Why Hearthstone Chimney Co. Is Ontario’s Preferred Chimney Liner & Rebuild Company
Ontario’s chimney problems are not generic. The mid-century tract homes clustered near downtown and the original Ontario High School corridor were built with clay-tile flue liners that have now endured sixty-plus years of thermal cycling, low-humidity mortar shrinkage, and the seismic stress that runs through this part of the Inland Empire. We’ve replaced liners on Bon View Avenue, rebuilt crowns in the 91764 grid, and pulled bird nests from flues in the older courts off Mission Boulevard. Our technicians carry the camera equipment to document what we find, show you the photos, and explain the verdict in plain English.
Our reputation here is built on showing up when we say we will and standing behind the result. The 90-Day Done Right Promise is in writing, with no arguing and no paperwork chase. If it’s not right, we come back. That’s been our standard since 1984.
Calls are answered by a live person, not a queue, not an app. Background-checked, uniformed technicians arrive with professional-grade materials from DuraFlex, HeatShield, and Famco already on the truck. Most jobs finish in one visit. The estimate you approve is the number on the invoice.
Our Chimney Liner & Rebuild Services in Ontario
Stainless Steel Liner Installation
A stainless steel liner is the permanent fix for a cracked clay flue in an Ontario masonry chimney. We size and install DuraFlex and Olympia Chimney systems rated for wood, gas, and pellet appliances, with proper top-sealing collars and insulation blankets that meet California building code for clearance to combustibles. In the 91762 ZIP code, where original terra-cotta flue tiles are often fractured by decades of seismic movement, a stainless liner restores safe draft and protects the masonry surround. Most installations run four to six hours and are done in one day.

Flexible Liner for Offset Chimneys
Not every Ontario flue runs straight. The offset chimneys common in 1950s and 1960s ranch homes near the historic downtown grid require a flexible liner that can navigate bends without losing draft performance. We measure the offset with a camera first, then specify the correct diameter and length of flexible stainless from DuraFlex or Copperfield. A poor flex install creates new dead spots for creosote, so we verify the full run with a post-installation pull test and camera pass. You’ll see the before and after photos.

Liner Replacement for Zero-Clearance Fireboxes
The production homes built across Ontario Ranch and the 91761 ZIP code in the 2000s and 2010s use factory-built zero-clearance fireboxes with proprietary metal liners, not masonry. These liners corrode, warp, or separate at the seams after fifteen to twenty years of concentrated use. Because South Coast AQMD no-burn days compress Ontario’s burning season into a handful of nights each winter, these liners often fail faster than the manufacturer anticipated. We source replacement parts from Famco and Gelco, inspect the surrounding chase and termination cap, and restore the system to factory specifications.

Partial Chimney Rebuild
When the liner damage has progressed to spalled brick, deteriorated mortar joints, or a compromised smoke chamber, a liner alone won’t solve it. Our partial rebuilds address the specific failed section, whether that’s the top four feet of flue wall, the smoke chamber parging, or the firebox floor. We match existing brick and mortar color where possible, and we never recommend more demolition than the condition requires. In Ontario’s semi-arid climate, where low humidity accelerates mortar joint deterioration, catching this early prevents the full rebuild nobody wants.

Common Chimney Liner & Rebuild Problems We See in Ontario Homes
- Cracked terra-cotta flue tiles from seismic stress. The 1992 Big Bear and Landers earthquakes fractured liners across the older Ontario core, and subsequent tremors have worsened hidden damage. Our Level-2 camera inspections catch what a flashlight from below cannot.
- Accelerated creosote buildup from compressed burning seasons. South Coast AQMD no-burn curtailment days force Ontario residents to concentrate fireplace use into narrow windows, creating dense, glazed creosote deposits that corrode metal liners and degrade clay.
- Santa Ana wind debris infiltration through the Cajon Pass. Strong downdrafts push leaves, nesting material, and dust deep into uncapped or poorly capped flues, blocking liners and introducing moisture that spalls brick from the inside out.
- Failed zero-clearance liners in Ontario Ranch production homes. The metal flue systems in 2000s-era builds were engineered for moderate, distributed use, not the intense seasonal loading that AQMD restrictions create. We see separation, corrosion, and draft reversal in these units well before the twenty-year mark.
