Should I be Worried About Cracks Around My Windows?

It’s quite natural for you to feel concerned when you notice cracks forming around your windows. After all, they can be signs of underlying issues that can not only impact functionality but also compromise energy efficiency and security. But not all window cracks are a cause for immediate alarm.

Should I be Worried About Cracks Around My Windows?

As you read through this article, you’ll discover the common causes of cracks around windows and whether or not you should be worried about them. We’ll also tell you about the potential actions and preventive measures you can take to protect your home and ensure the longevity of your windows.

Why Are There Cracks Around My Windows?

Cracks happen for a variety of reasons. Foundation settlement is one of the most common reasons behind cracks around windows. As older homes settle over time, it causes stress on the walls and windows. This leads to window and wall cracks. Settlement isn’t always caused by poor construction but also due to soil conditions and natural shifting in the ground.

Apart from foundation shifting, other things that can cause cracks around windows include:

• Temperature fluctuations
• Moisture damage
• Improper installation
• Structural movement

Identify the Cracks in Windows

Different cracks have different levels of severity. The most common types of cracks include hairline cracks, diagonal cracks, and vertical cracks. They are caused by different things.

It’s important to first identify the crack to determine if further investigation or repair is necessary.

• Hairline cracks are small and thin cracks that usually occur due to the age and settling of the building. These small cracks are mostly cosmetic and not a cause for concern.
• Diagonal cracks can be caused by structural movement or stress. They might indicate foundation issues or soil movement. You should monitor these and consult an expert if signs of structural movement worsen.
• Vertical cracks are often caused by thermal expansion and contraction. Other agents such as changes in humidity can also cause these types of cracks. Though they are less severe, they should not be ignored, especially because fixing them is very easy. Just fill cracks with caulk or sealant.

Common Causes & Fixes

Foundation settlement, temperature fluctuations, moisture damage, and improper installation are a few of the most common causes of window cracks. Mitigating these causes can be as easy as applying a sealant or a little complex like improving the room’s ventilation.

• Cracks due to foundation settlement can be fixed by underpinning or mud jacking to stabilize the structure and prevent further movement.
• Proper insulation and weatherstripping around windows minimize cracks due to temperature fluctuations.
• Proper drainage and sealing gaps can help you fight against moisture damage leading to window cracks.
• Repairs or replacement might be necessary if the cracks are due to improper installation.

Check Structural Integrity

Cracks around windows can be an indicator of structural damage that might need attention. Sagging window sills and misaligned frames are a couple of the most prominent issues that can lead to permanent structural damage if not repaired promptly. These issues often call for a professional assessment.

• If window sill cracks are surrounded by sagging or misalignment, then it’s a structural issue that requires professional attention.
• Gaps or drafts can also cause cracks around windows and are structural in nature. A thorough inspection will often reveal any air leakage. Seal any such problem with a suitable sealant.

Energy Efficiency

Cracks around windows will often compromise the overall energy efficiency of your home. These can lead to air leakage and more importantly, hamper the insulation between the interior and exterior of the house.

Maintaining an energy-efficient home is very important. Addressing the cracks in the wall under and around windows can help improve the energy efficiency of your home.

• Use a candle or incense stick to detect drafts around windows. If you spot air leakage, then this is going to affect your home’s energy efficiency. Depending on the type of crack, contact a window repair expert to restore your windows or consider window replacement.
• Window insulation is often a great way to improve energy efficiency. Double-pane windows are significantly better than single-pane ones and can reduce energy costs remarkably.

Window Cracks: When to Worry

Some cracks are purely cosmetic and a sign of nothing and then some cracks put the structural integrity of your home in question, often compromising the safety of the house.

It is important that you look at cracks on a case-by-case basis while understanding how different types of window cracks happen so you can solve any underlying issues.
