Brick replacement that deals with the cause

Cracks that run through the brick face

A hairline line on the surface of a brick is different from a crack that runs through its face. Brick industry guidance treats cracks extending through the face shell as a reason to replace the unit.

We look at the crack's width, its path and whether the face on either side sits level. A crack through the face can let water into the brick and the wall behind. That unit goes on the replacement list, and we look at what cracked it before choosing the new one.

Loose top courses under a failing crown

Loose bricks at the very top of a chimney are often a sign that the crown and the courses under it have taken water for a long time. The mortar there may have washed out, and several units may lift together.

Replacing a few bricks may not be enough in that case. We explain whether the top courses need relaying before a new crown can sit on them. That work is priced separately, and the brick replacement lower down is planned around it.

When light surface flaking can wait

Some brick shows light surface flaking that has not gone deep and is not spreading quickly. If the unit is firm, the flaking is shallow and water is not getting through, replacing it straight away may not be necessary.

We tell you when that is the case and what to watch for. Deeper loss, a crack through the face or a unit working loose would change the answer. A maintenance visit later can show whether the flaking has progressed, so any replacement happens when it is actually needed.

Spalling concentrated on one face

Spalling can gather on a single face of a chimney while the others stay sound. That face may catch more rain, dry more slowly or sit under a failing section of crown or flashing.

We compare the faces to find what sets the damaged one apart. The brick work may concentrate there, while the cause above or beside it is listed as its own repair. Treating both keeps the new units from wearing down the same way. Mention which side you noticed first, because that order helps.

Answers about chimney brick replacement

How do you match new brick to an older chimney?

We compare size, color, texture and the range of shades in the wall, and we can set out a sample to judge the match. Finding a close brick can take some searching. New brick may look fresher at first.

Will new bricks stop water getting into the house?

They can close an entry point where broken brick lets water in. Water can also enter through the crown, flashing or joints. We explain what the brick work addresses, and a hose water test comes into it only if the job calls for one.

How long does a chimney brick replacement job take?

It depends on how many units are involved, how easy the chimney is to reach and how long a matching brick takes to find. We give you a realistic schedule with the estimate and tell you if anything changes it.
