Wood Fence FAQ

Is cedar still my best choice for wood fencing in St. Marys, IA?

In St. Marys, IA, homeowners should be aware that the cedar used in today’s fencing products is very different from what was available decades ago. Due to limited supplies of old-growth cedar and strict forestry regulations across the United States and Canada, most cedar now comes from fast-growing, younger trees. These trees develop very little heartwood—the dense, naturally durable inner portion—and are harvested at smaller sizes, resulting in lumber made primarily from lighter sapwood.

For properties in St. Marys, this difference matters. Sapwood cedar does not offer the same natural resistance to weather, insects, and decay that traditional heartwood cedar was known for. As a result, modern cedar fencing typically has a shorter lifespan and may require more maintenance to perform well through Iowa's seasonal weather conditions compared to the long-lasting reputation cedar once held.

Today’s cedar fencing from sapwood cannot hold up to its reputation as the preferred choice for longevity in exterior applications as its lifespan is considerably shorter compared to yesterday’s heartwood cedar fencing.

What are my options over cedar?

As old-growth cedar becomes harder to source due to harvesting limitations, the industry has shifted toward more abundant woods like Douglas fir, white fir, and incense cedar.

Harvested from older trees, these materials offer a higher concentration of heartwood, making them more durable for fencing. Douglas fir, in particular, often exceeds cedar in lifespan. While cedar’s scent is reduced, many appreciate a more subtle outdoor environment.

Is treated wood better than western red, incense cedar or Douglas fir?

Treated materials just can’t compare to the natural beauty of cedar and Douglas Fir. However, treated and stained white and red pine have proven to be an excellent choice for fence posts. Pine is a very dense wood that provides considerable strength. When treated with an ACQ or ACQ2 pressure treatment, the wood becomes almost impenetrable. Treated materials may be easily stained providing a darker color compared to your cedar and Douglas Fir rails and pickets. The contrast in colors does provide a nice combination.

However, red and white pine posts will form "checks" as the posts begin to dry after treatment. These checks are long thin cracks that form along the grain of the post. This is a natural process to be expected that does not compromise the strength or longevity of the post. You should only be concerned if these cracks dig deep through the post where you can see daylight.

Also, red and white pine posts are prone to twist slightly. Again, this is part of the natural maturation process of the material. This twisting is a result of uneven drying of the post. It does not compromise the quality or longevity of the post.

Do I need to stain my Douglas fir or cedar fence?

To preserve the natural cedar appearance of your fence in St. Marys, IA, stain it within six weeks after installation. Make sure the wood has dried thoroughly—usually after a rain-free week. Dry conditions in Iowa help the stain soak in properly.

Hire an insured contractor in St. Marys to avoid overspray issues that can affect nearby surfaces. Always stain during calm weather and protect surrounding structures and landscaping with tape and drop cloths.

Brushing can be challenging on rough wood, while rolling may cause drips. Spraying is often the most efficient method. For best results, spray and then back-brush to even out the application.

Apply stain in smooth strokes. If applying more than one coat, the second should be applied before the first dries to ensure proper adhesion.

Plan to re-stain every 2 to 3 years. Keep sprinklers from hitting the fence regularly to avoid uneven fading. Both cedar and Douglas fir will gray over time without maintenance.

Why is cedar fencing so popular in St. Marys?

Forty years ago, cedar fence boards were rich with dark orange, red, and brown hues. The boards also had a very strong, unmistakable strong cedar smell. Back then, cedar fencing came from old growth cedar trees. When the trees were harvested, the trunks were as big around as a car, mostly comprised of heart wood with a few outer sapwood rings.

What is the difference between sap wood and heartwood?

The pale outer rings of a tree, referred to as sapwood, function as the main conduit for water and nutrients. While essential to the tree’s survival, sapwood is not ideal for fencing because it holds more moisture, shrinks more during drying, and is more prone to decay.

The inner, darker heartwood forms as sapwood ages and becomes inactive. This portion of the tree provides structural strength and is far more resistant to the elements. Heartwood’s lower moisture content and natural durability make it the better choice for fencing, and many mills use only this portion.

As sapwood transitions into heartwood, sap movement stops, and the cells fill with extractives. These natural compounds are responsible for the deeper color, characteristic scent, and improved resistance of heartwood.

Should I use cedar or treated pine fence posts?

If the concrete footing is placed to shed water from the posts, cedar or treated pine is fine. We will use premium cedar post or ACQ2 treated and stained posts. Though the treated pine posts are subject to forming checks and a slight twist, these posts have proven to outlast cedar. Cedar is less prone to form any cracking or twisting but it will occasionally warp. If not stained, cedar posts will eventually “grey out”.

Are treated materials safe for my family and pets?

Only use industry approved ACQ treated posts. Stay clear of using CCA (Cooper Chromate Arsenic) materials. If unsure how the materials are coated, look for a tag at either end of the post or inquire with your fence contractor.

What about Wood Gates?

Only use a heavy duty 4” x 6” posts on the hinge side of your 6’ tall gate. We recommend using three hinges per gate. Make sure all hardware is powder coated to avoid rusting.

Will I have maintenance issues with my wood gates?

Gates are set with two independent gate posts on opposite sides of your gate opening. Gate posts are subject to settling of unsettled soil, frost, extreme changes in temperatures, and exposure to the sun, which can cause gate posts to change or move. Even the slightest change in the position of the hinge post will result in an exponential movement of the latch hasp on the gate. Bottom line, your gate won’t latch because the latch hasp does not align with the latch receiver on the gate post.

What can I do to fix my gates?

The classic drop fork latch, with its vertical two-prong design, is not affected by shifting gate posts and typically continues to operate smoothly. Latches that use a horizontal rod or resemble standard door locks are more prone to misalignment and may require adjustment. For these setups, four-way adjustable hinges are a smart solution, offering both vertical and horizontal adjustments.

What nails do I need for my wood fence?

A galvanized or aluminized nail that is counter sunk to avoid popping-out is your best bet.
