and resistance to rot, decay, and insects. The inherent properties of cedar wood, such as natural oils and tannins, contribute to its longevity. With proper maintenance and care, a cedar fence can often last upwards of 15 to 30 years, making it a durable and long-lasting option for homeowners.
Lifespan Of Pressure Treated Fencing
Pressure treated fencing is specifically treated with preservatives to enhance its resistance to decay, termites, and fungal decay. This treatment process significantly extends the lifespan of the wood. Typically, pressure treated fences can last anywhere from 20 to 30 years, making them a durable and long-lasting choice for outdoor structures.
In comparing the two options, both cedar and pressure treated fencing offer impressive durability and longevity. Understanding the specific lifespan of each material can help homeowners make informed decisions when selecting the right fence for their property.
Which Is Better for Fence Posts: Cedar or Pressure Treated?
Pressure treated pine is the clear winner for fence posts — any wood that contacts soil needs maximum rot resistance, and PT lumber delivers it. Cedar’s natural oils work above ground, but below the soil line, moisture and bacteria break down cedar posts faster than PT pine. Most fence contractors recommend this hybrid approach: pressure treated 4×4 posts set in concrete, cedar pickets and rails for everything visible above ground.
| Feature | Cedar Pickets | Pressure Treated Pine Posts |
|---|---|---|
| Best use | Above-ground boards, rails, pickets | In-ground posts, ground contact |
| Lifespan | 15–30 years | 20–30 years (posts: 40+ years) |
| Cost per linear foot | $6–$8 | $2–$5 |
| Appearance | Warm natural grain, stainable | Greenish tint, less attractive |
| Rot resistance (above ground) | Excellent — natural oils | Good — chemical treatment |
| Rot resistance (in ground) | Poor — posts rot faster | Excellent — designed for soil contact |
| Environmental impact | Renewable, biodegradable | Copper-based chemicals in soil |
For pressure treated pine specifically versus cedar, pine is denser and heavier but takes the chemical preservatives deeply into the wood grain. According to the American Wood Protection Association (AWPA), pressure treated lumber rated UC4A or UC4B is required for any wood in ground contact — cedar does not meet this rating without additional treatment. If you’re staining your fence, cedar accepts stain beautifully; PT pine needs to dry for 6 months before stain will adhere properly.
Maintenance And Upkeep
Maintenance and upkeep are essential factors to consider when choosing between cedar and pressure-treated fences. Both options require care and attention to ensure longevity and durability. Understanding the specific maintenance needs of each type of fence is crucial in making an informed decision.
Care And Maintenance For Cedar Fences
Cedar fences are known for their natural beauty and durability. To maintain the appeal and structural integrity of cedar fences, applying the right fence stain and proper care is necessary. Here are some key maintenance tasks for cedar fences:
- Regularly inspect the fence for signs of damage, rot, or insect infestation.
- Apply a protective sealant every 2–3 years to enhance the wood’s resistance to moisture and decay.
- Clean the fence periodically to remove dirt, debris, and mildew using a gentle cleaner and soft brush.
- Trim any nearby vegetation to prevent overgrowth that can cause moisture retention and damage to the wood.
Care And Maintenance For Pressure Treated Fences
- Regularly inspect the fence for signs of damage, particularly at the ground level where moisture can accumulate.
- Apply a water-repellent stain or sealant every 2–3 years to enhance the fence’s resistance to moisture and UV damage.
- Clean the fence using a mild detergent and water to remove dirt, mold, and mildew, especially in shaded areas.
- Ensure proper drainage around the fence to prevent water accumulation near the posts and base.
Environmental Impact
When considering installing a fence, it’s important to weigh the environmental impact of different materials. Cedar and pressure-treated wood are two popular choices for fences, each with its own set of benefits and drawbacks. Understanding the sustainability and environmental implications of these options can help you make an informed decision that aligns with your values and green initiatives.
Sustainability Of Cedar Fencing
Cedar fencing is known for its sustainability due to the renewable nature of the cedar tree. Cedar grows relatively quickly, making it a highly renewable resource for fencing materials. The harvesting of cedar for fencing purposes is generally managed in a sustainable manner to ensure that it remains an abundant resource for future generations.
Environmental Implications Of Pressure Treated Fencing
Pressure treated fencing, on the other hand, comes with environmental concerns. The most common treatment chemical historically — chromated copper arsenate (CCA) — was phased out for residential use in 2004 due to arsenic leaching concerns. Modern ACQ and CA treatments are safer, but copper-based chemicals can still leach into surrounding soil over decades. Cedar decomposes naturally at end of life; pressure treated lumber requires special disposal in many municipalities.
Cost And Budget Considerations
Cedar and pressure treated wood are popular choices for fencing due to their durability and ability to resist rot and insect damage. When deciding between the two options, cost and budget considerations play a significant role in the decision-making process.
Initial Cost Of Cedar Fencing
Cedar fencing typically costs $6–$8 per linear foot, higher than pressure treated options. This premium reflects cedar’s natural rot resistance without chemical treatment, its aesthetic appeal, and its lower long-term maintenance cost. Despite the higher initial investment, cedar fencing often proves more cost-effective over 20+ years due to low maintenance requirements.
Initial Cost Of Pressure Treated Fencing
Pressure treated fencing costs $2–$5 per linear foot — roughly 30–50% less than cedar upfront. The wood is treated with preservatives, making it resistant to decay, rot, and termites. While the upfront cost is lower, factor in periodic staining and sealing costs over the fence’s lifespan, which can narrow the cost difference significantly over 20 years.

Which Fence Type Is More Eco-friendly, Cedar Or Pressure-treated?
Cedar is considered more eco-friendly compared to pressure-treated wood, as it is a renewable resource that requires minimal processing. Cedar also decomposes naturally, posing less harm to the environment, while some pressure-treated woods contain chemicals that may leach into the soil over time.
Are There Cost Differences Between Cedar And Pressure-treated Fences?
Yes — pressure-treated fencing costs $2–$5 per linear foot, while cedar runs $6–$8 per linear foot. When considering long-term maintenance and replacement costs, cedar fences often prove more cost-effective due to their durability and natural resistance. Investing in a cedar fence can ultimately save money in the long run.
Should I Use Cedar or Pressure Treated Wood for Fence Posts?
Use pressure treated posts for any wood that goes in the ground — PT lumber rated UC4A or UC4B is specifically designed for soil contact and will outlast cedar posts by 10–20 years. Above ground, cedar pickets and rails look better and resist rot naturally. The hybrid approach (PT posts + cedar pickets) gives you the durability of PT where it matters most and the appearance of cedar where it shows.
Can You Mix Cedar and Pressure Treated Wood in the Same Fence?
Yes — mixing cedar pickets with pressure treated posts is the approach most professional fence contractors recommend. The PT posts handle the in-ground rot risk, while cedar pickets provide the natural, attractive appearance above ground. Use stainless steel or hot-dipped galvanized fasteners when mixing the two materials, as untreated hardware will corrode faster when in contact with PT lumber’s copper-based preservatives.
Conclusion
When deciding between a cedar or pressure-treated fence, weigh the pros and cons carefully. For above-ground appearance and natural rot resistance, cedar wins. For in-ground posts and budget-conscious projects, pressure treated pine is the better choice. The smartest approach — PT posts with cedar pickets — combines the structural durability of pressure treated wood with the natural beauty of cedar for a fence that looks great and lasts 30+ years.
