Why Hadley Chimney Austin Is San Marcos’s Preferred Chimney Repair Company

Hadley Chimney Austin has been repairing chimneys since 2003, and the San Marcos homes we work on run the full range: 1920s bungalows near the historic districts, 1960s ranches on the east side, and newer builds in the western subdivisions. Every technician who shows up in San Marcos is background-checked, uniformed, and tracked the same way you’d track a rideshare, so you know who’s coming and when. That’s The Relay Visibility Guarantee, and it applies to a $150 cap installation the same way it applies to a $2,500 flue resurfacing.

What separates us in San Marcos specifically is that we don’t treat this as a satellite market. The clay tile liners, the moisture problems, the rental inspection compliance issues: our crews see these every week. When you call for Chimney Repair, you talk to a live person, not a queue. When we arrive, you get a written price before any work starts, and photos after every step. Cory Mitchell leads the team, and the standing rule under his watch is simple: no recommendation without camera evidence you can see for yourself.

Chimney Masonry Repair in San Marcos

Chimney Masonry Repair in San Marcos usually means rebuilding deteriorated mortar joints, replacing spalled bricks, and sometimes rebuilding the top few courses of the chimney crown. The humid subtropical climate here makes masonry work a recurring need: moisture absorbs into brick and mortar, expands during the rare hard freeze, and pops the face off bricks over time. In San Marcos, a mortar repointing job on a typical single-story home runs $800 to $1,600, while a full top section rebuild will land between $1,800 and $3,200.

Repointing and Tuckpointing

When the mortar between bricks crumbles out, water gets behind the brick face and accelerates the damage. We grind out the failed joints to a proper depth and pack in fresh mortar matched to your existing color and profile. On San Marcos homes with heritage brick, we use a lime-forward mix that moves with the house instead of fighting it.

Spalling Brick and Crown Repair

Spalled brick means the face of the brick has popped off, usually from trapped moisture. We cut out the damaged brick, replace it, and then address the source: a cracked crown, missing cap, or failed flashing. A new poured concrete crown with proper overhang costs $600 to $1,100 in the San Marcos market.

Chimney Cap Installation in San Marcos

Chimney Cap Installation in San Marcos is one of the highest-ROI repairs you can make, especially given how much rain this area gets. A stainless steel or copper cap keeps rain from dumping directly onto your flue liner, your damper, and your firebox, and it stops animals from nesting in the stack. Most San Marcos homes need a standard single-flue cap with a spark arrestor, which installed runs $350 to $600. A multi-flue cap or a custom copper cap with a larger footprint will push that to $700 to $1,200.

Olympia Caps and Custom Sizing

We stock Olympia Chimney caps in the most common San Marcos flue sizes, so a standard installation is usually same-visit once we’re on the roof. For odd-sized flues or multi-flue stacks on older east-side homes, we measure and order a custom cap. The wait is a week or two, and it’s worth it: a correctly sized cap is what interrupts the moisture cycle that feeds spalling and liner damage.

Animal and Debris Protection

Raccoons and squirrels find San Marcos chimneys appealing year-round, and a cap with proper screening is the only real deterrent. We’ve pulled everything from bird nests to mummified squirrels out of uncapped flues. The cap also keeps leaves from the pecan and oak trees down near the river from accumulating on your smoke shelf.

Trusted Brands We Service in San Marcos

We install and work with materials from HeatShield, Gelco, and Olympia Chimney, because these are the products that hold up under San Marcos humidity and the thermal shock of occasional hot fires. Using HeatShield for flue resurfacing instead of a full liner tear-out saves San Marcos homeowners thousands, and when we do install a liner, we use DuraFlex flexible stainless systems sized to the existing flue. Parts for these brands are stocked on our trucks for the most common San Marcos repairs, which shortens turnaround when you’re trying to get a rental unit inspection-ready.

Common Chimney Repair Problems We See in San Marcos Homes

• Cracked clay tile flue liners on 1960s and 1970s east-side homes. The original terracotta liners can’t handle the thermal stress of a hot fire after months of no use, and the cracks open a direct path for heat to reach framing. A Chim-Scan camera inspection is the only way to see this before it becomes a fire.
• Moisture-driven spalling on older brick chimneys near the historic districts. Humid air, heavy rain, and old mortar combine to pop brick faces and erode crowns, and once water gets inside the masonry, every freeze cycle makes it worse.
• Hardened second-degree creosote in decorative-only fireplaces. San Marcos has a lot of fireplaces that get lit twice a year, and those sporadic burns produce creosote that hardens into a glaze. This has to be mechanically removed before any liner repair can be safely evaluated.
• Scored flue walls in newer prefabricated chimneys. Some west-side subdivision homes get swept with wire brushes meant for masonry chimneys, which scores the metal flue and voids the manufacturer’s warranty. We use the correct brushes and document flue condition with photos before and after every sweep.
