Water and how if effects your chimney.

Water damages chimney’s, HOW??

Every year when we get lots of call several days after it rains with complaints of wet and musty smells coming from the chimney.

Mortar and brick are very prone to water penetration and incursions.  Brick by it very nature are able to absorb lots of water. Brick are made of clay which is dried and cut to correct size and any time you take the water out of a natural material it always is trying to replace that water. It a nature thing.

Protecting the Chimney

In this picture you can see the effects of rain on this chimney. The black looking stuff is mold and mildew that grows on the brick. After it rains the brick, if not property treated, absorb a good amount of water creating a moist environment for mold / mildew to grow in.  Some people confuse with with creosote which is present inside the chimney from burning wood products. 

What can we do to help prevent this?

The proper way to correct this condition and help protect from future damage is to first power wash the outside to remove the mold and mildew buildup. In some cases we see considerable amounts of moss on the bricks as well especially on north facing side of chimneys.

Here you can see the power-washing removing the buildup of mold and mildew and small bits of moss.. This house was not surrounded by large trees so the chimney got less shading.

this chimney had a bit more shade and lots of moss growth.

 

Applying the water repellent treatment. 

After the chimney has dried we spray the water repellent treatment on exterior surfaces.. One comment we get is “should I seal the chimney”.. The answer is NO.. when you seal a chimney you create problem you can not see for many years and then you have a real problem. Why you ask.. when you seal a chimney you are sealing moisture in the structure. A water repellent product is designed to allow for water vapor to escape to allow the structure to naturally dry over time while preventing rains from penetration of surface.

Water propellant product we use are industry standard and proven to be the best, and come with a 10 yr performance warranty.

Crown Repair

Along with power-washing the chimney and applying water repellent treatment we suggest repairing the crown of the chimney. This wash on top of the chimney is made of mortar and is designed to prevent water from entering the top of a chimney structure. However over time the mortar will crack and water can enter.

    Summer is a time for picnic, fun at the beach and birds in the chimney. If you are having an issue with birds, please let them be till they are flying out of the chimney. We can come and clean the mess out, is there is a lot, and put a cap on to help prevent the return.

    ALso, if you had another chimney sweep company come out to clean or check your chimney and leave you with a report that says you need thousands of dollars worth of repairs please give us a call.

    A lot of the thing they "recommend" are to bring your chimney up to 2018 code standards which is not necessary unless you are doing major repairs on the chimney or it is being torn down and rebuilt.
