Why Northglenn Homeowners Choose Hearthstone Chimney Co.

We’ve been sweeping and inspecting chimneys in Northglenn’s original subdivisions long enough to recognize the house before we pull in the driveway. The Perl-Mack ranch on East 112th Avenue with the painted brick and the oversize flue. The split-level off Huron Street where the homeowner installed a gas log set in 1994 and nobody has looked up the chimney since. These patterns repeat because Northglenn was built in a single, concentrated burst, and so do the failures.

Our technicians are background-checked and uniformed. They carry Hearthstone‘s 90-Day Done Right Promise, backed in writing with no arguing. Most jobs finish in one visit. You’ll get photos from the camera inspection you can see for yourself, and a plain-English verdict on what needs doing now, what can wait, and what to watch. No surprises on the bill. The number on the estimate is the number on the invoice.

We answer the phone with a live person 24 hours a day, 7 days a week. Not a callback queue. Not an app. A human being who can schedule you, answer a question, or dispatch a technician if smoke is backing up into your living room on a Sunday evening in February.

Why Northglenn’s Climate & Housing Affect Chimney Cleaning

Northglenn sits at roughly 5,400 feet on Colorado’s Front Range, and that elevation matters more than most homeowners realize. From October through April, the temperature swings between single-digit nights and fifty-degree afternoons create sharp freeze-thaw cycling in masonry chimneys. Water seeps into hairline cracks at noon, freezes by midnight, and widens the gap by morning. We’ve repointed more crowns in Northglenn than in lower-elevation cities like Thornton or Westminster simply because the cycling is more aggressive here.

The housing stock compounds the issue. Northglenn was built almost entirely between 1959 and 1972 as one of Colorado’s first master-planned suburban communities, meaning the city contains a dense, uniform block of same-vintage masonry chimneys now 50-65 years old. This is precisely the age when original clay tile flue liners crack, mortar crowns spall, and 1960s-era cast-iron dampers corrode past function. Unlike neighboring Thornton or Denver proper, which have mixed housing vintages, Northglenn’s single-era construction window means systematic chimney deterioration is a neighborhood-wide pattern rather than a house-by-house surprise.

Then there are the Chinooks. Northglenn lies in the corridor for powerful downslope wind events that create negative pressure at chimney tops, back-draft flues, and force debris into uncapped stacks. Every late winter we field calls from homeowners on East 112th Avenue and along Malley Drive who’ve had their fireplace smoke into the room during a 60-mph wind event. A properly sized cap and a functional damper assembly prevent most of these, but both are often original equipment from 1965.

The most serious pattern we find is specific to Northglenn’s gas retrofit history. On block after block in the original Perl-Mack neighborhoods, technicians find the same failure: a 1963-era oversized masonry flue fitted with a 1990s gas insert and no liner, where years of condensing flue gases have eaten through the original tile and the homeowner has no idea because the gas flame still lights. Until a CO test or a visual scope reveals a cracked, open flue exhausting into the chase cavity. This is why we camera-inspect every chimney we clean, regardless of fuel type or apparent condition.
