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.

Why You Should Waterproof Your Chimney Image - Poughkeepsie NY - All Seasons ChimneyWhat is waterproofing and why does my masonry chimney need it?

Masonry materials are naturally porous. This means the bricks and mortar of your chimney absorb water whenever it rains, sleets, or snows. A professional waterproofing treatment can prevent this from occurring and keep water from causing erosion damage. All Seasons Chimneys only uses waterproofing formulas that are 100 percent vapor permeable. This is important because it allows the masonry materials to breathe. Water is stopped from entering the bricks and mortar, but vapors can leave and not become trapped to cause further damage. After we have applied the waterproofing formula to your chimney, it will be protected from water penetration for at least a decade!

How does water damage my masonry chimney?

When the bricks and mortar absorb water, it begins the erosion process. This is also known as spalling. The greatest amount of damage occurs during the cold months of winter. Each time the temperature falls below the freezing point, any moisture within the masonry materials freezes and expands. As the water thaws when the temperature rises, the force of the thawing can cause the bricks and mortar to crack, break apart. Consequently, it can even become loose and fall from the chimney structure! Repeated freeze/thaw cycles can lead to significant spalling damage. If not repaired, your chimney is vulnerable to more water leaks and to serious structural problems. This includes the collapse of the entire chimney. This is why waterproofing your chimney is such an important preventive maintenance service.

Preventing water penetration of your masonry chimney is essential to keep it working efficiently and safely for many years.
