Chimney Crown Repair in North New Jersey

The crown is the concrete slab at the very top of the chimney that slopes water away from the flue. When it cracks, water seeps straight into the masonry, and in a New Jersey winter that water freezes, expands and tears the chimney apart from the inside.

We repair the crown with a high quality masonry sealant and crown repair mortar made for the job. Done right, it restores a smooth, watertight surface that protects the whole structure for years.

Pricing: every job is different, so we give you a free written quote after we inspect. You approve the price before any work begins, with no surprises.

Why it matters in North New Jersey

Crown cracks are one of the most common and most overlooked problems we find on North Jersey chimneys. Because the crown is out of sight at the very top, small cracks go unnoticed until water has already worked its way down into the brick. Catching it early is far cheaper than a rebuild.
