How stucco chimney repair is done in Goldsboro
Why the top of the chimney matters
Horizontal surfaces such as the tops of chimneys are particularly vulnerable to water, Preservation Brief 22 notes, and they sometimes need a change to their original design, like added flashing, to correct the problem. On a masonry chimney that top surface is the crown.
In section R1003.9.1, the Florida Building Code, Residential, describes a masonry chimney cap of concrete, metal or stone that slopes to shed water, carries a drip edge and has a caulked bond break where it meets each flue liner. If the crown on your Goldsboro chimney is flat, cracked or missing its drip edge, our team prices that fix on its own line ahead of the stucco.
Stucco on masonry versus stucco on lath
The International Masonry Institute describes two ways stucco is installed. It can be applied directly to masonry, concrete block or concrete, or it can go over lath with building paper or a water-resistive barrier and a drainage provision behind it. Chimneys are built both ways.
The difference matters for every repair decision on your Goldsboro chimney. Direct-applied stucco depends on its bond to the block or brick. Stucco on lath depends on the lath, its fasteners and the barrier behind it staying sound and dry. We confirm which system is there before choosing materials.
Scratch coat, second coat and finish
Preservation Brief 22 walks through the sequence. The first, or scratch, coat is scratched or cross-hatched to give the next coat a key. The second coat is roughened for the finish. Each coat usually needs 24 to 72 hours to dry before the next goes on, and the finish coat is worked to match the original texture.
That means a proper stucco repair on your Goldsboro chimney takes more than one visit. We plan the schedule with you, cover the open work at the end of each day and return for each coat, and the written estimate states how many trips the repair involves.
Painting stucco after the repair
Many stucco chimneys are painted, and the paint has to go back on after a repair. Preservation Brief 22 says the most important factor is that the new paint be compatible with any coating already on the surface, that loose or peeling paint be removed first, and it warns that latex paint will not stick to chalky or powdery areas.
Our crew scrapes loose paint around the repair on your Goldsboro chimney, cleans the surface and recommends a coating that suits both the old paint and the new stucco. Oil-based paint needs new stucco to cure far longer, up to a year according to the brief, so the product choice also sets when the chimney can be painted.
