Call (844) 803-1545

We’ve been working on Denver chimneys since 1984. That means we’ve repointed mortar on Capitol Hill Victorians that predate the Model T, rebuilt crowns on Baker bungalows that have survived a century of Front Range weather, and diagnosed flue damage in Curtis Park row homes where the original 1920s clay tiles are still in place. Denver’s altitude, sunshine, and violent temperature swings create repair patterns you won’t find in Kansas City or even Fort Collins. We know what to look for because we’ve seen it hundreds of times.

Why Hearthstone Chimney Co. Is Denver’s Preferred Chimney Repair Company

Forty-two years in this trade teaches you that a chimney repair is only as good as the person standing behind it. Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. values: Krafted right, Every time, Your home first, Standing behind it.

Every inspection we perform in Denver ends with photos you can see and a plain-English verdict. Our Level-2 camera inspections document what Chimney Cleaning & Sweep - Denver standard sweeps miss, especially in the pre-WWII housing stock that dominates central Denver. In neighborhoods like Five Points and Curtis Park, we’ve found original clay flue tiles that passed a rod sweep but showed dangerous joint separation under camera - gaps venting combustion gases into wall cavities that a less thorough inspection would have left hidden.

Our technicians are background-checked, uniformed, and arrive with the materials to finish most repairs same-day. No waiting on parts, no return trips, no surprises on the bill. The number on your estimate is the number on your invoice. And when you call (844) 803-1545, a live person answers - not a voicemail, not a callback queue, not an app.

Our Chimney Repair Services in Denver

Mortar Repointing

Denver’s semi-arid climate punishes mortar joints harder than wetter cities. Those 40-50°F single-day temperature swings in spring and fall - routine here, extraordinary almost anywhere else - drive repeated freeze-thaw cycles that grind away the binding material between your bricks. In Capitol Hill and Congress Park, we regularly repoint chimneys on homes built between 1890 and 1940 where the original lime mortar has simply weathered out after eight decades of this stress. We grind out the damaged joint to proper depth and repack with professional-grade mortar matched to your chimney’s era and exposure.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - accelerates dramatically in Denver’s climate. The combination of intense UV, rapid snowmelt, and same-day refreezing in chimney crowns and caps creates moisture penetration that destroys brick from the inside out. We’ve replaced spalled brick on Washington Park bungalows where the south-facing exposure had deteriorated so badly that the structural integrity of the chimney stack was compromised. We source matching brick when possible and rebuild with proper drainage to break the cycle.

Chimney Waterproofing

Water is a chimney’s enemy everywhere, but Denver’s weather pattern is uniquely destructive: 300-plus days of sunshine mean snowmelt happens fast, then temperatures drop overnight and that moisture refreezes in the masonry. Standard waterproofing products formulated for wetter climates often fail here because they don’t account for this rapid cycling. We apply breathable, vapor-permeable sealers from HeatShield and Copperfield that let moisture escape while blocking liquid penetration - critical for Denver’s thermal stress environment. A typical waterproofing treatment on a Denver single-flue chimney runs $380-$650 and carries our 90-Day Done Right Promise.

Flashing Repair

Chimney flashing takes a beating in Denver’s wind and hail corridor. The step flashing where your chimney penetrates the roofline is a common leak point, and repairs left unaddressed rot roof decking and ceiling joists. We repair and replace flashing on all roof types common in Denver’s neighborhoods - the steep pitches of Victorian roofs in Baker, the low slopes of Craftsman additions in Congress Park, the composite and tile systems found throughout 80203-80206. We fabricate custom flashing when needed and seal with professional-grade compounds that flex through Denver’s temperature extremes without cracking.

For chimney cap and crown work specifically, we also offer Chimney Cap & Crown in Denver as a focused service with its own inspection protocol.

Trusted Brands We Service in Denver

We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Olympia Chimney, Famco, and Copperfield - brands that hold up to Denver’s altitude-driven thermal stress and UV exposure. Because we stock these materials locally, we’re not waiting on a shipment from out of state while your chimney continues to deteriorate. When we inspect your chimney in the morning, we can often complete the repair that same afternoon. That’s how most of our Denver jobs get done in a single visit.

Common Chimney Repair Problems We See in Denver Homes

• Crown cracks from rapid freeze-thaw. Denver’s same-day snowmelt-and-refreeze pattern destroys concrete crowns faster than steady cold climates. We see this on nearly every pre-1980 chimney in 80204 and 80205.
• Shifted clay flue tiles in century-old housing. The original 1910s-1920s clay liners in Curtis Park and Five Points have separated at joints after a hundred years of thermal cycling. A sweep rod passes; combustion gases don’t.
• Spalled brick on south and west exposures. Intense Front Range UV accelerates surface deterioration. We replace spalled brick and address the moisture source so it stops.
• Failed flashing from hail and wind. Denver sits in a hail corridor. We’ve resealed and replaced flashing after storms that lifted corners and created channels straight into roof assemblies.
