Warning signs
Call us if you notice any of these
Most problems give a warning first. Catching them early keeps a small fix from turning into a big one.
- A strong smoky or musty smell from the fireplace
- Smoke drifting back into the room instead of rising
- Water stains on the ceiling or wall near the chimney
- Crumbling brick, loose mortar or flakes in the firebox
- Clothes taking longer than usual to dry
- Visible dust or mold around air vents and registers
Services
Chimney and duct work we do
From a routine sweep to rebuilding a damaged chimney, we handle the full venting system in your home: the chimney and fireplace, the liner that carries exhaust out, the air ducts that move heat and cooling through your rooms, and the dryer vent that carries lint and hot air outside. Choose a service below to see what the work involves and when it makes sense.
Book before the first cold night
Fall is the busiest time for chimney sweeps. Get your sweep and yearly inspection on the calendar before you light the first fire.
Inspections
Three levels of chimney inspection
The NFPA 211 standard calls for a yearly inspection. Which level you need depends on what has changed since the last one.
-
Level 1
Annual check
For a chimney and appliance that have not changed and will be used the same way: the readily accessible parts of the chimney, the flue and the connection, checked for soundness, blockages and deposits.
-
Level 2
Camera inspection
When something changed — a new stove, insert or boiler, a fuel switch such as oil to gas, the sale of the home, or a chimney fire, storm or quake. Adds a video scan of the whole flue and the accessible attic, roof and crawl spaces.
-
Level 3
Concealed areas
Only when a Level 1 or 2 points to a hidden hazard that cannot be checked any other way: parts of the chimney or building are opened to reach it.
How it works
Clear steps. Your approval first.
-
Book a visit
Call or send a short request: the fireplace, stove, boiler flue or vents you need looked at, and what you have noticed.
-
We inspect first
The crew lays down drop cloths, checks the system top to bottom and runs a camera up the flue where it is needed.
-
Written price, your call
You see photos of what we found and get the price in writing. Work starts only after you say yes.
-
Clean, fix, report
We sweep, repair or reline, vacuum up with HEPA filters and leave you a photo report of the finished work.
Straight pricing
No bait prices. No surprises.
-
Written price first
Before any work starts, you get a written price for exactly what we plan to do. Nothing begins until you approve it.
-
Photos of what we found
We photograph the problems we find inside the chimney, vent or ductwork so you can see the condition for yourself.
-
No surprise add-ons
If we find something new during the job, we stop and explain it before doing anything more. The approved price covers the approved work.
About us
Chimney and Vent Work Explained Clearly
ClearStack Chimney Service cleans, inspects and repairs chimneys, fireplaces, air ducts and dryer vents for homes across Brooklyn. Much of our work is in the southern and central parts of the borough, where attached rowhouses, older brick chimneys and converted boilers are common. Every job starts with a look before we touch anything. Our certified technicians check the flue, the crown, the damper and the connections, then explain what they found in plain terms. If something needs repair, you get a written price first, along with photos so you can see the problem yourself. If a cleaning is all you need, that is all we recommend. We follow the NFPA 211 standard, which calls for chimneys, fireplaces and vents to be inspected once a year, and we use the inspection level that fits your situation. The goal is simple: a system that vents safely, a home left as clean as we found it, and answers you can understand.
More about how we workWhere we work
Every kind of home in Brooklyn
-
Rowhouses and brownstones
Attached homes often share chimney walls with neighbors and have tall, narrow flues that are hard to reach. We plan roof access carefully and check how your flue relates to the building next door.
-
Detached homes
Detached houses usually have more exposed chimney masonry, so the crown, flashing and cap take more weather. Inspections focus on water entry as well as the flue itself.
-
Co-ops and apartment buildings
Larger buildings involve shared boiler chimneys, building management and access scheduling. We coordinate with supers and managers and keep work organized around residents, especially during heat season.

FAQ
Common questions
How often should my chimney be inspected?
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. The inspection tells you whether a sweep or any repair is actually needed.
What are the different inspection levels?
A Level 1 inspection is for a system that has not changed. Level 2 is used when something changes, such as a new appliance or a switch of fuel, or when the home is sold. Level 3 is needed when a hidden hazard can only be reached by opening part of the chimney or building.
We are converting our boiler from oil to gas. Does the chimney need work?
In New York City the chimney has to be evaluated as part of an oil-to-gas conversion. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue.
When is the best time to schedule chimney service?
Late spring and summer are usually the easiest times. New York City's heat season runs from October 1 through May 31, so having the chimney checked before October helps you avoid problems once the heat is running.
Do I really need my air ducts cleaned?
Not always. The EPA advises cleaning when there is substantial visible mold growth, vermin, or excessive dust and debris. It also notes that duct cleaning has not been shown to prevent health problems. We will tell you honestly whether your ducts need it.
Why does dryer vent cleaning matter?
According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. A clogged vent also makes the dryer work harder and take longer to dry clothes.
Do you use chemical treatments in air ducts?
We do not apply chemical treatments by default. The EPA advises caution with them, so if one is ever considered, we will explain what it is and why before anything is used.
