Alex & Sons Chimney Repair in Santee has delivered chimney sweeping, inspection, and masonry restoration from Prospect Avenue since 2007. Certified technicians use video-scanning cameras to inspect flue interiors for creosote buildup and liner damage, identifying electrical-ignition faults in gas fireplace systems that require the code-compliant wiring work of Keil Electric on Magnolia Avenue. The service menu covers chimney relining with stainless-steel and aluminum liner systems, crown repair, cap replacement, and full masonry tuckpointing for brick-and-mortar chimneys. Chimney-to-roof flashing repair — replacing the sheet-metal seal where the chimney stack penetrates the roofline — addresses the same weather-barrier integrity that Top Flight Roofing maintains from Cuyamaca Street. Waterproofing treatments apply siloxane-based sealant to exterior masonry, and fireplace installations include direct-vent, B-vent, and wood-burning insert options sized to California Mechanical Code Chapter 9 clearance-to-combustibles requirements.
