Masonry Chimney Repair Cost

There’s nothing quite like snuggling up in front of the fireplace on a cold, rainy day during the holidays. And even if your home has been built without a fireplace, you don’t have to miss out on all the comforts it can provide. Nowadays, installing a fireplace or wood-burning stove is easy – and these need a functional chimney.

The most common type of chimney installed in the U.S. is the masonry chimney. Chimneys have different manufacturers, different models, and may be made of brick, concrete blocks, stone, mortar, concrete, flue tile, steel, and even cast iron.

Signs That Your Chimney Needs Repairs

Many people make the mistake simply forgetting about the chimney as if it’s a worry-free part of the house. Nothing can be further from the truth. A damaged chimney can lead to serious problems.

Luckily, there are many signs that indicate that masonry chimney repair may be required:

Chimney crown damage

It will be necessary to go onto the roof and inspect the structure if your chimney crown has been damaged.

Shaling

Spalling

Spalling occurs when bits of masonry starts peeling off and collecting around the bottom on the outside of the structure. Once you notice bits that flake off, repairs are required before the chimney collapses.

Rust

When you look at your fireplace or damper, there should be no rust. If you do find rust, your chimney may be suffering from excess moisture. Visible signs of rust could be an indication of much larger damage.

Deteriorating mortar joints

Damaged mortar joints in your masonry chimney cannot be ignored for too long. If the damaged mortar isn’t repaired, the chimney will collapse. This is most common in colder regions with freezing weather where the moisture can freeze inside the masonry cracks.

Efflorescence 

Efflorescence is the white staining or discoloration of the chimney. Although easy to remove and clean, it doesn’t address the problem of moisture in the chimney. Once you notice efflorescence, repairs may be imminent.

Damaged wallpaper

Wallpaper near the chimney can also give away signs that you might be in need of repairs. Once it displays visible damage, or signs of moisture, it should not be ignored.

How Much Does It Cost To Repair a Masonry Chimney

With all the factors that can affect the cost to repair a masonry chimney, consumers report a national average of anywhere between  $160 – $2,200.

Crown repairs

Crown repairs can come in anywhere between $350- $750. However, there are many variables at play here and in extreme cases, you could be looking at as much as $3,000. On average, however, expect a price tag of between $750 – $1,000. 

Masonry cracks

Masonry joints expand and contract as the temperature fluctuates. Over time, this leads to cracks. When in use, smoke and carbon monoxide, not to mention ash and embers, ends up inside the wall, leading to further deterioration. If you catch the problem early, you could repair some masonry cracks for anywhere between $175 – $300. If the damage is extensive, repairing masonry cracks in your chimney could be as much as $3,000.

Spalling repair

If left untreated, spalling can lead to total destruction of your masonry chimney. Extreme deterioration may require repair of up to $3,000. But catch the problem early, and you could save and have some spalling repairs for $885 – $1,100.

Re-mortaring

When the mortar starts crumbling, you may not need to replace the bricks if you act fast. Re-mortaring is a more affordable option and can cost anywhere between $2 – $3 per sq.ft. On top of that, you can expect $40 – $55 per hour in labor.

Get in Touch With Local Professionals

There are many factors to consider when it comes to your masonry chimney. It’s not something that can simply be ignored once you start to notice the problem.  But as with most home remodeling or repair projects, the only way to get a more accurate idea of what you should be paying is by comparing estimates from local professionals in your area. Not only does this give you the opportunity to compare costs, but also the chance to discuss your options with an expert.
