Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Key Biscayne, FL
Key Biscayne homes need a different kind of chimney care than almost anywhere else in South Florida. The island’s oceanfront air is saturated with salt, and it works into mortar joints, metal dampers, and flue liners year-round, even in homes where the fireplace hasn’t been lit in years. Most of the housing stock here dates from the 1950s through the 1970s, with masonry chimneys that were built for occasional use and now face decades of wind-driven spray. We’re Ashby Chimney Miami, and if you need a chimney company in Key Biscayne, call us at (850) 787-8597. We’ll give you a written price before any work starts, and we’ll show you what we find with a camera before you spend a dollar on repairs.
Why Key Biscayne Homes Are Different
Salt is the main troublemaker on this island. It sits in the air, settles on crowns and caps, and gets pulled into porous brick and mortar with every rain. Over time, salt crystals expand inside the masonry, which is why we see spalling brick and crumbling crowns on Key Biscayne chimneys more often than inland. The oceanfront sections, particularly along Ocean Drive and Harbor Drive, take the worst of it, but even homes on the bay side get steady humidity and occasional storm surge. Homes in Key Biscayne’s original 1950s subdivisions were built with clay flue liners, and those liners crack and flake after a few decades of salt exposure. We also find rusted dampers frequently, sometimes so corroded they won’t budge, because the warm climate lets moisture sit in the firebox for months without being baked out by regular fires. In newer luxury builds, the issue is often the opposite: a fireplace that was never properly broken in, with moisture trapped in the masonry from day one.
Styles & brands we work with
Our Main Key Biscayne Services
Most calls we get from Key Biscayne homeowners start with one of two things: a fireplace that hasn’t been checked in years, or a suspicion that the chimney is letting water in. Here’s what we do about both.
Chimney Sweep in Key Biscayne
A sweep here is less about heavy creosote buildup and more about clearing what the island’s birds and weather leave behind. Key Biscayne’s nesting season brings birds into uncapped flues, and we regularly pull out nests, palm fronds, and debris that block the flue. Salt air also leaves a fine, corrosive dust that settles on dampers and smoke shelves. When we sweep a Key Biscayne home, we protect the interior with drop cloths, use HEPA-filtered equipment, and leave the firebox cleaner than we found it. It’s the same process we use for every job, and it’s spelled out on our Chimney Sweep in Key Biscayne page.
Chimney Inspection in Key Biscayne
Given the salt and humidity here, we recommend an inspection even for homeowners who haven’t used their fireplace in years. A camera inspection will show exactly what’s happening inside the flue, whether that’s spalling clay tiles, a rust-thinned damper, or moisture staining in the smoke chamber. We’ll walk you through the footage and tell you plainly what can wait and what needs attention now. The full details, including what we look for and how long it takes, are on our Chimney Inspection in Key Biscayne page.
Fireplace Repair in Key Biscayne
Most repairs on the island come down to water damage: a cracked crown, a failed cap, or mortar joints that have turned to powder from years of salt. We repair these with materials built for coastal conditions, and we put the warranty in writing on every job. If a covered repair fails inside the guarantee period, we come back and fix it at no charge. That’s our 365-Day Done Right Promise, and it applies to every repair we do. You can see the kinds of damage we tackle and how we price it on our Fireplace Repair in Key Biscayne page.

What Key Biscayne Customers Say
"The amount of creosote they pulled out was scary. He said we were overdue and explained the fire risk without being dramatic about it. Clean, careful, left the hearth spotless."
- Caroline Webb"The damper was rusted shut and we couldn't use the fireplace. He freed it up, swept everything, and now we actually use the thing. Priced it before he started."
- Georgia Lemmon"Had them out for the yearly sweep before we start burning. He put down a drop cloth, swept it clean, and actually showed me the inside of the flue on a little camera. No mess, no surprises on the bill."
- Bill Prentice
