Northridge sits in the heart of the San Fernando Valley, where the 1950s-to-1970s ranch homes along Tampa Avenue and Reseda Boulevard hold fireplaces that are now fifty to seventy years old. Many were patched after the 1994 earthquake by contractors who never pulled permits and never installed proper liners. That history lives inside your chimney walls, and it is our job to find it before you light a fire.
We serve every Northridge ZIP code - 91324, 91325, 91327, and 91330 - from Porter Ranch Estates down to the homes south of Nordhoff Street. Our technicians carry DuraFlex and HeatShield materials on every truck, so we do not waste a trip ordering parts. When we say we will be there, we are there.

Our Chimney Liner & Rebuild Services in Northridge
Stainless Steel Liner Installation
A stainless steel liner is the correct fix for most Northridge chimneys with cracked terra-cotta flue tiles. We install DuraFlex stainless steel liners that carry a lifetime warranty and meet California building code for wood-burning and gas appliances. In Northridge’s 1960s ranches, we frequently find the original clay tile has shifted at the mortar joints since 1994, creating gaps that let combustion gases leak into wall cavities. A stainless steel liner seals the entire flue path and restores proper draft. Most installations in Northridge run $2,400-$3,800 for a standard one-flue chimney.

Flexible Liner Solutions
Some Northridge chimneys have offset flues or tight smoke chambers that a rigid liner cannot navigate. Our flexible liners, also from DuraFlex, bend around offsets while maintaining the same corrosion resistance. This matters in post-earthquake rebuilds where the original flue path was altered without documentation. We camera-inspect first to map the interior geometry, then select the right diameter and flexibility grade. A flexible liner installation in Northridge typically costs $2,200-$3,600.

Liner Replacement
If your existing metal liner has corroded through or was undersized for your fireplace insert, we remove and replace it with a properly sized new system. In Northridge, we see this problem in homes where a previous owner installed a wood stove into a fireplace opening without upgrading the liner diameter. The result is creosote buildup and poor draft. We measure the appliance output, calculate the required flue size, and install a replacement that matches. Liner replacement in Northridge generally runs $1,800-$3,200.

Partial Chimney Rebuild
When the upper courses of masonry or the smoke chamber are damaged but the firebox and foundation remain sound, a partial rebuild saves the structure without the cost of starting over. This is common in Northridge for chimneys that took structural damage in 1994 but were never properly repaired. We rebuild the affected courses with matching brick or block, install a proper liner, and pour a new concrete crown. Partial rebuilds in Northridge typically range from $3,500-$5,500.

Full Chimney Rebuild
Some Northridge chimneys are beyond saving. When the firebox is cracked, the foundation has shifted, or multiple flues are compromised, we dismantle and rebuild from the ground up. This is the only safe option for certain post-1994 patch jobs where unlicensed contractors stacked incompatible materials. Our full rebuilds use professional-grade materials from Copperfield and Olympia Chimney, with proper clearance to combustibles and a new stainless steel liner as standard. Full rebuilds in Northridge run $5,000-$8,500 depending on height and access.

Common Chimney Liner & Rebuild Problems We See in Northridge Homes
- Earthquake-patch chimneys with hidden tile displacement. After 1994, unlicensed contractors stuccoed over cracked flues to pass visual inspections. Thirty years later, the mortar has deteriorated and the tiles have shifted further, creating voids in the smoke chamber that vent carbon monoxide into living spaces. Only a Level-2 camera inspection reveals this.
- Unlined or improperly retrofitted post-earthquake repairs blocking new liner installation. Some 1990s rebuilds filled the flue with rubble or installed non-compliant single-wall pipe that now obstructs a proper stainless steel liner. We have to remove the obstruction or partially dismantle the chimney to create a clear path.
- Shifting mortar joints from seismic damage causing liner snags or kinks. Even small offsets in the flue path can kink a flexible liner during installation, creating a creosote trap or gas leak point. We find these with pre-installation camera runs and correct the masonry before the liner goes in.
- Debris accumulation from damaged crowns in intermittently used chimneys. Northridge fireplaces see only a handful of uses per year due to mild winters. Birds, squirrels, and leaves enter through cracked crowns, and by the time the homeowner lights a fire, the flue is partially blocked. Santa Ana winds accelerate crown deterioration between uses.

FAQs - Chimney Liner & Rebuild in Northridge
Yes, you likely still need an inspection, and many Northridge chimneys that looked fine after 1994 have hidden flue tile displacement. The 1994 Northridge earthquake shifted terra-cotta tiles inside masonry chimneys even when the exterior stucco showed no cracks, and those tiles have continued to deteriorate for thirty years. We find displaced tiles and voided mortar joints in apparently intact chimneys during routine Level-2 camera inspections. Call (844) 418-0954 for a free inspection - estimates are free.
In most cases, yes. We install stainless steel and flexible liners through the existing flue opening without dismantling exterior masonry, provided the flue path is clear and the smoke chamber is sound. For 1960s Northridge ranches with original construction, we camera-inspect first to confirm the flue is unobstructed and properly sized. If a previous owner or post-1994 contractor altered the flue, we may need minor masonry work to create a clear path. Call (844) 418-0954 and we will tell you exactly what your chimney needs after inspection.
An earthquake-patch chimney has a visually intact exterior that conceals internally displaced flue tiles, voids in the smoke chamber, or non-compliant venting materials installed after 1994. The danger is that combustion gases including carbon monoxide leak through gaps in the flue into wall cavities and living spaces, and creosote can ignite in hidden voids. In the South of Nordhoff neighborhood, we inspected a 1964 ranch with a post-1994 stucco patch. The homeowner smelled smoke indoors after one use. Our camera found a terra-cotta tile that shifted 3 inches during the quake and was mortared over. We installed a DuraFlex stainless steel liner and rebuilt the smoke chamber. Now the fireplace is code-compliant and safe. Call (844) 418-0954 if your home was repaired after 1994 - we will check what was actually done.
Cracked crowns must be repaired before or during liner installation because they allow water, debris, and animals to enter the flue and damage the new liner. Northridge’s Santa Ana wind events accelerate crown deterioration by driving dust and debris into hairline cracks, which then expand with winter moisture. We repair or pour new crowns as part of our liner installations when needed, using professional-grade materials that withstand the valley’s dry heat and wind exposure. Call (844) 418-0954 for an inspection - we will assess the crown and include any needed repair in your upfront estimate.
The only way to know is a Level-2 camera inspection that documents the interior condition with photos you can see. Proper retrofitting after 1994 required a permit, code-compliant liner installation, and inspection by the city. Many Northridge retrofits skipped one or all of these steps. We have found chimneys where “retrofit” meant stucco over a cracked flue, or where a non-listed metal pipe was shoved into the flue without proper clearance. Our inspection gives you a plain-English verdict and photos. If the work was not done right, we explain what it takes to fix it and quote upfront. Call (844) 418-0954 - the estimate is free, and you will know exactly what you have.
