Chimney Crown Repair Rockville MD: The Finished Result

The new mortar crown stands out in this photo. It covers the top of the brick chimney and surrounds each flue opening.

In addition, two large clay flue tiles rise through the crown. Metal chimney caps protect those flues from above. A smaller vent opening also sits between the two larger flues.

Our crew shaped the new crown across the chimney top to create a clean finished surface. Because this part of the chimney sits above the roof, it takes the full force of rain, snow, sun, and changing temperatures.

Therefore, a sound crown plays an important role in protecting the masonry below.

What the Crown Looked Like Before the Repair

Before this chimney crown repair Rockville MD project, the old crown showed clear signs of age. In particular, cracks had formed near one of the clay flue tiles.

Those cracks created weak areas in the surface. As a result, rain and melting snow had more chances to enter the crown.

Maryland weather can make those problems worse. For example, water can enter a crack during wet weather. Then, when temperatures drop below freezing, that water can freeze and expand. Over time, repeated freezing and thawing can make an existing crack larger.

For this Rockville home, our crew removed the concern by building the new mortar crown shown in the photo.

What Does a Chimney Crown Do?

A chimney crown helps protect the top of a masonry chimney from water. It also helps move rain and melting snow away from the brick and mortar below.

However, the crown takes a lot of weather exposure. Sun, rain, ice, and temperature changes can slowly wear down the surface.

For that reason, homeowners should not ignore cracks or missing mortar at the chimney top. Small problems can grow as water continues to reach the same area.

Also, crown damage can be hard to see from the yard. A professional chimney inspection gives a technician a much closer look without asking the homeowner to climb onto the roof.

A New Liner Kit Was Part of the Project

The photo mainly shows the new crown. However, our crew also installed a new liner kit during this Rockville project.

The liner runs inside the chimney, so you cannot see most of it in this exterior photo. Still, it plays an important role in the chimney system.

A chimney liner gives smoke and gases a path through the chimney. Depending on the system, a chimney may use clay tile, stainless steel, or a cast-in-place liner. In addition, stainless steel is a common choice for many chimney relining projects.

The right liner depends on the appliance and the chimney system. Therefore, a trained chimney professional should inspect the system and choose the correct liner.

Chelsea’s Chimney has CSIA Certified Technicians and a CCR Certified Chimney Reliner. Our team also has OSHA training. In addition, Chelsea’s Chimney is licensed, bonded, and insured under MHIC #115994.

Why Chimney Crown Repair Rockville MD Homes Need Matters

The crown and liner perform different jobs. However, both contribute to a safer and better protected chimney system.

First, the crown helps keep water away from the top of the masonry. Meanwhile, the liner provides the venting path inside the chimney.

Because each part has a different job, chimney repairs should look at the whole system. For example, crown damage may appear at the top while a liner problem exists inside the flue.

That is why a professional inspection can provide useful information before repair work starts.

Signs a Chimney Crown May Need Attention

Homeowners can sometimes spot crown problems from the ground. However, many cracks remain hard to see without a closer inspection.

Common warning signs include visible cracks, loose mortar, missing pieces, or signs of water around the chimney. In addition, older chimney tops may show general wear after years of weather exposure.

A professional can check the crown along with the surrounding brick, mortar, flue tiles, and caps. Therefore, the homeowner gets a clearer picture of the chimney’s condition.
