Why Hearthstone Chimney Co. Is Half Moon Bay’s Preferred Chimney Liner & Rebuild Company

We’ve been driving Highway 92 over the coastal hills to reach Half Moon Bay since 1984. In 42 years, we’ve relined flues in the old Victorians near Kelly Avenue, rebuilt chimney crowns on mid-century cottages in El Granada, and replaced rusted dampers in the newer subdivisions off Purissima Creek Road. Our technicians carry DuraFlex and HeatShield materials on the truck, which means most Half Moon Bay jobs are completed in one visit with no return trip.

Our customers here tend to be longtime homeowners, not flippers. They remember the contractor who never called back. That’s why we answer the phone with a live person, document every inspection with photos the homeowner can see, and back every liner installation and rebuild with our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing.

Half Moon Bay’s geography creates chimney problems you won’t find in San Mateo or Redwood City. The salt-laden fog rolls in off the Pacific, sits on metal components for days, and corrodes chase covers and dampers at a rate inland technicians rarely see. We know what to look for because we’ve seen it hundreds of times. Photos you can see, a plain-English verdict. That’s how we work.

Our Chimney Liner & Rebuild Services in Half Moon Bay

Stainless Steel Liner Installation

Stainless steel liners are the standard for Half Moon Bay’s older masonry chimneys, especially the unlined flues we find in homes built before 1940 near downtown. The marine layer here keeps chimney walls damp year-round, which accelerates deterioration of bare brick and mortar. A properly sized stainless liner from DuraFlex protects the masonry, improves draft in the prevailing northwest winds, and carries a lifetime warranty when we install it. Most stainless liner jobs in Half Moon Bay run $2,800-$4,200 for a single flue.

Flexible Liner for Offset Flues

Many Half Moon Bay chimneys, particularly the tighter flues in beach cottages and hillside homes, have offsets or bends that rigid pipe cannot navigate. We use flexible DuraFlex liners that conform to these irregular shapes without breaking the continuous flue path. This matters in a coastal climate where any gap or seam becomes a collection point for moisture and creosote. Flexible liner installation in Half Moon Bay typically costs $3,200-$4,800 depending on length and access.

Liner Replacement for Failed Clay Tile

Clay tile liners crack from thermal shock and settle over decades. In Half Moon Bay, we also see them deteriorate from the inside out when salt-moisture combinations accelerate spalling. A cracked clay liner is not a repairable item; it needs full replacement. We remove the damaged tiles and install a new stainless or flexible system, often completing the job in one day. Liner replacement in Half Moon Bay generally ranges from $3,500-$5,500.

Partial Chimney Rebuild

When the top courses of brick have spalled, the crown has cracked through, or the chase is rotted out, a partial rebuild restores structural integrity without tearing down the entire chimney. Half Moon Bay’s constant damp means freeze-thaw damage happens even in our mild winters, and salt corrosion attacks metal components that would last decades inland. We rebuild with proper crown slope, adequate overhang, and copper or stainless flashing that can withstand the coastal environment. Partial rebuilds in Half Moon Bay typically run $4,500-$7,500.

Trusted Brands We Service in Half Moon Bay

We install professional-grade materials from DuraFlex, HeatShield, and Famco, with no builder-grade substitutes. Our trucks stock the common liner diameters and fitting configurations for Half Moon Bay’s typical flue sizes, which means we rarely need to order parts and wait. When you’re dealing with a chimney that won’t draw properly on a foggy July evening, that matters. The brands we use are the same ones specified by chimney professionals nationwide because they hold up. Done right, and we stand behind it.

Common Chimney Liner & Rebuild Problems We See in Half Moon Bay Homes

• Rusted-through chase covers on prefab fireplaces. The salt fog along the 94019 coastline destroys uncoated steel chase covers in five to seven years, not the twenty you’d expect inland. Water runs directly onto the firebox and liner, accelerating rust and creating leak paths into wall cavities.
• Cracked clay tile in unlined masonry chimneys near Main Street. These 1920s-era chimneys were often built without liners or with single wythe brick that cannot contain modern appliance temperatures. The persistent damp weakens mortar joints, and thermal cycling finishes the job.
• Corroded damper plates that won’t open or seal. We find this on well-maintained homes throughout Half Moon Bay. The damper looks fine from the fireplace, but the salt air has pitted the metal so severely it either jams shut or leaks conditioned air year-round.
• Downdraft and smoking problems from northwest wind exposure. Homes on the ocean side of Highway 1 or on exposed ridges catch prevailing winds that push smoke back down the flue. The fix is often a combination of proper liner sizing and a wind-resistant cap, not just “airing out the room.”
