Littleton’s older homes often hide decades of creosote, soot, and debris in brick chimneys—especially in masonry that’s shifted with age. Our sweeping process removes every trace of flammable buildup while our high-definition camera identifies cracks, missing mortar, or liner damage that could let heat escape into your walls. We focus on brick chimneys, where mortar joints degrade faster than modern flues, and we’ll show you the footage so you see exactly what we’re fixing. No shortcuts—just a chimney restored to code and ready for safe use.
Request this service →Older brick chimneys weren’t built for modern appliances, and unlined flues can transfer dangerous heat to combustible walls or allow carbon monoxide to seep into your home. We install UL-listed stainless steel liners sized for your fireplace or stove, sealing gaps in cracked masonry to restore draft efficiency. In Littleton’s older neighborhoods, we often find liners that were patched with duct tape or improperly sized—we replace those with durable, insulated liners that meet current safety standards and come with a 10-year warranty.
Request this service →Littleton’s freeze-thaw cycles wreak havoc on older brick chimneys, causing mortar to crumble and bricks to shift. We repoint mortar joints with Type N or Type S mortar, matching historic blends where needed, and seal the chimney crown to prevent water intrusion. Our waterproofing treatment bonds to brick without trapping moisture inside—unlike cheap sealants that can trap water and accelerate decay. We’ll restore your chimney’s structural integrity so it weathers Littleton’s winters without collapsing into your living room.
Request this service →A missing or damaged chimney cap is an open invitation for squirrels, raccoons, and Littleton’s heavy snow to clog your flue. We install custom-fit caps with mesh screens to block pests and a 1/4-inch mesh to prevent embers from escaping onto your roof. Our caps are designed to withstand Colorado’s wind and snow loads, and we’ll ensure they’re secured properly to your chimney’s crown—no wobbling, no leaks. A $200 fix now saves you thousands in water damage or animal removal later.
Request this service →If your Littleton home’s chimney has been used for wood stoves, pellet inserts, or even forced-air heating in the past, the flue may be cracked, corroded, or lined with incompatible materials. We remove old, unsafe liners and install new ones—whether rigid stainless steel for wood-burning fireplaces or flexible liners for retrofit inserts. We’ll match the liner to your appliance’s BTU output to prevent overheating and ensure your chimney meets Littleton’s building codes. No guesswork, just a safe, efficient system.
Request this service →Littleton’s dramatic temperature swings crack chimney crowns, allowing water to seep into the masonry and freeze, expanding cracks further. We rebuild crowns with reinforced concrete or install pre-cast crowns that overhang the chimney’s edge, sloping away from the flue to shed water. Our repairs include sealing joints with elastomeric caulk to prevent future leaks. A solid crown isn’t just cosmetic—it’s the first line of defense against Littleton’s weather and your chimney’s longevity.
