Crumbling chimney masonry – never ignore these signs
On traditional homes, masonry chimneys look stately, but they are highly susceptible to damage from moisture and day-to-day wear. When chimneys are continually exposed to the elements, deterioration will only accelerate unless they are routinely maintained. It can be difficult to detect the conditions that lead to crumbling chimney masonry. Annual chimney inspections by a professional chimney service can tell them if chimney repair is necessary to prevent widespread crumbling of the brick and mortar. Here are some signs of crumbling chimney which you should never ignore.
Why is it Crumbled?
We are referring to the crumbling of bricks and mortar here. Several factors can contribute to this, including:
- Hailstorms
- Heavy thunderstorms
- Earthquakes
- Flooding
- Old Age
- Poorly constructed chimneys
- Repeated bad weathers
- Poor or no maintenance
Some of these damage types can’t be prevented, but repairs can be made to any type of masonry damage. It is quite common for masonry to crumble as a result of water infiltration.
Chimney Leak Inspection
There are a few signs you should watch out for if you suspect a leak in your chimney:
- Crumbly roof masonry
- Badly discolored ceilings or walls
- Loose or cracked bricks
- A cracked chimney crown
- Near the chimney, water dripping into the firebox
- Bad smells coming from the fireplace
- Efflorescence on the chimney exterior
- Damaged chimney liners or damaged internal walls
A chimney professional should be contacted if any of these signs are visible. A chimney flue inspection may be necessary to evaluate problems inside this structure.
Repair Leaky Chimney
Water will find its way in through cracks in the mortar joints and bricks of your chimney during rain and melting snow. As the moisture rests there, the materials begin to erode slowly. When moisture freezes and expands, it causes damage rapidly during cold weather.
Early detection of this problem can help repair it and prevent it from recurring. Water repellents can be used to fill small cracks in the chimney structure, which will hinder water from entering the system. The process of tuckpointing can often resolve significant crumbling and brick problems, which involves scraping away decayed mortar and replacing it with a new compound.
It might be necessary to rebuild the chimney completely or partially in cases of significant damage to restore safety and performance.
Pro-Tips
One of the most effective ways to prevent significant damage is to have your chimney inspected each year by a skilled chimney technician. Rather than relying on yourself, a professional can evaluate the extent of damage, what caused it, and where the damage actually is. Many chimney contractors can also handle chimney cleaning as well as chimney repairing and rebuilding.
It is important to perform minor repairs as needed in order to maintain your chimney’s performance. You should not ignore crumbling chimney masonry as it is an early warning sign of a problem.
