To determine the condition of your chimney, a close inspection or assessment is necessary.

One of the best ways to do this is by calling a professional to have it checked. Chimney technicians know the common signs to look out for in determining what actions (whether maintenance or replacement) to take.

Replacing Chimney Parts Vs Replacing the Entire Chimney Structure

In trying to fix your chimney, a decision will have to be made. Making this decision rests entirely on the condition of your chimney. In other words, certain chimneys may only require maintenance work such as the replacement of worn-out parts.

In other cases, your entire chimney may require complete replacement. So, how can you know if your chimney maintenance needs fall under the former or latter category? You’ll need an expert to figure this out. Chimney technicians are professionals that inspect the functionality of your chimney.

This enables them to conclude whether replacements are limited to certain parts of the chimney or total revamping is necessary. In any case, you should be prepared as urgent repairs will prove very beneficial.

Now, there are several chimney parts. How functional they are will determine whether they need to be changed or not.

Replaceable parts include chimney liners, chimney caps, stove pipe, chimney pipe, chimneypots, gas vent pipe, and direct vent pipe. Other replaceable chimney parts include pellet vent pipe, chimney plugs, exhaust fans, chimney surrounds, double-wall stovepipes, and more.

Not all chimneys are the same. There are different types based on the fuel being used. As such, parts may vary.

How To Know When Your Chimney Is Due For Replacement

There are always signs to watch out for during chimney inspection. These signs point to a failing chimney system hence the need to have them fixed or replaced.

They include white salts on bricks, absence of chimney cap, damaged crown, spalling, leaning chimney, worn, or cracked flue liner.

  • White Salts on Bricks

Whenever you observe white salts on the surface of bricks, it points to one thing; water damage. When water seeps through bricks continually, white salts are observed on the surface.

Such observations are signs of gradual deterioration of your chimney structure.

You’ll need to call in the technicians for further assessment as certain parts of your chimney may be due for replacement.

  • Absence of Chimney Cap

A chimney cap is an essential component of your chimney without which severe damage can be caused to your structure. As such, you’ll need to have this part of your chimney replaced immediately.

So, what benefits are derived from the chimney cap? There are several!

First, a chimney cap will keep out water from getting into your chimney.

Without this, rainwater easily gets in resulting in damage to walls, attic, and ceilings. This part of your chimney also helps keep out critters, birds, rodents, and reptiles such as snakes from using it as an entry into your home.

  • Damaged Crown

A chimney crown helps protect it from damage resulting from the elements.

Having a damaged chimney crown will cause significant problems hence the need for replacement. To ensure it remains in perfect working condition, your chimney crown should be inspected yearly and fixed immediately when the need arises.

Further delay will only compound the problem as such damage widens. You may end up paying more for a complete overhaul or replacement of your chimney if you don’t act fast.

  • Spalling or Shaling

Spalling is usually evident whenever you notice your chimney walls flaking or peeling off. When this is noticed, it only means one thing; a gradual deterioration of your structure caused by the water.

In the case of shaling, you’re likely to notice tiles falling into your fireplace.

Any of these two conditions is a result of damage caused by water. The best action to take is to call for professional help immediately. A replacement of your chimney may be necessary to fix this problem.

  • Leaning Chimney

One of the scariest things to deal with is a leaning chimney. This is a disaster waiting to happen as it could easily crumble under its uneven weight. To prevent this from happening, it’s advisable to call for immediate replacement.

Although getting this fixed may result in a lot of expenses, it’s worth it and helps prevent injuries or worse due to sudden chimney collapse.

  • Worn or Cracked Flue Liner

Chimney liners are essential to the proper functioning of every chimney. These help with the expulsion of heat, combustibles, and gases outside. Liners eventually get worn out or cracked as time passes, thus resulting in improper functioning.

To have a flue liner fixed, you’ll need to call for the replacement of this part of your chimney. The earlier this task is carried out the better it is for your chimney to function efficiently.

  • Roof Leakage

Roof leakage is another reason to call for chimney replacement. However, not all roof leaks require this approach. The extent of the leak will determine what actions to take. The best approach is by calling a chimney technician to conduct inspections.

The inspections carried out are thorough and seek to identify the source of the leak. If it’s determined that the leak is due to a structural defect, then the chimney will have to be replaced.

How To Replace A Chimney Step By Step

Before conclusions are reached for chimney replacement, a proper inspection will need to be carried out.

Where’s the Fault Situated?

A chimney can be divided into two main sections. These include the breast and the stack sections. The breast is the most visible part of the chimney. Wherever this part of the structure follows, it’s likely to be seen protruding in rooms among other spaces.

The stack on the other hand is the part of the chimney that is seen from outside. It rises from the roof and has a cap. Sometimes replacement work may be restricted to certain sections, while at other times, both sections may be involved.

Who to Consult
