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.

AfterChimney Cleaning in Rockville, MD
Chimney cap and crown work in Rockville usually starts with a cracked or spalled crown cap and ends with a written quote in the $350-$850 range, depending on whether we’re sealing, rebuilding, or replacing. Call (240) 220-9412 for a free estimate. Rockville’s mid-century housing stock, especially the post-WWII Cape Cods and colonials in Twinbrook and Lincoln Park, makes this a different job than in newer Montgomery County subdivisions – 70-year-old mortar and clay tile don’t forgive freeze-thaw cycles at 450-500 feet of elevation the way a 1990s prefab insert does.
Why Rockville Homes Are Different
Rockville sits on the Piedmont Plateau, roughly 450-500 feet above sea level. That means colder winters and more freeze-thaw cycles than DC or Bethesda see, and those cycles are relentless on masonry. The Twinbrook, Jefferson Park, and Lincoln Park neighborhoods were built fast in the late 1940s through the 1970s – brick-and-frame colonials and Cape Cods with original single-flue chimneys and clay tile liners. Those liners are now 70-80 years old. Humid summers promote biological growth inside unused flues, and icy winters attack mortar joints. So a routine cleaning in Rockville frequently surfaces a liner or crown problem that’s been developing for decades, not months.
We see it in Twinbrook constantly: the original 1950s clay tile liners shifted when the homes settled, and the joints were never re-mortared. When a sweep dislodges loose tile fragments, the real issue surfaces – and that’s why we treat every Rockville cleaning as a likely precursor to a camera inspection and a liner or crown repair.
Our Main Rockville Services
These are the three services Rockville homeowners call us about most, each with its own page and its own Rockville-specific detail.
Chimney Cleaning & Sweep in Rockville
Chimney cleaning in Rockville means dealing with creosote from wood fires in mid-century masonry chimneys and gasket-seal and creosote issues in 1980s-90s prefab inserts. We always pair the sweep with a camera-scan inspection, because the freeze-thaw damage we find in Twinbrook and Lincoln Park often changes what the homeowner needs next. Full details are on the Chimney Cleaning & Sweep in Rockville page.
Chimney Repair in Rockville
Rockville’s older homes settle, and the chimneys settle with them. We repair cracked crowns, spalling brick, and failed mortar joints before water gets behind the veneer and makes a small job a big one. The repair estimate always comes as a written price with camera evidence attached. See the Chimney Repair in Rockville page for specifics.
Fireplace Services in Rockville
From drafting complaints to gas insert inspections, fireplace service in Rockville usually begins with figuring out whether the firebox, the flue, or both are at fault. We inspect the smoke chamber and damper assembly and document everything with photos before quoting anything. The Fireplace Services in Rockville page covers what we do and what it costs.

BeforeAfterChimney Cap & Crown in Rockville
Chimney cap and crown work in Rockville is often the first repair a Twinbrook or Lincoln Park homeowner needs, because the original 1950s crown caps shed mortar over decades of Piedmont freeze-thaw cycles until water reaches the clay tile liner and starts the spalling process. A camera-scan inspection on every visit catches this before it becomes a rebuild – that’s the whole point of the Chimney Cap & Crown service. On Rockville’s mid-century colonials, we’re typically replacing a rusted or missing cap and rebuilding the crown in the same visit.
Cap Installation
Signs you need it
Missing cap, corroded cap, or wildlife entry through an open flue.
What it costs in Rockville
$350-$650 depending on flue size and cap material; Olympia Chimney and Famco caps are commonly stocked for this area.
How we do it
We measure the flue, install the matched cap onto a sound mortar base, and photograph everything before and after.
Crown Repair
Signs you need it
Crumbling crown mortar, standing water on the crown, or vertical cracks visible from the ground.
What it costs in Rockville
$450-$850 for full crown rebuild; smaller crack filling runs $150-$300.
How we do it
We remove loose mortar, clean the crown surface, and re-form the slope so water drains away from the flue.
What Chimney Cap & Crown Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Cap installation | $350-$650 |
| Crown crack fill | $150-$300 |
| Full crown rebuild | $450-$850 |
Can you fix a cracked crown without replacing the whole chimney?
Yes. We re-form and seal the existing crown whenever the underlying masonry is sound. Camera photos show you exactly what was done.
Does a missing cap really cause liner damage?
Yes. Water entry through an open flue accelerates clay tile deterioration and rusts metal components. Caps are the cheapest prevention we sell.
Chimney Liner & Rebuild in Rockville
Liner replacement and chimney rebuild work in Rockville usually starts in Twinbrook, where 70-year-old clay tile liners have shifted at the joints and cleaning dislodges loose tile fragments. The freeze-thaw cycles at this elevation crack those tiles faster than in lower-lying areas. That’s what the Chimney Liner & Rebuild service addresses – a documented liner condition assessment, then a written scope before any rebuild work begins.
Stainless Steel Liner
Signs you need it
Cracked clay tile sections or flue gases leaking into the chimney chase during a camera inspection.
What it costs in Rockville
$1,800-$3,500 installed, including the liner, insulation, and top plate.
How we do it
We size the liner to the appliance and flue, drop it in from the top, insulate the annular space, and re-attach the cap and crown.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, failed mortar joints, or a leaning top section.
What it costs in Rockville
$1,200-$4,000 depending on how many courses of brick need to be re-laid.
How we do it
We dismantle to sound brick, re-lay with matched mortar, and re-form the crown before installing a new cap.
What Chimney Liner & Rebuild Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Stainless steel liner | $1,800-$3,500 |
| Partial rebuild (above roof) | $1,200-$4,000 |
| Full chimney rebuild | $8,000-$18,000 |
Do I really need a new liner, or can the old clay tile be patched?
Clay tile liners cannot be reliably patched. If camera inspection shows cracked or shifted sections, replacement is the only safe fix.
Can I keep using my fireplace while the liner is cracked?
No. Cracked liners let flue gases and heat reach combustible framing. Stop using the fireplace and call us for a camera inspection.
