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 runs $185 to $640, while liner and rebuild work typically lands between $1,400 and $7,250 depending on what the camera finds. Rockville’s housing stock makes this different from most Maryland markets: thousands of 1950s-era chimneys in Twinbrook were built without clay tile liners or with terra cotta that cracked decades ago. Call (240) 621-1264 and we’ll put a camera down the flue before recommending anything.
Why Rockville Homes Are Different
Rockville doesn’t have one housing era; it has three, and a sweep has to know all of them. Twinbrook and parts of Hungerford carry the original 1950s masonry chimneys built for federal workers flooding into the D.C. metro after the war. Many of those flues have no clay tile liner at all, or the terra cotta is so badly deteriorated it no longer contains combustion gases. That’s not a repair observation, it’s a safety one.
The freeze-thaw cycles here do real damage. Temperatures cross 32°F multiple times a week through winter and early spring, and every crossing expands and contracts the mortar joints on exposed brick chimneys. Spalling brick faces and eroded crown mortar are common across Rockville. Pre-WWII homes near the Historic District often have their own issues: original masonry, shallow smoke chambers, and decades of deferred maintenance. Meanwhile the 1970s and 1980s townhome clusters across Rockville use factory-built zero-clearance inserts with prefab metal flues. Same day’s route can move from a Terra-cotta reline in Twinbrook to a metal chase inspection in a townhome off Rockville Pike.
Our Main Rockville Services
Rockville homeowners call us most often for three things: the annual cleaning and safety inspection, repairs to cracked or spalling masonry, and fireplace service work that keeps the system usable through the heating season.
Chimney Cleaning & Sweep in Rockville
Cleaning in Rockville means removing creosote buildup, scrubbing the flue walls, and running a camera down the full length of the chimney to check liner condition. In Twinbrook especially, a “cleaning” appointment frequently turns into a liner inspection conversation, because the original 1950s flues often have no clay tile liner or a cracked one. Every cleaning ends with a written photo record. Chimney Cleaning & Sweep in Rockville goes into more detail.
Chimney Repair in Rockville
Repair work here usually means tuckpointing crumbling mortar joints, rebuilding the crown, or fixing a smoke chamber that’s pulling poorly. Rockville winters accelerate mortar deterioration, so we flag joint erosion early and quote the repair in writing before any work starts. Chimney Repair in Rockville covers the full scope of what we see and fix.
Fireplace Services in Rockville
Fireplace service work spans gas log conversions, damper replacement, and prefab insert maintenance. Rockville’s townhome clusters call for factory-built system knowledge as often as masonry expertise, and our techs move between both in the same day. Fireplace Services in Rockville has the detail on what gets serviced and when.

BeforeAfterChimney Cap & Crown in Rockville
Chimney cap and crown work in Rockville starts with a simple truth: water is the enemy, and this city’s freeze-thaw cycles deliver it relentlessly. A cracked crown or missing cap lets rain and snow sit on the masonry, and every freeze pushes it further apart. In Twinbrook’s 1950s chimneys, the crown is often just a thin mortar wash, not a proper poured concrete cap, and it fails early. We install Chimney Cap & Crown systems that keep water out before it becomes a rebuild project.
Cap Installation
Signs you need it
Rainwater and bird activity inside the flue, or visible rust and debris on the smoke shelf during a cleaning.
What it costs in Rockville
Expect $185 to $640 for cap installation depending on flue size and material.
How we do it
We measure the flue opening, install a stainless cap sized to the tile, and seal the base with a weatherproof bond, documenting everything with photos.
Crown Repair
Signs you need it
Crumbling mortar along the crown edges, visible cracks, or water stains on the ceiling near the chimney.
What it costs in Rockville
Crown repair runs $450 to $1,400 in Rockville, depending on whether it’s patching or full re-pour.
How we do it
We remove the failed crown material, pour a new concrete crown with a proper overhang and drip edge, and slope it away from the flue to shed water.
What Chimney Cap & Crown Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Cap installation | $185 - $640 |
| Crown repair | $450 - $1,400 |
| Crown coating | $390 - $900 |
How do I know if my Rockville crown is failing?
Look for cracked or missing mortar along the crown edges, spalled brick faces near the top of the chimney, or water stains on the ceiling around the chimney chase. Call (240) 621-1264 for a camera inspection.
Can you install a cap on an older Twinbrook chimney?
Yes. The original 1950s flues often need a custom-sized cap because the terra cotta dimensions are no longer standard. We measure and fabricate to fit, then document the installation with photos.
Chimney Liner & Rebuild in Rockville
Chimney liner and rebuild work in Rockville usually starts with a camera scan that shows what the 1950s builders left behind: no liner at all, or terra cotta cracked in multiple planes. That’s what drives most of our Chimney Liner & Rebuild work in Twinbrook and Hungerford. A stainless steel liner gives the flue a continuous, insulated path for combustion gases, and a partial or full rebuild addresses masonry that’s structurally failing from decades of Rockville freeze-thaw cycles.
Stainless Steel Liner
Signs you need it
Missing or cracked clay tiles, smoke in the living space, or old mortar joints leaking combustion gases into the home.
What it costs in Rockville
A stainless steel liner runs $1,400 to $3,800 in Rockville depending on length and insulation requirements.
How we do it
We size the liner to the flue, insulate it as required for the appliance, and run it from the appliance collar to the crown, then document the route with camera footage.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or a crown that has completely separated from the masonry.
What it costs in Rockville
Partial rebuilds start around $2,500 and run to $6,000 depending on how many courses of brick come down.
How we do it
We tear down to sound masonry, rebuild the stack with proper mortar and flashing, and install a new crown and cap before the photo record is complete.
What Chimney Liner & Rebuild Costs in Rockville
| Item | Typical range in Rockville |
|---|---|
| Stainless steel liner | $1,400 - $3,800 |
| Liner replacement | $1,400 - $3,800 |
| Partial rebuild | $2,500 - $6,000 |
| Full chimney rebuild | $9,000 - $15,000 |
Does a 1950s Rockville chimney really need a liner?
In Twinbrook, frequently yes. The original chimneys were built without clay tile liners or with terra cotta that has since cracked. A stainless liner restores containment for combustion gases. Call (240) 621-1264 for a camera scan to verify yours.
How long does a liner installation take in Rockville?
Most stainless liner installations are completed in one day. Partial or full rebuilds take two to five days depending on the number of brick courses and weather windows.
