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 Silver Spring, MD
Chimney cap and crown work in Silver Spring is the difference between a flue that sheds water and one that slowly absorbs it until the masonry fails. Homes here, most built between 1938 and 1965, carry chimneys with original clay tile liners and mortar that freeze-thaw cycles have been working on for six or seven decades. A camera scan shows you exactly where you stand before you spend a dollar. Call (571) 376-7052 to book one.
Why Silver Spring Homes Are Different
Silver Spring’s housing stock is a specific artifact of the post-WWII federal-worker boom: dense blocks of brick colonials, Cape Cods, and split-levels in Woodside, North Woodside, Sligo Park Hills, and Kemp Mill, most built between 1938 and 1965. The chimneys on these homes were sized for coal or wood, then informally converted for oil and gas furnaces without proper relining. That means a large share of Silver Spring chimneys still run a fireplace and a furnace through the same original clay tile flue, now 60 to 80 years old and frequently cracked or offset.
Winter brings 15 to 20 freeze-thaw cycles per year, and the soft, high-lime mortar used in 1940s and 1950s construction absorbs water each time, then fractures as it freezes. Spalling brick faces and eroding crowns are endemic across the older neighborhoods. Summer humidity then drives moisture into those microcracks. The result: a chimney system that looks fine from the street but is quietly moving water toward the flue, the smoke chamber, and eventually the ceiling below.
There is also a hard seasonal constraint. Federally protected chimney swifts nest in Silver Spring’s older unlined masonry chimneys from May through October. Once they are in, work legally cannot proceed under the Migratory Bird Treaty Act. The practical window for inspection and repair is February through April, before the birds return, or November. Waiting until fall usually means another season of deferred maintenance.
Our Main Silver Spring Services
These are the three jobs Silver Spring homeowners call us about most, each with its own dedicated page for the full detail.
Chimney Cleaning & Sweep in Silver Spring
A standard sweep in Silver Spring means removing creosote and soot from a flue that has likely been in service since the 1940s or 1950s. We run a camera down the flue after every cleaning to document liner condition, because on homes of this era the cleaning often reveals damage the soot was hiding. If the flue is clear, you get photos and a written report. If it is not, you see the cracks yourself before we discuss repair. Full details on Chimney Cleaning & Sweep in Silver Spring.
Chimney Repair in Silver Spring
Repair work here usually starts with a crown or a flue, not a full rebuild. The freeze-thaw damage concentrated in Silver Spring brickwork shows up first as hairline crown cracks and spalled brick faces, which are fixable early for a fraction of what a rebuild costs. We write the scope and price before anyone starts, and you get a photo record of every step. Full detail on Chimney Repair in Silver Spring.
Fireplace Services in Silver Spring
Older Silver Spring fireplaces often need attention to the damper, the smoke chamber, or the firebox before they are safe to use again. We inspect with a camera, show you the footage, and quote the work in writing. If the fireplace is decorative-only and safe as is, we will tell you that plainly.

BeforeAfterChimney Cap & Crown in Silver Spring
Most Silver Spring chimneys we inspect have either no cap at all, or a rusted cap that stopped shedding rain years ago. The crown beneath it, poured from soft 1940s-era mortar, has usually begun to erode in the freeze-thaw cycle. That is the entry point for nearly every brick and liner problem we find in Woodside, Sligo Park Hills, and the surrounding blocks. See our full Chimney Cap & Crown service hub for a deeper dive.
Cap Installation
Signs you need it
No cap, a rusted cap, or animal debris at the base of the flue.
What it costs in Silver Spring
$145 to $475 installed, depending on flue size and cap type.
How we do it
Measure the flue, mount the correct cap, seal it, and photograph the finished install.
Crown Repair
Signs you need it
Hairline cracks, crumbling mortar at the crown edge, or standing water on the crown after rain.
What it costs in Silver Spring
$255 to $575 for repair; $95 to $220 for a crown coating when the structure is still sound.
How we do it
Clean the crown, fill and seal cracks, and apply a water-resistant coating so rain stops soaking the masonry below.
Multi-Flue Cap
Signs you need it
Two flues sharing one chimney crown, especially common on Silver Spring homes where a fireplace and furnace share the stack.
What it costs in Silver Spring
$275 to $650 depending on flue dimensions and cap material.
How we do it
Custom-fit a cap that covers both flues on a single crown, with a screened edge and full photo documentation.
What Chimney Cap & Crown Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Cap installation or replacement | $145 - $475 |
| Crown repair | $255 - $575 |
| Crown coating | $95 - $220 |
Can you install a cap without cleaning first?
Yes. A cap install does not require a sweep, but we will camera-scan the flue while we are up there so you can see its condition. The scan is part of the visit.
Do I need a cap if my chimney is unused?
Usually yes. An uncapped flue lets rain, animals, and debris into the masonry, and water damage continues whether the flue is used or not. Call (571) 376-7052 for a written quote.
Chimney Liner & Rebuild in Silver Spring
In Silver Spring, the liner conversation starts with an uncomfortable fact: most clay tile flues installed between 1938 and 1965 were never sized for the furnace conversions that happened in the 1970s and 1980s. We regularly pull cameras through flues in Woodside and Kemp Mill and find cracked or offset joints, gaps where flue gases have been escaping into the masonry for years. A Chimney Liner & Rebuild is often the only fix that restores the flue to a safe condition.
Stainless Steel Liner
Signs you need it
Cracked clay tiles visible on camera, or a flue serving a gas or oil furnace without a proper liner.
What it costs in Silver Spring
$1,835 to $4,600 installed, depending on flue height and diameter.
How we do it
Remove the old liner where needed, drop a DuraFlex or Olympia Chimney stainless liner, insulate and cap it, and document the full run with photos.
Liner Replacement
Signs you need it
Visible gaps at the tile joints, flue gas stains on the interior masonry, or a furnace flue that predates current code.
What it costs in Silver Spring
$1,835 to $4,600, matching the stainless liner range above.
How we do it
Run the camera, show you the damage, then replace the liner with a properly sized stainless system and a written warranty.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, a leaning stack, or crown failure that has let water into the top courses.
What it costs in Silver Spring
$1,100 to $2,500, depending on how many courses need rebuilding.
How we do it
Remove the damaged courses, relay them with proper mortar, reflash where needed, and photograph each stage.
What Chimney Liner & Rebuild Costs in Silver Spring
| Item | Typical range in Silver Spring |
|---|---|
| Stainless steel liner install | $1,835 - $4,600 |
| Liner replacement | $1,835 - $4,600 |
| Partial rebuild | $1,100 - $2,500 |
Can I just patch the liner instead of replacing it?
No. A patch on a cracked clay tile liner does not address the movement and gas escape happening at the joints. In Silver Spring’s freeze-thaw climate, patches fail quickly.
How do I know the liner is actually damaged?
You watch the camera footage with us. We show you every crack, gap, or offset joint in the flue before you decide anything. Call (571) 376-7052 to schedule a scan.

Most Silver Spring appointments are booked within one to two weeks, and February through April is the fastest window. The chimney swift nesting season runs May through October, which legally restricts some work, so early spring is the best time to schedule.
