It’s inevitable for wooden windows not to get affected by external elements, most especially the rain. As the wood absorbs water, it expands and then contracts as it dries out. Although some types of wood are more vulnerable than others, they could still use preventive and protective measures for their longevity and durability.
In extreme and fluctuating temperatures, poorly installed and poorly maintained windows contract and expand. This creates little gaps wherein moisture can settle in and cause rot. Over time, you’ll find your windows in a weird shape and looking expensive to repair.
Your window screens might still be intact, but you’re still going to need some protection from extreme weather changes. This doesn’t just affect their ability to insulate properly, as they also affect the value of a home.
Fortunately, there are ways to prevent this from happening. Get on top of it by knowing why and how windows warp and rot.
What Causes Windows to Warp?
The unevenly absorbed moisture causes stress within the wood. As a result, a window becomes deformed. The moisture causes the wood to shrink and expand, ultimately affecting its quality and functionality. Wood as a material naturally retains moisture. But when it does it too many times for a long period, moisture does what it does. Additionally, it can even cause mold and rot on the wood.
Although there are other factors such as direct sunlight, temperature, and the type of grain, moisture is the most contributing factor to warping.
What Causes Windows to Rot?
Moisture plays a huge role in the development of rot. However, rot isn’t noticed right away until it’s too late. When moisture is absorbed into the grain of the wood, fungi start to grow in the wood tissue. Although it’s hard to know when the rot has started to grow, you can use a hard object to prod on the surface gently. If any area gives in, that can be a sign of rot.
Excess oxygen, acidity, extreme temperature changes, direct sunlight, urine, and manure, are other factors that contribute to fungal growth.
Why You Should Take Care of the Windows
Just like any other part of your home, the windows need regular maintenance too. Besides their basic function to protect its interior from external elements, they contribute to your home’s energy efficiency. Any gaps can affect both your utility bills and the performance of both heating and cooling systems. Additionally, neglecting the windows will only mean costly repairs in the future if they continue to be unmaintained. Not to mention, there’s the curb appeal and overall value of your home to think about.
How To Prevent Wood From Warping
Choose the Right Kind of Wood
Warping is less likely for wood with very straight grain patterns, regardless of wood species. The grain should be packed together with less than 1/31 inch between grain lines. The straighter and closer grain lines are, the more durable they can be as windows.
Redwood, cedar, and fir are among the best wood species to withstand weather changes, direct sun exposure, and moisture. But of the three, redwood is best for its grain pattern and moisture-fighting properties.
Seal Cracks, Gaps, and Holes
Any infiltration could have dire consequences for your windows since these are hidden places wherein rot can thrive. In addition, windows will be leaky, causing rainwater to enter the home. Broken caulking and cracked glazing contribute to leaky windows too. Consider reglazing and recaulking for any issues like this and give your windows second life.
Replace the Damp Area
When rot has infiltrated the tissue of wood, it’s best to take this portion of the window out before it spreads. With a tool or anything solid, prod the surface for any signs of decay. If a surface gives in, that’s a sign of rot. If the wood gives in to the light pressure, it’s time for it to be replaced.
Reseal and Repaint
For extra protection and longer use, apply latex paint followed by waterproof wood sealant onto both the external and internal parts of the windows. These should help windows become more resilient in rainy weather. Before grabbing your paintbrush, be sure to sand the windows before applying latex paint. This helps even out bumps and achieve a smooth finish.
All of these interventions need patience and time to achieve. But when done right, the results will pay off. A fixed window means better insulation, saving on utility bills, better performance from heat and cooling systems, and overall enhanced comfort.
