9 Best Wood for Exterior Columns & Porch Posts
- Red or white oak
- Douglas Fir
- Cedar Column
- Yellow pine
First things first: What are Exterior Columns?
Columns, also popular as pillars in architecture and structural engineering, are structural elements that transmit, via compression, the weight of the structure above to other structural elements below.
For example, a standard exterior column supports beams or arches on which upper parts of the wall or ceiling rest.
Benefits of Exterior Wood Columns Porch?
Exterior columns are beneficial for many reasons. For example, although they primarily support structures, they also serve decorative purposes. However, standard exterior pillars serve four main purposes as follows;
- Excellent supporting structures: The main purpose of exterior columns is to support porch and deck roofs. The right column structures can handle a decent amount of weight, thus supporting porch and deck roofs for many years without faltering.
- Aesthetic appeal: Many people like exterior columns, pillars, and exterior wood shutters because they elevate exterior aesthetics. Decorated columns, such as capitals that feature flourishes and accents, significantly improve the property’s outlook. Enhancing your exterior columns with LED lighting products can transform your porch into a striking and inviting space. These energy-efficient lights not only accentuate the wood’s natural beauty but also create a welcoming ambiance.
- Different designs: One of the main reasons structural columns make excellent decorative features is that they come in varied styles and designs. For instance, you can opt for a stone or wooden pillar system. Alternatively, you can choose fiberglass. Additionally, you have a wide range of shapes and styles from which to pick.
- Durable: Finally, homeowners also love structural columns because they are durable. This is especially true for homeowners looking for both style and function. Modern pillars can complement or replace walls without weakening the home’s overall structure. Like walls, they can also last many decades.
Tips to Choose the Best Exterior Wood Posts
1. Pressure-treated wood
2. Shape (round, octagon, square, rectangular)
3. Weather resistance
4. Weight-bearing capacity
5. Column style
- Basic vertical beams: Conservative or classic porch columns provide clean lines that blend well with matching banisters, railing, and soffit features. We recommend them for homes that already boast plenty of ornamentation.
- Porch column wraps: You can also opt for porch column wraps to change the style or look of an existing porch column. Column wraps are ornamental rather than load-bearing structures. If you need an informative guide about porch column wraps, there are valuable resources online that can give you insights.
- Buttress-style porch posts: They offer a great way to extend design elements to the exterior wood posts. Additionally, the posts create a powerful visual effect while adding a layer of structural support to the home.
- Multi-level exterior wood posts: For double-decker porches, multi-level porch posts create quite a visual impact. Elongating the beams makes the building appear slightly taller and cleaner.
- Others: Other exterior column styles to consider are twin column porch posts, stately design exterior wood posts, Victorian porch posts, and colonial wood post front porch style.
6. Environmental Considerations
When selecting wood for exterior columns, it’s crucial to consider the environmental impact of your choice. The sustainability of different wood types varies significantly, with some having a much smaller carbon footprint than others.
For instance, choosing woods sourced from sustainably managed forests ensures a lower environmental impact and supports responsible forestry practices. Such selection aids in conserving biodiversity, combating climate change, and providing a more sustainable option for sourcing wood.
Additionally, some woods naturally have a smaller carbon footprint due to their growing conditions and processing methods. Opting for these choices can contribute to a more environmentally friendly construction process. Researching and selecting woods that align with these environmental considerations is beneficial, ensuring your porch columns are aesthetically pleasing and environmentally responsible.

2. Red or white oak
Oak is another excellent wood type for exterior porch columns. Indeed, it’s one of the most popular woods for exterior columns. Homeowners and contractors love its dimensional stability and durability.
If you’re wondering what dimensional stability means, it’s the quality of structures to retain their shape and size even under harsh conditions such as extreme weather.
Red and white oak are the best choices. White oak has a Janka rating of 1260, while red oak is even harder at 1360 Janka. Both also boast high aesthetic value and are easily workable.

- Tend to darken over time
You’ve likely heard a few things about mahogany. It’s one of the most in-demand hardwoods, even for making epoxy tables and exterior columns.
Although it’s commonly used in round columns, mahogany also works excellently for octagonal, rectangular, and square columns. Besides its extreme strength (800 Janka), mahogany stands out for excellent water resistance.
It repels moisture and water than most wood types on this list, allowing it to perform well in wet climates.
Above all, the reddish-brown tone adds a classical look to any exterior. However, you can paint it if you wish.

For one, it’s one of America’s most durable woods. It can last many decades or even centuries with proper maintenance. However, the open-cell structure of cedar makes it less dense thus lightweight than most softwoods.
The low density also makes it easy to work (cut, saw, nail, etc.). The even grain and relatively consistent density make cedar columns less likely to swell, warp, cup, or twist even in extreme weather conditions.
- Exceptional dimensional stability
- Extremely resistant to decay
- Has thermal and insulating properties
- Best shou sugi ban wood
- Good finishing and workability characteristics

How to Prevent Wood Porch Columns from Rotting
A common challenge you may experience after installing wooden columns is rotting. This happens even in treated wood columns.
How does this happen? It mostly has to do with weather and the natural tendency for lumber to behave like a live tree. Wood naturally absorbs water from the ground and, through osmosis, transfers the moisture upward, cell by cell, to the top.
This goes on throughout the life of the shaft, often resulting in rotting. Different types of wood rot at different rates.
Signs of Rotting in Wooden Columns
The following are the main warning signs of rotting in wooden columns to keep an eye out for during regular inspections;

Tips for Longer Lasting Exterior Wooden Columns
Fortunately, you can take steps to slow down or prevent wooden columns for porch from rotting in the first place. Consider the following tips;
- Choose rot-resistant woods: The first step is to find rot-resistant wood columns for porch that naturally repel water and moisture. Maple, Mahogany, and Redwood are some of the best options. They also make the best wood axe handles.
- Prime and paint the shafts: Painted columns are highly moisture resistant. Begin with a coat of primer, then add three coats of paint. Alternatively, you can stain your columns.
- Don’t drill holes at the bottom of the shafts: Holes at the bottom of the column tend to provide a conduit for water to migrate up the shaft. Instead, use a solid base with ventilation slots and install the column upon the base.
- Select the right base: Aluminum plinths do a great job, as do synthetic bases. The idea is to ensure free airflow under the column to slow down moisture uptake.
