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 Liner & Rebuild Across Kemp Mill
A chimney liner replacement or rebuild in Kemp Mill typically runs $2,800 to $7,500 depending on flue size, access, and how much of the original masonry has to come apart. Most jobs we schedule take one to three days, and we always work around the Jewish calendar: nothing starts Friday sundown, nothing runs through Saturday, and holiday dates are blocked out the same way. If you’re on University Boulevard or up near Lamberton Drive and you’ve been told you need a liner, call (240) 618-3233. Wendell will walk you through what’s actually going on before anyone touches a brick.
We’ve been inside more Kemp Mill chimneys than we can count. Most of them were built between 1955 and 1975, and most of them still have the original clay tile liners. That’s the whole conversation in this town.
Why Top Hat Chimney Is Kemp Mill’s Preferred Chimney Liner & Rebuild Company
Wendell Pike started Top Hat Chimney in 1999, and he still runs the jobs himself. When you call, a live person answers around the clock, and on a liner or rebuild job the estimate you get upfront is the number you pay. No door-price changes. Wendell puts his name on the work, and then he runs into you again at the grocery store. That changes how careful a person is.
We’ve done liner replacements and full rebuilds on split-levels off Arcola Avenue, brick colonials near Lamberton Drive, and Cape Cods tucked into the side streets south of Kemp Mill Road. The houses are different, but the finding is usually the same: cracked clay tile, deteriorating mortar, and a flue that was never sized for what’s now venting into it. Homeowners here don’t want a sales pitch. They want the camera footage and a plain-English verdict, every time, no exceptions. That’s what we deliver.
Every job comes with the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. No argument, no second invoice.
Our Chimney Liner & Rebuild Services in Kemp Mill
Stainless Steel Liner
A stainless steel liner is the permanent fix for a cracked clay tile flue, and it’s the most common job we do in Kemp Mill. The area’s 1950s and 1960s chimneys almost always have original clay tiles, and after 50 to 70 years of Montgomery County freeze-thaw cycles, those tiles crack. We install DuraFlex stainless steel liners sized to your actual appliance, not just whatever was there before. If you’ve added an EPA-certified wood-burning insert into an original 1960s firebox, the liner almost certainly needs to be upsized, and Montgomery County code now flags that mismatch.

Flexible Liner
Flexible liners make sense when the flue has offsets or when the chimney isn’t a straight vertical run. Older Kemp Mill homes sometimes have corbeled chimneys or slight bends from original construction that make a rigid pipe difficult. But we don’t recommend flexible just because it’s easier to install. The decision comes off the camera footage. If a rigid liner fits and serves the appliance better, that’s what we quote.

Liner Replacement
Replacement usually means pulling the old clay tile or degraded metal liner and installing a new stainless steel system. In Kemp Mill, we’re regularly pulling liners that cracked clean through at the smoke chamber. A Level 2 camera inspection is the only way to see that, and it’s why we never quote a liner job off a visual-only Level 1 look from the roof. Your flue doesn’t care how the fire looks. It cares how it breathes. If the liner’s compromised, creosote seeps into the mortar joints and fire risk climbs.

Partial Rebuild
A partial rebuild typically addresses the top courses of brick, the chimney crown, and the first few feet of the flue, the sections that take the most weather. Kemp Mill chimneys are aging into this work. Spalling brick and crown cracking from repeated freeze-thaw cycles leave the flue exposed to water, and homeowners often mistake the exterior damage for a simple repoint job. If water’s getting in and the liner’s compromised too, a partial rebuild is the honest scope. We show you the photos before we ask for a decision.

Trusted Brands We Service in Kemp Mill
We install and service liners and components from DuraFlex, Famco, Copperfield, and HeatShield, brands we’ve worked with for years because they hold up in Montgomery County’s climate. Because we work Kemp Mill regularly, we keep common liner diameters and components stocked locally, which shortens turnaround on a replacement. If you need a HeatShield resurfacing with a Cerfractory coating instead of a full liner tear-out, that’s a conversation worth having once the camera tells us what we’re working with.
Common Chimney Liner & Rebuild Problems We See in Kemp Mill Homes
- Cracked clay tile liners from the original 1950s-1970s construction. Most Kemp Mill chimneys still have their first flue liner. After decades of heating and cooling, the tiles crack. A Level 1 inspection from the roof won’t catch it, and creosote then seeps into the mortar joints, quietly raising the fire risk.
- EPA wood-burning inserts installed into original 1960s fireboxes without a liner upgrade. The older undersized clay tile flues can’t handle the higher flue gas temperatures from a modern insert. Montgomery County code now flags this. We see it on a large share of calls.
- Spalling brick and crown cracking that hides a liner problem. Freeze-thaw cycles in Montgomery County repeatedly push water into the masonry, and the crown fails first. Homeowners see the cosmetic brick damage and think it’s a repoint job. It’s often a liner and crown rebuild.
- Water-damaged flues that went years without an inspection. Chimneys break in the off-season too. A liner with water stains, rust, or mortar washout is usually the result of a crown failure that started several winters ago. Once a year, burn or no burn.
Pricing for Chimney Liner & Rebuild in Kemp Mill, MD
A stainless steel liner replacement in Kemp Mill typically runs $2,800 to $4,500 for a single-flue, straight-run chimney, depending on height and access. Flexible liners in the same homes run close to that range, $3,000 to $4,800 when the flue has offsets. A partial rebuild that includes relining the top section and rebuilding the crown generally lands between $3,500 and $6,500. A full chimney rebuild from the roofline up in Kemp Mill starts around $6,000 and can reach $12,000 or more if the firebox and smoke chamber are involved.
What actually drives the price is access and scope: how tall the chimney is, whether scaffolding is needed, and what the camera shows once we open things up. You’ll get a firm number before any work begins, and we offer $40 off any repair over $200 and a free second opinion on any competing written estimate. Call (240) 618-3233 and Wendell will give you the real number.
The Kemp Mill Scheduling Reality
Kemp Mill is one of the most concentrated Orthodox Jewish communities in the DC metro area, and that shapes how chimney work gets scheduled. No work runs from Friday sundown through Saturday night. None. Roughly 30-plus holiday days a year are blocked out the same way, and our Kemp Mill schedule bends around that calendar entirely. Weekday-only scheduling is the default here, unlike Silver Spring or Wheaton where Saturday work is routine.
What that means in practice: there’s a distinct pre-Passover spring surge. Homeowners want the chimney cleaned, the liner inspected, and any rebuild work finished before the holiday begins. If you’re planning a liner replacement or rebuild, call in late winter. The calendar fills up fast once February turns to March.
We had a job on Lamberton Drive where a homeowner complained about a smoky draft every time they lit the firebox. The Level 2 camera caught it: a 1960s clay tile liner cracked clean through at the smoke chamber. We installed a DuraFlex stainless steel liner, parged the smoke chamber, and rebuilt a chimney crown that had been spalling from years of Montgomery County freeze-thaw cycles. Then we re-scheduled the final day of the job to avoid Shabbat. Our Kemp Mill schedule always bends around the calendar. That’s just how it works here.

FAQs - Chimney Liner & Rebuild in Kemp Mill
Because the original clay tile liner in a 1950s split-level is now 65 to 75 years old, and Montgomery County’s freeze-thaw cycles have been working on it every winter. Clay tile cracks from thermal stress, and once it cracks, creosote and flue gas reach the surrounding mortar and masonry. A stainless steel liner, sized correctly, is the permanent fix. If you’ve added a wood-burning insert, the original liner is also likely undersized for the hotter flue gases. Call (240) 618-3233 and we’ll show you the camera footage before recommending anything.
Yes. It’s not an accommodation we occasionally make; it’s how we schedule Kemp Mill jobs as a rule. No work from Friday sundown through Saturday night, and holiday dates blocked out. A full chimney rebuild takes multiple days, so we’ll sequence the work across weekdays and plan the calendar with you before the first brick comes off. If you’re planning a pre-Passover rebuild, call early in the year because spring slots fill quickly, and the calendar doesn’t bend for late bookings. Reach us at (240) 618-3233.
You know by running a Level 2 camera inspection, not by looking down from the roof. In a 1960s brick colonial in Kemp Mill, we’re typically looking for hairline cracks, spalled tile faces, gaps at the mortar joints, or damage at the smoke chamber. Small surface cracks can sometimes be addressed with a resurfacing product like HeatShield’s Cerfractory coating. A crack that runs through the tile or a liner that’s separating means replacement. We’ll show you the footage and give you a plain-English verdict, every time, no exceptions. Call (240) 618-3233 for a free estimate.
You create a mismatch the original clay tile flue was never designed to handle. EPA-certified wood-burning inserts burn hotter and more efficiently, which pushes up flue gas temperatures. An undersized 1960s clay tile liner can’t safely vent that, and Montgomery County code now flags the installation. The fix is a correctly sized stainless steel liner, and it’s one of the most common jobs we do in Kemp Mill. If you’ve already had an insert installed, a camera inspection will show whether the liner is right. Call (240) 618-3233 to get one scheduled.
Because Montgomery County winters repeatedly cross the 32-degree threshold, and the crown, the concrete slab at the top of the chimney, takes the brunt of every freeze-thaw cycle. Water gets into small cracks, freezes, expands, and opens the crack wider. A 1970s Cape Cod in Kemp Mill has now been through roughly 50 winters of that. The fix is a proper crown rebuild with the right concrete mix and an overhang that sheds water away from the flue, but only after checking what’s underneath. If the liner’s damaged from all that water entry, the crown job alone won’t solve the real problem. Call (240) 618-3233 for an inspection and a quote that shows you exactly what’s needed.
