Wood is one of the best materials for exterior columns. Not only are exterior wood columns strong and functional, but also practical and beautiful. Above all, it’s much easier to install porch columns than stone or concrete.

The caveat – not all types of wood are good for porch posts. Indeed, some wood types aren’t good enough for exterior wood posts at all. Moreover, wooden exterior columns may rot without proper selection, installation and maintenance.

This guide discusses the following;

  • The benefits of wooden porch columns
  • Exterior wood types for front porch columns
  • Tips to choose the best wood for exterior columns
  • Maintenance hacks for wooden exterior columns.

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 and pillars because they elevate exterior aesthetics. Decorated columns, such as capitals that feature flourishes and accents, significantly improve the property’s outlook.
  • 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

As you’d expect, not all wood types are good for exterior columns. Before we look at some of the best wood types to consider, let’s discuss a few tips to prioritize during selection.

1. Pressure-treated wood

The first thing you should consider is whether the wood is treated or not. Pressure-treated wood columns are typically from yellow pine or Douglas Fir.

The posts are immersed into or injected with chemicals that repel moisture. Moisture-resistance increases rot resistance. Beware, though, that not all pressure-treated lumber make good exterior columns.

That’s because pressure treatment makes some wood types susceptible to warping and splitting, especially if you don’t paint the columns.

For this reason, you must never substitute quality wood for pressure-treated options. Also, be wary of health concerns.

2. Shape (round, octagon, square, rectangular)

Wooden columns come in four broad shapes, i.e., round, octagon, square, and rectangular. Most people prefer round or molded columns. Round columns typically comprise six or more pieces with mitered edges.

The pieces are glued together and molded. Meanwhile, octagonal posts comprise eight pieces molded together at 22.5 degrees. Square and rectangular columns are also common, though not as rounded and octagonal posts.

This is because they are less reliable and cannot hold as much weight as round and octagonal posts – unless you use strong hardwoods.

3. Weather resistance 

Of course, weather resistance is more important in locations with extreme climates. Nevertheless, you still need to find wooden columns that can withstand occasional or prolonged harsh weather conditions.

For instance, cedar, redwood, and cypress repel moisture excellently, thus making great wood columns for front porch even in wet climates. Meanwhile, teak performs best in average to warmer climates.

Additionally, consider whether the area gets a lot of snowing in winter.

Freezing during snowing can test wooden posts to the limit. Prolonged freeze-thaw cycles can stress the posts, eventually causing rotting. Some wooden posts now come in water-resistant coatings to prevent warping during winter.

4. Weight-bearing capacity 

Unfortunately, just because a wooden column looks wider or thicker doesn’t mean it can support the porch. In fact, some of the larger wooden porch columns are hollow inside, meaning that they cannot bear much weight.

For this reason, you should ensure that you’re getting columns that can carry the weight of your porch roof, ceiling, and wall (where applicable).

Most column manufacturers indicate the weight-bearing capacity on the product body. However, don’t hesitate to call the manufacturer to find out or verify this information.

5. Column style 

Finally, wooden columns come in many styles. The following are popular exterior column styles to consider;

  • 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.  
  • 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.

9 Best Wood for Exterior Columns

Now, let’s discuss some of the best wood for exterior columns. We’ve only picked the best nine. However, always feel free to explore other options.

1. Birch

Birch is considered one of the best choices when shopping for stable exterior wood columns. It is a high-density hardwood perfect for round, square, or even rectangular porch columns. Birchwood is also durable.

The straight grains are another reason birch makes an excellent wood for exterior columns. Together with the natural pores and waves, the fine grains add a unique look to wooden columns.

Remember that you can also stain or paint birch wood as you wish. This means you can decorate your birch columns to complement the rest of the porch.

PROS

  • Hard and durable (1260 Janka)
  • The beautiful straight, fine grain pattern
  • Highly workable
  • Resistant to natural decay

CONS

  • Poor water/weather resistance
  • Poor pest resistance



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.

You can paint the columns in the color you want and easily drive screws and nails into them.

PROS

  • Extreme strength (1260-1360 Janka)
  • High dimensional stability
  • Easily workable
  • Fire and wear-resistant

CONS

  • Heavy thus difficult to move
  • Tend to darken over time



3. Mahogany

You’ve likely heard a few things about mahogany. It’s one of the most in-demand hardwoods, even for making 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.  

PROS

  • Highly durable
  • Highly water and rot-resistant
  • Rich reddish-brown tone
  • Holds paint and staining well

CONS

  • Difficult to work
  • Not readily available, thus expensive



4. Douglas Fir

The Douglas Fir is an evergreen conifer species in the pine family. It’s native to western North America, where it’s also common as Douglas spruce or the Oregon pine.

It makes many “best wood type” lists because it’s fairly strong (660 Janka) while being highly affordable. Additionally, Douglas fir has a notable low shrinkage and warp rate.

This means it can withstand harsh weather conditions with little strain. Moreover, it’s highly resistant to insect attacks as well as fungus. The only downside is that it is not as reliable as the stronger hardwoods for holding significant weight for years.

PROS

  • Lightweight, thus easy to move
  • Low shrinkage and warping
  • Great for front porch wood columns
  • Highly resistant to fungus and insect attacks
  • Highly affordable

CONS

  • Discolors over time
  • Difficult to work with hand tools



5. Cedar Column

Cedar, also common as the Western Red Cedar, is a beautiful, durable, versatile, and easy-to-maintain wood with plenty of qualities that make it excellent for exterior columns or even cedar-wrapped posts. The latter involves wrapping posts in cedar.

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.

PROS

  • Exceptional dimensional stability
  • Extremely resistant to decay
  • Has thermal and insulating properties
  • Good finishing and workability characteristics

CONS

  • Relatively low strength (900)
  • Requires significant maintenance



6. Maple

Maple wood comes in many species and it’s one of the best wood for porch columns. However, the hard maple, aka sugar maple, is the best choice for exterior porch columns.

It’s white wood with reddish-brown hues, though the color tends to deepen with age.

Meanwhile, the heartwood is brownish-red and sometimes quite dark. The two standout advantages of maple over other wood types are cost and strength.

Maple is rated 1450 on the Janka hardness scale, making it one of the strongest woods. Interestingly, it’s also one of the cheapest hardwoods and the best wood for indoor furniture such as tabletops.

These two qualities have endeared many woodworkers to maple.

PROS

  • One of the hardest hardwoods
  • The cheapest wood to buy
  • Extremely durable and strong
  • Highly moisture-resistant
  • Resists shrinking and warping

CONS

  • Poor weather resistance
  • Prone to insect damage



7. Cherry

Cherry can be the best wood for porch posts depending on your needs. Many people avoid it because it’s too expensive for lumber that scratches so easily.

However, cherry boasts unique characteristics that can drastically transform your front porch and home in general.

For one, cherry is a deciduous wood with a fine, straight grain ranging from reddish brown to blond.

This gives it a striking sight from afar. The heartwood is also reddish-brown but has a golden hue that transforms into a popular rich-brown over time.

More importantly, it’s highly flexible and easy to work due to its straight-grained qualities. It also possesses good bending qualities and low stiffness. Cherry is rated 950 Janka.

PROS

  • Good finishing properties
  • Highly workable making them a good fit for front porch wood columns.
  • Beautiful fine, straight grains
  • Highly flexible, thus customizable

CONS

  • Relatively expensive
  • Scratches and dents easily



8. Redwood

Redwood is a premium building wood characterized by a chemical inside the pores that makes it weather, insect, and rot-resistant.

Therefore, it lasts far longer when exposed to the open air than many other wood types.

This makes it perfect for making exterior porch columns, though it can also be used inside the house. However, the main advantage of redwood is strength.

At 3190 Janka, it’s the hardest wood you can go for when shopping for exterior columns for your front porch. The high strength means it resists warping and splitting with ease.

Surprisingly, it’s much lighter than its peers, making it easy to saw, cut, and drill.

PROS

  • Rated excellent for building and outdoor structures
  • Exceptional strength and durability
  • Highly weather and rot-resistant
  • Wide range of applications

CONS

  • Scratches easily
  • Very expensive



9. Yellow pine

Finally, yellow pine is another excellent choice, especially if you’re more interested in style than strength. It’s one of the most readily available lumbers. So, you can pick up the pine of your choice at the local lumber yard.

Moreover, pine is easy to work with and has a pleasant yellow tone that instantly adds warmth to the house. However, many woodworking experts don’t recommend pine for exterior applications due to its durability.

Pine also requires regular maintenance, especially when exposed to the open air. Nevertheless, it’s an affordable option with excellent workability and finishing qualities.

PROS

  • Reasonably strong at 1570 Janka
  • Highly workable and excellent finishing
  • Highly available
  • Very affordable

CONS

  • Not very durable
  • Requires regular maintenance



Why Choose Wooden Porch Columns?

Different front porch columns come in different materials. For instance, traditional columns are made from stone or brick. Both materials are readily available and highly customizable.

Similarly, many people love fiberglass columns as fiberglass is highly resistant to insects and rot. The only downside is that fiberglass columns aren’t very aesthetically pleasing.

Metal columns, primarily aluminum and iron pillars, are also common due to the durability and customizability of the two materials.

However, most homeowners and constructors prefer wooden columns over other materials today. Here’s why;

Natural beauty

Modern front porch columns are naturally beautiful. In fact, if you’re looking for a truly classic look, you cannot do much better than wood.

For instance, you opt for the shiny yellow tone of birch or grain patterns of mahogany.

The choice is yours. Better still, you can stain or paint the wooden columns to fit your décor. Wood also adds visual warmth and brings class and elegance to dress up the porch.

Little deterioration from heat

Unfortunately, stone, brick, and even metals cannot withstand the extreme expansion and contraction in hot climates.

For instance, constant movement in the mortar between bricks weakens the joints, impacting the strength of the pillar and reducing the life of the structure.

Wooden pillars for porch may have many issues, but heat isn’t one of them. This makes them the perfect choice for warm climates.

Help with sound absorption 

If you intend to throw outdoor parties or splash around in the pool with family and friends occasionally, modern front porch columns can help absorb the resulting sounds for minimal disturbance.

Why? Because wood absorbs sounds excellently. It’s why reason you’ll often find wooden pieces throughout your local concert hall.

Other practical advantages 

Other benefits of wood over other exterior column materials include increased insulation from heat, increased balance in humidity, and green living.

If you’re wondering how wooden pillars for porch enhance balance in humidity, wood absorbs excess moisture when it’s too humid around your home, thus leaving your home sufficiently dry.

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;

  • Mold and algae growth
  • Cracks in the wood
  • A sunken column base
  • Separation of staves

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.
  • 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.

1 thought on “Top 9 Best Wood for Exterior Columns & Porch Posts”

  1. Great article, however you failed to mention white pine as a quality wood for building exterior columns and porch posts.
    Some of the woods you mentioned are good but very rarely used because of cost and difficulty in working the material.
    Accoya, the absolute best, is a genetically engineered pine and guaranteed not to rot for 50 years ( untreated ). Spanish Cedar is also an excellent alternative with its natural resins that resistant rot and bug infestation. Clear white pine when primed and painted will last out side your home for generations. The ends of all exterior wood must also be sealed so that moisture cannot wick into the end grain.
    As a supplier of exterior turned porch posts and columns to the North American market we have been using clear white pine with great success for over 20 years.
