You get a written price before any work starts, and every repair carries a written one-year guarantee. Call (762) 600-1468 to schedule an inspection.
Why Flint Chimney Co Alpharetta Is Lawrenceville’s Preferred Chimney Repair Company
We’ve worked on enough Lawrenceville chimneys to know the difference between cosmetic wear and structural failure, and we’re not going to sell you a rebuild when three tuckpointing passes will do. The homes here, especially the 1980s-2000s subdivisions off Riverside Parkway and the older bungalows near the downtown square, have very different chimney problems. Our technicians are background-checked and uniformed, so you know exactly who’s walking into your house. The price you approve before we touch the brick is the price on the invoice, no exceptions.
We dispatch from our Atlanta office, and scheduling for Lawrenceville is handled by a live person, not a voicemail tree, 24 hours a day. Hank Delano oversees every repair that leaves our shop, and the Garrison Standard is what we follow on every job: document the scope, price it clearly, stand behind it in writing. If a covered repair fails within 365 days, we return at no charge. That’s not a policy we invented for a website, it’s printed on the guarantee you’ll hold in your hand before we start.
Our Chimney Repair team has seen the same failures repeat across Lawrenceville: water pushing through crown hairline cracks, flashing that’s lifting at the roofline, and shared flues in attached homes creating hazards owners never see. That local familiarity means we know what to look for before it becomes a $4,000 rebuild. For a complete rundown of what we do and where, see Chimney Repair in Lawrenceville.
Styles & brands we work with
Chimney Liner Installation in Lawrenceville
Chimney Liner Installation in Lawrenceville means replacing the inner flue channel that carries smoke, heat, and combustion gases safely out of the house. In older attached homes here, especially those sharing a masonry stack, a cracked liner isn’t just an efficiency issue. It’s a pathway for exhaust from one unit to migrate into the next. We specify DuraFlex stainless liners and HeatShield resurfacing systems depending on what the inspection shows, and we’ll explain why one fits your chimney better than the other before you spend a dollar.
The Cross-Contamination Problem
Lawrenceville has a lot of attached and semi-attached housing from the 1980s and 1990s. When two units share one masonry stack, a cracked flue liner or a failing damper in one unit lets exhaust from the other unit drift sideways into your living space. That’s carbon monoxide risk, not a draft complaint. Our techs worked a two-unit home off Grayson Highway where a neighbor’s gas furnace vented into a shared stack. After finding a cracked liner and heavy third-degree creosote glaze in the shared smoke chamber, we installed a HeatShield liner and rebuilt the crown on the spot. That job prevented a genuine carbon monoxide problem inside the adjacent unit.
When You Need One
You need liner work when a Level 2 inspection shows cracks, gaps, or deterioration in the existing flue. In Lawrenceville, the wet winters and storms accelerate rust in steel liners and erosion in clay tile liners. You’ll also need relining if your home still has an unlined masonry chimney venting a gas appliance, a condition that violates current code. A liner install in Lawrenceville typically runs $1,800 – $4,200, depending on the flue height, access difficulty, and whether we’re installing a full stainless system or resurfacing the existing masonry.
Chimney Flashing Repair in Lawrenceville
Chimney Flashing Repair in Lawrenceville is the fix for water leaking in where the chimney meets the roofline. Flashing is the metal skirt, usually galvanized steel, aluminum, or copper, that seals the joint between roof and brick. In Lawrenceville’s climate, where summer thunderstorms dump heavy rain and winter brings long damp spells, flashing loosens, pulls up, or gets pounded until the seal fails. Water then tunnels down the chimney chase, soaking the firebox and smoke chamber. You won’t always see a stain on the ceiling. Sometimes the first sign is a musty fireplace smell in August.
What We Check
A flashing repair should not be a “put more caulk on it” job. We pull the shingles back far enough to see how the flashing was originally lapped, check for nail holes that have pulled free, and inspect the counterflashing embedded in the mortar joints. If the chimney crown is also failing, we’ll tell you because new flashing under a cracked crown just moves the leak inside. Flashing replacement in Lawrenceville usually runs $350 – $900, depending on roof pitch, chimney size, and whether we need to cut new counterflashing into the brick.
What It Prevents
Leaky flashing is the quiet failure. Water gets into the smoke chamber and starts eating at the firebox refractory panels. By the time you see rust on the damper or brown staining on the hearth, you’re often looking at a full firebox rebuild instead of a flashing repair. That’s a $1,500 problem becoming a $4,000 problem, and no chimney sweep should let you find it that way.
Trusted Brands We Service in Lawrenceville
We stock and install professional-grade chimney materials that trade pros know by name: DuraFlex liners, HeatShield flue resurfacing systems, Gelco crown coat products, and Olympia Chimney caps and dampers. These aren’t big-box substitutes. We keep the most common Lawrenceville sizes on our trucks, which means most liner and cap work doesn’t have to wait on a parts delivery. You can verify every product we install, and we’ll put the spec sheet on your invoice if you want it.
Common Chimney Repair Problems We See in Lawrenceville Homes
- Missing or failed chimney crowns. Older downtown Lawrenceville bungalows, particularly streets off the square, often have little more than a mortar wash where a proper concrete crown should be. Georgia’s rainy winters soak that masonry, and the freeze-thaw cycle, even a mild one, cracks it further every year.
- Spalled brick faces. Clay-heavy soil around Lawrenceville holds moisture against foundation and chimney bases, and the bricks themselves absorb that water. When the outer face of a brick pops off, water and insects now have an open path into the stack.
- Shared-flue contamination. In attached 1980s-2000s subdivisions, two units sometimes vent into one flue or share a smoke chamber. A cracked liner in one side lets the neighbor’s furnace exhaust push into your side, and you might never see or smell it until a detector goes off.
- Flashing rot and seal failure. Summer thunderstorms here arrive hard and fast. Old tar and caulk flashing repairs fail quickly under that kind of beating, and the leak migrates into the firebox and smoke chamber faster than you’d expect.

FAQs About Chimney Repair in Lawrenceville
A shared stack with two separate flue liners is usually fine until one liner cracks or a separator fails. At that point, combustion gases from your neighbor’s furnace, water heater, or fireplace can leak sideways into your flue instead of going up and out. In Lawrenceville’s denser 1980s-2000s attached housing, this is a common finding during Level 2 inspections. The fix is usually a HeatShield resurfacing or a DuraFlex liner that seals the damaged path. If you share a wall with an attached unit and don’t know the condition of the flue on the other side, call (762) 600-1468 and we’ll inspect it.
Clay soil expands when wet and shrinks when dry. That seasonal movement, repeated year after year, stresses the chimney foundation and transmits micro-movement up the masonry. A rigid concrete or mortar crown sitting on top of that moving stack develops hairline cracks, and those cracks are exactly where rainwater enters. Once water works into the crown, it follows gravity down into the brick and mortar joints. A proper crown repair in Lawrenceville addresses both the crown itself and the slip joint that lets the crown flex with the stack.
Water damage in these older homes almost always starts at the crown or flashing and gets into the smoke chamber, where it sits against the firebox panels and liner. In Lawrenceville bungalows near the square, where many chimneys lack a proper poured crown, our techs routinely find soaked mortar, rusted dampers, and firebrick that’s begun to erode after a single heavy rain season. The outside of the chimney can look perfectly fine while the inside is degrading. That’s why a Level 2 camera inspection matters, especially after Georgia’s storm season.
Yes, if the separation wall or the masonry between your flues has cracked or eroded. Heat from a neighbor’s heavy fireplace use can dry and crack the mortar in a shared smoke chamber wall, and that crack becomes a gas pass-through. You won’t necessarily see smoke; you may notice a strong creosote or gas odor in your fireplace even when you haven’t used it in months. This is precisely why we recommend inspecting both units when one side of an attached Lawrenceville property reports chimney problems.
Humidity enters the flue during damp weather and binds with creosote deposits, causing them to swell and harden into a thick, tar-like glaze. In Lawrenceville, where summer thunderstorms are followed by 90-degree heat, the chimney acts like a kiln. That baked creosote is harder to remove and more flammable if you light a fire in the fall. We recommend a sweep before the first fire of the season, especially if your fireplace has seen little use since spring. Call (762) 600-1468 and we’ll put you on the schedule.
