Sunnyvale homes often feature striking stone and brick chimneys built with craftsmanship and quality materials. However, even the finest masonry requires maintenance. North Texas freeze-thaw cycles and severe summer thunderstorms take a toll on mortar crowns, metal chase flashing, and interior chimney liners.
When unseasoned oak or pecan wood is burned during sudden winter cold snaps, flammable creosote accumulates quickly on cold flue walls. Hearthguard delivers thorough cleaning and detailed inspections designed to keep your Sunnyvale fireplace drafting smoothly and burning safely.

Frequently Asked Questions in Sunnyvale, TX
How do I know if my damper is stuck?
If you feel resistance when turning the lever, or smoke billows into your living room upon lighting kindling, your damper may be rusted, off its tracks, or warped from heat. We lubricate and realign dampers during our visits.
Can you fix cracked firebox mortar?
Yes. We repoint damaged refractory mortar joints using heat-resistant refractory cement to prevent heat from transferring to adjacent framing.
