Chimney repair in Alpharetta, GA
A chimney that looks fine from the ground can quietly cause thousands of dollars in water damage behind your walls. Cracked crowns, deteriorated mortar joints, and failed flashing are the leading causes of chimney-related leaks in Alpharetta homes - and they rarely announce themselves until stains appear on your ceiling. Our chimney repair team specializes in the specific problems Georgia's climate creates: freeze-thaw cycles that crack mortar, summer storms that loosen flashing, and years of red-clay dust that erodes sealant. We handle tuckpointing, crown rebuilding, flashing replacement, cap installation, and full brick restoration for both residential and commercial chimneys. Every repair starts with a thorough inspection and ends with photo documentation you can share with your insurer.
Alpharetta's chimney repair experts
Chimneys sit at the intersection of roofing and masonry - two trades that most contractors treat separately. Our team handles both, which means we catch problems that single-trade crews miss. A roofer might re-flash your chimney but overlook crumbling mortar joints three courses down. A mason might repoint the brick but skip the deteriorated cricket flashing on the back side. We address the entire chimney system as one unit because that is how water treats it. Based right here in Alpharetta, we have repaired chimneys on colonial homes in Windward, ranch-style houses near Webb Bridge Park, and commercial buildings along Old Milton Parkway. Our crew carries OSHA safety certifications, full liability insurance, and the specialized tools - from scaffolding rigs to mortar color-matching kits - that chimney work requires. We give honest assessments, show you exactly what we found, and only recommend work that genuinely needs doing.
Full-system chimney inspection and repair
Our chimney inspections follow a structured protocol that covers every component from the cap down to the flashing line. We check the chimney cap and spark arrestor for rust or damage, examine the crown for hairline cracks and pooling areas, probe mortar joints for depth of deterioration, test step flashing and counter-flashing seals, and inspect the interior flue liner for gaps or spalling. If the chimney has a cricket (the small peaked structure behind wider chimneys that diverts water), we check that too - crickets are notorious for collecting debris and developing hidden leaks. After the inspection, you receive a written report with photos, severity ratings, and a prioritized repair plan so you can address the most urgent items first and budget for the rest.
Licensed, local chimney repair technicians
Our technicians are not general handymen who occasionally work on chimneys. They are trained specifically in masonry repair, flashing installation, and waterproofing techniques that match chimney-specific demands. They understand that chimney mortar needs to be softer than the surrounding brick (a detail that inexperienced crews get wrong, leading to brick spalling), that flashing must be embedded into mortar joints rather than surface-mounted with caulk, and that crown repair compound needs to flex with temperature changes rather than crack like standard concrete. Because we are based in Alpharetta, we respond quickly, know the local building codes, and stand behind our work with a written warranty.
Crown repair and chimney waterproofing
The chimney crown is the concrete or mortar cap that covers the top of the chimney structure around the flue. It is supposed to shed water away from the chimney, but over time Georgia's temperature swings cause it to crack. Water seeps into those cracks, freezes in winter, and widens them further - a cycle that eventually lets moisture saturate the brick below. We repair minor crown damage with flexible sealant compounds designed for chimney use (not generic caulk, which fails within a year). For crowns with significant deterioration, we remove the old material and pour a new crown with a proper drip edge that overhangs the brick by at least two inches. After crown work, we apply a breathable siloxane waterproofing treatment to the entire chimney. This lets trapped moisture escape while preventing new water from entering - critical in Georgia's humid climate where chimneys rarely dry out completely between storms.
Tuckpointing and mortar joint restoration
Mortar joints take the worst beating on any chimney. They are softer than the brick by design, which means they absorb the stress of thermal expansion instead of letting the bricks crack. But that also means they wear out first. When mortar recedes more than a quarter inch from the brick face, water begins pooling in the joints and accelerating deterioration. Our tuckpointing process involves grinding out the damaged mortar to a consistent depth, cleaning the joints, and packing fresh mortar that matches the original color and composition. We use Type N mortar for most residential chimneys because it provides the right balance of strength and flexibility. For historic homes, we can match lime-based mortars to preserve the original character. Proper tuckpointing extends chimney life by decades and is significantly less expensive than full brick replacement.
Chimney flashing repair and replacement
Chimney flashing is the metal barrier where the chimney meets the roof surface. It consists of step flashing along the sides, counter-flashing embedded in the mortar joints, and a cricket or saddle behind wider chimneys to redirect water flow. When flashing fails, water runs down the chimney and behind your roof covering, soaking the decking and eventually staining ceilings below. We see flashing failures caused by dried-out sealant, nail pops that lift the metal, rusted steel flashing (we always replace with aluminum or copper), and improper original installation where flashing was surface-mounted with roofing cement instead of properly woven into shingle courses. Our replacement process integrates new step flashing with your existing roofing material, embeds counter-flashing into cleaned mortar joints, and seals everything with high-temperature sealant rated for the heat that chimneys generate. We also install or repair crickets on chimneys wider than 30 inches to prevent the debris and water buildup that causes most back-side leaks.
Chimney cap and spark arrestor installation
A missing or damaged chimney cap is one of the simplest problems to fix and one of the most expensive to ignore. Without a cap, rain falls directly into the flue, rusting dampers, staining fireboxes, and creating the musty smell that homeowners often mistake for a mold problem elsewhere in the house. Animals also enter uncapped flues - we have pulled raccoons, birds, and squirrels from Alpharetta chimneys more times than we can count. We install stainless steel caps with integrated spark arrestors that keep rain, animals, and debris out while allowing proper draft. For multi-flue chimneys, we install full-width caps that cover the entire crown, adding an extra layer of weather protection. Cap installation typically takes under an hour and provides years of protection for a modest investment.
