Winter Is Coming: Ensure Your Masonry’s Survival with Expert Cold and Snow Preparation!

Masonry's Survival with Expert Cold

As the leaves change colors and the air turns crisp, there’s no denying that winter is right around the corner. While the season brings the magic of snowfall and cozy evenings by the fire, it also brings its own set of challenges, especially for masonry structures. 

The cold, snow, and freezing temperatures can take a toll on your masonry, causing damage that ranges from minor issues to significant structural concerns. To ensure your masonry’s survival and longevity, it’s crucial to prepare your building for the impending winter weather. In this comprehensive guide, we’ll walk you through expert tips on how to safeguard your masonry against the harsh elements of winter.

Understanding the Impact of Winter on Masonry

Before we delve into winter preparation, it’s essential to understand how winter weather can affect masonry structures. Masonry includes materials like bricks, stones, and concrete, which are susceptible to damage caused by the cold and snow. Some common issues that can arise during winter include:

  • Freeze-Thaw Cycle Damage: This occurs when moisture infiltrates masonry and then freezes, causing the expansion of water molecules. As water expands when it freezes, it exerts pressure on the masonry, leading to cracks and fractures.
  • Efflorescence: Efflorescence is the white, powdery residue that forms on the surface of masonry. It’s caused by water seeping into the masonry and carrying minerals to the surface. When the water evaporates, it leaves behind these minerals, resulting in unsightly marks on the masonry.
  • Spalling: Spalling is the chipping or flaking of masonry surfaces. It can be caused by the expansion of water within the masonry, and the subsequent freezing and thawing process.
  • Cracking: Cold temperatures can cause masonry materials to contract, leading to the development of cracks. These cracks can compromise the integrity of the structure.

Now that you’re aware of the potential issues, let’s explore the steps you can take to protect your masonry during the winter months.

  1. Inspection is Key

The first step in winter masonry preparation is a thorough inspection. This includes examining the entire masonry structure for any existing damage, cracks, or areas of concern. Pay special attention to areas that have previously shown signs of wear and tear. By identifying and addressing issues now, you can prevent them from worsening during the winter.

  1. Repair and Repoint

If your inspection reveals any damage or deteriorating mortar joints, it’s essential to address these issues promptly. Repointing is a process that involves removing deteriorated mortar and replacing it with new mortar. It not only restores the structural integrity but also enhances the overall appearance of the masonry.

  1. Clean the Masonry

Before winter arrives, it’s a good idea to clean your masonry to remove dirt, debris, and any efflorescence that may have formed. Cleaning can be done through pressure washing or with appropriate cleaning solutions. Clean masonry is more resistant to winter damage.

  1. Waterproofing for Protection

To shield your masonry from the freeze-thaw cycle and moisture infiltration, consider applying a waterproofing sealer. This protective coating forms a barrier on the masonry’s surface, preventing water from seeping in and causing damage. It’s particularly important for vulnerable areas, such as chimneys and foundation walls.

  1. Insulate and Weatherstrip

Proper insulation is not only essential for keeping your home warm but also for protecting your masonry. Insulate your home’s walls and attic to prevent temperature fluctuations that can affect the masonry. Additionally, check and replace weatherstripping around doors and windows to keep cold air out and warm air in.

  1. Gutter and Downspout Maintenance

Clean your gutters and downspouts before winter to ensure proper drainage of rain and melting snow. Clogged gutters can lead to water overflow, which can then penetrate masonry and cause damage. Also, consider extending downspouts away from your foundation to prevent water from pooling near the base of your masonry structure.

  1. Landscape Considerations

Trim back trees and branches that could potentially fall on your masonry during winter storms. Falling debris can cause severe damage, so it’s best to prevent this from happening in the first place.

  1. Snow Removal Strategy

Have a snow removal plan in place. Excessive snow accumulation on your masonry can be heavy and cause stress on the structure. If you’re not equipped to handle snow removal yourself, hire a professional service to clear snow from walkways, driveways, and the roof if needed.

  1. Interior Preparations

To keep your masonry warm and minimize the risk of freeze-thaw damage, ensure that your home’s interior is adequately heated and well-insulated. Monitor the temperature and consider using space heaters in areas with vulnerable masonry, such as basements.

  1. Professional Consultation

If you’re unsure about the condition of your masonry or the necessary repairs and preparations, it’s always a wise idea to consult a professional mason. They can provide expert guidance, conduct necessary repairs, and offer insights specific to your masonry structure’s needs.


Winter is a challenging time for masonry, but with the right preparations and maintenance, you can ensure the survival and longevity of your building. By inspecting, repairing, and protecting your masonry, you’ll not only prevent damage but also enhance its appearance and structural integrity. Don’t wait until the first snowfall to take action. Start your winter masonry preparations now to enjoy a cozy, safe, and beautiful space throughout the colder months.
