Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Cap & Crown Across Knoxville
Chimney cap and crown work in Knoxville isn’t a seasonal afterthought, it’s the difference between a fireplace that drafts cleanly on a January night and one that pours smoke back into a Sequoyah Hills living room. The bowl of the Tennessee Valley traps cold air against chimneys in ways flatter cities never see, and that pressure problem puts real stress on every cap and crown from Fourth & Gill to South Knoxville. Our crews work the entire Knoxville metro, including Oak Ridge, Maryville, and Morristown, and we carry the Famco, Copperfield, and Gelco materials local masonry systems actually need. If your crown is spalling or your cap is missing, call (980) 580-8641 and we’ll get a written price in your hands before anyone touches a trowel.
Why Emberly Chimney Cleaners Is Knoxville’s Preferred Chimney Cap & Crown Company
Knoxville homeowners call us because we show up with a camera, not a flashlight. Every Chimney Cap & Crown visit includes an NFPA 211 Level 2 inspection with a camera scan of the flue, and you walk away with photos of exactly what we found. That’s Clause 4 of the Haven Standard, and we’ve kept that photographic record on every job since 2009, more than 38,000 inspections deep.
Our crews know the difference between a 1920s brick chimney in Old North Knoxville and a zero-clearance prefab fireplace in an East Knoxville ranch, because they’ve worked both hundreds of times. Corrine Halstead runs our team, and she’s the person who reviews the camera footage before any recommendation reaches you. We don’t guess. We document. We also answer the phone 24 hours a day with a live person, not a voicemail, and our techs arrive background-checked and in uniform, with a text when they’re on the way.
What earns repeat calls from Knoxville customers isn’t longevity or slogans. It’s the written price, written scope, and written warranty delivered before work starts. Clause 1 of the Haven Standard. No exceptions, no “call for a quote.” The price is on the page or in your hand before you decide anything.
Our Chimney Cap & Crown Services in Knoxville
Cap Installation
A proper cap on a Knoxville chimney does more than keep rain out. The valley’s inversions push smoke back down flues that would draft adequately in Nashville or Chattanooga, and a correctly sized cap with the right mesh spacing actually stabilizes that draft. We stock Famco and Copperfield caps in the sizes Knoxville’s older masonry flues actually use, including the oddball dimensions common in 1930s Parkridge homes. Most installations run $350 to $650 depending on flue size and access.
Cap Replacement
If your cap has rusted through or blown off in one of Knoxville’s recurring winter ice storms, we replace it with stainless steel hardware rated for the freeze-thaw abuse this valley delivers. Rust streaks down a chimney crown are the first sign. A standard replacement on a single-flue masonry chimney in Knoxville typically runs $275 to $500. We’ll show you the failed cap before it comes off, and photograph the new one after it’s set.
Crown Repair
Knoxville’s wet winters and hard freezes spall crowns faster than almost any market we work. When water gets behind a cracked crown, it freezes, expands, and pops the mortar bed loose, then drips into the flue all spring. On a Fourth & Gill home this year, our crew found a crown so badly spalled that water had been running behind the clay tile liner for seasons, turning routine creosote into third-degree glaze inside a wood stove firebox that had been banked nightly with green hardwood. We removed the failed crown, rebuilt the mortar bed, and sealed everything under a reinforced form. Crown repairs in Knoxville run $450 to $900 depending on how much of the original crown is salvageable.
Crown Coating
When the crown is structurally sound but losing its surface, we apply a Gelco crown coat instead of tearing it out. This is the right call for hundreds of Knoxville chimneys with minor surface cracking, and it’s a legitimate long-term fix when the underlying mortar is intact. The coating bonds to the existing concrete and sheds water far better than bare mortar. Typical crown coating in Knoxville runs $300 to $550, and we photograph the surface before and after so you can see exactly what was treated.
Multi-Flue Cap
Older Knoxville homes often have two or three flues sharing one chimney, and a single-flue cap leaves the others open to rain, squirrels, and the valley’s damp air. A custom multi-flue cap from Copperfield or Famco covers the entire crown and includes a spark arrestor sized for the draft reversals that come with basin inversions. On a Multi-flue cap for a two-flue chimney in Knoxville, expect to pay $550 to $900, including the Level 2 inspection and photo documentation.
Custom Cap
Some Knoxville chimneys don’t fit a stock cap. Offset flues, oversized openings, or decorative brickwork on a Sequoyah Hills chimney sometimes require a fabricated cap, and we measure, order, and install those from Copperfield. Custom caps in Knoxville typically run $700 to $1,200 depending on size and material. The process includes the inspection, the measurements, the fabrication, and the installation, all documented in writing and photo.

Common Chimney Cap & Crown Problems We See in Knoxville Homes
- Freeze-thaw spalling on original 1920s to 1940s brick crowns in Old North Knoxville. These crowns were poured when the homes were built, and after 80 to 100 years of Knoxville ice storms, the surface pops loose and lets water into the flue. Water behind the liner accelerates creosote adhesion in wood-stove systems that run as primary heat.
- Uncapped flues on zero-clearance prefab fireplaces in East Knoxville ranch homes. These systems were built without a cap in the original installation, and animals plus moist valley air get into the flue liner between burns. The result is first-degree creosote that hardens before the next Level 1 inspection, and a cap becomes mandatory before we can certify the system.
- Third-degree tar glaze from overnight “banking” of unseasoned hardwood in South Knoxville hill homes. The practice of loading a wood stove with green or mixed hardwood and closing the damper overnight produces a gummy, glazed creosote that reaches the smoke chamber and crown. It has to be removed before a cap can be properly sealed, or you’re just covering a fire hazard.
- Draft reversal caused by Knoxville’s temperature inversions. The bowl-shaped valley traps cold air against chimneys, and that pressure difference pushes smoke back down flues that would draft fine in open terrain. A properly sized cap with the right mesh diameter stabilizes the draft instead of fighting it.

FAQs - Chimney Cap & Crown in Knoxville
Knoxville’s freeze-thaw cycle is more aggressive than Nashville’s because the valley traps cold, moist air against chimney exteriors, and that water freezes inside the crown’s surface pores, then expands. Nashville’s more open terrain lets chimneys dry out between storms. A Knoxville crown needs sealing or coating earlier and more often. Call (980) 580-8641 and we’ll show you the spalling on camera before you spend a dollar.
Yes, if you have multiple flues in one chimney. The unused flue is the problem: uncapped, it admits rain, squirrels, and damp valley air that hardens into creosote even when you rarely burn. A multi-flue cap covers the entire crown, including the flues you don’t use. Most Fourth & Gill homes with two or three flues should have one.
No. The glaze you’re seeing is third-degree creosote from burning green or unseasoned hardwood, especially overnight banked fires. That glaze has to be removed mechanically before any cap is installed, or you’re sealing a fire hazard under a new lid. We’ll remove the glaze, confirm the liner condition with the camera, then install the correctly sized cap. Call (980) 580-8641 to get the process started with a written quote.
The valley’s inversions trap cold air against the chimney and create downward pressure that reverses draft, especially on still, cold nights. A cap with the wrong mesh size or a poorly fitted crown seal makes that draft reversal worse, not better. We size caps for the stack effect and the inversion pressure pattern Knoxville actually experiences, which is why a generic hardware-store cap often fails to fix the problem.
Yes. The crown is the roof of your chimney, and a cracked crown leaks water into the flue, the smoke chamber, and eventually the masonry itself, whether or not you ever light another fire. By the time you see water stains on a ceiling below, the liner is often already damaged. Our Level 2 inspection includes the crown and the camera scan, and you’ll see the photos before you decide. Call (980) 580-8641 to schedule.
