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.

AfterTrusted Chimney Cap & Crown for Denver Homeowners
Our Chimney Cap & Crown cost guide shows Denver work typically runs $280-$1,850 depending on whether you’re sealing a hairline crack or replacing a full concrete crown with a stainless cap. We’re Level Two Chimney Denver, and we’ve inspected more than 38,000 chimneys since 2009 - every one with a camera down the flue, a written price before any work started, and a documented photo record when it was done. Call us at (720) 674-7312 for a free estimate with real numbers you can compare.
Denver’s freeze-thaw cycles are brutal on chimney crowns. Water gets into hairline cracks in October, expands when temperatures drop below 20°F in January, and by March you’ve got spalling concrete, rusted flue liners, and water stains on your ceiling. We’ve documented this exact progression in Park Hill, Highlands Ranch, and Wash Park homes - always with the same root cause: a Denver Chimney Cap & Crown that was left too long without repair.
Our crews are background-checked, uniformed, and licensed. You get a named technician, a text when they’re on the way, and a written scope, written price, and written warranty before anyone touches your chimney. That’s Haven Standard Clause 1: “Have it in writing.” No exceptions.
What Our Chimney Cap & Crown Service Includes
Cap Installation
A chimney cap is a metal cover that sits over your flue termination, keeping rain, snow, and animals out while letting smoke escape. In Denver, where spring hail and winter snow load are real factors, a properly sized cap prevents the water intrusion that destroys flue liners from the top down. We measure your flue count, flue shape, and chimney dimensions on-site, then source stainless steel or copper caps from Gelco or Olympia Chimney through our Haven buying network - no guesswork on fit, and no markup on materials we don’t specify in writing.
Cap Replacement
Most caps we remove in Denver have been on 15-25 years and show rust-through at the corners, screen separation, or blow-off from wind gusts that hit 60+ mph along the Front Range. We don’t just swap like-for-like. We inspect the flue tile condition beneath the old cap, document it with photos under Haven Standard Clause 4, and note whether the new cap needs a deeper skirt or wider flange to cover crown deterioration that’s already started. If the crown is compromised, we tell you before quoting cap-only work.
Crown Repair
The crown is the concrete slab that tops your masonry chimney, sloped to shed water away from the flue. When we find crown cracks in Denver homes - common in Baker, Berkeley, and Montclair neighborhoods with 1940s-1970s brick construction - we first determine if the steel reinforcement mesh inside has rusted and expanded. Surface cracks get routed, cleaned, and sealed with a flexible crown coating. Deeper delamination or rebar rust means partial or full crown rebuild, and we show you the difference on camera before you decide.
Crown Coating
Crown coating is a specialized elastomeric sealant applied to sound but weathered concrete crowns, not a fix for structural failure. We use it when the crown has minor cracking, slight surface spalling, or porosity that’s letting water migrate toward the flue but the underlying concrete and reinforcement are still intact. In Denver’s high-UV environment, we specify coatings rated for thermal cycling and apply them only after pressure-washing and priming - a two-day process that costs less than rebuild but only works on crowns that pass our inspection.
Multi-Flue Cap
Multi-flue caps cover two or more flues on a single chimney, common in Denver duplexes, Victorian conversions in Capitol Hill, and homes with separate fireplace and furnace flues. The critical detail is coverage: the cap must extend past the chimney edge by at least 5 inches on all sides to protect the crown from direct precipitation. We fabricate and install multi-flue caps with integrated drip edges and mesh screening, sized to your chimney’s exact footprint, sourced through DuraFlex or custom-fabricated from measured drawings.
Custom Cap
Custom caps solve fit problems on oversized flues, decorative chimney pots, or heritage masonry where standard sizes don’t work. We’ve built custom solutions for Denver Square homes in Cheesman Park, mid-century moderns in Krisana Park with unusual chimney profiles, and historic properties in Curtis Park with original terra cotta flue extensions. Every custom cap starts with field measurements, a photo of the existing termination, and a written quote with a fabrication drawing you approve before we cut metal.

Brands We Service for Chimney Cap & Crown
We source and install caps and crown materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney through Haven’s buying network. DuraFlex stainless components handle Denver’s temperature swings without the thermal fatigue we see in lesser alloys - we’ve installed hundreds of their multi-flue and single-flue caps in Aurora, Lakewood, and Westminster with zero callback for fit. HeatShield’s crown repair and resurfacing products bond to prepared concrete at the molecular level, which matters when you’re sealing a crown that’s seen 20 years of Front Range weather cycling between 90°F summer days and sub-zero winter nights.
Gelco’s galvanized and stainless cap lines cover the standard flue sizes we encounter in Denver’s post-war housing stock, and we stock common sizes for same-visit installation when the crown beneath is sound. Olympia Chimney’s European-style copper caps and custom-fabrication options serve the higher-end installations we do in Cherry Hills Village, Hilltop, and Crestmoor. Whether you have one of these brands or any other make - including no-name caps installed by previous owners - we inspect, document, and quote repair or replacement with written pricing before work begins.

AfterSigns You Need Chimney Cap & Crown Right Now
- Water stains on your ceiling near the chimney breast. This means water has already penetrated the crown or cap, run down the flue liner, and found a gap in the attic framing or interior masonry. In Denver, where attic temperatures fluctuate wildly between day and night, that moisture condenses and spreads. We trace the entry point with a camera inspection and show you the exact path.
- Visible cracks or flaking on the crown surface. Concrete crowns should shed water with a smooth, sloped surface. Spalling - surface flaking caused by freeze-thaw - accelerates exponentially once it starts. We’ve measured 1/16-inch cracks become 1/2-inch gaps in two Denver winters when left unsealed.
- Rust stains running down the chimney exterior. Orange or brown streaks on brick mean the cap is leaking or missing, and water is rusting the flue liner, damper frame, or firebox components inside. In homes with galvanized flue liners, this is often the first visible warning of liner failure.
- Animals or nesting debris in the fireplace. Squirrels, raccoons, and starlings enter through uncapped flues. A cap with intact mesh prevents this. If you’re hearing scratching or finding twigs, the cap is gone, damaged, or was never installed - and the open flue is also letting in rain and snow.
- The cap is missing, tilted, or has visible blow-off damage. Denver’s wind patterns, especially along the foothills and in open plains areas like Green Valley Ranch, can lift poorly secured caps. A tilted cap channels water into the flue instead of away from it, which is worse than no cap at all.

NFPA 211 Level 2 inspection with camera. Before quoting any cap or crown work, we run a camera down the flue to assess liner condition, check for water damage below the crown, and document the termination from inside and out. This is Haven Standard Clause 4 - a documented photo record on every visit, standard since 2009, not an optional upsell.
- 3
Written price, scope, and warranty delivered on-site. We explain what we found in plain terms - crown integrity rating, cap fit condition, flue liner status - then hand you a written quote with line-item pricing, materials specified by brand and gauge, and our 365-Day Done Right Promise. No work starts until you have this in hand. Haven Standard Clause 1.

Cap or crown work performed with ongoing documentation. For crown repairs, we photograph before, during, and after each stage: routing cracks, applying bonding agent, coating or pouring new concrete. For cap installations, we document proper overhang, secure fastening with stainless hardware, and mesh integrity. You see what was done, not just what was promised.

Final walkthrough with photo archive and warranty registration. We review the completed work with you, provide access to your documented photo record, and register your warranty. The 365-Day Done Right Promise covers labor and materials - if it’s not done right, we make it right. This is stamped on every job, no exceptions.
How Much Does Chimney Cap & Crown Cost in Denver?
A typical chimney cap installation in Denver runs $280-$650 for a single-flue stainless cap with standard mesh and proper overhang. Crown coating on a sound but weathered crown ranges $450-$850 depending on surface area and access complexity. Crown repair with partial concrete rebuild runs $750-$1,400. Full crown replacement, including formwork, reinforcement, and pour, ranges $1,200-$1,850. Custom caps and multi-flue installations start around $650 and scale with metal gauge, finish, and fabrication complexity.
Several factors move these numbers. Access is the big one: steep roofs above 6/12 pitch, multiple stories, or tight alley-side chimney locations in Denver’s older neighborhoods add setup time and safety equipment. Crown size matters too - a 36-by-48-inch crown on a historic home costs more to coat or replace than a 24-by-24-inch slab on a 1980s ranch. Material choice affects longevity and price: galvanized steel caps cost less upfront but show rust in 5-7 years in Denver’s climate; stainless or copper last decades but carry higher initial cost.
To avoid overpaying, get any competitor’s written estimate in writing and bring it to us for a free second opinion. We itemize our quotes so you can compare line by line - cap gauge, fastener type, coating mil thickness, warranty terms. If a quote seems vague, that’s usually intentional. Our price includes the camera inspection, photo documentation, and warranty registration; we don’t split these out as add-ons after you’ve agreed to the work.
Every estimate we provide is free and carries no obligation. Call (720) 674-7312 to schedule.

Frequently Asked Questions - Chimney Cap & Crown in Denver
Chimney cap and crown service covers the installation, repair, and replacement of the metal cap that covers your flue opening and the concrete slab that tops your masonry chimney. The cap keeps water, animals, and debris out of the flue; the crown sheds water away from the flue and protects the chimney structure below. We inspect both components with a camera scan, quote repair or replacement in writing, and document the completed work with photos under Haven Standard Clause 4.
Most cap installations and crown coating jobs take 2-4 hours on-site. Crown repair or full replacement takes 4-6 hours, sometimes spread across two days if concrete cure time is needed between stages. Custom cap fabrication adds 2-3 weeks for measurement, drawing approval, and production. We give you a specific time estimate in your written quote, not a vague range. Call (720) 674-7312 to schedule - estimates are free.
Cap installation runs $280-$650, crown coating $450-$850, crown repair $750-$1,400, and full crown replacement $1,200-$1,850. Custom and multi-flue caps start around $650.
