How Long Can Wood Framing Be Exposed To Weather?

BY |

Wood framing is a preferred choice for construction for the majority of people. Although it may have its downsides, it is considered much more effective than the other choices.

Whether you’re thinking of building a place of residence, or workplace you most probably have considered wood framing, but do you know how long wood framing can withstand weather?

Allowing your wood framing to be exposed to the weather for more than a year or two is not recommended. The majority of wood used to construct houses and other structures has, however, been treated to withstand the elements.

Weather, sun, wind, and rain should all be avoided when building a wood frame. If the wood has been exposed for more than a year, it should not be used for construction.

Wood rot will also occur sooner if the wood is not allowed to completely dry out in between rain or snowstorms, even if it has only been exposed for a few days or weeks. Continue reading to learn more about how to work with damp wood.

Moisture’s Impact On Timber Framing


The ideal case scenario for reducing the impact of moisture would be to cover the frame for an extended amount of time left exposed or to attain partial lock-up to assure the weatherproofing of the structure, but this is not always practicable or feasible.

The last thing you want to be doing is returning to inspect and alter tarps regularly.

When does it become necessary to examine the moisture impact of a timber-framed structure after it has been exposed to the elements for an extended period or after extreme weather events?

There isn’t a straightforward answer to this. Each site would need to be examined for the possibility of timber component degradation, with any necessary changes made.

Time of exposure, structural protection, amount of wet days, the time allowed for lumber to dry, and climate temperature are all aspects to consider when building a wood structure.

When a partially built structure is exposed to the elements, the factors listed above impact the pace of decay, some lumber may need to be replaced after a few months of exposure, while others may be safe for use after a year.

When wood has a moisture content of 20% or more for an extended length of time, fungal decay or decay can occur, especially in untreated wood. Mold, on the other hand, is just visible on the surface and does not affect the underlying wood.

Importance of Choosing High-Quality Wood Framing

Since timber is a natural commodity, its quality varies depending on the species and even the individual tree. It’s critical to use high-quality timber boards that are sturdy, straight, and long-lasting in your home construction.

The cornerstone of most of your home’s construction is good framing, and it has an impact on the result. If your home’s internal walls aren’t straight because of uneven framing, you’ll have to spend additional money to get the sheathing right and float the drywall.

Exterior siding, baseboards and crown moldings, tiles, and even flooring might be affected. Framing is essentially a foundation. So, get it right and truthful, and everything else will fall into place.

It’s tough to join corners properly when framing is crooked or of poor quality. Even if you hire a skilled carpenter, there’s only so much they can accomplish. This means that work will take longer and will almost always be of lesser quality, jeopardizing structural integrity.

It also has an impact on the services provided by your home. Electricians and plumbers must pass through your timber structure to provide their services. This job is more complex and time-consuming because of the crooked framing.

It may even necessitate cutting through your framework for pipes to fit properly. The Building Code regulates how much of a frame can be cut out, which may need you to change portions of your frame to accommodate it.

Can You Build Using Wet Wood?

Wet wood should be no trouble to build with. It’s simply more difficult because the wood is slick and difficult to cut. When it’s raining, you shouldn’t use power tools since that’s where the danger begins.

Allow the wood to cure completely before using it. Shrinkage, cracks, gaps, squeaks, and rot may occur if not properly maintained. These impacts do not occur instantly but rather over time as a result of extended exposure to wet circumstances.

As a result, building with wet wood leads to problems later.

It is critical to have dry wood for your construction operations. If it’s impossible to avoid moist wood, there are a few things you can do at home to try to keep it dry.

Why Is Wood Framing So Popular?

It Is Natural

Timber is one of the oldest natural building materials on the planet. It holds up well over time, is non-toxic, does not emit volatile organic chemicals, and is easy to deal with.


Other materials, such as concrete and steel, require more credentials and technical knowledge. It also does not necessitate welding or other specialized processes, which can extend a project’s duration and cost.

Finally, as wood ages, it is simple to maintain and repair, and it may be exposed and treated, making it a visually appealing structural system.

Environmental Friendly

The timber frame derived from sustainable forests is extremely environmentally friendly. Most timber suppliers have regulations in place that require them to plant more trees than are felled for construction.

You can alternatively buy it locally, avoiding the carbon footprint of long-distance shipping.

Improved Insulation

When compared to other framing materials, wood has a higher thermal resistivity. For both the building and the client after completion, wood framing is more energy efficient. This is due to wood’s cellular structure, which contains air pockets by nature.


Timber is a versatile material that can be produced to fit any type of home design or architectural style. Regardless of the architectural style or feature you need for your home, timber can provide it safely, dependably, and at a low cost.

Is OSB Framing Waterproof?

You’ll be relieved to learn that the OSB frame is water-resistant. Manufacturers do this because they know it’s impossible to finish a house without water or snow getting inside at least once.

Wood can withstand being submerged in freshwater for hundreds of years with no ill effects.

To avoid damage to your OSB boards, make sure the surface is clean and free of debris. Water can be held against the boards by debris. After each storm, you want any standing water to be washed away as quickly as possible.

What Should You Do To Handle Wood Rot?

Rot is a bacteria that survives by consuming water. When you expose a damp wall, you’re more likely to locate studs and wall plates, which is a good indicator of degradation.

Heat, air circulation, and a dehumidifier are the most effective ways to kill wood rot. It is, however, only conceivable if the wood can still be saved.

In some situations, the rot has completely devoured the majority of the wood. As a result, killing those germs before they affect the core of your lumber is critical.

In addition to heat, you can use a borate wood treatment powder to eliminate the rot fungus. Dig out the rot once it has dried.
