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 Derby’s Preferred Chimney Inspection Company
Flint Chimney Sweep has operated under The Garrison Standard since 2002 as part of the Garrison Partners family of independently owned chimney service companies. Our crews show up in uniform, background-checked, and the person on the phone is a live human being at any hour of the day or night. We don’t use voicemail trees and we don’t make you wait until Monday morning to ask a question about your Derby chimney.
What Derby homeowners tell us they value most is the written price before any work begins. The number on your invoice is the number you approved before tools came off the truck. And every repair we do, including any fix we recommend during a Chimney Inspection, carries the 365-Day Done Right Promise: if a covered repair fails within one full year, we return at no charge and make it right.
Level 2 Chimney Inspection in Derby
A Level 2 Chimney Inspection in Derby typically costs $325 to $425 and includes everything a Level 1 does plus video scanning of the flue interior, attic access, and crawlspace or basement checks. This is the inspection we recommend for most Derby homes because the river-corridor damp drives moisture into exterior masonry, and the camera is the only honest way to see what is actually happening inside the flue liner, smoke chamber, and firebox without guessing. Any time a property changes hands, a new appliance is installed, or a storm drops a branch on the cap, a Level 2 is the correct call.
Camera Inspection
We run a push camera up the full length of the flue and record the whole pass. You’ll get still photos with notes so you can see exactly what we saw, not a summary someone wrote up later from memory.
Flue Inspection
This covers the liner, the smoke chamber above the damper, and the chimney crown up top. In Derby we pay special attention to spalled flue tiles and eroded mortar joints because the Housatonic and Naugatuck river valleys load exterior chimneys with wind-driven rain all winter.
Chimney Leak in Derby
A Chimney Leak in Derby is usually traced to a cracked crown, failed flashing at the roofline, or a spalling brick face letting water saturate the chimney structure, and diagnosing it correctly costs $189 to $325 depending on how much of the system we need to examine. We don’t guess at leaks. We trace them with the camera and a water test where it’s appropriate, then put the fix in writing with a price before we touch anything. In Derby’s riverside sections, especially around older homes with exterior stacks, we see leak calls all winter because rain rides the wind off the water and hits the chimney sideways.
Chimney Crown and Flashing Work
The crown is the concrete cap at the top of the chimney. When it cracks, water drops straight into the flue and soaks the firebox mortar. Flashing is the metal at the roof line. Both fail more often in Derby than in inland towns because of the moisture load off the river valleys.
Repair or Reline Decisions
If the leak has reached the flue liner and cracked it, you may need HeatShield resurfacing or a DuraFlex reline. We will tell you when the camera shows something that can wait. We will also tell you when it cannot.
Trusted Brands We Service in Derby
We install and service HeatShield, Gelco, Olympia Chimney, and Famco products, and we keep common parts stocked for faster turnaround on Derby jobs. If your chimney needs a crown sealer, a top-mount damper, or a stainless steel cap, we will spec the right brand for your system and put it in the written quote. You can verify any of these products independently, and we will never substitute a cheaper option without telling you first.
Common Chimney Inspection Problems We See in Derby Homes
- Spalling brick and cracked crowns on exterior stacks. River-corridor moisture works into the outer brick face, freezes, and pops the face off in flakes. Left alone, water reaches the interior and the bill grows.
- First-degree creosote flakes in wood-burning fireboxes. Derby homes burn a lot of oak and maple. Even light seasonal use leaves deposits that a visual look will catch but a camera inspection will confirm.
- Cracked exterior flue liner tiles. The camera sees these long before smoke or smell does. A hairline crack in a liner tile is a carbon monoxide path, not a cosmetic issue.
- Failed flashing at the roofline. Older Derby homes settle, and flashing pulls away from the brick. That leak often shows up as a stain on the ceiling near the fireplace, not as a wet chimney.

FAQs About Chimney Inspection in Derby
Not necessarily. If you burn fewer than a dozen fires a year in a properly drafting fireplace, a Level 1 look during your cleaning is usually enough, and you can likely stretch the full Level 2 camera inspection to every two or three years. The exception is weather: Derby’s river-corridor storms knock brick faces loose and crack crowns, so after any major wind event you should at least have the cap and crown checked visually. Call (830) 251-4560 and we will give you a straight answer on what your chimney actually needs this year.
A Level 1 inspection is a visual check of the accessible parts of the chimney during a routine sweep, while a Level 2 inspection adds video scanning of the flue interior plus attic and crawlspace checks. If you’ve had a chimney fire, changed appliances, bought the house, or had a storm drop debris on the chimney, you need a Level 2. Most Derby homes with exterior masonry stacks and clay liners should get a Level 2 every three years because the river damp ages liners faster than dry inland air. The phone line is (830) 251-4560, and we’ll tell you which level fits your situation before booking.
The price we quote before we arrive is the price you pay unless you approve additional work in writing. A Level 1 in Derby runs $189 to $249. A Level 2 runs $325 to $425. That written number covers the inspection and the photo report, period. If we find damage that needs repair, we quote that separately in writing and you decide before any repair work starts. Call (830) 251-4560 for your exact quote today.
What you are seeing is glazed creosote, which is third-degree creosote and it is flammable, but the bigger risk on a Derby chimney is what you can’t see: the same glaze coating the flue liner above the damper. If it ignites, it burns hot enough to crack clay liners and start a chimney fire. We inspect it with the camera, show you the photos, and tell you honestly if cleaning will handle it or if HeatShield resurfacing is the right call. Call (830) 251-4560 and we’ll take a look.
Every one to three years, depending on how much you burn and how dry your wood is. Derby’s river-corridor damp means exterior flues stay cooler, and cooler flues condense creosote faster, so a house that would go two years inland may need yearly cleaning here. But not every chimney does. We will tell you plainly when cleaning can safely wait, and we never recommend a sweep just to fill a schedule. Call (830) 251-4560 for an honest schedule based on your actual burning habits.
If you need a chimney inspection in Derby, call Flint Chimney Sweep at (830) 251-4560. You’ll get a written estimate before any work starts, a live person on the phone, and a full year of warranty coverage on every repair we do.
