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. That’s precisely the age when original clay tile flue liners crack, mortar crowns spall, and 1960s-era cast-iron dampers corrode past function - which is why Chimney Liner & Rebuild in Northglenn is among our most common services. 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 walked the original Perl-Mack neighborhoods - from the streets near E.B. Rains Jr. Memorial Park to the blocks off 120th Avenue - and found the same failure again and again: 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 scare tactic. That’s what we document with photos you can see and explain in plain English.
Our Chimney Repair team knows the 80241 zip code well. We’ve responded to calls along Washington Street, worked on ranch houses near Fox Run Golf Course, and traced water stains in split-levels off Huron Street. At 5,400 feet on the Front Range, Northglenn’s sharp freeze-thaw cycling from October through April accelerates mortar joint erosion and crown cracking faster than lower-elevation cities. Add the Chinook downslope wind events that create negative pressure at chimney tops, back-draft flues, and force debris into uncapped stacks, and you’ve got a climate that punishes chimneys built to mid-century standards. We don’t guess at what’s wrong. Our Level-2 camera inspections end with photos and a verdict you can understand.

Our Chimney Repair Services in Northglenn
Mortar Repointing
The mortar joints in a 1965 Northglenn chimney have endured five decades of Front Range temperature swings. When we grind out failed mortar and repoint with color-matched, professional-grade mix, we’re restoring structural integrity, not just cosmetics. In original Perl-Mack neighborhoods, we often find mortar erosion depth of an inch or more - past the point where simple surface patching holds. A typical mortar repointing job in Northglenn runs $380-$720 for a standard ranch chimney.

Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - accelerates where water has saturated the masonry and freeze-thaw cycles pry the surface apart. Northglenn’s elevation and exposure make this worse than in lower-lying Commerce City or Thornton. We remove damaged brick, match replacement units for color and texture, and address the water source so the repair lasts. Spalling brick repair in Northglenn typically costs $450-$950 depending on how many courses are affected and whether the crown is also compromised.

Chimney Waterproofing
Colorado’s semi-arid reputation tricks some homeowners into thinking chimneys don’t need waterproofing. The reality in Northglenn: Chinook-driven rain and snow intrusion, combined with freeze-thaw, destroy unprotected masonry. We apply vapor-permeable sealers from professional-grade lines that let the chimney breathe while blocking liquid water. A full chimney waterproofing treatment in Northglenn runs $280-$480 and carries our 90-Day Done Right Promise.

Flashing Repair
The junction where chimney meets roof is the most leak-prone point in the system. On Northglenn’s low-slope ranch roofs, improper flashing installation from the original build or subsequent re-roofing jobs creates chronic water entry. We fabricate and install stepped counter-flashing and base flashing to shed water correctly, not just caulk over the problem. Flashing repair in Northglenn typically ranges from $320 for spot repair to $680 for full replacement on a standard chimney.

Trusted Brands We Service in Northglenn
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For Northglenn repairs, we stock and install HeatShield cerfractory flue resurfacing systems for cracked clay liners, Gelco chimney caps and accessories sized for standard Northglenn flue dimensions, and Famco chimney components for damper and repair hardware. Olympia Chimney stainless steel liners handle the gas insert conversions we regularly perform in 1960s Perl-Mack fireplaces. These aren’t catalog items we order after the fact. We keep common sizes on hand so your repair moves quickly, not through a two-week special-order delay.
Common Chimney Repair Problems We See in Northglenn Homes
- Cracked clay flue liners from gas insert condensation. The 1980s-90s gas log boom left countless Northglenn chimneys with undersized appliances venting into oversized flues. Acidic condensate has silently degraded the original tile for decades. We find this on block after block - the homeowner sees a working flame, but a Level-2 scope reveals a cracked liner exhausting into the chase cavity.
- Spalled mortar crowns from freeze-thaw cycling. Northglenn’s 5,400-foot elevation means more freeze-thaw events per winter than lower Front Range cities. A crown with even hairline cracks absorbs water, freezes, and fractures further until the crown is no longer shedding water but funneling it into the chimney structure.
- Corroded cast-iron dampers from 1960s original builds. These dampers were never designed for sixty years of service. We replace them with functional throat dampers or top-sealing dampers that seal far better and save on heating bills.
- Wind-driven debris and back-drafting from Chinook events. Northglenn’s position in the downslope wind corridor means uncapped chimneys collect leaves, twigs, and nesting material while experiencing pressure differentials that reverse flue flow. A proper cap installation prevents both problems.
