Bringing an idle fireplace back into use

Long idle, a fireplace may have a chamber full of fallen mortar, a shelf with debris and a damper rusted in place. None of it matters until the first fire, and then all of it matters at once. Mortar crumbs on the hearth can be the first sign that something above has loosened.

Before that first fire in St. Nicholas, we clear and inspect the chamber and shelf, work the damper and check the flue. The written estimate says what must happen before lighting and what can wait. Book the free visit at (904) 920-5495.

St. Nicholas is one of the named neighborhoods of Jacksonville. St. Nicholas falls within Duval County.

The order of a smoke chamber repair

Tell us what the fireplace does
Spilling smoke, a stale smell or grit on the damper plate tells us what to bring to the free visit.
Chamber measured and mapped
Height, width and wall slopes are measured, and each wall, the shelf and the flue transition are checked.
Cleaned, reset, parged
Soot and glaze come off, loose units are reset, joints filled, then refractory mortar goes on in layers.
Cured and draft tested
The product cures as its data sheet directs, then a small fire shows how the fireplace draws.

Framing around an inland chimney in St. Nicholas

Where a chimney in St. Nicholas passes framing, the space between the masonry and the wood is set by the code, not by the climate. Heat that escapes a chamber through open joints reaches that framing first.

We check what we can see around the chamber and note anything closer than the code allows.

Parging or rebuilding the chamber, either one is discounted.

Getting the brick ready to take a coat

Parging bonds only to clean, sound masonry. Soot, loose mortar and any glazed deposit come off first, with brushes, scrapers or a chemical treatment where the glaze demands it. Then the surface is dampened as the product's data sheet directs, since dry brick can pull water out of fresh mortar too fast.

Skipping preparation is the reason parge coats fall off in sheets. We treat it as part of the job, and the estimate lists it as its own step so you can see the time it takes. On a chamber coated with heavy glaze, getting the surface ready can take longer than the parging itself.

The damper frame at the base of the chamber

The throat damper sits in a cast iron or steel frame bedded in the masonry at the bottom of the chamber. Water and heat loosen that bedding, and a rusting frame swells and cracks the mortar around it.

When the frame is loose, we reset it in refractory mortar before the chamber is parged, so the new coat meets a solid base. A damper that no longer works is a separate repair, and the estimate says so rather than burying it in the chamber price. Where a top-sealing damper is planned, the throat frame may come out altogether, and that changes what the base of the chamber needs.

Glazed deposits come off before parging

Glazed creosote is a hard, shiny layer that bonds tightly to masonry. Refractory mortar will not hold on it, so it has to come off the chamber walls before parging. That may take chemical treatment and repeat visits, or mechanical removal, depending on its thickness.

We price glaze removal in the chamber as its own step, with the method named. If the flue above is glazed as well, that is a separate creosote removal job, and the estimate keeps the two apart so you can see each. Once the glaze is off, the brick beneath it is checked for damage the glaze had been hiding.

Before the chamber is parged

How soon can someone look at the smoke chamber in St. Nicholas?

When a slot is free that day, yes. Tell us whether the fireplace smokes, smells or drops debris, and we will bring what the visit needs.

Does a factory-built fireplace have a smoke chamber to repair?

Those units have no masonry smoke chamber, so this service does not apply to them. Their internal parts are repaired with the maker's listed pieces, which is a different job we also handle.
