Philadelphia is famous for its historic row homes, brownstones, and brick buildings that give the city its charm. Many of these structures have stood for over a century, but they require regular care—especially when it comes to masonry maintenance.
Brick, stone, and mortar naturally wear down over time due to weather, pollution, and moisture. Without upkeep, this can lead to serious structural problems. In this blog, we’ll share the top masonry maintenance tips for Philadelphia homeowners and explain how professional services can protect and preserve your historic property.
Why Masonry Maintenance Matters
Unlike newer homes, historic Philadelphia properties were often built using lime-based mortar and handmade bricks. These materials, while durable, are more porous than modern construction products.
Regular maintenance helps you:
- Prevent costly repairs by catching small issues early.
- Protect your home’s structural stability.
- Maintain its historic appearance and charm.
- Increase property value and curb appeal.
Masonry Maintenance Tips for Historic Homes in Philadelphia
1. Schedule Routine Inspections
At least once or twice a year, walk around your property to look for:
- Cracks in the mortar or bricks.
- Loose or spalling (flaking) bricks.
- Water stains or white powdery residue (efflorescence).
- Bowing or leaning walls.
Professional inspections are even better, as experts can identify hidden issues.
2. Repointing Damaged Mortar
Mortar is the “glue” that holds bricks and stones together. Over time, it erodes, creating gaps where water can seep in.
Repointing involves carefully removing damaged mortar and replacing it with new mortar that matches your home’s historic style. Done properly, repointing can extend the life of your masonry by decades.
3. Seal and Protect Against Moisture
Philadelphia’s freeze-thaw cycles cause water to expand inside bricks, leading to cracks and crumbling. Applying a breathable masonry sealer can protect against water infiltration while still allowing the walls to “breathe.”
4. Address Water Drainage Issues
Poor drainage is one of the biggest threats to masonry. Make sure:
- Gutters and downspouts are clear and working.
- Water is directed away from your foundation.
- Landscaping slopes away from your home.
5. Repair Cracks Early
Small cracks may not seem urgent, but they allow water to seep in and cause bigger problems. Professional masonry contractors can use specialized techniques to repair cracks before they spread.
6. Avoid Harsh Cleaning Methods
Power washing or using strong acids can permanently damage historic brick and stone. Instead, use gentle cleaning methods designed for masonry, or hire professionals for safe restoration.
7. Invest in Professional Masonry Services
DIY repairs can cause more harm than good—especially on historic homes. Professional masons understand the proper materials and techniques needed to preserve your property’s structural integrity and appearance.
