Cedar fencing is one of the most popular choices for Seattle homeowners, and for good reason. Its natural beauty, durability, and versatility make it ideal for Pacific Northwest properties. But there’s one major challenge: Seattle’s wet climate can cause traditional wood posts to deteriorate, settle, and fail more quickly than in drier regions.
At DH Fence Pros, we’ve been installing post-on-pipe cedar fences across Seattle for over 25 years. This proven system combines the beauty of cedar with the strength of galvanized steel, giving you a fence that lasts significantly longer when properly maintained.
What is Post-on-Pipe Fencing?
Post-on-pipe fencing uses galvanized steel pipes embedded in concrete as the foundation, with cedar posts mounted on top.
Here’s how it works:
- Steel pipe is set in concrete below ground (away from soil moisture)
- Cedar 4×4 posts are mounted above ground on the steel pipe
- Fence panels attach to cedar posts for a natural wood look
This hybrid system provides the classic appearance of cedar while eliminating the main weakness of traditional fences: ground-line rot and deterioration.
Why It’s Ideal for Seattle’s Climate
In fact, Seattle receives an average of 38 inches of rain per year. Constant moisture means traditional cedar posts buried in the soil are prone to:
- Moisture absorption and decay at the ground line
- Rot and fungal damage
- Insect activity (termites, carpenter ants)
- Settling and leaning over time
Additionally, post-on-pipe technology prevents these issues by keeping wood entirely above ground, protecting it from soil contact and moisture.
Key Benefits of Post-on-Pipe Fencing
1. Extended Lifespan
- Lasts 25 to 30+ years compared to 10 to15 years for traditional cedar posts.
- Performance depends on quality installation, maintenance, and environmental conditions.
2. Reduces Rot & Insect Damage
- Galvanized steel pipes don’t rot or attract pests.
- Keeps wood dry and elevated, extending structural integrity.
3. Superior Stability on Sloped Terrain
- Perfect for Seattle’s hilly neighborhoods like Magnolia, Queen Anne, and West Seattle.
- Concrete-set steel foundations improve stability and alignment.
4. Low Maintenance
- Minimal structural upkeep.
- Simply stain or seal cedar every 3 to 5 years to maintain appearance.

How long does a post-on-pipe fence last in Seattle?
Post-on-pipe fences typically last 25 to 30+ years, much longer than traditional cedar fences. The galvanized pipes prevent rot, while cedar posts stay dry and elevated.
Is post-on-pipe better than regular cedar posts?
Yes. It eliminates ground-line rot by separating cedar from the soil, resulting in longer lifespan and better stability, ideal for Seattle’s wet conditions.
Does post-on-pipe work on sloped yards?
Absolutely. The steel-pipe foundation provides excellent stability on Seattle’s hilly terrain, including West Seattle and Queen Anne.
How much does post-on-pipe fencing cost in Seattle?
It costs more upfront than standard cedar fences due to materials and specialized installation, but the long-term durability and lower maintenance make it a smart investment.
What maintenance does it need?
Only minimal care is needed. Just stain or seal the cedar every few years to preserve color and protection. The steel base requires no maintenance.
