OVERVIEW
The Small Part That Protects Your Home and Your Heating Bill
Your fireplace damper sits at the top of the firebox and seals your chimney when the fireplace is not in use. When it works, it stops heated and cooled air from escaping up the flue, and it blocks cold drafts, rain, and smoke from coming back down. When it fails, you feel it in a colder room and a higher heating bill.
We handle chimney damper repair for stuck, rusted, and leaky dampers, and we take on chimney damper installation when a repair no longer makes sense. Every damper is measured and cut to the exact size of your flue so it closes tight, seals cleanly, and holds up season after season, and the parts we install are backed by a lifetime warranty. Whether you need a quick fix or a full damper replacement, you get a fireplace that vents safely when you light a fire and stays sealed when you do not.

WHEN YOU NEED IT
Signs Your Fireplace Damper Needs Repair or Replacement
A damper problem is easy to overlook until the cold weather arrives. Here are the signs that tell homeowners it is time for chimney damper repair or a full damper replacement.
-
A throat damper that will not open or close
If the handle sticks or the plate no longer moves freely, the damper cannot seal or vent properly, and smoke can back up into the room.
-
A rusted or stuck damper
Moisture in the flue corrodes the metal over time. A rusted plate warps, jams, and stops sealing.
-
Cold air pouring in when the fireplace is off
A steady chill near the hearth means the damper is no longer closing tight against the flue.
-
Higher heating bills from a leaky damper
A worn or ill fitting fireplace damper lets your heated and cooled air slip up the chimney all year, and you pay for it every month.
-
A whistling or rattling sound at the hearth
Air forcing past a warped or loose damper plate often makes noise, a clear hint the seal has failed.
-
Water, soot, or animal debris in the firebox
A damper that no longer seals lets rain, nesting animals, and outside grit into your chimney and home.
-
A missing or broken damper
With no working damper at all, your home is open to weather, animals, and drafts. This calls for a new fireplace damper installation.

What Our Clients Say
Mike S.
Chimney Professionals did a terrific job cleaning my two wood burning fireplaces in a Manhattan brownstone. They came within one day. Their equipment is state of the art, and it was all done in less than 30 minutes. Everything kept spotless. The price was right too.

M. J.
Not only did they answer right away, they had Rod at my door first thing Monday morning and sourced a hard to find part same day when others could not. They beat every other quote I got and had our system back up and running in under an hour.

Bruce S.
The chimney in my 115 year old brick rowhouse had a badly deteriorated terra cotta lining. Michael gave me a fair price, was punctual, and while spending more time than he expected, stuck to the original price. Kudos to Michael for getting a tricky job done.

Jim S.
Mike and his team are phenomenal. Very quick to respond and schedule and then more importantly, absolute professionals. Deep cleaned the chimney and made sure they cleaned any residual dust around the area.

Our building needed three new liners for each apartment. They did a great job with the removal and new installation. Mike was very easy to work with, and very responsive with any follow ups.

We asked them to inspect our roof and chimney before an upcoming home inspection. They explained every detail clearly, helped us understand what needed fixing, and even assisted with budgeting.

They were able to come out next day and fix our gas fireplace issue. They listened to all of our concerns and addressed any questions we had while thoroughly explaining the work that needed to be done. The price was fair and upfront.

Mike set up an appointment for the next day to clean our dryer vent. He maintained good communication the whole time. The technician who arrived was professional and did a thorough job. The price was reasonable too.

FAQ
Damper Questions Homeowners Ask
If the damper is only sticking or slightly out of alignment, a repair often solves it. If it is heavily rusted, warped, or missing, a damper replacement is the safer and more lasting choice. We tell you honestly which one your fireplace needs during the free estimate.
Yes. A damper that seals tight stops your heated and cooled air from escaping up the flue, which reduces the energy you lose all year. A top sealing damper seals even more completely than a traditional throat damper.
A throat damper sits just above the firebox and can leak as it ages. A top sealing damper closes at the very top of the chimney with a tight gasket, giving you a better seal against drafts, rain, and animals.
It depends on whether you need a repair or a replacement, the type of damper, the size and shape of your flue, the condition of the surrounding chimney, and access to your home. During your free estimate we walk through each of these and give you a written price before any work begins.
Many damper repairs and installations are finished in a single visit. The exact time depends on the type of damper, the condition of your chimney, and access to the roof, all of which we confirm during your free estimate.
It is not a good idea. A damper that will not open can trap smoke in your home, and one that will not close lets drafts, water, and animals in. We recommend chimney damper repair or replacement before your next fire.
Have your damper inspected once a year, ideally before the heating season, so a small issue like early rust or a loose handle is caught before it becomes a bigger repair.
We offer free same day estimates and same day appointments in most cases, plus 24/7 emergency service if smoke is backing up or a draft problem cannot wait.
No. We protect your floors and furniture, work cleanly, and leave the area tidy, then give you a certificate confirming the job is complete.
