The masonry, mantel, and surround stay; the drafty open firebox inside them gets a sealed wood-burning unit and a full-length insulated liner. Cool-season fires, and a flue that's closed to humidity and canopy debris the rest of the year.

An open masonry fireplace in South Florida spends most of the year as a hole in the building envelope. Original throat dampers in Pinecrest fireboxes rarely seal after decades of humidity working on the plate and hinge, so cooled indoor air escapes up the flue all summer while damp outside air and leaf litter from the oak canopy work their way down. A wood-burning insert closes that hole: a sealed steel firebox fitted into the old opening, vented through a full-length insulated stainless liner, with a gasketed glass door and controlled combustion air. You get real fires on the cool nights and a closed flue every other day of the year.
Pinecrest's housing stock takes to inserts unusually well. The ranch homes built here from the fifties through the seventies carry solid masonry fireplaces with generous openings, and many of the newer Mediterranean-style estates have oversized fireboxes that were designed for looks and never drafted properly. Either way, nothing structural changes — the brick, the surround, and the mantel all stay. We measure the opening, hearth extension, and flue height, select a unit sized to the space, run and insulate the liner, and scribe the trim to the masonry so the finished face looks like it was always there. Free written estimates, upfront pricing with no hidden fees, and a workmanship warranty on the completed work.




Steel or cast iron fireboxes with gasketed glass doors and controlled combustion air, matched to the dimensions of your masonry fireplace.
An insulated stainless flue liner runs from the insert collar to the termination — the humid, salt-touched air this close to Biscayne Bay is exactly why we spec stainless.
Face trim scribed to the brick, coral rock, or cast stone around the opening, so the surround you chose the house for stays untouched.
The flue is closed off around the liner and finished with a cap that keeps rain, oak leaves, and nesting wildlife out of the system.
We measure the firebox opening, hearth extension, and flue height, walk you through the units that fit, and put the full scope in a free written estimate.
The insulated stainless liner goes in from termination to insert collar, then the unit is set, leveled, connected, and sealed.
Trim is fitted against the existing masonry, the system is test-fired and checked for draft, and we go over the door and air controls before we leave.

Arguably more than up north. The heating season here is short, but the envelope problem runs year-round — an open flue trades conditioned air for humid outside air every day. A sealed insert ends that exchange and still delivers real heat on the December and January nights when you want it.
Usually not — inserts are built for masonry fireboxes, and most factory-built fireplaces are only rated for a matching replacement unit. We can tell you which type you have from the firebox and flue construction, and if yours is factory-built we'll walk you through the replacement path instead.
The insert's liner becomes the only venting route. The original throat damper is fixed open or removed, the flue is sealed around the liner at the top, and the termination cap closes the system to rain and canopy debris. Nothing is left open to the weather.
