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 Norwalk’s Preferred Chimney Repair Company
Flint Chimney Sweep has operated since 2002 as part of the Garrison Partners family of independently owned chimney service companies. That means every Norwalk job follows The Garrison Standard: written price first, background-checked uniformed technicians on site, and a live person answering the phone 24/7. No voicemail trees, no callback forms.
Our crews know Norwalk’s housing stock well. The older streets off Pioneer Boulevard and the Civic Center area hold 1950s masonry chimneys with fireboxes that have seen sixty-plus years of use. The newer homes along the 605 corridor have their own issues: prefab flues, tight clearances, and flashing installed fast during the building boom. We’ve worked both.
Every repair we do in Norwalk includes a camera inspection and a photo report, so you see exactly what we found before you approve a dollar of work. Hank Delano runs our repair team, and he has one rule: no recommendation without pictures. If the camera doesn’t show it, we don’t sell it.
Written Pricing Before Any Work Starts
We don’t give a verbal range and then “discover” more once the scaffold is up. The number you approve in writing is the number on the invoice. This is non-negotiable at Flint Chimney Sweep, and it’s the single biggest thing Norwalk homeowners tell us they couldn’t get from other chimney companies.
The 365-Day Done Right Promise
Every chimney repair we perform in Norwalk carries a one-year written guarantee. If a covered repair fails within 365 days of the service date, we return and fix it at no charge. No argument, no second invoice, no fine print. That guarantee is printed on your work order.
Chimney Liner Installation in Norwalk
Chimney Liner Installation in Norwalk addresses the inner flue that channels smoke and combustion gases safely out of the house. In a 1950s tract home, the original clay tile liner is often cracked, spalled, or missing mortar joints by now, and that’s a real fire and carbon monoxide risk. We install DuraFlex stainless steel liners sized to your existing flue, and the job typically runs $1,800 – $4,200 depending on the flue height, roof access, and whether the old liner has to be broken out first.
How We Determine if You Need a New Liner
The camera tells the truth. We run a Level 2 inspection with a video scope, and the footage shows exactly what the flue looks like end to end. If the liner has a single vertical crack or missing joint, we recommend replacement. If the clay tile is intact and only the smoke chamber needs work, we say so and price that instead.
HeatShield as a Liner Option
For some Norwalk chimneys, a full stainless reline isn’t necessary. HeatShield is a ceramic resurfacing system that seals small cracks and gaps in an otherwise sound flue. It costs less than a DuraFlex reline and does the same job when the existing liner is structurally intact. We’ll show you the camera footage and let you decide which route makes sense.
Chimney Flashing Repair in Norwalk
Chimney Flashing Repair in Norwalk fixes the metal seal where the chimney meets the roofline. The LA Basin’s onshore marine flow keeps moisture on Norwalk roofs and masonry longer than inland cities, and flashing that would last 20 years in Pomona can fail in 8 to 10 here. We see pitted, corroded, or lifted flashing on Norwalk chimneys every week during the wet season. A proper flashing repair runs $250 – $640 for step and counter flashing replacement at the roofline.
Signs Your Flashing Is Failing
Water stains on the ceiling near the chimney, damp drywall in the attic, or rust streaks down the chimney exterior all point to flashing trouble. If the roofing cement around the flashing is cracked and pulling away, that seal is already compromised. In Norwalk’s damp marine air, we also check the flashing for electrolytic corrosion where dissimilar metals touch.
The Right Way to Fix It
We remove the old flashing, inspect the decking underneath for rot, and install new Famco or Copperfield flashing with a proper counter-flashing reglet cut into the mortar joint. No surface caulk, no roofing tar smeared over a leaking seam. The repair is sealed, water-shedding, and inspected with a water test before we pack up.
Trusted Brands We Service in Norwalk
We stock and install professional-grade chimney materials including DuraFlex, Famco, and Copperfield. We don’t use whatever the local supply house has on the shelf that week. The brand gets specified by the job: DuraFlex for stainless liners, Famco for caps and dampers, Copperfield for flashing and chase tops. For Norwalk customers, having these materials on our trucks means we can often complete a repair the same day we diagnose it. No waiting on a parts shipment from a distributor across the county.
Common Chimney Repair Problems We See in Norwalk Homes
- Marine-layer damp on masonry and flashing. Onshore flow off the coast keeps Norwalk chimneys wetter longer than inland cities. Crown cracks and flashing failures that would be minor in Cerritos become structural here if drainage isn’t corrected, not just patched.
- Spalling firebox brick in 1950s tract chimneys. The older homes off Pioneer Boulevard and the Civic Center area often have fireboxes where decades of heat cycling have popped the brick face. We repoint and rebuild these fireboxes rather than covering them with refractory panel band-aids.
- Second-degree creosote hiding in the smoke chamber. A brush sweep gets the flue, but the smoke chamber above the damper holds creosote that only a camera sees. We find third-degree buildup in Norwalk chimneys more often than owners expect, especially in homes where fires burn cool or wood isn’t fully seasoned.
- Chimney crown damage from standing water. Flat concrete crowns on older Norwalk chimneys crack along the surface, and once water gets in, freeze-thaw cycles aren’t the only problem. Even without freezing, the constant damp eats the mortar. We rebuild crowns with a properly sloped mix and a bond break that lets the crown move independently of the flue tile.

FAQs About Chimney Repair in Norwalk
An annual sweep is the baseline; repairs come when the camera finds damage. For most Norwalk homes, that’s every 3 to 5 years for flashing, crown, or mortar work, depending on how much you burn and how well the chimney drains. Marine-layer damp shortens those intervals here compared to inland cities. If the camera shows clean clay tile and tight mortar, we tell you to skip the repair and just book the sweep. Call (830) 251-4560 to schedule a chimney inspection and sweep.
Yes, most Norwalk chimneys never need a full rebuild. Repointing mortar joints, replacing flashing, rebuilding a crown, sealing spalled brick, and installing a new liner are all targeted repairs that preserve the original structure. Your flat price covers labor, materials, cleanup, and a written one-year guarantee. The price you approve before we start is the price you pay when we finish. Nothing changes mid-job, ever. Call (830) 251-4560 to get a written quote.
Third-degree creosote is common in Norwalk chimneys where owners burn unseasoned wood or fires run cool, and it’s the type that looks like hard, shiny tar glaze. A brush alone won’t remove it. We use professional creosote removal chemicals and mechanical methods to break it down, then a camera inspection confirms the flue is clear and shows whether the heat damaged the liner or mortar behind it. If the camera shows damage from the creosote, we price the repair separately and in writing. Call (830) 251-4560 to book a sweep with camera inspection.
A standard Level 1 inspection covers the accessible portions of the chimney with no special equipment, while a Level 2 uses a video camera to see the entire flue from top to bottom. We recommend a Level 2 for any Norwalk home that’s changing fuel type, has had a chimney fire, or hasn’t been inspected in more than two years. You get a photo report of everything the camera records so you can see the condition yourself. Call (830) 251-4560 and we’ll walk you through which level your chimney needs.
We show you the camera footage and explain what it means. If your chimney has a cracked flue liner, heavy creosote, or a blocked flue, that’s a measurable carbon monoxide and fire risk, and we tell you plainly. If the chimney is dirty but sound, we say that too. Nothing is recommended without photographic evidence you can see, and nothing is inflated to look worse than it is. You get a straight answer and a written price. Call (830) 251-4560 for a free estimate.
