How to Winterize Brick and Stone to Avoid Costly Damage
Central Pennsylvania winters are tough on homes. Between freezing temperatures, heavy snow, and the constant cycle of freezing and thawing, brick and stone can take a real beating. Left unprotected, masonry surfaces can crack, crumble, or even fail completely. The good news? A little winter preparation now can save you from costly repairs in the spring. Here’s how to winterize your brick and stone so your home stays strong and beautiful all season long.
Why Masonry Needs Protection in Winter
Brick and stone may look solid and permanent, but they’re porous materials that absorb water. When temperatures drop below freezing, that water expands, creating cracks that only worsen over time. This freeze-thaw cycle is one of the leading causes of spalling bricks, failing mortar joints, and deteriorating stonework. Winterizing your masonry is about prevention—keeping moisture out and ensuring your structures can handle the weather ahead.
Inspect for Existing Damage
Before you can protect your masonry, you need to know its current condition. Walk around your home and look for crumbling mortar, loose bricks, flaking stone surfaces, or white streaks (efflorescence) that indicate water intrusion. Don’t forget to check chimneys, walkways, retaining walls, and steps—any exposed masonry is vulnerable. If you spot damage, it’s best to schedule professional repairs before freezing temperatures set in.
Repointing and Repair Work
One of the best ways to prepare brick and stone for winter is repointing—the process of replacing deteriorated mortar between joints. Fresh, properly mixed mortar prevents water from sneaking behind the bricks where it can freeze and expand. In some cases, damaged bricks or stones may need to be replaced entirely. Taking care of these repairs in the fall ensures your masonry will hold up when snow and ice arrive.
Waterproofing Treatments
For added protection, many homeowners opt for breathable masonry sealants. These treatments repel water while still allowing moisture vapor to escape, preventing trapped moisture that can cause even bigger issues. A professional application ensures even coverage and long-lasting results. Not every structure needs waterproofing, but it can be a smart investment for chimneys, retaining walls, or any masonry in direct contact with the elements.
Clean and Clear Surrounding Areas
Winterizing also means paying attention to what’s around your masonry. Clear leaves, mulch, and debris away from the base of walls and steps, since trapped moisture can seep in. Make sure gutters and downspouts are directing water away from your home. Even something as simple as trimming back shrubs can improve airflow and help keep masonry dry.
Prepare Walkways and Steps
Walkways, patios, and steps face heavy use in the winter months. Salt and harsh ice-melts can damage masonry surfaces, causing pitting and discoloration. Stock up on masonry-safe de-icing products and use sand for traction when possible. Taking a little care with what you use on your surfaces goes a long way toward protecting your investment.
A Little Prevention Goes a Long Way
Winter can be unforgiving, but your brick and stone don’t have to suffer the consequences. By inspecting, repairing, sealing, and preparing your masonry now, you’ll avoid costly damage and extend the life of your home’s most durable features.
