What goes into a chimney rebuild in Sanford
Rebuild checkpoints in Sanford, with the code and guidance behind each one.
When the chimney pulls away from the wall
A widening gap between a chimney and the wall beside it means one of them has moved. Brick industry guidance for single-wythe chimneys describes attaching them to the structure with corrosion-resistant metal ties, and those ties can rust through or pull loose over time.
Closing the gap with sealant hides the movement without stopping it. We look at where the gap is widest, whether the chimney is tipping away at the top and what is happening at the base. Then we explain whether new ties, a partial rebuild or a structural review is the right next step, and what each would involve.
We also measure the gap on the first visit, so if you choose to watch it for a while before deciding, there is a starting figure to compare against later.
Stepped-out brick and corbel limits
Many chimneys step outward where they change size, a detail called corbeling. The Florida Building Code, Residential, sets limits on it. Corbeling from a wall or foundation may not exceed half the chimney wall's thickness, and a wall thinner than 12 inches can carry a corbeled chimney only when the chimney projects equally on both sides.
When a rebuild reaches a corbeled section, the new courses have to follow those limits even if the old work did not. We check the existing steps before planning the rebuild and explain any change to the chimney's shape that the code requires, before any brick is ordered.
Corbeled steps are also places where water sits on the top of each ledge, so we check those ledges for washed-out mortar and plan a properly shaped wash or tooled joint on each one.
Records you keep after the rebuild
When the job is finished, you get a written record of what was rebuilt: where the new work starts, the materials used, the flue lining and the cap. Keep it with your house papers.
That record helps with future inspections, a home sale or later work on the roof, because the next person can see what was done and when. It also sets out what our workmanship warranty covers, so you know exactly what we stand behind. If anything changes on the rebuilt chimney later, call us with the details and we will come and look.
The record also notes the date the fireplace was cleared for use again, which is useful if the chimney is looked at later by a home inspector or another contractor.
