Fast, Reliable Chimney Repair Across Olympia Heights
Chimney repair in Olympia Heights typically runs $220 – $1,850 depending on scope: a cap replacement lands between $220 – $480, a chimney liner installation between $1,200 – $3,800, and mortar repointing or tuckpointing usually $35 – $55 per square foot. Most repairs in Olympia Heights are booked within 3 – 5 business days, not because we’re slow, but because we schedule the right crew with the right materials. Our Chimney Repair team works with the housing stock here: 1950s and 1960s masonry chimneys with clay tile liners, salt-corroded dampers, and mortar joints that have been soaking up Miami humidity for fifty years. If you live in Olympia Heights and you see flaking brick, a rusty chimney cap, or a fireplace that smells like a wet basement, call (786) 305-7861 and we’ll put a camera up the flue before we quote anything. That camera footage is yours to keep.

Why Flint Chimney Co Miami Is Olympia Heights’s Preferred Chimney Repair Company
We don’t ask Olympia Heights homeowners to take our word for anything. Every repair recommendation comes with visual proof: a live camera feed or recorded footage showing exactly what we saw inside the flue. That matters here because the homes are older. A 1964 ranch near Bird Road and a 1970s split-level off SW 40th Street both have chimneys that predate modern liner standards, and both are prime targets for the kind of upsell where a company tells you the liner is shot and you have no way to verify it. We show you the cracks. Then we give you a written price. If the liner isn’t cracked, we say so and charge you for the sweep or inspection instead. That’s the whole business model.
Hank Delano runs Flint Chimney Co Miami, and the standard is The Garrison Standard: written price before work starts, 365-Day Done Right Promise on every repair, and a free return visit if a covered repair fails inside that year. Technicians who knock on your door in Olympia Heights are background-checked and uniformed. The phone is answered by a live person, 24 hours a day, seven days a week. No voicemail tree, no callback form. You call, a person picks up.
Our crews serve Olympia Heights from the South FL metro office, so scheduling is straightforward and local knowledge is baked in. We know the difference between a chimney in Bird Lakes, where 1960s split-levels needed dampers replaced decades ago, and newer construction near Tropical Park where the chimney might see even less use. That local familiarity shapes what we inspect first and what we tell you can safely wait.
Styles & brands we work with





Chimney Cap Replacement in Olympia Heights
Chimney Cap Replacement in Olympia Heights usually runs $220 – $480 depending on the cap material and whether we need to re-flash the mounting area. The cap sits on top of the chimney and does two jobs: it keeps rain from pouring directly down the flue, and it keeps birds, squirrels, and raccoons from nesting inside. In Olympia Heights, the bigger variable is corrosion. Salt-laden air off the Atlantic and Biscayne Bay eats through galvanized caps within a few years. We regularly replace caps that have rusted through at the seams and let water drip straight onto the damper below.
Signs Your Cap Is Failing
Rust streaking down the chimney crown or the exterior brick is the simplest tell. You may also hear birds or rustling sounds in the chimney, or find small puddles inside the firebox after a heavy summer storm. A seized or rusted cap can also trap moisture against the flue tiles, accelerating spalling on the brick below.
What We Install
We specify caps by job, not by margin. For most Olympia Heights homes with masonry chimneys, that means a stainless steel cap from Gelco or Copperfield sized to the flue and mounted with a proper storm collar. If the old cap rusted out, we want to know why. Sometimes the flue crown itself has sloped toward the flue and funnels water under the cap. We check that before we bolt the new one on.
Chimney Liner Installation in Olympia Heights
Chimney Liner Installation in Olympia Heights typically costs between $1,200 and $3,800 for a stainless steel system like DuraFlex, and it’s the repair we discuss most often with homeowners in the western and northern sections of Olympia Heights. Many of these chimneys were built before 1985, when local code did not require a listed liner. Some have no liner at all. Some have original clay tile liners that have cracked from rare but intense thermal cycling: a holiday fire here, a cold snap fire there, and the clay expands and contracts until hairline fractures let heat and gases reach the masonry and, in time, framing.
The Unlined Chimney Problem
A 1959 ranch in Olympia Heights might vent a furnace through a bare brick flue. The mortar inside those flues erodes after decades of exposure to condensation and acidic exhaust. Once gaps open in the mortar, the flue can’t contain heat or carbon monoxide the way it was meant to. Relining that flue is not an upgrade; it’s the difference between a safe exhaust path and one that leaks into the home.

How We Confirm a Liner Needs Replacement
We don’t recommend relining on suspicion. We run a camera up the flue and show you the footage. If the clay tile has hairline cracks but no gaps and the chimney drafts fine, we will tell you that and suggest a sweep and a re-inspection next season. If the cracks are wide, the joints are separated, or the tile has shifted, we will show you that too, and then give you a written quote for a DuraFlex stainless liner, sized to the flue and installed to the manufacturer’s spec. No guesswork and no “trust me” pricing.
Trusted Brands We Service in Olympia Heights
We stock and install parts from Famco, Gelco, and Copperfield, and we specify these by the job, not by what’s on the truck. A Famco damper goes into a 1970s split-level if the original damper has rusted through and seized; a Copperfield or Gelco cap fits the flue size that the masonry actually has. DuraFlex stainless liners are our standard for relining clay tile or unlined flues in older Olympia Heights homes, because stainless holds up to the humid, salt-laden air here better than aluminum. We keep common cap sizes and damper assemblies staged for Olympia Heights calls, so a cap replacement often takes one visit and under an hour once the crew has the chimney opened up.

AfterCommon Chimney Repair Problems We See in Olympia Heights Homes
- Clay tile liner cracks from rare but hot fires. Olympia Heights chimneys get used a handful of times a year, usually around the holidays, and the tiles expand and contract a lot when the fire is lit and then quickly cool with the humidity. Hairline cracks appear, then widen.
- Rusted dampers from salt air. The same breeze that corrodes air conditioner coils rusts chimney dampers. A damper that seizes open lets conditioned air escape year-round, and one that seizes shut makes lighting a fire impossible. We replace rusted dampers with stainless units from Famco.
- Spalling brick and deteriorated mortar on exterior chimneys. Water soaks into the brick during summer storms, then the salt-laden humidity slows drying and expands inside the pores. The brick face flakes off, and the mortar bedding crumbles. This is a structural issue that gets worse every rainy season.
- Efflorescence and white staining on the chimney exterior. That white chalky powder is dissolved salts wicking through the brick. It isn’t cosmetic; it tells you water is moving through the masonry. We see it most on chimneys facing the afternoon sun in older western Olympia Heights neighborhoods, where the heating and cooling cycle pulls moisture through the brick again and again.
Pricing for Chimney Repair in Olympia Heights, FL
A chimney cap replacement in Olympia Heights runs $220 – $480. Chimney liner installation with a DuraFlex stainless system runs $1,200 – $3,800 depending on flue height, liner diameter, and whether we need to break out old clay tile first. Mortar repointing and tuckpointing run $35 – $55 per square foot of wall area, which for a typical exterior chimney means $600 – $1,400. Chimney waterproofing with a masonry-grade sealant usually falls between $450 and $900 for a full exterior application. Flashing repair runs $300 – $750, and a partial chimney rebuild, where we take down and rebuild a damaged crown or the top few courses of brick, can run $1,500 – $4,200. The price you’re quoted is the price on the invoice. We put it in writing before any work starts, and every repair carries the 365-Day Done Right Promise.

FAQs About Chimney Repair in Olympia Heights
The most common cause in Olympia Heights is a combination of high humidity, a rusted or stuck damper, and water entering through a failed chimney cap or cracked crown. Moisture sits in the ash bed and the flue, and the humid air keeps it from drying. We find the source by camera and fix the cap or damper first. The smell usually clears once the water stops entering. Call (786) 305-7861 to book an inspection and we’ll pinpoint the problem before recommending any repair.
No. Flaking brick, called spalling, means water has soaked into the brick and is breaking the masonry apart. On exterior-wall chimneys in Olympia Heights, where the bricks take afternoon sun and salt-laden wind, spalling usually signals deeper mortar deterioration behind the face. If enough brick face falls away, the chimney loses structural integrity and can start to lean. The repair is mortar repointing and, in bad cases, partial rebuilding. We can give you a written scope after a visual inspection.
Usually not; once a clay tile liner is cracked, you can’t reliably glue it back in a way that survives the heat. Systems like HeatShield can sometimes be used to seal and resurface a damaged clay liner from the inside, and we use it where the clay sections are still physically aligned. If the tiles have shifted or the joints are separated, the liner is finished and a stainless steel DuraFlex reline is the proper fix. We show you the camera footage either way, so you see what we’re seeing before you approve anything.
Plan on checking the cap every three to five years in Olympia Heights, and replacing it sooner if it’s a standard galvanized cap. Salt-laden air rusts galvanized steel quickly, and many caps in this area fail within five to eight years. Stainless steel caps from Gelco or Copperfield last significantly longer. If you see rust streaking on the chimney crown or water inside the firebox after a storm, schedule an inspection and we’ll tell you whether the cap can be saved or needs replacement. Estimates are free at (786) 305-7861.
Yes, if the liner is cracked or missing and the chimney vents a furnace, water heater, or other gas appliance. In many 1950s and 1960s Olympia Heights homes, the chimney is still connected to an atmospheric-draft water heater or an older furnace, and it runs every day whether you burn wood or not. A cracked liner in that system can leak carbon monoxide into the living space. If the chimney vents nothing at all, a cracked liner is less urgent but still lets water and humidity work on the masonry. We’ll scope it and tell you plainly whether the repair can wait. Call (786) 305-7861 to set up the camera inspection.
