What Is the Point of a Chimney Liner?

You have been searching tirelessly for the right historical house to make your new home, and you finally found the perfect one to buy. However, when you get the report from the Level 2 professional chimney inspection you need before you can make an offer on the home, you discover that the chimney is missing a liner. Since chimney liners were not mandated by most The Point of a Chimney Liner - Poughkeepsie NY - All Seasons Chimneylocal building codes before the 1940’s, it is not uncommon to see unlined chimneys in historic homes, and because of this, All Seasons Chimney is very familiar and experienced with bringing these chimneys up to modern safety codes and standards. For over 25 years, we have been providing professional chimney lining services to the residents of the Poughkeepsie area, and we can help you make the historical home of your dreams a reality by installing the best type of liner for the chimney. We are often asked why chimney liners are so important, and we would like to tell you more about the point of this essential chimney component.

PROTECT YOUR HOME FROM HEAT TRANSFER

The reason why most local cities and municipalities began mandating chimney liners in the 1940’s has to do with the results of tests given by the National Bureau of Standards (NBS) concerning the safety of masonry chimneys. According to the Chimney Safety Institute of America (CSIA), the NBS found that heat moved so quickly through an unlined chimney that it ignited the adjacent woodwork in less than three and a half hours. This is why the NBS stated that building a chimney without a liner was so unsafe that it was “little less than criminal.” All Seasons Chimney can protect your home from the risk of an accidental fire by installing a durable stainless steel liner inside your chimney to stop heat transfer from occurring.

PREVENTS CORROSIVE MASONRY DAMAGE

Without a liner in place, the bricks and mortar joints of your chimney are at risk of damage by the corrosive and acidic byproducts of combustion. A chimney liner protects the masonry materials from being penetrated by flue gases, which can cause serious erosion damage. This type of masonry damage can deteriorate rapidly, and it can lead to dangerous hazards including heat transfers and carbon monoxide leaks. Our CSIA-certified chimney experts at All Seasons Chimney place your safety at the highest priority, and we can recommend the best liners to give your bricks and mortar joints the most ultimate protection against corrosive combustion gases.

PROVIDES A CORRECTLY-SIZED FLUE

A popular way to increase the energy efficiency of your home is to install a new gas insert inside your existing fireplace opening. To make sure your new fireplace insert works at its highest level of efficiency, it is important that the flue size matches the size of the insert. Typically, masonry chimneys are much larger than fireplace inserts, but All Seasons Chimney knows how to solve this problem by installing a custom sized stainless steel liner to give your insert a properly sized flue. We can also perform this service if you currently have a mismatched sized flue for your existing hearth appliance.

In order to function safely and efficiently, your chimney needs several important components, including the liner, in place. Contact us today at All Seasons Chimney to learn more about our professional chimney relining services.

If You Like It, You Should Put a Chimney Crown on It

For over 25 years, All Seasons Chimney has specialized in leaky chimneys, and we know the best ways to keep water out of your chimney.

What exactly is a chimney crown?

If You Like It You Should Put a Chimney Crown On It - Poughkeepsie NY - All Seasons ChimneyThe top element of a masonry chimney, the chimney crown serves to cover and seal the top of the chimney from the liner to the edge of the chimney, according to the Chimney Safety Institute of America (CSIA). Without a chimney crown, water from rain, melted ice, and snow can easily enter your home through your chimney. To best protect your chimney, it is important to follow certain details during construction such as the type of mortar mix and the slope of the crown.

Why are these details so important during chimney crown construction?

When we construct a chimney crown, we make sure to use a Portland cement-based mortar mix. It is durable enough to withstand years of weather abuse and not crack or crumble. We will also apply a coat of a waterproofing agent to the crown to prevent water penetration damage. Our CSIA-certified chimney technicians also take careful measurements of your chimney. We want to ensure that the crown has the right angle of a downward slope as well as the proper length of an overhanging drip edge to direct the water running off from the crown.

What if my chimney crown is damaged?

Over the years, it is normal for your chimney crown to suffer from erosion damage. That is why we include a check of the chimney crown during our annual inspection service. It is difficult for the untrained eye to see the condition of the crown without getting on your roof. If we find cracks, gaps, or other damage rendering your crown ineffective, we can make necessary repairs. If the damage to the crown is beyond repair, we can also construct a new crown for you. We also provide you with photographs of the damage and a written estimate of necessary repairs.

Along with our chimney crown construction and repair services, All Seasons Chimney provides other professional water penetration prevention services, including chimney cap installation and waterproofing.
