I’m glad you’re here, because I’d love to tell you how we handle chimney repair around Denver. A chimney that’s falling apart isn’t just an eyesore — it lets water in, drafts smoke back into your living room, and on a bad day it can start a fire. So let me walk you through the repairs we do, what they cost, and how we think about each one here in the Mile High City.
After 20-plus years on Denver rooftops, I’ve learned that no two chimneys fail the same way. A 1920s brick stack in Five Points has different problems than a newer chase cover in the suburbs. Below is a straight look at what we fix and why it matters.
Chimney Repair Services in Denver
Chimney repair in Denver covers a lot of ground, from a small crown crack to a full masonry rebuild, and the right fix depends on where the damage starts. The most common spot we get called about is the top, so let’s start there.
Chimney Crown Repair: Stop Water Damage at the Top
Water damage almost always starts at the top of your chimney. The chimney crown is the concrete cap that sheds rain away from the brick and flue below it. When it cracks, water gets in and the trouble spreads downward fast. Here’s what we charge to put a crown right:
- Minor crack repairs: Starting at $300
- Major crown rebuilding: Ranging from $800-$1,500
- Crown sealing: Between $200-$400
The work goes like this. First we chip out the damaged or crumbling material. Then we reshape the crown so rain runs off instead of pooling, and we finish with a flexible, waterproof sealant that moves a little when the concrete expands and contracts. For homeowners in neighborhoods like Cherry Creek (80206) and Washington Park (80209), where the look of the house matters, we shape and finish the crown so it sits cleanly against the rest of the masonry and doesn’t stand out.
One recent client in Park Hill (80207) had real water leakage from cracks in the crown. The moisture had already worked its way into their chimney chase and started rusting the metal inside. We sealed the crown, stopped the water at the source, and saved them from a much bigger interior repair down the road. Minor patch or full rebuild, we’ll tell you straight which one you actually need.
Nine times out of ten, when somebody calls me about a leak by the fireplace, the real culprit is a cracked crown up top — not the roof. I’d rather seal a $300 crown today than rebuild a $6,000 firebox after two winters of water getting in. Fix the top, and you protect everything underneath it.

Flue Liner Repair and Replacement: Safety and Efficiency
A damaged flue liner is one of the more serious problems we run into. The liner is what keeps heat and combustion gases inside the chimney and away from the wood framing of your house. When it cracks, you can get poor draft, smoke in the room, and a real fire risk. Our flue liner repair and replacement work matters most in older homes around Capitol Hill (80203) and Baker (80204), where a lot of chimneys still run on original clay tile. Here’s the range:
- Clay tile flue repair: $250-$800
- Stainless steel liner installation: $2,500-$5,000 (depends on chimney height and complexity)
- Cast-in-place liner: $2,800-$7,000
On older chimneys with cracked or flaking clay tile, we usually recommend a full stainless steel liner instead of patching. Patching buys you a year or two; a stainless liner is rated to last and gives you a clean, code-correct system you don’t have to think about again.
Take our recent job on Capitol Hill. Laura had lived in a gorgeous Victorian for years, and lately her fireplace was drafting badly and pushing smoke into the living room. When we ran the camera up the flue, the clay tile liner had cracked in several places and was partly blocking the path. Given the age of the home, we put in a full stainless steel liner installation. The job went smoothly, and Laura’s fireplace draws clean now — no more smoke, no more worrying about what’s going on behind the brick.
Tuckpointing and Masonry Repair in Denver
Brick and mortar don’t last forever, and on older homes in neighborhoods like LoDo (80202) and Five Points (80205), the mortar joints are usually the first thing to go. Our masons handle tuckpointing and brickwork repair, keeping the chimney solid while holding onto the historic character people bought the house for. Here’s the pricing:
- Tuckpointing: $10-$25 per square foot
- Brick replacement: $20-$40 per brick
- Complete chimney rebuild: $4,000-$15,000
Matching the mortar is half the job on an old house. Get the color or texture wrong and the repair sticks out like a patch. We recently worked on a 1920s home in Five Points where the chimney mortar was crumbling and a few bricks had spalled. The owner, James, wanted the original look kept. We tuckpointed the joints, mixed mortar to match the old color, and swapped the damaged bricks. When we were done, the chimney blended right back into the historic brickwork and you’d never know it had been touched.
People think tuckpointing is just cosmetic. It’s not. Those mortar joints are what hold the whole stack together, and once water gets behind a soft joint, our freeze-thaw winters here pry the brick apart a little more every night. On these older Denver homes, repointing at the right time is the cheapest insurance you can buy.

Chimney Cap Installation and Repair
A chimney cap does a lot for a small piece of metal. It keeps rain out of the flue, blocks leaves and debris, and stops birds and squirrels from moving in. We install and repair caps to keep all three problems out of your chimney. Here’s what they run:
- Standard chimney cap installation: $150-$400
- Custom copper chimney cap: $500-$1,500
- Multi-flue cap installation: $300-$600
For homes near active wildlife, like Highlands (80211) or Sloan’s Lake (80212), we go with heavy-duty animal-resistant caps. Recently a family in Highlands had squirrels nesting right in their chimney. We fitted a sturdy stainless steel cap with a mesh screen, and that was the end of the squirrels — plus the cap now keeps water out of the flue, which adds years to the whole system.
Smoke Chamber Parging
Smoke chamber parging smooths out the rough area just above the firebox so smoke moves up and out instead of swirling and stalling. A smooth chamber drafts better and gives creosote buildup far fewer rough spots to grab onto, which makes the whole chimney safer to use. Here’s the cost:
- Smoke chamber parging: $1,000-$2,500
- Chamber restoration: $2,500-$4,000
This one comes up a lot on older homes in Congress Park (80206) and Park Hill (80207), where the smoke chambers were built rough and have deteriorated over the decades. We recently helped a homeowner in Park Hill whose rough chamber was killing the draft and packing on creosote fast. We parged and smoothed the surface, and afterward their chimney ran cleaner, drafted better, and was a lot safer to light up.
Firebox Repair
The firebox is where the fire actually burns, so it takes the most heat and wears out from the inside. We keep it safe and solid with these repairs:
- Minor mortar joint repair: $200-$500
- Firebox panel replacement: $800-$1,500
- Complete firebox rebuild: $2,500-$5,000
For homes in upscale areas like Cherry Hills Village or Greenwood Village, we also build custom fireboxes designed to fit high-end interiors, so the repair looks like it belongs in the room.
Additional Services
- Chimney waterproofing: $500-$1,000
- Damper replacement: $300-$500
- Chase cover installation: $400-$1,000
These smaller jobs matter more than they sound, especially in our climate. Waterproofing keeps melting snow from soaking into the brick. A working damper stops your heated air from escaping up the flue all winter. And a solid chase cover keeps water out of the top of a factory-built chimney before it ever reaches the framing.

- Flue Liner Repair and Replacement: We protect your chimney from $250 for minor repairs up to $5,000 for full replacements.

How Our Chimney Repair Process Works
We don’t guess, and we don’t sell you repairs you don’t need. Here’s the order we work in on a typical repair call:
- We inspect first. Before we quote a dollar, we look the whole chimney over, inside and out, and run a camera up the flue when it’s warranted.
- We show you what we found. You get plain photos and a clear explanation, not jargon. You’ll see the crack, the cracked tile, or the soft mortar with your own eyes.
- We give you a written, itemized price. You’ll know what each part costs and where the number comes from before we start.
- We do the work. Crown, liner, masonry, cap, or firebox — our crew handles it with the right materials for a Denver winter.
- We clean up and check our work. We test the draft, confirm the repair, and leave your home as clean as we found it.
Warning Signs Your Chimney Needs Repair
Most chimney problems give you a heads-up before they turn into an emergency. Call us if you notice any of these:
- Water stains on the ceiling or wall near the chimney
- Smoke pushing back into the room when you light a fire
- Bits of brick, mortar, or rust showing up in the firebox or on the roof
- A strong, smoky smell even when the fireplace is cold
- White, chalky staining on the outside brick (that’s efflorescence, a moisture sign)
- A rusty or sagging damper, or a firebox panel that’s cracking apart
None of these fix themselves, and our freeze-thaw winters make every one of them worse the longer you wait. Catching them early is almost always the cheaper road.

A Denver Success Story
Last month, we helped the Johnson family in the Washington Park neighborhood. They’d spotted some moisture in their fireplace after a heavy rain. When we inspected, the chimney crown was badly cracked and letting water seep right in. We repaired the crown, set a new chimney cap, and applied a water repellent to head off future leaks. As Mrs. Johnson put it, “Adam and his team were fantastic! They explained everything clearly and had our chimney fixed in no time. We feel so much safer using our fireplace now.”
The Surprise Discovery in Washington Park
Emily and David Thompson had just moved into their 1950s bungalow in Washington Park when they decided to inspect their chimney before using the fireplace. They were shocked by what we found.
“We had no idea our chimney was in such bad shape,” Emily recalled. “Adam’s team discovered that the flu liner was completely deteriorated. They explained everything clearly and installed a new stainless steel liner. We’re so grateful they caught this before we had a serious problem.”
The Thompsons also opted for a chimney cap installation to prevent future issues.
Cost of Service: $3,800 for flue liner replacement and chimney cap installation.
The Eco-Conscious Upgrade in Cherry Creek
A long-time Cherry Creek resident, Dr. Aisha Patel, contacted us about converting her wood-burning fireplace to a more environmentally friendly option.
“I loved my fireplace, but I was concerned about air quality and efficiency,” Dr. Patel explained. “Adam suggested a high-efficiency gas insert. They handled everything from the chimney inspection to the installation. Now I have a beautiful, clean-burning fireplace that I can control with a remote!”
Cost of Service: $4,200 for a chimney inspection, gas line installation, and gas insert installation.
The Historic Preservation in Five Points
Marcus and Julia Reeves own a beautifully restored 1927 Craftsman home in Five Points. They called us when they noticed water stains on their living room ceiling near the chimney.
“We were worried about potential damage to our home’s original features,” Marcus said. “Adam’s team found that our chimney crown was severely cracked. They repaired it and also repointed some of the upper brickwork. Their attention to detail in matching the original mortar was impressive.”
Cost of Service: $2,800 for chimney crown repair and partial repointing.
The Mountain Home Maintenance in Genesee
The Andersen family has a vacation home in Genesee that they visit frequently during ski season. After noticing a smoky smell in the house, they called us for an inspection.
“We use our fireplace a lot during the winter, so we wanted to make sure everything was safe,” Lisa Andersen explained. “Adam’s team found a significant creosote buildup and some minor cracks in the firebox. They did a thorough cleaning and repair. Our fireplace draws beautifully, and we feel much safer using it.”
Cost of Service: $1,200 for chimney sweep, creosote removal, and minor firebox repair.

Denver Chimney Repair FAQ
How much does chimney repair cost in Denver?
It depends on the job. Small fixes like a crown crack or a damper swap start around $200–$300. Mid-range work like flue repair or tuckpointing runs into the hundreds or low thousands. Big jobs like a full stainless liner or a masonry rebuild can run from a few thousand up to $15,000 on a complete rebuild. We give you an itemized price after we inspect, so you’re never guessing.
How often should I have my chimney inspected?
Once a year, before you start burning for the season. A yearly inspection catches small cracks and creosote before they turn into a leak, a draft problem, or a fire hazard. If you burn a lot of wood through a Colorado winter, that annual check is even more worth it.
Can you repair a chimney in the winter?
Often, yes. Interior work like liner installation and many firebox repairs go fine in cold weather. Some masonry and crown work needs temperatures above a certain point to cure right, so we’ll tell you honestly if a particular repair is better scheduled for a warmer, drier stretch.
Why does my fireplace smell smoky when it’s not in use?
That smell usually means creosote buildup in the flue, sometimes paired with moisture and a draft issue. A sweep plus a look at the cap and liner normally clears it up. It’s also a sign worth acting on, since heavy creosote is the main fuel for a chimney fire.
Please Don’t Wait Until It’s Too Late
A little upkeep now beats a big repair later. If you’ve noticed any of the warning signs above, or it’s simply been a while since your last inspection, call (720) 207-9232 or schedule an appointment. You can also learn more about safe wood burning and indoor air quality through the EPA’s Burn Wise program.
Don’t let a chimney problem put your home at risk. For chimney repair anywhere in Denver, Adam Chimney Sweep has you covered. We’re not just fixing chimneys; we’re making homes safer, one fireplace at a time.
