What Causes Chimneys To Need Repair?

Chimneys made with mortar, brick or stone have one common enemy. That is moisture intrusion. If moisture can work it's way into your mortar and in behind and in between the brick and/or stone it will cause major problems. The problem is made much worse with the cold winter weather we experience here in Massachusetts. As the water gets in, it can freeze (which expands) and causes tiny cracks, which grow into larger cracks and eventual weakening of the structure.

The continual heating, cooling and freezing cycles that most chimneys go through are very taxing on the mortar that binds the chimney together. If not monitored small problems can become much larger issues quickly.

Improperly Built

Not all fireplaces and chimneys are constructed equally. The picture above shows how the exterior brick wall of the chimney was used for the construction of the smoke chamber. It should have yet another wall isolating that brickwork, thus preventing cracking on the outside wall.

If you have a chimney or multiple chimneys on your home or building that need repairing then JB Mohler Masonry can provide you with a realistic assessment for repair. We will provide a solution that is long lasting, safe and as financially minimal as possible. You can have piece of mind knowing that we have over 20 years experience in fireplace and chimney construction to the highest industry standards.

What Causes A Brick Or Stone Chimney To Need Repair?

Brick or stone chimneys, while durable and aesthetically pleasing, are subject to a variety of factors that can lead to their deterioration and the need for repair. Understanding these causes can help homeowners in Central Massachusetts maintain their chimneys and address issues before they become severe.

Moisture Infiltration

Moisture is one of the most common and damaging factors affecting chimneys. Water can enter the chimney structure through cracks, damaged mortar, or a compromised chimney crown. Over time, the freeze-thaw cycle causes water to expand and contract within the masonry, leading to spalling (flaking of the brick or stone surface), cracks, and deteriorating mortar joints. Moisture infiltration can also cause rusting of metal components, such as the damper and flue liner, further compromising the chimney's integrity.

Thermal Expansion and Contraction

Chimneys are exposed to constant heating and cooling cycles, especially during the colder months when the fireplace is in use. The repeated expansion and contraction of the masonry materials can cause cracks in the bricks, stones, and mortar joints. Over time, these small cracks can widen, leading to significant structural issues that require repair.

Settling and Foundation Issues

The foundation of a home can shift due to soil movement, causing the chimney to settle unevenly. This can result in cracks and instability in the chimney structure. Foundation issues are particularly problematic for taller chimneys, which are more susceptible to leaning or separating from the house if the base is not stable.

Creosote Buildup and Chimney Fires

Creosote, a byproduct of burning wood, can accumulate inside the chimney flue. If not regularly cleaned, this highly flammable substance can ignite, causing a chimney fire. Chimney fires can reach extremely high temperatures, causing cracks in the flue liner, bricks, and mortar, and potentially leading to structural failure.

Improper Construction or Repairs

Chimneys that are not constructed or repaired according to industry standards can experience premature failure. Improper mortar mixtures, inadequate flashing installation, and incorrect bricklaying techniques can all contribute to a chimney's structural weaknesses. Ensuring that a qualified and experienced mason performs any construction or repair work is essential to maintaining the chimney's integrity.

Environmental Factors

Environmental factors such as high winds, seismic activity, and severe weather conditions can also contribute to chimney damage. In regions prone to such conditions, regular inspections and maintenance are important to identify and address potential issues before they lead to significant damage.

Wear and Tear Over Time

Even the most well-constructed chimneys will experience wear and tear over time. Constant exposure to the elements, combined with the natural aging of materials, can lead to a gradual decline in structural integrity. Regular maintenance and timely repairs are key to extending the lifespan of a chimney.

By understanding these common causes of chimney damage, homeowners can take proactive measures to maintain their brick or stone chimneys and ensure their safety and functionality. Regular inspections, professional maintenance, and timely repairs by experienced masons like those at JB Mohler Masonry can help prevent minor issues from becoming major problems.

Do You Have Questions About Chimney Repair Services?

What are the common signs that my chimney needs repair?

What causes damage to brick or stone chimneys?

Damage to brick or stone chimneys can be caused by moisture infiltration, thermal expansion and contraction, settling and foundation issues, creosote buildup and chimney fires, improper construction or repairs, environmental factors, and general wear and tear over time.

How often should I have my chimney inspected?

It is recommended to have your chimney inspected at least once a year, ideally before the heating season begins. Regular inspections help identify potential issues early and ensure your chimney remains safe and functional.

Can chimney repairs be done in winter?

While some chimney repairs can be challenging in cold weather due to freezing temperatures, many repairs can still be performed with proper precautions. We use specialized techniques and materials to ensure effective repairs during the winter months.

How can I prevent future damage to my chimney?

If you suspect your chimney has been damaged by a fire, you should immediately cease using the fireplace and contact a professional for an inspection. Chimney fires can cause significant structural damage that must be addressed to ensure the safety of your home.

What is a chimney crown, and why is it important?

A chimney crown is the top, external part of the chimney that covers and seals the top of the masonry walls. It is important because it helps protect the chimney from weather elements, preventing water from entering and causing damage to the bricks, mortar, and flue liner.

How do I know if my chimney crown needs repair?

Signs that your chimney crown needs repair include visible cracks or crumbling in the crown, water leaks inside the chimney, rusting of the damper or firebox, and moss or algae growth on the chimney exterior. If you notice any of these signs, it’s important to have your chimney crown inspected and repaired promptly.

Can you replace a damaged chimney crown?

Yes, we can replace a damaged chimney crown. Our skilled masons will remove the old, damaged crown and install a new one made from durable materials designed to withstand the elements and protect your chimney.
