I’m Tomer, and I run The Chimney Experts. When you book chimney repair in Bethel Park, PA, it is me or the guys I trained getting on your roof, and I stand behind the work either way. Bethel Park sits in the South Hills, and most of what I open up here is a masonry fireplace built decades ago, with a clay tile flue and a rough brick smoke chamber above the firebox. Those get old in a predictable way, and the fix is usually a liner, a proper smoke chamber parge, and a damper that actually seals. If your fireplace smells, smokes back into the room, or you can feel cold air pouring down it in January, call me and I’ll get up there and tell you straight what it needs.

A Fireplace Relining Job We Did in Bethel Park
The homeowner called us because the fireplace was smoking back into the living room whenever they got a fire going, and the room stayed drafty even with the fire out. They had been burning in it anyway, which is how most people find me.
What my crew found when they got into it: the clay tile liner in the fireplace flue had cracked and the joints between tiles had opened up, so the flue was no longer one sealed path from the firebox to the top. Above the firebox, the smoke chamber was raw stepped brick. That is how these were built, with the courses corbeled inward to narrow the throat, and every one of those steps is a shelf that grabs smoke, slows the draft, and collects creosote. There was no parge coat on it at all. Up top, the old throat damper down at the firebox was rusted and warped and no longer closing on anything, which is why the room never warmed up. That chimney was an open hole in the roof year round.
So the fix was three pieces, and they work together. First we ran a new stainless liner down the full length of the fireplace flue and sealed it at the top, which gives the smoke one continuous, correctly sized path out. Second we parged the smoke chamber, troweling the coat over the stepped brick until the inside was smooth and the corbeling was sealed. That is what code asks for, and it is also what makes the chimney pull instead of stall. Third we set a top-sealing damper at the crown, the kind with a silicone gasket and a cable that runs down to a handle in the firebox, so the homeowner closes it from inside when the fireplace is not in use.
How it performs now: the draft is right, so the smoke goes up instead of into the room. The flue is sealed end to end. And when they close that top damper, the whole chimney is shut off at the roof, not at a rusted plate above the firebox, so the heat they paid for stays in the house.
Why Bethel Park Fireplaces End Up Needing This
Bethel Park filled in as a South Hills suburb, so the housing stock runs heavily to brick ranches, split-levels, and two-story colonials from the middle of the last century, with a scattering of older homes from before the borough grew. Almost all of them were built with a real masonry fireplace and a clay tile flue, back when that was standard and nobody thought about what it would look like in fifty or sixty years.
Here is what age does to that setup. Clay tile cracks, and the mortar joints between the tiles wash out, so the flue stops being sealed. The smoke chamber was corbeled brick from day one, and if it was ever parged, that coat has usually fallen off by now. The original throat damper is a thin cast plate sitting in a masonry throat, and after decades of heat and rust it warps and quits sealing. None of that means the chimney is junk. It means it needs the inside brought back up to standard, which is exactly the work I described above.
The Chimney Repairs I Do in Bethel Park
Chimney repair here is usually inside work, not brick and mortar on the outside, though I do plenty of both.
Fireplace and Flue Relining
When the clay tile has cracked or the joints have opened, I run a stainless liner sized to the fireplace and seal it top and bottom so the flue is one continuous path again. Same goes for a furnace or water heater flue, which is its own situation. I go through that on my chimney relining page, and if the flue in question is serving gas heat, see gas furnace liners.
Smoke Chamber Parging
The smoke chamber is the space between the top of your firebox and the bottom of the flue, and on older fireplaces it is bare stepped brick. I parge it so the inside is smooth and sealed. That gets it to code, it stops smoke and creosote from catching on every ledge, and it keeps heat off the surrounding masonry. It is one of the biggest improvements you can make to a fireplace that has never drafted right.
Damper Installation
If the throat damper is rusted open or missing, I would rather put a top-sealing damper at the crown than fight the old one. It seals with a gasket at the top of the flue, it doubles as a rain and animal cover while it is closed, and you work it with a cable from inside the firebox. On chimneys where a top damper is not the right call, a chimney cap still keeps rain and animals out. I wrote up why chimney caps matter if you want the reasoning.
Crown, Masonry, and Flashing Work
Outside, I rebuild and seal cracked crowns, repoint washed-out joints, replace spalled brick, and reseal flashing where the chimney passes through the roof. Water coming in the top is what wrecks the inside, so this often runs alongside a liner job. There is a step-by-step crown rebuild before and after on my blog, and the full list is on my Pittsburgh chimney repair page.
Sweeps and Inspections
Before I quote any of the above I sweep and inspect the chimney, because I am not guessing at what is behind the brick. You get told what I found and what it actually needs, nothing padded on.
What a Visit Looks Like
You call, I come out, and I get on the roof and into the firebox instead of judging the chimney from the driveway. I check the liner down the flue, the smoke chamber above the firebox, the damper, the crown, and the flashing at the roofline. Then I walk you through what I found and give you a written estimate for only the work the chimney needs. I would rather you be home for it so I can show you, and the estimate is free either way.
Chimney Repair Across Bethel Park and the South Hills
Bethel Park is right in the middle of the South Hills territory I cover. Along with Bethel Park I work Upper St. Clair, Whitehall, Pleasant Hills, Castle Shannon, South Park, and Peters Township, plus Mt. Lebanon just up the road, where the housing runs older and the repairs lean more toward crowns and masonry. If your fireplace has been smoking or you have not had the flue looked at in years, call me before you burn in it again this winter.
