Windows offer us ventilation and a view of the outside world–which is beautiful here around Tampa Bay! However, old windows can cause significant problems such as water leakage. If your windows are leaking water, there are several culprits to blame. 

This issue often stems from two main causes: installation oversights and the natural wear and tear of window components. 

Poor installation can result in gaps that allow rainwater to seep in, turning a light spring shower into a costly repair job. But how can you locate where the moisture is entering?

Common Entry Points for Moisture

The usual suspects for water leakage include the window frame, the sill, and the point where the glass meets the frame. But realize that a leak doesn’t always point to a flaw in the window itself. In some cases, the problem stems from structural issues in the home’s design, like an improperly angled fascia board above the window.

Windows Leaking Water? Try Some Basic Maintenance Tips

If your windows are leaking water, don’t panic. Sometimes the problem can be resolved through basic maintenance. 

Routinely Check Your Windows for Leaks

If you worry about windows leaking water, it’s time to do a check on your windows. Regularly inspect your windows for any signs of wear and tear, such as cracks or gaps. Check the sealant, weatherstripping, and the overall condition of the window frame and sash.

Upgrading Weatherstripping and Caulking Upgrades

Replacing weatherstripping or caulking, especially with silicone caulking, can effectively prevent further moisture damage. Caulking is a type of sealant that is used to fill gaps and cracks in walls and other surfaces. It can be made from a variety of materials, including silicone, acrylic, and latex.

The best caulking for stopping water leaks in windows? Silicone. Silicone caulking is a waterproof option that withstands rainwater, making it an excellent choice for these repairs.

Meanwhile, weatherstripping is a type of material that is used to seal gaps around doors and windows. You can find it in a variety of materials, including rubber, vinyl, and foam. 

Regular inspections of weatherstripping, caulking, and window locks are key to preventing moisture damage. Even something as minor as an unlocked window can lead to moisture ingress. These routine checks ensure that everything is functioning correctly and securely. If you aren’t sure where to start, please call us at Storm Pro Window & Door!

Why Worry About Windows Leaking Water?

Ignoring leaky windows can lead to a myriad of expensive problems, and here’s why. When moisture seeps into a home, mold can quickly begin to grow. This is especially true when moisture accumulates in a warm, dark environment. 

Mold from leaky windows can make you feel . . . 

  • Exposure to mold can cause coughing, wheezing, and throat irritation.
  • Mold spores can trigger allergic reactions like sneezing and itching.
  • In asthmatic individuals, mold can worsen symptoms and trigger attacks.
  • People with weakened immune systems may experience more severe reactions.
  • Direct contact with mold can lead to skin rashes and irritation.
  • Exposure to toxic molds can cause headaches, dizziness, and memory loss.
  • Living with mold can increase stress, anxiety, and depression.

Windows Leaking Water Can Cause Severe Moisture Damage

In more extreme cases, water damage can affect the internal wall, potentially leading to wood rot if not addressed promptly. 

There are mainly two types of wood rot: dry rot and wet rot. Dry rot is more severe and can spread across wood surfaces, even those not directly exposed to moisture. Wet rot, while typically more localized, also weakens wood but requires a higher moisture level.

Weakening of Structural Integrity

As the wood rots, it loses its strength and becomes brittle, compromising the structural integrity of the building. This can lead to sagging floors, weakened door frames, deteriorating beams, and compromised roof structures.

Increased Susceptibility to Damage

Homes with significant wood rot are more vulnerable to additional damage, especially during adverse weather conditions. For example, in the event of a storm, weakened structures like roofs and walls are more likely to incur damage from high winds or heavy rains.

Health Risks

Wood rot can also be associated with mold growth, leading to the health risks discussed earlier, such as respiratory issues and allergic reactions.

Costly Repairs

Addressing wood rot often involves not only removing the affected wood but also addressing the source of moisture. This can lead to extensive and costly repairs, especially if the rot has spread over a large area or affected critical structural elements.

Pest Infestations

Rotted wood can attract pests like termites and carpenter ants, which further damage the wood, exacerbating the problem and potentially leading to more extensive infestations.
