Why Hearthstone Chimney Co. Is McDonough’s Preferred Chimney Repair Company
We’ve been serving Henry County since 1984, long before the I-75 corridor turned McDonough into one of Atlanta’s busiest exurbs. That longevity means something here. We’ve watched the subdivisions go up, we’ve tracked how those builder-grade systems age, and we’ve built relationships with homeowners who’ve called us back for fifteen and twenty years.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict. No jargon, no scare tactics. Most repairs in McDonough finish in one visit because our trucks carry the parts and materials suited to this market’s specific needs - from Chimney Liner & Rebuild - McDonough services using DuraFlex liners for refractory panel replacements, to Famco dampers for the chase assemblies common in 1990s and 2000s construction, and Olympia Chimney components for the prefabricated systems that dominate local housing stock.
Calls are answered by a live person 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. When your chase cover has rusted through and water’s been sheeting down inside the framing for two seasons, you don’t want to leave a message and hope.
Every job carries our 90-Day Done Right Promise in writing: if it’s not right, we come back. No paperwork to file, no argument. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it. We’ve operated this way for over 42 years because we plan to be here in thirty more.
Our Chimney Repair Services in McDonough
Mortar Repointing
True masonry chimneys are rarer in McDonough than newcomers expect. When we do find them - typically on older homes near the historic downtown or custom builds in the Kelleytown area - the mortar joints often need grinding out and repacking with fresh, properly matched mortar. Georgia’s freeze-thaw cycles are milder than up north, but our humid subtropical climate lets moisture penetrate and expand behind the brick face, popping the surface off in sheets. Repointing a standard McDonough masonry chimney runs $450-$850. We color-match the mortar to existing joints so the repair doesn’t shout.

Spalling Brick Repair
Spalling shows up when bricks have absorbed enough moisture that their faces flake or crumble. In McDonough, we see this most often on chimneys attached to pre-1990 homes or on custom masonry in neighborhoods like Ola Road and the older sections near Highway 81. The repair involves removing damaged brick, addressing the moisture source - usually failed flashing or a missing chimney cap - and replacing with matching units. A localized spalling repair typically costs $350-$700. If the damage is widespread, we may recommend our Chimney Cap & Crown in McDonough service to prevent recurrence.

Chimney Waterproofing
McDonough’s long, damp summers are harder on chimneys than our mild winters. Water gets in through porous brick, deteriorated crown wash, or gaps at the roofline, then sits through months of humidity without drying out. Our waterproofing treatment uses vapor-permeable sealers that let the masonry breathe while blocking liquid water - critical in a climate where trapped moisture causes more damage than freeze. A typical waterproofing job on a McDonough home runs $400-$750 depending on chimney size and accessibility. We also handle Fireplace Services in McDonough if water damage has reached the firebox or damper assembly.

Flashing Repair
Flashing is the sheet metal where your chimney meets the roof, and it’s the single most common leak source we find in McDonough. The combination of thermal expansion, UV exposure, and the occasional severe thunderstorm works the seal loose over time. In the subdivisions off Jonesboro Road, we’ve replaced flashing on homes where the original installer used caulk instead of proper step flashing, guaranteeing failure within a decade. Repair costs range from $300-$600 for straightforward reflashing to $800-$1,200 if the surrounding decking has rotted. We use copper or galvanized steel, never the thin aluminum that some crews slap on.

Trusted Brands We Service in McDonough
Our trucks stock professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - the brands that hold up in Georgia’s humidity and heat. For McDonough’s prefabricated fireplace market, this means we can replace a rusted chase cover with a proper Gelco or Famco unit in stainless steel or copper, not another galvanized piece that’ll fail in eight years. We don’t substitute builder-grade parts to hit a lower price. The number on your estimate is the number on your invoice, and the parts we use are the parts we’d put on our own homes.
Common Chimney Repair Problems We See in McDonough Homes
- Rusted-through chase covers on prefabricated fireplaces. In the large subdivisions off Flippen Road and throughout the 30252 and 30253 ZIP codes, the original galvanized sheet-metal chase covers installed during the 1990s and 2000s building boom have reached end of life. Water sheets down inside the chase unseen, rotting framing and pooling on the firebox floor - usually discovered during what the homeowner booked as a routine cleaning.
- Failed top-sealing dampers from humidity exposure. McDonough’s humid subtropical climate corrodes the mechanisms on metal dampers even when fireplaces sit unused through long, damp summers. Many homeowners only discover the failure when they light their first fire of the season and smoke fills the room.
- Crumbling refractory panels in factory-built fireboxes. Heatilator, Superior, and Majestic units installed during Henry County’s rapid growth period are now 15-25 years old. The refractory panels crack and erode, exposing the metal firebox to direct flame - a condition that violates manufacturer safety standards and most homeowners’ insurance policies.
- Flashing separation at the roofline. The thermal cycling of Georgia’s hot summers and occasional cold snaps, combined with the wind-driven rain of spring thunderstorms, works flashing loose faster here than in more temperate climates. We find active leaks on homes barely fifteen years old.

Yes - we work across 30252 and 30253, from the historic downtown area to the subdivisions off Jonesboro Road, the Flippen Road corridor, Lake Dow, Kelleytown, and the Ola Road area. The newer the subdivision, the more likely we’re dealing with prefabricated fireplace systems rather than masonry, and we’re equipped for both.
Yes. A live person answers our phones 24 hours a day, 7 days a week, including weekends and holidays. If you have an active water leak, a damaged firebox creating a safety hazard, or a chimney damaged by storm or fallen limb, we’ll dispatch a technician. Not every after-hours call requires immediate dispatch - sometimes we can talk you through temporary measures - but the option is there.
McDonough pricing typically runs 10-15% below comparable repairs inside the Perimeter, mainly because our technicians aren’t burning Atlanta commute time and fuel surcharges don’t apply. For the prefabricated systems common here, parts availability is actually better - we stock the DuraFlex, Famco, and Olympia Chimney components this market uses most, and we offer Chimney Cleaning & Sweep in McDonough to keep them running safely. You’ll get an exact written estimate before any work begins.
Every repair is backed by our 90-Day Done Right Promise in writing: if anything about the repair fails or isn’t right, we return and make it right with no paperwork and no argument. Materials carry their manufacturer warranties as well - Gelco chase covers, for instance, come with their own coverage terms. The Promise is our commitment, not a hedge. We’ve honored it for over 42 years. Call (844) 803-1545 for a free estimate and we’ll put the details in writing before we start.
