Chimney and Masonry Services in Crown Heights
Ten services, four groups, one rule: we look inside the flue and photograph the stack before we recommend anything. Here is how the work is organised and which service fits which problem.
What chimney services does a typical Crown Heights rowhouse need?
A rowhouse with a working fireplace needs an annual sweep and inspection, and a rowhouse with only a gas boiler still needs the flue inspected every year. Beyond that, the common jobs on Crown Heights stacks are repointing washed-out mortar joints, recasting a cracked crown, replacing failed flashing with copper, and relining old clay or brick flues in stainless steel when the fuel or the appliance changes.
How the Work Is Grouped
Our services fall into four groups. Chimney Repair covers the masonry and weatherproofing of the stack itself: leaks, crowns, mortar joints and flashing. Cleaning and Inspection covers everything that happens inside the flue, from a routine sweep to a camera scan. Installation covers liners and caps, the two components that most often need adding to an older Brooklyn chimney. Emergency work is leak repair that cannot wait for a scheduled slot.
If you already know what you need, the list below says what each service involves. If you only know the symptom, skip to the section after it.
Every Service, in One Line Each
These are the jobs our crew actually does on the stacks around Eastern Parkway, with the material or method that defines each one.
- Chimney Leak Repair: a water test and roof-level inspection to pinpoint entry, then the specific repair that closes it, whether that is the crown, the flashing or the brick itself.
- Chimney Crown Repair: removal of a cracked or tar-patched crown and a new cast-in-place crown poured with a drip edge that projects past the brick.
- Chimney Tuckpointing: joints raked to sound depth and refilled with Type N mortar, the softer mix that old brick and limestone need so the brick does not spall around a harder joint.
- Chimney Flashing Repair: copper step and base flashing with lead counter-flashing set into a cut reglet, replacing the tar and membrane patches we usually find.
- Chimney Sweep: full mechanical cleaning of the flue, smoke shelf, smoke chamber and firebox, with a damper check and a look at the firebox mortar while we are there.
- Chimney Inspection: a Level 1 inspection with the sweep, or a Level 2 camera inspection when the property is being sold, the fuel is changing or there has been a fire or a storm event.
- Creosote Removal: chemical treatment and mechanical removal of glazed creosote that has hardened on the flue walls past the point a standard sweep can clear.
- Dryer Vent Cleaning: rotary cleaning of the full vent run from the dryer to the exterior hood, with the hood flap and screen checked for blockage.
- Chimney Liner Installation: a stainless steel flue liner sized to the connected appliance, insulated where the installation calls for it, with a new top plate and cap.
- Chimney Cap Installation: a stainless steel cap with a spark arrestor screen fitted to the flue tile or to a new top plate, sized so it does not choke draft.
Chimney Leak Repair
Water near a fireplace has four possible sources, and sealing the wrong one wastes money. We trace the actual path on Crown Heights rowhouses and pre-war buildings, then fix that path with the right material.

The crown is the slab that seals the top of the chimney around the flues, and on most Crown Heights stacks it is a thin mortar wash that cracked years ago. We rebuild crowns as reinforced cast-in-place slabs with an overhang and drip edge, so water sheds away from the brick.
Learn more →Chimney Tuckpointing
Mortar joints are the sacrificial part of a chimney: they are meant to wear before the brick does. We grind out failed joints on Crown Heights stacks and repoint them in a lime-rich Type N mortar that matches the original in strength and color.
Learn more →Chimney Flashing Repair
Flashing is the metal that bridges the chimney and the roof, and it fails quietly under layers of tar. We cut out the old work, install new base flashing in copper or aluminum, and let counter-flashing into the brick joints so the seal does not depend on caulk.
Learn more →Chimney Sweep
A proper sweep removes soot and creosote from the firebox to the flue cap and ends with a camera look at what is left behind. Our crew works Crown Heights rowhouses, pre-war co-ops and frame houses with the same drop-cloth discipline.
Learn more →Chimney Inspection
Buying a rowhouse, converting a boiler, or just unsure what is behind the firebox? We run NFPA 211 Level 1 and Level 2 inspections with a flue camera and give you a written report you can hand to a buyer, a co-op board or an insurer.
Learn more →Creosote Removal
Glazed creosote does not brush out. When a Crown Heights flue has a shiny, tar-like coating, we use chemical treatment and mechanical chain or whip systems to break it down and remove it without damaging the clay tile.
Learn more →Dryer Vent Cleaning
Brooklyn dryers often vent through long runs to a rear wall, a roof, or a basement areaway. We clean the full duct from the dryer connection to the exterior hood and show you the airflow difference.
Learn more →Chimney Liner Installation
When the clay tile in a century-old flue has cracked, or a new gas boiler needs a correctly sized vent, a stainless steel liner gives the chimney a continuous, sealed path again. We size, insulate and terminate liners for rowhouses and pre-war buildings across Crown Heights.
Learn more →Chimney Cap Installation
Most Crown Heights chimneys lost their caps decades ago, and the water that has been running down those flues since is behind half the repairs we do. A fitted stainless or copper cap is the least expensive protection a chimney can get.

Chimney problems announce themselves in a handful of ways. Here is what each one usually means on a Crown Heights stack and where we start.
- Water stains near the fireplace or on an upper-floor ceiling: start with Chimney Leak Repair. The source is almost always the crown or the flashing, and we water-test both before touching anything.
- White efflorescence on the brick: moisture is moving through the masonry. This points to Chimney Crown Repair or Chimney Tuckpointing, and often a missing cap.
- Spalling or flaking brick faces: freeze-thaw damage from saturated brick, frequently made worse by a past repointing in hard mortar. Chimney Tuckpointing with Type N mortar and a reclaimed brick match for the worst units.
- Crumbling mortar joints you can rake out with a finger: Chimney Tuckpointing before the joints get deep enough to let the stack shift.
- A cracked chimney crown visible from the roof or a neighbor's window: Chimney Crown Repair now, before water gets into the top courses.
- Smoke backing into the room: a Chimney Sweep and Chimney Inspection first. The cause can be a blocked flue, a flue crossing from another fireplace, a closed or rusted damper, or a flue that was never sized right for the opening.
- A strong smoky or tarry smell in summer: Creosote Removal. Glazed creosote off-gasses in humid weather, and it is a fire hazard whether or not you smell it.
- A rusted damper that will not seat: a Chimney Inspection to see whether the damper can be freed or needs replacing, and to find where the water that rusted it is coming in.
- A leaning chimney stack: a Chimney Inspection from the roof the same week. Leaning stacks over Eastern Parkway sidewalks and shared parapets are a safety issue, not a cosmetic one.
- Switching from oil to gas, or a new boiler or water heater: Chimney Liner Installation. The existing flue is almost certainly the wrong size for the new appliance.
- Dryer taking two cycles to dry a load: Dryer Vent Cleaning, especially in rowhouses where the vent runs a long horizontal distance to reach an outside wall.
Frequently Asked Questions
Can you tell me which service I need over the phone?
We can usually narrow it to one or two from the symptom you describe, and we will tell you honestly if it sounds like a sweep rather than a repair. We will not quote masonry or liner work without seeing the chimney, because the price depends on height, access, how much of the stack is sound and what is connected to the flue. The inspection comes first, and the written report is what the quote is built on.
Do you do emergency chimney repairs in Crown Heights?
Yes, for the situations that cannot wait: water pouring in at the chimney during a storm, a stack that has shifted or is shedding brick, or a flue blockage that is sending smoke or fumes into the house. Call rather than email for those and we will move the schedule. Emergency work usually means stopping the water or making the stack safe first, with the permanent repair done once the weather allows mortar to cure.
Is a Level 2 inspection always necessary, or is a Level 1 enough?
A Level 1 inspection is the right fit for a chimney that is in regular use, has not changed appliances and has no known problems. A Level 2 adds a video scan of the full flue and is called for when a property is sold, when the fuel or appliance changes, after a chimney fire or after a building event like a lightning strike or earthquake. If you are buying a rowhouse here, insist on a Level 2 before closing.
What does a dryer vent have to do with a chimney company?
Same tools, same risk. A lint-packed dryer vent is a fire hazard in the same way a creosote-coated flue is, and the rotary rods and vacuums we use to clean a flue are what we use on a vent run. Rowhouse and apartment dryer vents in these buildings often run long horizontal distances to reach an exterior wall, which is exactly where lint collects. We clean them end to end and check the exterior hood.
Will you repoint a whole chimney or just the bad joints?
We repoint what is failing and leave sound joints alone, because grinding out good mortar damages the brick edges for no benefit. On most stacks we see, the failed joints are concentrated in the top courses, where weather and flue gas do the most damage. If the brick itself is spalled past repair, we cut out those units and set a reclaimed brick match so the repair blends with the original wall.
