Why Hearthstone Chimney Co. Is Northglenn’s Preferred Chimney Cap & Crown Company

Northglenn homeowners don’t call us once. They call us when they bought the house in 1987, again when their son notices the crown crumbling in 2019, and a third time when they’re ready to pass the place to the next family. That pattern - repeat customers across two generations on the same block - is how we’ve built our reputation here. We’ve earned strong local reviews from Northglenn customers who mention specifically that we showed them camera photos of their flue, explained what was actually wrong, and charged exactly what we quoted.

Our response time to Northglenn runs same-day or next-day for standard calls, because we’re already working in Thornton and Westminster most weeks. We don’t subcontract to crews who need GPS to find 80241. We know that a cap call on a Fox Run cul-de-sac and a crown repair off Huron Street face different wind exposures, different roof pitches, and often the same vintage of original clay flue tile. That local fluency saves time and prevents the second visit that costs you another day off work.

Russell Haines has led Hearthstone Chimney Co. since its founding, and the steady, plainspoken approach he established still governs how we treat Northglenn homes: photos you can see, a plain-English verdict, and a written 90-Day Done Right Promise with no arguing if something needs adjustment.

Our Chimney Cap & Crown Services in Northglenn

Cap Installation

New cap installation in Northglenn runs $280-$520 for a standard single-flue galvanized or stainless unit, with multi-flue and custom caps ranging higher. We size caps to your flue and your roofline, not to whatever fits in the truck. In Northglenn’s Perl-Mack neighborhoods, we regularly find original chimneys that never had a cap installed - standard practice in 1964, but a real liability after six decades of Front Range freeze-thaw and wind-driven debris. A proper cap stops water at the top, blocks the squirrels that nest in uncapped flues every spring, and reduces the downdraft pressure that Chinook winds create on exposed chimney openings. We install Famco and Copperfield caps with stainless hardware that outlasts the big-box alternatives.

Cap Replacement

Cap replacement in Northglenn typically costs $240-$480, assuming the flue tile and crown beneath are sound. Often they’re not. We remove the old cap, inspect what it was hiding, and show you photos before we quote anything further. Northglenn’s 1960s chimneys frequently have caps that were added decades after construction, poorly fitted, or secured with hardware that rusted through after twenty Colorado winters. We replace with correctly sized units and proper mounting methods - no leaning, no gaps, no galvanized straps that’ll fail again in five years.

Crown Repair

Crown repair in Northglenn averages $380-$650 for a standard pour-and-seal, with full crown rebuilds running $720-$1,100 for larger or severely deteriorated units. The crown is the concrete or mortar slab that seals the chimney top between the flue tiles and the brick edge. In Northglenn’s climate, crowns take a beating: sharp freeze-thaw cycling from October through April opens hairline cracks that become water channels, and by spring the steel reinforcement inside is rusting and spalling the surface. We pour new crowns with proper slope and overhang, or apply professional-grade crown coating where the structure is sound but the surface is porous. Our crown work carries the 90-Day Done Right Promise - in writing, no arguing.

Crown Coating

Crown coating in Northglenn costs $280-$440 and extends the life of a structurally sound crown by sealing the surface against water intrusion. Not every cracked crown needs rebuilding. Where the crown still has integrity but the surface has weathered porous, we clean and apply a flexible, breathable sealant formulated for masonry chimney tops. This is often the right call for Northglenn homeowners whose crowns are showing early wear but haven’t yet failed structurally - a preventive fix that avoids the larger expense of a full rebuild two winters later. We’ll tell you honestly which category you’re in, because a coating on a crumbling crown is money thrown away.

Trusted Brands We Service in Northglenn

We work exclusively with professional-grade materials - DuraFlex, HeatShield, Famco, and Copperfield - because a cap or crown that fails in five years is no bargain at any price. For Northglenn customers, this means we stock common cap sizes and crown coating materials locally, so we’re not ordering parts that delay your job. When we quote a Famco stainless cap or a HeatShield crown repair, we’re specifying a product with a documented performance history in Colorado’s high-elevation, high-UV, freeze-thaw environment. No builder-grade substitutes, no guessing whether it’ll hold up on your roof at 5,400 feet. The brands we use are the same ones specified by chimney professionals nationwide, and we install them to manufacturer standards - done right, and we stand behind it.

Common Chimney Cap & Crown Problems We See in Northglenn Homes

• Spalling mortar crowns on 1960s Perl-Mack chimneys. The original crowns in Northglenn’s first master-planned neighborhoods were often poured with too little slope and no overhang, trapping water that freezes, expands, and flakes off the surface in sheets. We see this on block after block between 104th and 120th Avenues.
• Missing or ill-fitting caps allowing Chinook debris entry. Northglenn’s position in the Front Range corridor means powerful downslope wind events that force leaves, twigs, and sometimes nesting material straight down an uncapped flue. Every late winter, we clear blocked flues that started with a missing cap and ended with a smoking fireplace or a CO concern.
• Gas insert corrosion in unlined oversized flues. The distinctive Northglenn pattern: a 1963-era masonry fireplace fitted with a 1990s gas insert, venting into an flue never sized for condensing appliances. Years of acidic condensation degrade the clay tile and corrode the damper, while the homeowner assumes the appliance is “working fine” because the flame still lights. A proper cap and crown won’t fix the liner, but they slow the water intrusion that accelerates the damage - and our camera inspection catches what the flame hides.
• Crown cracks from sharp freeze-thaw cycling. At 5,400 feet, Northglenn experiences more extreme temperature swings than lower Front Range cities. A crown that might last twenty years in Pueblo can fail in twelve here. We factor that elevation stress into our material selection and our repair recommendations.
