Fast, Reliable Chimney Liner & Rebuild Across Northglenn
Chimney liner replacement and rebuild work in Northglenn typically runs $2,200-$6,800 depending on whether we’re dropping a stainless steel liner into an existing flue or rebuilding from the roofline up. Most of our Chimney Liner & Rebuild jobs in the 80241 area are completed in a single day, and we carry the inventory to do it.
We’ve been working on Northglenn chimneys since 1984. Russell Haines and our team know the Perl-Mack ranch homes along 112th Avenue, the split-levels near Huron Street, and the brick fireplaces that were standard issue in 1963. When a Northglenn homeowner calls (844) 803-1545, a live person answers - every hour, every day - and we can usually be there within 24 hours. That matters when you’re smelling smoke in the living room or your CO detector won’t stop chirping.
Why Hearthstone Chimney Co. Is Northglenn’s Preferred Chimney Liner & Rebuild Company
Northglenn was built almost entirely between 1959 and 1972 as one of Colorado’s first master-planned suburban communities. That means the city contains a dense, uniform block of same-vintage masonry chimneys now 50-65 years old - 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. We’ve replaced liners on the same block three houses in a row. The homeowners talk to each other, and they call us because we’ve already solved the exact problem they’re facing.
Our technicians are background-checked, uniformed, and trained to complete most liner and rebuild jobs in a single visit. We document every inspection with photos you can see and a plain-English verdict - no jargon, no scare tactics. The 90-Day Done Right Promise backs every job in writing: if it’s not right, we come back, no paperwork, no arguing. That’s the K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it - and it’s how we’ve operated for over 42 years.
Calls from Northglenn get a live person, not a voicemail tree. We’ve answered the phone that way since 1984, and we don’t plan to stop.
Our Chimney Liner & Rebuild Services in Northglenn
Stainless Steel Liner Installation
A stainless steel liner is the standard permanent fix for a deteriorated clay flue in Northglenn’s 1960s masonry fireplaces. We use DuraFlex and Olympia Chimney products, sized precisely to your appliance - whether that’s a wood-burning fireplace, a pellet stove, or a gas insert you added in 1992. Most stainless installations in Northglenn run $2,200-$3,800 for a straight flue, with permits pulled through the city and work completed in one day. The liner carries a lifetime warranty when we install it, and it’s the only solution we recommend for homes along Washington Street and Fox Run where the original clay is past saving.
Flexible Liner Installation
Northglenn’s ranch homes often have offset flues - a jog in the chimney chase that was cheaper to build but impossible to line with rigid pipe. A flexible liner navigates those offsets without breaking the flue wall, and we can pull it through from the roof in most cases without opening drywall. Flexible installations in Northglenn typically cost $2,600-$4,200 depending on length and diameter. We stock the common sizes for the area, so you’re not waiting two weeks for parts while the heating season passes.
Liner Replacement
Sometimes a previous installer used the wrong material, or a liner installed in the 1990s has corroded through at the joints. We remove the failed liner - carefully, without damaging the surrounding masonry - and install a new system sized to current NFPA 211 standards. Replacement jobs in Northglenn run $2,800-$4,500. We see this scenario constantly in the original Perl-Mack neighborhoods: 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. That’s not a hypothetical. We found three of them last winter within a mile of each other near Malley Drive.
Partial Chimney Rebuild
When the crown is gone, the top courses are spalling, and the flue liner is sitting in rubble, a partial rebuild from the roofline up is often more economical than piecing it together. We rebuild with matching brick where possible, install our Chimney Cap & Crown in Northglenn with proper overhang and drip edge, and install a new liner system as one integrated job. Partial rebuilds in Northglenn typically range from $4,200-$6,800. The freeze-thaw cycling at 5,400 feet on the Front Range accelerates mortar joint erosion faster than lower-elevation cities, so we use a modified mortar mix rated for Colorado’s temperature swings. A rebuild done with standard Type N mortar won’t last here - we’ve seen it, and we don’t do it.

Trusted Brands We Service in Northglenn
We work exclusively with professional-grade materials: DuraFlex and Olympia Chimney for stainless and flexible liners, HeatShield for cerfractory resurfacing when the flue is sound but the surface is degraded, and Copperfield and Famco for caps, dampers, and fittings. We keep common sizes in stock for Northglenn’s typical flue dimensions - 8×8, 8×12, and 10×10 for the mid-century ranch stock - so most jobs don’t wait on shipping. If you’ve got a specialty appliance or an unusual chase configuration, we’ll measure twice and order once, but the standard Northglenn fireplace doesn’t need special handling. It needs the right material, installed correctly, backed by a promise in writing.
Common Chimney Liner & Rebuild Problems We See in Northglenn Homes
- Undersized gas inserts venting into oversized flues. In the 1980s and 90s, Northglenn homeowners added gas logs to original wood fireplaces without installing a properly sized liner. The result: an appliance producing 50,000 BTU venting into a flue designed for 150,000. Acidic condensation pools on the clay tile, silently degrading it for decades. We find this on block after block in the original Perl-Mack neighborhoods.
- Cracked crowns letting water into the chase. Northglenn’s sharp freeze-thaw cycling from October through April turns a hairline crown crack into spalled brick in two seasons. By year three, water is rusting the damper and saturating the firebox wall. We rebuild crowns with proper slope and overhang, not a skim coat that’ll crack again next spring.
- Chinook wind damage to uncapped flues. Those powerful downslope wind events that roll through the Front Range create negative pressure at chimney tops, back-drafting flues and forcing debris into uncapped stacks. Every late winter we get calls from Northglenn homeowners who lit a fire and filled the house with smoke because a bird’s nest or wind-driven snow blocked the flue. A proper cap with wind-resistant screening prevents it.
- Original clay tile liners past their service life. The clay flue liners in Northglenn’s 1960s chimneys were rated for roughly 50 years under ideal conditions. They’re now 50-65 years old, and ideal conditions never existed. Vertical cracking, shaling, and mortar washout between tile joints are standard findings on our Level-2 camera inspections. Replacement isn’t optional at this point - it’s a safety issue.
