Aurora’s freeze-thaw cycles take a brutal toll on brickwork, especially in homes built before 1950. Our masonry inspections go beyond surface checks—we use moisture meters, borescopes, and 3D imaging to spot hidden deterioration in your chimney’s brick, mortar joints, and crown. We document every crack, loose brick, or eroded joint with photos and a detailed report, so you know exactly what needs fixing. Repairs include repointing with high-temperature mortar, crown sealing to prevent water intrusion, and rebuilding damaged sections to match original aesthetics. No patchwork solutions—just durable, code-compliant fixes that preserve your home’s character.
Request this service →Many Aurora homes built before 1970 lack proper chimney liners—or have cracked clay tiles that fail under heat. We install seamless stainless steel liners (flexible or rigid) sized to your fireplace’s BTU output, ensuring optimal draft and safety. For historic masonry, we offer cast-in-place liners that reinforce the flue without altering exterior brickwork. All liners come with a 5-year warranty and meet Aurora’s strict building codes. We also replace deteriorated clay liners with durable, insulated options that improve efficiency and reduce creosote buildup.
Request this service →Creosote in Aurora’s drafty, older chimneys builds up faster than in modern homes—thick layers of glaze or flaky deposits that ignite at just 451°F. Our process uses rotary brushes, HEPA vacuums, and chemical treatments to remove 100% of creosote, even in hard-to-reach offsets. We don’t just scrape the flue; we inspect for hidden cracks where creosote can hide and treat them to prevent future buildup. Includes a free carbon monoxide test to verify your chimney’s draft is safe post-cleaning.
Request this service →Aurora’s hailstorms and sudden temperature swings crack chimney crowns, letting water seep into brick and mortar. We rebuild eroded crowns with reinforced concrete, install custom copper or stainless steel caps to block debris and animals, and apply a breathable waterproof sealant to the exterior brick. Our crowns are sloped to shed water and include a drip edge to protect the masonry below. Prevents costly freeze-thaw damage and extends your chimney’s lifespan by decades.
Request this service →Older fireplaces in Aurora often have flues that are too large, too small, or lined with crumbling clay tiles. We assess your fireplace’s burn rate and install a liner that matches its original design intent—whether that’s a 6-inch rigid liner for a Rumford-style hearth or a custom-sized flexible liner for a decorative brick surround. Includes smoke chamber smoothing to improve draft and prevent downdrafts. All work is documented for insurance and resale purposes.
Request this service →Aurora’s severe weather can dislodge bricks, crack liners, or even spark chimney fires that weaken masonry. We respond within 24 hours to stabilize damaged chimneys, replace shattered tiles, and install temporary caps to prevent water intrusion. For fire-damaged flues, we perform a full thermal scan to identify compromised sections and rebuild them with fire-rated materials. Includes a free safety inspection and estimate for permanent repairs.
