Winterize and Protect Brick Patios and Outdoor Masonry in Historic DC

The bluster and bone-chilling cold of winter are rapidly approaching, so it's natural that your focus may be shifting to keeping indoor spaces warm, cozy, and extra-inviting. If you live in a historic D.C. home, though, your outdoor spaces need just as much preparation. Brick patios, garden walls, and walkways are some of the most vulnerable parts of an older property. The good news is that taking a few simple steps now can protect them from freeze-thaw cycles and winter storms while preserving their character for years to come.

Prepare Your Historic Brick Patio Before the First Freeze

Older brick in neighborhoods like Capitol Hill or Georgetown absorbs moisture easily. When temperatures drop, this moisture expands at night and contracts during the day, which can widen cracks, loosen mortar, and shift patio bricks.

Before winter, take a moment to inspect your property for loose pavers, gaps between bricks, or areas where water collects. Sweep away leaves and debris that trap moisture in order to discourage moss growth. Aim to start the season with a clean, stable patio that drains well and stays dry.

How Winter Affects Patios and Outdoor Masonry in D.C.

Winter weather can damage historic brick as moisture seeps in and freezes, weakening lime-based mortar and causing spalling. Uneven settling may occur on walkways and patios due to frost affecting the ground. Early preparation helps prevent small issues from becoming structural problems. 

Best Practices for Preparing a Brick Patio Before Winter 

A little maintenance now goes a long way. Before the first freeze:

• Sweep leaves and debris regularly.
• Clean the patio with a soft-bristle broom and a mild masonry-safe detergent.
• Clear drainage paths around downspouts and garden edges.
• Look for efflorescence, loose bricks, or soft mortar.
• Remove any heavy items sitting directly on vulnerable brick.

Avoid pressure washing, which strips away the protective surface of historic brick and accelerates moisture damage.

Should You Cover Your Brick Patio for the Winter?

Covering a brick patio with breathable canvas or treated outdoor fabrics protects it from snow and ice while allowing airflow, preventing trapped moisture. Avoid plastic tarps or rubber-backed mats, as they can trap condensation and cause damage.

How to Secure Outdoor Furniture Without Damaging Brick

Winter storms in D.C. can send unsecured furniture sliding across patios or into masonry walls. Move furniture away from fragile edges and use pads under metal legs to prevent rust stains. Store lightweight items before storms and use weighted anchors for larger pieces. When securing anything outdoors, rely on removable methods rather than brackets or hardware drilled into brick.

What Not to Use on Historic Brick and Masonry

Some common products and practices can damage historic masonry. It’s best to avoid the following for patios, walkways, retaining walls, or any exterior brick:

• Salt or chemical de-icers
• High-pressure washing
• Drilling into brick or mortar
• Tight plastic coverings
• Metal shovels that crack brick edges

For traction on icy patios, use sand or fine gravel instead.
