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.

AfterFast, Reliable Chimney Liner & Rebuild Across Robinwood
Chimney liner replacement or a partial rebuild in Robinwood typically costs $2,800-$6,500 depending on the flue size, liner material, and how much masonry needs reconstruction. Most jobs wrap up in one to three days on site. That’s the honest range we quote over the phone, and the number Wendell puts on your invoice before he pulls a single tool off the truck.
If you live in Robinwood, you already know the two-flue chimney setup in your ranch or split-level isn’t something a flatlander sweep sees every day. We do. Call (240) 534-1247 and Wendell or one of his crew will walk you through exactly what your chimney needs, and just as importantly, what it doesn’t.
Why Robinwood Homeowners Call Top Hat Chimney First
Wendell Pike started Top Hat Chimney in 1999 and has spent nearly three decades inside Washington County chimneys. He answers his own phone half the time, and when he comes to Robinwood, he already knows what he’s likely to find before he steps on your roof. The two-flue masonry chimneys around Robinwood Drive, Oak Ridge, and the quieter lanes off Mount Aetna Road aren’t a surprise to him. They’re the job.
Robinwood homeowners don’t like surprises either. We get that. Every job gets a Chimney Liner & Rebuild team that shows up in uniform, with a real arrival window, and a published license number that belongs to a real person you’ll run into at the hardware store on Saturday. The 90-Day Done Right Promise is stamped on every invoice. If something isn’t right, one call brings Wendell back. No arguments, no runaround.
A live person answers our phone 24 hours a day. Not a voicemail tree. If your furnace flue is backdrafting into the house on a cold valley morning, you get a human, not a callback.
Our Chimney Liner & Rebuild Services in Robinwood
Stainless Steel Liner
When a Robinwood homeowner asks what liner we’d put in our own mother’s chimney, we say stainless steel. Usually DuraFlex or Gelco, sized precisely for the appliance. Stainless handles the condensation that comes with gas furnace flues in our cold valley climate without rusting or flaking. Robinwood’s housing stock is full of undersized original clay liners that were never touched during oil-to-gas conversions, and a properly sized stainless liner fixes the draft, the condensation, and the carbon monoxide risk in one pass.
Flexible Liner
Flexible liners make sense when the flue has offsets or the original masonry isn’t a straight shot from firebox to crown. A lot of Robinwood’s 1960s and 1970s chimneys have slight offsets baked into the construction. A flexible stainless liner snakes through cleanly without tearing out the chimney chase or cutting into finished walls. We use Olympia Chimney and Famco components whenever the existing tile has survived but the path isn’t straight.
Liner Replacement
The most common replacement we do in Robinwood is pulling a spalled, cracked clay liner out of a gas furnace flue and dropping a properly sized stainless liner in its place. It’s not a patch job. It’s the fix that stops flue gases from migrating into the wall cavity or the living space. We camera every liner before and after, so you see what the old liner looked like and what the new one does. If the damage is limited to a middle section, we’ll tell you plainly whether a repair makes sense or whether replacement is the only honest answer.
Partial Rebuild
A partial rebuild usually means we’re tearing down and reconstructing the top courses of the chimney: the crown, the upper flue tiles, maybe the shoulders. Around Robinwood, freeze-thaw cycling beats up exposed masonry hard. A chimney that looks fine from the ground can have a crumbled crown and a flue tile that’s skating around loose under the cap. We can rebuild from the roofline up without touching the fireplace inside, which keeps the job to a day or two in most Robinwood homes.

Trusted Brands We Service in Robinwood
We stock and install DuraFlex, HeatShield, and Gelco components, along with Olympia Chimney and Famco caps, terminations, and connectors. Copperfield dampers are a go-to for older Robinwood fireplaces that never had a top-sealing damper. Because we carry local parts inventory for Washington County jobs, a liner replacement in Robinwood doesn’t sit waiting on a truck from Ohio. If we need a 6-inch stainless liner kit for a 1972 split-level on Meadowbrook, we likely have it on the shelf that afternoon.
Common Chimney Liner & Rebuild Problems We See in Robinwood Homes
- Retained original clay liners after oil-to-gas conversion. Washington County homes that switched from oil to natural gas decades ago often kept the original clay flue liner. Low-temperature gas exhaust condenses inside that oversized clay, and the liner starts spalling from the inside out. It’s a code issue and a carbon monoxide risk that a camera inspection will catch in ten minutes.
- Deteriorated mortar joints between the two flues. That fireplace-and-furnace side-by-side configuration is the norm here, not the exception. When the interior mortar between flues crumbles, flue gases from the furnace pass into the fireplace flue, then back into the living room. We find this all over the Robinwood area, especially in ranches built between 1965 and 1985.
- Valley wind reversals exposing liner cracks. Washington County’s ridge-and-valley topography creates localized wind reversals and temperature inversions. On a windy day near the base of South Mountain, your flue can pull smoke backward. If the liner has a hairline crack, that’s when you smell it. A liner replacement fixes the symptom only if the termination is also corrected, and we check both.
- Undersized flues in multi-appliance masonry chimneys. Robinwood’s ranch and split-level homes often run a fireplace, a furnace, and a water heater through one masonry structure. If the liner was sized for a wood stove or an old oil burner and now carries a gas appliance, the draft suffers. A correctly sized stainless liner restores the siphon the chimney needs to breathe.

FAQs - Chimney Liner & Rebuild in Robinwood
The most common liner problem we find in Robinwood’s 1960s ranch homes is a spalled original clay liner that was never properly relined after an oil-to-gas furnace conversion. Condensation eats the clay from the inside, leaving flakes and cracks that let flue gases leak into the house. The fix is a stainless steel liner sized for the gas appliance. If you haven’t had a camera inspection, call (240) 534-1247 and we’ll schedule one before the next cold snap.
Even an occasional fireplace shares its masonry chimney with the furnace flue. If the liner between those two flues has failed, you can have carbon monoxide entering the living space even when the fireplace is cold. Robinwood’s valley climate also means your chimney is under freeze-thaw stress all winter whether you burn or not. Once a year, burn or no burn. A Level 2 inspection with camera costs less than the deductible on a chimney fire claim. Book yours by calling (240) 534-1247.
In older Robinwood homes with a side-by-side two-flue chimney, we have to verify the condition of the masonry wythe between the flues. If that shared wall is sound, we can reline one flue without disturbing the other. If the mortar between flues has crumbled, we rebuild that section before dropping the new liner. It adds a day and some cost, but it’s the only way to keep furnace exhaust out of your fireplace flue. We’ll show you the camera footage either way.
Yes, a partial rebuild can fix a spalling clay liner when the damage is concentrated in the upper flue tiles and the top of the chimney. We tear down the crown and the bad courses, pull the damaged liner sections, and either replace just those tiles or sleeve the entire flue with a stainless liner. If the spalling extends deep into the lower chimney, a full liner replacement is the honest call. We’ll tell you which one you actually need, with photographs, before any work begins.
For gas furnace flues in Robinwood, we install DuraFlex stainless steel liners most often. They handle the condensation from low-temperature gas exhaust without corroding, and they handle the acidic byproducts of high-efficiency gas appliances better than aluminum or clay. Gelco is another solid product when the flue has a straight, clean run. We size the liner to the appliance, not to the old flue, which is where a lot of replacement work goes wrong. Call (240) 534-1247 for a free estimate and we’ll tell you what your chimney needs.
Chimney Safety in Robinwood’s Valley Climate
Robinwood sits in Washington County’s Appalachian ridge-and-valley corridor, which gives your chimney a different set of challenges than a Baltimore or Bethesda home would face. January averages run colder. Snow load is higher. The valley walls create wind reversals and temperature inversions that flip your flue draft around on certain days. Homes on the slopes of South Mountain or in the low spots along Beaver Creek feel this more than others.
The two-flue masonry chimney that’s so common in Robinwood’s 1950s through 1980s housing stock means every liner inspection actually matters twice. A liner failure in the furnace flue isn’t just a draft problem. It’s a carbon monoxide pathway into your living space. That’s why we recommend annual Level 2 inspections with camera documentation for any Robinwood home with a shared masonry chimney, especially after a furnace conversion or a new gas appliance install.
The Real Reason We Camera Every Liner We Recommend
If you’ve been burned before by a big national outfit that quoted one thing on the phone and another at the door, you’re exactly why we do things differently. Wendell has owned this company since 1999 and he puts his name on every job in Robinwood. That means we don’t tell you a liner is “shot” without handing you the camera footage to prove it.
A few seasons back, we inspected a 1970s split-level near Robinwood Drive where the homeowners had noticed backdrafting on windy valley days. The camera found the original clay flue liner for the gas furnace had spalled badly after decades of thermal cycling, and the flue was oversized for the gas appliance. We installed a DuraFlex stainless steel liner sized for the furnace. The draft problems stopped. Those customers get an annual Level 2 inspection now, and the cameras catch first-degree creosote in the fireplace flue before it turns into a tar glaze. That’s how it should work.
