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.
Fast, Reliable Chimney Repair Across Glendale
Chimney repair in Glendale, NY usually means one of three jobs on these 1920s and 1930s brick row houses: repointing crumbling mortar joints, rebuilding a spalled crown above the roofline, or relining a century-old clay tile flue that was sized for coal and never meant to handle a modern gas boiler. Most repairs we quote in Glendale run between $400 and $2,800 depending on what the camera shows us. Wendell Pike and his crew have been inside more Glendale chimneys than we can count, and we will tell you straight if the work can wait. Call (929) 822-6306 and a live person answers, day or night.
Why Top Hat Chimney Is Glendale’s Preferred Chimney Repair Company
We are not a franchise that rotated into Queens last spring. Top Hat Chimney has been owner-operated since 1999, and Wendell puts his name, his license number, and his published address on every job. Ask anyone on your street. Glendale homeowners call us because the sweep who shows up at the door is background-checked, in uniform, and gives you a real arrival window. If the window slips, Wendell or his crew will call you before you have to call us.
What that means in Glendale specifically: we know the interior ceiling chases on those attached brick two-families off Myrtle Avenue. We know the roof access on 71st Street and 73rd Place where the stacks rise above flat or low-slope rooflines and take the full brunt of Queens freeze-thaw cycling every winter. We have opened cleanout doors and found coal chambers the homeowner never knew existed. That is the kind of local knowledge that changes a quote from a guess into a real number. Every repair we finish is backed by the 90-Day Done Right Promise in writing. If it is not right, one call brings us back, no charge.
Our Chimney Repair Services in Glendale
Here is what we actually do most weeks in Glendale. Chimney Repair covers everything from a missing brick to a full stack rebuild, but these four jobs make up the bulk of the calls.
Mortar Repointing in Glendale
Those pre-war brick row houses on 69th Lane and 75th Street have lime-based mortar that was never designed to last a hundred years. Freeze-thaw is the enemy: water gets into micro-cracks in fall, freezes and expands all winter, and by spring the joints look like sand running down the brick face. Repointing in Glendale typically runs $900 to $2,400 depending on how much of the stack is deteriorated. We cut out the failed mortar and pack in fresh, with a color match so the repair does not look like a patch job.

Spalling Brick Repair in Glendale
Spalling is what happens when brick faces pop off, usually because water got trapped inside the brick and froze. In Glendale it shows up first on the north and east faces of exposed chimneys, the ones that never dry out after a nor’easter. A few spalled bricks can be cut out and replaced. A stack with spalling from the roof line up usually needs partial rebuilding. Figure $700 to $1,800 for spot replacement, and $2,500 to $5,000 if we are tearing down and rebuilding the top several courses. We will show you the difference on camera before you spend a dollar.

Chimney Waterproofing in Glendale
Waterproofing is the most under-sold chimney repair there is, because it does not fix anything you can see. What it does is stop the slow soak that ruins everything else. We apply a vapor-permeable water repellent, often Gelco or ChimneySaver, to the masonry above the roofline. It lets the chimney breathe while shedding rain and snow. On a Glendale row house, full waterproofing runs $350 to $700 for a typical single stack. If we are already repointing, it is a small add and the smart move.

Flashing Repair in Glendale
Flashing is the metal at the roof line where the chimney meets the shingles or roll roofing. In Glendale, we see flashing failures constantly on those flat and low-slope rooflines. A pinhole or a lifted seam lets water run down the outside of the flue for years without you seeing a damp spot inside until it is too late. Flashing repair or replacement runs $450 to $1,200 in Glendale depending on whether it is a simple re-seal or a full tear-out and re-lead. We use Famco flashing and counter-flashing for a fit that holds up to Queens weather.

Trusted Brands We Service in Glendale
When a liner goes, we do not cut corners on what goes back in. We install and service DuraFlex stainless steel liners, HeatShield cerfractory sealant systems, and Gelco waterproofing products. For Glendale homeowners, that means we know the exact sizing for the old coal-era flues on these blocks, and we carry the common parts in the truck. A stock liner for a typical Glendale boiler flue is usually installed same-week once the NYC DOB permit clears. No ordering a part from a warehouse and hoping it shows up.
Common Chimney Repair Problems We See in Glendale Homes
There is a pattern to Glendale. Same housing stock, same era, same flue design. Here is what we see again and again:
- Coal-to-gas liner mismatch. An 80,000-BTU gas boiler venting into a flue built for a coal furnace that put out far more combustion gas. The oversized flue never gets hot enough to push the water vapor out, so acidic condensate eats the clay tile from the inside. The fix is a properly sized stainless liner, pulled under permit.
- Shared flue cross-contamination. In attached homes on blocks like 68th Avenue and Cooper Avenue, two families often share one interior chimney stack. A crack in one side’s liner can push combustion gas into the other side’s second-floor bedroom. This is not a Nassau County problem. It is a Glendale problem.
- Crown and mortar failure from freeze-thaw. Exposed stacks above flat rooflines take the full winter cycle. Cracked crowns let water straight into the flue, and the liner fails from the outside in. We document this at every cleaning.
- Backdrafting after a cleaning. A chimney gets cleaned, and suddenly the boiler or water heater starts backdrafting. What actually happened: the cleaning removed the last of the blockage that was masking an undersized liner and a draft problem that was already there. We diagnose it with a camera and a draft test, and the fix is usually a liner, not another cleaning.
Key Takeaways for Glendale Homeowners
- Re-pointing small mortar failures early stops them becoming a $4,000 rebuild.
- Your flue doesn’t care how the fire looks. It cares how it breathes.
- A camera inspection with written photo report is included on every estimate. No exceptions.
- NYC DOB permits are required for liner replacement in Glendale. We pull them and coordinate inspections.
- Once a year, burn or no burn. Chimneys break in the off-season too.

FAQs - Chimney Repair in Glendale
We camera-inspect both sides of the stack from each cleanout, document the damage, and then sit both families down with the footage and a plain-English verdict. If one liner is cracked and the other is still sound, we can sometimes reline just one side by pulling a smaller-diameter stainless liner through the existing flue passage, but in most pre-war Glendale stacks both clay liners are the same age with the same condensate damage. Usually the smart move is relining both flues under a single NYC DOB permit, splitting the cost with the neighbor, and never having the cross-contamination conversation again. Call (929) 822-6306 and we will walk you through the sequence before you talk to the neighbor.
Your boiler is most likely venting into an oversized coal-era flue that was never relined when the house switched to gas. The flue is too big and too cold to maintain draft, especially after a cleaning removes the last bit of blockage that was accidentally helping. We confirm it with a draft test and a Level 2 camera inspection, then fix it with a correctly sized stainless liner. This is the single most common repair we do in Glendale. Call (929) 822-6306 and we will tell you from the inspection what is actually going on.
Yes, and in Glendale it is happening right now on dozens of roofs. Water enters a hairline crack in the crown, soaks into the mortar joints and brick, freezes and expands through the winter, and the liner erodes from the outside. You will not see a damp spot on the ceiling until the damage has been underway for years. That is why we flag crown and mortar condition at every cleaning on these exposed Glendale stacks. The fix is usually a crown repair or waterproofing, $350 to $1,200, before it becomes a $3,000 liner replacement.
Every two to three years, plus whenever you change the appliance connected to the flue or after any major storm that blew water sideways onto the stack. A stainless liner is not a set-it-and-forget-it situation. We still want eyes on the crown, the flashing, and the top plate to catch the next failure before it starts. Call (929) 822-6306 and we will schedule a camera inspection with a written photo report. The estimate is free.
Because Glendale is in New York City, and the Department of Buildings treats liner replacement as an alteration to a fire safety system. Nassau County has its own rules, but they are not the same. We pull the permit, we handle the DOB inspection, and we do the paperwork. You never have to stand at a DOB window. The permit adds about $300 to $600 to the total depending on scope, and it is non-negotiable if you want the job done legally and your homeowners insurance intact. Call (929) 822-6306 and we will give you the real all-in number, permit included, before you commit.
