How we rebuild chimneys in Crystal Point
The Florida Building Code and brick industry guidance, applied to rebuilds in Crystal Point.
How tall the rebuilt chimney must be
The Florida Building Code, Residential, sets a minimum height for chimney tops. The top has to clear the highest point where the chimney passes through the roof by at least 3 feet, and it has to sit at least 2 feet above any part of the house that lies within 10 feet.
A rebuild is the right moment to check that rule, since an older chimney may have been built short or cut down during an earlier roof job. Building to the required height keeps sparks and exhaust clear of the roof. We measure before we start and tell you if the finished top will stand higher than the old one.
Where a higher part of the house, such as a second story or a dormer, sits within 10 feet of the chimney, the extra height can be significant, and we show you the measurement behind the number.
Mortar for a rebuilt chimney
New courses are laid in mortar chosen for a chimney's exposure. For chimneys above grade, the Brick Industry Association's mortar guide recommends Type N, with Type S as the alternate, and it advises using the lowest strength that still meets the job's requirements.
On a partial rebuild the mix also has to sit comfortably beside the older masonry that stays, since a much harder mortar next to softer old brick concentrates stress in the old work. We name the mortar on your estimate and explain why it suits both the new brick and the chimney below it.
The new joints are tooled once the mortar reaches the right firmness, which compresses the surface and helps the fresh work shed rain from the first storm onward.
What a rebuild estimate should show
A rebuild estimate should read like a plan. Ours shows where the teardown stops, the number of new courses, the brick and mortar, the crown, the flue lining decision, the flashing and cap, and access, each with its own price.
That lets you compare quotes by what they include instead of by the total alone. Our pricing is upfront with no hidden fees, and a rebuild confirmed within 72 hours of the inspection is 10% off. The inspection and the estimate are both free, and our team will go through any line with you before you decide.
If a line on another quote is missing from ours, or the other way round, ask us about it. We would rather explain the difference than have you compare two different jobs.
