Creosote

Creosote is a tar-like substance that builds up in chimneys when wood is burned. It's highly flammable and can cause chimney fires if not removed regularly. In Redwood City's older homes, creosote buildup is common due to the age of the chimneys. Regular chimney sweep services can help prevent creosote-related issues.

Flue

A flue is the passageway inside a chimney that allows gases to escape. It's typically made of clay, metal, or ceramic materials and needs to be properly maintained to ensure safe and efficient chimney function.

Flue liner

A flue liner is a protective layer installed inside a chimney flue to prevent damage from heat and corrosive gases. In Redwood City, where many homes have older chimneys, flue liners are essential for maintaining safety and efficiency. Learn more about chimney liner installation and repair in our blog.

Damper

A damper is a metal valve that controls airflow in a chimney, allowing you to regulate the amount of air that enters the fireplace. Proper damper function is crucial for safe and efficient chimney operation.

Chimney crown

The chimney crown is the top layer of a chimney, typically made of concrete or stone, that protects the chimney from weather damage. In Redwood City's wet climate, a well-maintained chimney crown is essential for preventing water damage and ensuring the longevity of your chimney.

Chimney cap

A chimney cap is a metal or stone cover that fits over the top of a chimney to prevent debris and animals from entering. It also helps to prevent water damage and reduce the risk of chimney fires. Check our pricing guide for chimney cap installation costs.

Firebox

The firebox is the area where the fire is burned in a fireplace. It's typically made of brick, stone, or metal and needs to be properly maintained to ensure safe and efficient fireplace operation.

Smoke chamber

The smoke chamber is the area above the firebox where smoke and gases collect before entering the chimney. It's an essential component of a chimney system and requires regular maintenance to ensure safe and efficient operation.

Draft

Draft refers to the flow of air in a chimney, which is essential for proper chimney function. A well-maintained chimney with a good draft can help to improve fireplace efficiency and reduce the risk of chimney fires.

Spalling

Spalling is a process where brick or stone surfaces deteriorate due to weathering or heat damage. In Redwood City's older homes, spalling is common and can lead to serious safety issues if left unchecked. Our team can help with spalling repair services to ensure your chimney remains safe and functional.

Tuckpointing

Tuckpointing is a process of repairing mortar joints in brick or stone structures, including chimneys. It's an essential maintenance task for older homes in Redwood City, where weathering and heat damage can cause mortar joints to deteriorate. Learn more about tuckpointing and other maintenance tasks in our tips section.

Chimney flashing

Chimney flashing refers to the seal between a chimney and a roof, which is designed to prevent water damage. In Redwood City's rainy climate, properly installed and maintained chimney flashing is crucial for preventing water damage and ensuring the longevity of your chimney.

Level 1 / Level 2 inspection

A Level 1 inspection is a basic visual examination of a chimney, while a Level 2 inspection is a more detailed examination that may involve camera equipment and other tools. In Redwood City, our team provides both Level 1 and Level 2 inspections to ensure your chimney is safe and functional.
