Chimney brick spalling repair from local pros in Edgewood

Replacing units in a solid masonry chimney wall

For new construction, the Florida Building Code, Residential, section R1003.10 describes masonry chimney walls built of solid units, or hollow units grouted solid, at least four inches in nominal thickness.

When a damaged brick comes out of a solid masonry chimney, the replacement has to restore that wall rather than cover a hole with a thin face. We use full units, fully bedded, and if the damage runs deeper than one layer, we explain what the repair needs before going further. Our inspection is not a code approval, but we build the repair to respect how the wall was made.

What the written brick replacement estimate includes

Your estimate lists the approximate number of units, the repair boundary, the replacement brick, the mortar type and color approach, the access method and cleanup. Related items such as crown or flashing repair appear on their own lines.

It also explains how additional damaged units found during removal will be handled, so there is no surprise charge. We use upfront pricing with no hidden fees. Book within 72 hours after the inspection and the estimate shows 10% off.

Testing the original mortar on older chimneys

Where nobody knows the original mortar type, BIA Technical Note 46 suggests a lab test of samples to work out what it contains, in what proportions and how strong it is, and it names ASTM C1324 as the usual method.

For most chimney repairs, a careful visual and hands-on assessment is enough to choose a compatible mix. On older or unusual brickwork where the choice is less clear, we explain the testing option, what it adds and what it costs, so you can decide whether it is worth it.

Questions to ask before approving brick replacement

A good estimate answers these questions in writing. If one is missing, ask before you approve the work, whoever is quoting it.

• How many units will be replaced, and how were they chosen?
• What is thought to be causing the damage, and is it addressed?
• Which brick will be used, and how close will the match be?
• Which mortar type and color approach will be used?
• How will extra damaged units found during removal be handled?
• What cleanup and protection of the roof and yard are included?
