Common Chimneys Issues That Happen In The Spring

Spring is often the time of year that homeowners notice their chimneys are starting to run into issues. If left untreated, these problems could grow worse and lead to major repairs. The best way to avoid these problems is to have a certified chimney technician come out and inspect your chimney once a year. But that’s not always possible, especially if you live in a warmer climate. 


During the rainy spring months, your chimney may begin to show signs of moisture issues. These may appear as stains on the inside of the chimney or a white stain in sections of the bricks and mortar called efflorescence. These stains can be the first indication that your chimney is absorbing water, which will eventually lead to masonry deterioration. If this is the case, your chimney might need a full rebuild. Another potential issue with your chimney is rusting components. Rust is a sign that the metal in your damper, flashing and chimney cap is decaying due to moisture. When these parts of your chimney deteriorate, it can expose your chimney to water penetration and the risk of mold and mildew damage. A leaking chimney can also cause structural roof damage and make it difficult to repair. 


The spring season brings about a plethora of issues for chimneys. Those issues include animal infestations, a buildup of creosote or soot, and moisture entering the flue. While many people think of chimneys as being a place for wood burning, animals such as birds, squirrels, and other wildlife can also be attracted to the venting systems inside our homes. This can lead to problems such as poor airflow and odors. In the worst cases, these critters can even become trapped inside the chimney, posing a risk of a fire. The most common reason for a chimney to smell in the spring is that it has been saturated with creosote and ash from the winter. This acidic substance clings to the inside of the flue and comes into contact with the muggy air outside, producing a noxious odor that permeates an entire home. 


The winter months can be a tough time for your chimney. The heat and smoke from your fires, freezing temperatures and rain, snow, ice, and sleet can all wear down the mortar, bricks and flashing on your chimney. Spring showers often bring heavy rain, and if your chimney has a leak, it can cause extensive damage to your home. Water seeps into your masonry, causing mold and mildew growth inside the chimney and in other areas of your house. In addition, it can rot your woodwork and spread rust throughout your chimney system. It can also cause your roof to sag and your chimney to collapse. 


A chimney is a complex structure that includes a lot of different pieces and parts. When these components fail, they can wreak havoc on your home and lead to serious problems like leaks, fires, and structural deterioration. Small cracks on the outside of your chimney can grow surprisingly large in the spring as water soaks into your chimney’s masonry. The resulting damage can be severe and may even require extensive repairs.
