Trusted Chimney Repair for Highlands Ranch Homeowners
Most chimney problems in Highlands Ranch start quietly. A cracked crown lets meltwater from a spring snow into the masonry, the freeze that follows opens the crack wider, and by the next heating season you have spalling brick and a flue that no longer seals. Our technicians have up to 15 years of experience finding that kind of damage and fixing it in the same visit, because we carry repair work as a core service rather than handing you a report and a phone number for someone else. We install professional-grade materials from HeatShield, DuraFlex, Olympia Chimney and Gelco, so the fix matches what the house actually needs. Same-day repair is often possible when you call early. Call (833) 749-6226 to set up a free estimate.
Chimney Cap Installation
Chimney cap installation is the single least expensive step you can take against water, animals and downdraft, and it’s usually done right after a sweep. A cap is a metal lid on a mesh frame that sits over the flue opening and keeps rain, snow, squirrels and nesting birds out while letting smoke escape. We fit stainless and powder-coated caps sized to the flue and the crown, sealed so wind doesn’t work them loose. Most installations run roughly $150 to $450 depending on the flue count and the cap style, and the written estimate sets the final price.
Why Cap Fit Matters on the Front Range
A cap that’s too small or loosely mounted rattles in a spring windstorm and can pull free. We measure the flue and the crown rather than reaching for the closest box size, so the cap sits square and stays put through hail and freeze-thaw cycles.
Caps for Multi-Flue Chimneys
Homes with a fireplace flue plus a furnace flue need a cap that covers the whole crown or two separate lids that don’t interfere. We plan the layout so each flue drafts on its own.

Chimney Cap Replacement
Chimney cap replacement is the fix when the existing cap is rusted through, bent, missing mesh or sitting crooked after a storm. A damaged cap stops doing its job quietly: rain gets in, animals find the gap, and the flue stays wet between burns. We lift the old cap, inspect the flue and crown underneath, then install a new cap matched to the opening, often from Olympia Chimney or Gelco, so the hardware lasts as long as the roof around it. Replacement typically runs $180 to $500 depending on whether the old cap was mortared in and how much of the crown needs attention first. The estimate you get in writing is the price you pay.
Rust, Bends and Storm Damage
A cap that’s lost its shape no longer sheds water where it should, and the drip lands on the crown. Catching that early keeps a small replacement from turning into masonry work.
Upgrading to a Better Grade
Stainless caps cost more upfront but hold up far better through years of hail and hard freezes than painted steel, which is why we lean toward stainless on roofs that will be climbed for years to come.
Chimney Liner Installation
Chimney liner installation is a full relining of the flue with a flexible stainless system when the existing liner is cracked, corroded, unlined or too large for the appliance. A compromised liner lets heat and carbon monoxide reach the framing and the living space, and it can’t be patched with sealant. We install DuraFlex flexible liner systems sized to the appliance and insulated where the code path requires it. What many homeowners don’t realize is that a damaged flue can often be resurfaced with HeatShield instead of fully relined, which saves money and avoids tearing into the chimney. Full relining typically runs $1,800 to $4,500 depending on height and liner diameter; resurfacing usually falls well under that. A camera inspection decides which one you actually need, and you see the footage yourself.
Resurfacing Versus Full Relining
HeatShield resurfacing rebuilds a deteriorating flue from the inside when the damage is moderate and the structure is sound. A full DuraFlex install is the right call when the liner is gone, badly cracked or never existed.
What the Camera Shows
Before any liner work we run a camera down the flue and record what it finds. You get a photo report showing the exact condition, so nothing gets recommended on trust alone.
Chimney Flashing Repair
Chimney flashing repair seals the joint where the chimney meets the roof, which is where most Highlands Ranch leaks actually start. Flashing is the layered metal and sealant that sheds water around the chimney base; when it lifts, rusts or loses its seal, water tracks down the masonry or into the attic. We reset and reseal existing flashing where it can be saved, and replace rusted or improperly installed flashing where it can’t, often using Copperfield components built to sit under shingles instead of over them. Typical flashing repair runs $300 to $700 depending on the roof pitch and how much of the existing material can stay. A leak caught early is a flashing job, not a roofing job.
Signs Water Is Getting In
Ceiling stains near the chimney, damp masonry after a storm or rust streaks on the flue pipe all point to flashing. The earlier you look, the cheaper the fix.
How Flashing Should Be Built
Proper flashing steps into the masonry or sits in a cut reglet so water can’t run behind it. We check that the layers overlap correctly, because glue alone won’t hold on this roof pitch.
Chimney Crown Repair
Chimney crown repair addresses the concrete slab on top of the chimney, the part that sheds water away from the masonry below. When the crown cracks, water gets into the brick and freeze-thaw cycles crack it further. We repair minor cracks with a flexible sealant and rebuild badly damaged crowns with a properly sloped pour so water runs off instead of pooling. Crown repair and rebuilding typically runs $350 to $900 depending on the chimney size and how much of the crown needs removal. Left alone, a cracked crown is the most common path to major masonry work, so it’s worth fixing while the repair is still small.
Cracks Versus a Full Rebuild
Hairline cracks can often be sealed and left to do their job. Wide cracks, crumbling concrete or a crown that slopes toward the flue usually mean a rebuild is the better value.
The Overhang That Protects the Brick
A well-built crown overhangs the masonry so dripping water clears the brick face. We shape the crown to shed past the edge rather than down the side.
Chimney Repair Companies
Chimney repair companies in the Highlands Ranch area range from sweep-only outfits that document problems to full-service companies that can fix them on the spot, and the difference matters when your chimney needs real work. If a company hands you an inspection report with no path to a fix, you’re left making calls. We repair what we find: sweeping, diagnosis and repair are all handled internally, so you’re not referred to a third party for liner, crown or flashing work. A diagnostic sweep and inspection, though not every chimney requires it, helps us find the real problem; we include camera inspection and a photo report, then quote the repair in writing. Call (833) 749-6226 and we can often book the sweep and the repair for the same visit.
What to Ask Before You Hire
Ask whether the company performs the repair itself or subcontracts it, and whether they install professional-grade liner systems or commodity hardware. The answer decides how much back-and-forth you’ll deal with.
Why In-House Repair Saves You Calls
When the same technician who inspects your flue can resurface it or install a liner, the problem gets resolved in one engagement. No re-quoting, no waiting on another contractor.
Chimney Masonry Repair
Chimney masonry repair restores the brick, mortar joints and upper structure when water intrusion has started to break the chimney down. Crumbling mortar, spalling brick faces, loose bricks near the crown and white efflorescence are the usual signs, and Highlands Ranch’s freeze-thaw swings push that damage along faster than a mild climate would. We repoint joints, replace spalled brick with matched units and rebuild the top courses when they’ve gone soft. The specific repair for your chimney depends on what the inspection shows; we recommend a camera inspection and a written scope before masonry work, so you see why a section needs replacing rather than repointing. Call (833) 749-6226; estimates are free.
Repointing Versus Rebuilding
When the mortar has receded but the brick is still sound, repointing restores the joint. When the brick faces have spalled or the top courses are loose, partial rebuilding is the durable fix.
Stopping Water at the Source
Masonry repair lasts only if the water that caused the damage is cut off first. We look at the crown, flashing and cap together so the repair isn’t undone by a leak above it.
Brands We Service
We install and work with professional-grade materials, starting with DuraFlex, which supplies the flexible stainless liner systems we use for complete relining. DuraFlex liners are made to flex down an offset flue without kinking, and we size and insulate them to the appliance so the install holds up over time rather than just passing the first inspection. We also work with HeatShield, the ceramic resurfacing product that restores a deteriorating flue from the inside, and it’s the reason many liner replacements can be handled as a resurfacing instead. Our technicians have up to 15 years of experience reading what each brand of liner and cap is telling them.
On the hardware side, we install caps and components from Olympia Chimney, Gelco and Copperfield, and we match the part to the chimney rather than grabbing whatever box is closest. If you already have Olympia Chimney or Copperfield components in place, we can service and repair them. Whether you have Gelco, Famco, or any other make, we can help.

- Water stains near the chimney or on the ceiling. A stain usually means flashing or crown damage is letting water in. It rarely stops on its own, and masonry damage gets more expensive the longer water runs.
- White crusty deposits on exterior brick. That’s efflorescence, a sign moisture is moving through the masonry. It points to a leak above that needs sealing before the brick spalls.
- Cracked or crumbling crown or mortar. Visible cracks in the concrete crown or receding mortar joints mean freeze-thaw is breaking the chimney down. Catching it while it’s repointing keeps it from becoming rebuilding.
- Rust flakes or corrosion on the flue or damper. Rust inside the firebox or on the liner is a sign of ongoing moisture. A compromised liner can let heat reach the framing, so it’s worth a camera inspection.
- Pieces of masonry or cap on the roof. Loose brick, mortar or a shifted cap on the roof means something above is failing. Have it inspected before the next snow load works it loose.
Our Process, Step by Step
- 1
Book a visit and confirm what you’re seeing. We ask about leaks, drafts, rust and when you last burned, then get a sweep and inspection on the calendar. If your problem is urgent, call so we can work it in.
- 2
Clean and inspect. We sweep the flue and run a camera down it, checking the liner, damper, smoke chamber, crown, flashing and cap. Photos go into a report you can keep.
- 3
Show you the evidence. We walk you through the camera footage and photos so you can see the condition for yourself. Nothing gets recommended without evidence you can look at, and we tell you plainly when work can safely wait.
- 4
Quote the repair in writing. The written estimate covers exactly what’s needed and the materials we’ll use, such as a HeatShield resurface, a DuraFlex liner or a crown rebuild. The estimate sets the price.
- 5
Repair and leave it tight. We complete the work, clear the roof and run a check before we go. If a sweep found the problem, we’re set up to fix it without a second appointment.
