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 Lennox’s Preferred Chimney Repair Company
Lennox is a compact residential pocket east of the 405 and south of the 105, and the homes here share a pattern: dense older single-family construction built decades ago, with masonry chimneys that have weathered the same mild, damp coastal air for years. We know these houses. When a Lennox homeowner calls about water staining near the chimney, we don’t start with a guess. We run a camera up the flue, photograph what we find, and put the repair price in writing before we book the work.
Hank Delano leads the team at Flint Chimney Sweep, and the discipline shows in how we operate. Every repair carries the 365-Day Done Right Promise: a written guarantee valid for one full year from the service date, with a free return visit if a covered repair fails. That’s not a marketing line. It’s the Garrison Standard, the same code every Garrison Partners location follows. Lennox homeowners who have been burned by no-show crews or price moves at the door tend to appreciate a company that documents what it will do, what it costs, and how long it stands behind the work. We also dispatch background-checked, uniformed technicians, so you know exactly who is walking through the door.
Our Lennox customers call with the same three problems over and over: cracked chimney crowns, flashing that has separated from the roofline, and flue liners hiding third-degree creosote behind what looks like a light dusting. We stock the materials to address all three: DuraFlex liners, HeatShield resurfacing compounds, and Olympia Chimney flashing products. That means a repair scheduled in Lennox doesn’t wait on a parts shipment from across the country.
Chimney Flashing Repair in Lennox
Chimney Flashing Repair in Lennox is one of the two most common repairs we do, because the flashing that seals the joint between chimney and roof takes a beating in this climate. Lennox sits close enough to the coast that the air carries persistent moisture, and the daily thermal cycling, warm afternoons followed by cool, damp nights, works the metal loose over time. Once flashing pulls away even a quarter inch, water finds the gap and seeps down along the chimney chase, soaking the framing and the ceiling below. You won’t always see the leak immediately, which is why water stains near the chimney often show up a season after the flashing first failed. A full flashing replacement in Lennox, including new step flashing and counter-flashing sealed properly, typically runs $425 – $1,150.
What we check before quoting
Before we quote flashing work in Lennox, we inspect the roof joint from above and the attic from below. If the flashing is intact but the sealant has failed, the fix may be a reseal rather than a replacement, and we’ll tell you that plainly. We don’t recommend work the photos don’t support.
Why flashing fails in this area
Older Lennox homes often have original flashing that was installed with materials not rated for decades of coastal moisture exposure. The metal corrodes, the fasteners back out, and the sealant dries into brittle flakes. Our crews replace it with materials from Olympia Chimney, specified for the job, not by margin.
Chimney Crown Repair in Lennox
Chimney Crown Repair in Lennox is our other most frequent call, and it follows directly from the age of the housing stock here. The crown is the concrete or mortar cap that sits on top of the chimney, shedding water away from the flue and the masonry below. In Lennox’s older homes, many crowns were poured decades ago with mortar mixes that crack under years of mild-but-constant damp air. Once a crown cracks, water gets into the chimney structure itself, spalling the brick faces and deteriorating the mortar joints in the smoke chamber. A crown repair or recast in Lennox usually falls between $350 and $1,800 depending on the extent of the damage and whether we are patching or rebuilding the crown form entirely.
Signs your crown needs work
Crumbling mortar at the top of the chimney, pieces of concrete in the firebox, or water in the smoke chamber after rain all point to a compromised crown. We photograph the crown during inspection so you can see the cracks we are quoting against, before you approve anything.
What repair involves
For a recast crown, we remove the failing material, inspect the flue liner beneath it, and pour a new crown with a proper drip edge that sheds water away from the masonry. We use HeatShield resurfacing compounds when the flue liner itself shows surface cracking, and we’ll show you the camera footage that justifies the work.
Trusted Brands We Service in Lennox
We install and repair with professional-grade chimney products only, including DuraFlex, HeatShield, and Olympia Chimney. These are the same brands commercial sweeps and masons specify, and we stock common parts locally so Lennox jobs don’t wait on cross-country shipping. Whether it’s a HeatShield crown coat, a DuraFlex flue liner replacement, or a full flashing reset with Olympia components, the material gets chosen for the job. You can verify the product independently before you approve the repair, and the brand is named in writing on your quote.
Common Chimney Repair Problems We See in Lennox Homes
- Cracked crowns from decades of coastal air. Older Lennox chimneys often have crowns that were poured before modern drip-edge standards. Damp air cycles open hairline cracks into water channels, and the masonry below starts spalling within a season or two.
- Flashing that pulls away from the roofline. The thermal cycling near the coast works sealant and fasteners loose. We see slow leaks that have been soaking the framing for months before the homeowner notices a stain on the ceiling drywall.
- Hidden third-degree creosote behind a light first-degree dusting. Even in a warm climate, occasional fires deposit creosote. When the flue is rarely used, the visible layer looks thin, but a camera inspection often reveals tar glazing deeper in the liner that a standard brush cannot touch.
- Skipped inspections because Lennox winters stay warm. Homeowners reason they don’t burn enough to justify an inspection, so nests, cracked liners, and open flashing go unnoticed until a Level 2 inspection, often after a real problem has already started.
Our tech got a call from a homeowner on a quiet residential block in Lennox for what they thought was just a routine sweep before winter, but the Level 1 inspection turned up a cracked chimney crown and open flashing joints where water had been seeping into the smoke chamber for at least a season. That pattern repeats across this area. The mild climate masks problems, not prevents them. We sealed the crown, reset the flashing, and ran a camera down the flue liner to confirm no third-degree creosote was hidden behind the visible first-degree build-up. We quoted the crown and flashing repair at a flat price before we booked the return visit, sent the homeowner the inspection photos that same evening, and told them the actual sweep could safely wait until the repair was cured. That’s how we work in Lennox: evidence first, price in writing, and a straight answer on what can wait.

FAQs About Chimney Repair in Lennox
Yes, and the reason has nothing to do with creosote from heavy use. In Lennox’s mild damp climate, the risk is water intrusion through cracked crowns and failed flashing, plus animal nests and cracked liners that form whether you burn or not. An annual inspection in Lennox is how you catch those problems before the water reaches the framing.
You cannot tell from looking up from the firebox, because third-degree creosote forms as a tar glaze inside the flue liner, often behind a thin first-degree dusting at the top. The only way to confirm it in Lennox is a camera inspection. We run a camera down the flue on every inspection, photograph what we find, and if we see glazed tar, we’ll show you the image on the report and quote removal accurately. Call (830) 251-4560 if you want that documented.
It could be either, and it could be both. Flashing failure lets water in where the chimney meets the roof; a cracked crown lets water in from the top and down through the masonry. In Lennox’s older homes, we often find both at once, because the same years of coastal damp have worked on the top cap and the roof joint. We’ll diagnose it with a top-down and a bottom-up inspection and send you photos that show exactly where the water is getting in before we quote a repair.
Sometimes. Simple flashing reseals and minor crown patching can often be handled the same day in Lennox if the materials are already on the truck, which they usually are. Larger jobs, such as a crown recast or flue relining, get scheduled for a return visit once we have laid out the written quote and you’ve approved it. We never rush a repair to squeeze it into an inspection slot, and we don’t promise same-day service we can’t deliver.
You get a full inspection: a top-down look at the crown, flashing, and masonry; a bottom-up camera run through the flue liner and smoke chamber; and photos of everything we find. We send you the photo report the same evening and walk you through the images. No repair gets recommended without camera evidence you can see for yourself, and the quoted price is in writing before we book any work. Call (830) 251-4560 to schedule an inspection in Lennox.
