Stone Chimney Repointing in Delaware County, PA

At Jim Murray’s Chimney Service, we take pride in helping local homeowners protect and preserve one of the most important features of their homes – the chimney. Recently, our team was called out to a home in Delaware County, PA where a beautiful stone chimney was showing signs of age. The mortar between the stones had begun to crumble, leaving gaps that could lead to water leaks and structural damage if left untreated.

To restore both the safety and appearance of this chimney, we completed a full repointing project, carefully removing the deteriorated mortar and replacing it with fresh, durable joints. The result? A sturdy, weather-resistant chimney that looks as good as new and will stand strong for years to come.

What Is Chimney Repointing and Why Does It Matter?

Over time, the mortar joints that hold a brick or stone chimney together begin to break down due to weather, age, and exposure to moisture. When those joints deteriorate, it can allow water to seep in, which leads to internal damage, staining, leaks inside your home, and even structural instability.

Chimney repointing is the process of removing old, failing mortar and replacing it with new mortar that matches the original in color and strength. This not only reinforces the chimney structurally, but it also restores its appearance, protecting your home and increasing curb appeal.

About This Project

For this Delaware County homeowner, the problem was clear: the once-solid mortar joints had cracked and started to crumble. Water was finding its way into the gaps, creating the risk of further damage.

Here’s how we handled the project from start to finish:

  • We began with a thorough inspection to assess the condition of the stone chimney.

  • Damaged mortar was carefully removed, ensuring the surrounding stonework stayed intact.

  • We applied fresh mortar, chosen to match the original style and color so that the repair blended seamlessly with the existing stone.

  • After completing the repointing, we inspected the chimney again to confirm its structural integrity and clean, finished appearance.

The completed project not only sealed the chimney from future water intrusion, but also brought back its classic, timeless look.

Signs Your Chimney May Need Repointing

Not sure if your chimney needs work? Here are a few signs that it’s time to schedule an inspection:

  • Cracked, crumbling, or missing mortar between stones or bricks

  • White staining (efflorescence) on the exterior of the chimney

Catching these issues early can prevent costly damage later.
