Our approach to chimney brick and joints

Cracks that run through several bricks

A crack that cuts straight through a row of bricks, rather than following the mortar, suggests a force strong enough to break the units themselves. The brick industry lists this among the signs of a structural issue.

Filling such a crack with mortar does not deal with the force behind it. We describe the crack's path and length in plain words and say when a structural assessment should come before the masonry is priced. If the assessment clears it, the repair then goes ahead with the cause understood.

Why repair mortar should be the softer partner

In a healthy brick wall, the mortar gives way before the brick does. Movement, moisture and salts work through the joints, and joints are far easier to renew than bricks. Both the brick industry and the National Park Service guidance on repointing make this point.

A repair mortar stronger than the brick reverses that order. The stress then lands on the brick edges, and faces start to break. We choose a mortar that is no harder than the brick it sits against, and we say which one on the estimate.

Calling us about chimney brickwork in River Oaks

When you call about chimney masonry in River Oaks, we start with a few questions. Where is the damage, what does it look like and when did you notice it? Has anything fallen, and is the fireplace in use?

We also ask about access, pets and anything connected to the chimney. Loose brick over a walkway may call for the 24/7 line rather than a routine booking, and we tell you if so. Booking the free inspection does not commit you to any repair.

A stain indoors linked to the brick outside

A stain on a wall or ceiling beside the chimney can come from water soaking through the masonry face. It can also come from the flashing, the crown or the roof covering nearby, so the stain alone does not settle it.

We compare the indoor stain with the masonry outside and in the attic. Open joints or soaked brick directly outside the stained area point to the masonry. If the evidence points elsewhere, we say so rather than pricing masonry work that would not stop the stain.

What a chimney masonry estimate lists

  • Gentle cleaning tested on a small area
  • Plant growth removed and joints repaired
  • Access equipment and roof protection
  • Curing care for fresh mortar

Brick and mortar repair questions

Will you look at the crown and flashing during masonry work?

Yes. Water from a cracked top or a failed roof junction often causes the masonry damage in the first place. We note what we find there and list any repair to those parts as its own item.

Do you need to go on the roof for chimney masonry work?

For work above the roof line, usually yes. We plan the route and protection so the roof covering takes as little wear as possible, and we tell you if a roofer needs to lift any covering.

Why do you ask about earlier repairs to the chimney?

Earlier work explains a lot. A patch in hard mortar, sealant over cracks or a repair that failed quickly all change what we look for and how the new repair should be done.
