Window maintenance is a challenge for many commercial property managers. A property may have dozens or even hundreds of individual windows; inspecting each one on a regular basis can be time-consuming. Yet, proper maintenance is critical. Minor problems, like a window leak, for example, can quickly develop into major issues. If not caught early, a window leak can cause costly damage, and may even require the entire window and surrounding envelope components to be replaced. For commercial properties, these replacement and repair costs can quickly add up.

Fortunately, preventative maintenance and regular inspections can help prevent window leaks from developing into full-scale problems. In fact, finding leaking windows early can help save property owners money in a number of ways. Here are five reasons to you should regularly inspect your windows for leaks:

1.   Ineffective Insulation

Leaks diminish the window’s insulating value, which is one of the most common reasons for uneven heating and cooling. During winter months, for example, a window leak would draw warm air from the interior, which would contribute to a higher peak heating loads to increase. In other words, leaky windows can directly affect your property’s efficiency.

2.    Water Damage

New windows that are properly installed can last 20 years or more. Yet, without proper maintenance, systems fail much faster, particularly if water is leaking into the window’s frame. Water leaks, which are caused by improper or damaged window seals, speed up the deterioration of the windows components and cause corrosion. Prolonged water damage causes a window to fail much faster.  

3.    Mold

Water damage causes a host of issues, beyond damage to the window’s framing and components. Mold is another direct result of prolonged window leaks. Essentially, water seeps into the building envelope, and over time causes the building’s materials to decay and mold. Repairing mold damage can be very costly, in some cases, requiring areas of the building envelope to be rebuilt.  

4.    Occupant Complaints

Bad leaks cause noticeable drafts of cool or hot air. If your building has problems with drafty windows, chances are you will experience an uptick in comfort complaints from occupants. Repairing window seals can help to diminish this effect.

5.   Foggy Glass

Your windows can fog for a number of reasons. But if they’re older windows, chances are the seals have failed. When a seal has been compromised, moist air seeps in between panes. As a result, this moisture collects on the window creating visible fog.

Risks Associated With Leaky Windows

While a small window leak may not seem like a big deal, over time, it can cause serious problems. The following are some of the risks associated with unrepaired window leaks:

• Energy Waste: Leaky windows can allow air to escape from your building, causing your HVAC system to work harder to maintain a comfortable temperature. This can lead to higher energy bills and increased carbon emissions.
• Reduced Comfort: Leaky windows can create drafts and hot or cold spots, making it difficult to maintain a consistent temperature and reducing overall comfort levels.
• Water Damage: Leaky windows can allow water to seep into your building, potentially causing structural damage, mold growth, and other water-related issues. This can be especially problematic in areas with heavy rainfall or high humidity.
• Health Risks: Water damage and mold growth can lead to health risks such as respiratory issues, allergies, and other illnesses. Additionally, leaks can create a damp and humid environment, which can promote the growth of bacteria and viruses.
• Decreased Property Value: Leaky windows can detract from the overall value and appeal of your building, making it less attractive to potential buyers or tenants.
• Reduced Indoor Air Quality: Leaky windows can allow outdoor pollutants and allergens to enter your building, reducing indoor air quality and potentially causing health issues.
• Pest Infestations: Leaky windows can provide an entry point for pests such as insects and rodents, which can cause property damage and health hazards.
• Aesthetics: Leaky windows can create unsightly water stains or damage, which can detract from the overall appearance of your building and harm its curb appeal.
• Compliance Issues: In some cases, leaky windows may not meet local building codes or regulations, which can result in fines or legal action.

What’s the Solution for Leaky Windows?

Window leaks are most commonly caused by failing or damaged seals, weather stripping or caulking. The good news: Resealing windows is a cost-effective solution that will prevent long-term damage.

In fact, repairing a window’s seal will restore its performance and efficiency. If no components have been damaged, the window will perform like it did the day it was installed.
