Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Flint Chimney Sweep Is Lilburn’s Preferred Chimney Repair Company
Lilburn homeowners don’t want a chimney company that quotes one number on the phone and another at the door. That’s not how we operate. Under The Garrison Standard, the code every Garrison Partners location follows, you receive a written price before a single tool comes off the truck. The number you approve is the number on the invoice. No line-item surprises after the fact.
Our repair crews are background-checked and uniformed, so when someone knocks, you know exactly who’s walking through the door. And when you call at 7 a.m. on a Saturday or 11 p.m. on a Tuesday, a live person answers. No voicemail tree, no callback form. That matters when you’ve got water staining the ceiling below your chimney in Lilburn and need a straight answer now.
Hank Delano leads our repair operations, and he’s particular about two things: documenting every problem with camera evidence and never selling a repair the homeowner can’t verify. If we tell you a flue liner is cracked, you’ll see the photo. If the mortar has years left in it, we’ll tell you that too. Our Chimney Repair team works that way on every job in Lilburn, from single-flue caps to full rebuilds.
Chimney Cap Replacement in Lilburn
Chimney cap replacement in Lilburn is one of the most common repairs we handle, and it almost always starts the same way: a homeowner on a wooded lot notices rain dripping through the damper or hears birds in the flue. Much of Lilburn sits under a heavy oak and pine canopy off Lawrenceville Highway and along the Camp Creek Greenway corridor, and that debris load is relentless. Pine straw piles on the crown, fills the cap’s mesh, and traps moisture against the flue tile. A standard single-flue cap replacement typically runs $340 – $620 in Lilburn, depending on flue size and whether the crown needs spot patching as part of the job.
What We Check Before Replacing a Cap
Before we quote a new cap, we inspect the flue tile below it. A rusted cap often hides a cracked crown, and if we replace the cap without addressing the crown, water keeps getting in. On a two-story off Killian Hill Road, our tech pulled a rusted-out single-flue cap clogged with pine straw, then found the chimney crown cracked and shedding water into the smoke chamber. We poured a new crown and set the cap properly, and the Level 2 camera sweep showed the flue liner was sound below the first-degree creosote line. That’s what a complete cap job looks like.
Choosing the Right Cap Material
We install stainless steel and copper caps from Olympia Chimney and Copperfield, sized to the exact flue dimensions. A cap with 5/8-inch mesh keeps birds and squirrels out while allowing the chimney to draft. The cheap caps sold at big-box stores rust through in two or three Georgia summers. We’d rather install one that lasts.
Chimney Liner Installation in Lilburn
Chimney liner installation in Lilburn costs $1,800 – $4,200 for a typical single-story home, and the biggest mistake we see is contractors quoting a liner before anyone has looked at the existing flue with a camera. In older Lilburn neighborhoods where homes were built in the 1970s and 1980s, clay tile liners develop cracks at the joints, and third-degree creosote glaze hides behind those joints. A new liner only solves the problem if someone confirms the real failure mode first.
When a Liner Is Actually Needed
The flue liner is the inner lining that channels smoke safely out of the house. You need a new one when the existing liner is cracked, separated, or too large for an efficient wood stove. We install DuraFlex stainless liners, which carry a lifetime warranty from the manufacturer and are sized to the appliance, not the masonry. If your chimney drafts fine and the camera shows intact tile with only first-degree creosote, you don’t need a liner. We’ll say that plainly.
From Camera Inspection to Completed Install
Every liner quote starts with a Level 2 camera inspection. You see the footage. We walk you through what it shows, then write a flat price for the liner, insulation, and top plate before work starts. The entire job usually takes one day. After the install, we run a second camera sweep to document the finished flue from top to bottom. That photo report is yours to keep.
Trusted Brands We Service in Lilburn
We don’t stock off-brand parts. Our repair techs work with Olympia Chimney caps, Famco dampers, Copperfield flashing, and DuraFlex liners, because these are brands a homeowner can verify independently. When you need a part for your Lilburn home, we don’t have to order it from a catalog and hope it shows up next week. We carry the common components on the truck, which means a cap replacement or mortar patch can often be completed the same day as the inspection. If a specific flue size or copper cap needs to be ordered, we tell you the turnaround before we quote the job.
Common Chimney Repair Problems We See in Lilburn Homes
- Rusted or bird-clogged caps. Wooded lots off Lawrenceville Highway and near Camp Creek Greenway shed pine straw and oak litter onto chimney crowns year-round. A clogged cap traps moisture against the flue and lets birds nest inside, which worsens spalling mortar before the homeowner notices anything.
- Cracked chimney crowns. Pine needles pile on the crown, hold water against the mortar, and freeze-thaw cycles do the rest. The leak hides until the damper sticks or brown staining appears in the smoke chamber.
- Liners quoted before anyone looked. Some contractors in the Lilburn area quote a liner over the phone without a camera inspection. Third-degree creosote glaze or a failed flue joint gets missed, and the chimney still doesn’t draft right after the new liner is in.
- Flashing leaks at the roofline. Lilburn’s heavy spring and summer rains expose weak flashing quickly. If the stain on your ceiling lines up with the chimney chase, the flashing is usually the first place we look.

FAQs About Chimney Repair in Lilburn
Every 25 to 35 fires, or once per burning season if you use the fireplace regularly from November through February. That’s not a sales pitch, it’s a creosote math problem. Wood fires deposit creosote on the flue walls, and in Lilburn’s humid, mild winters, that creosote builds faster than in drier climates because the flue never gets hot enough to burn it off cleanly. First-degree creosote brushes out easily. Third-degree creosote is a glaze that requires mechanical removal and can hide liner damage. If you want an exact schedule for your burn pattern, call (830) 251-4560 and we’ll build one with you after your first inspection.
A Level 2 camera inspection, a written photo report, and a flat repair quote. The camera goes from the firebox to the top of the flue, documenting every joint, every crack, and every creosote layer. You see the footage as we run it. If the chimney is sound, you get a clean report and no repair recommendation. If something needs work, the quote you receive is based on what the camera showed, not on a guess from the roof. Nothing is recommended without evidence you can see for yourself.
Yes, a properly fitted cap with 5/8-inch stainless mesh keeps pine straw, oak litter, rain, birds, and squirrels out of the flue. The key word is properly fitted. A cap that’s the wrong flue size or clamped loosely lets debris accumulate around the edges. On Lilburn’s wooded lots off Lawrenceville Highway and near Camp Creek Greenway, we see caps that were installed without checking the flue dimensions underneath. We measure the flue, match the cap to the appliance draw, and set it so water sheds away from the crown, not into the smoke chamber.
Minor mortar erosion on the exterior brick and first-degree creosote can usually wait until your next scheduled service, provided the chimney is drafting correctly and no water is entering the home. A cracked crown, a rusted-out cap, or a liner with separation at the joints cannot wait. Those are the failures that let water into the smoke chamber and chimney chase, and water is what turns a $600 cap replacement into a $2,400 rebuild. If you’re unsure which category your chimney falls into, call (830) 251-4560 for an inspection. We’ll tell you straight, and if it can wait, we’ll say so.
Yes, we install liners for freestanding wood stoves, fireplace inserts, and open fireplaces. Our standard liner is DuraFlex, a stainless steel system that carries a lifetime warranty from the manufacturer and is sized to the specific BTU output of your appliance. We stock common diameters and components locally for Lilburn jobs, so most liner installs happen within a week of the inspection. If you’re converting an open fireplace to a wood stove, the liner is the first thing we size, because an oversized flue will never draft efficiently. Call (830) 251-4560 for a free estimate and a written quote before any work starts.
