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.

Why Emberly Chimney Cleaners Is Silver Spring’s Preferred Chimney Cap & Crown Company
Silver Spring homeowners don’t call us because we’re the cheapest. They call because when we recommend a crown repair or a new multi-flue cap, we hand them the camera footage first. Our Chimney Cap & Crown in Silver Spring team has inspected hundreds of the post-WWII brick colonials and cape cods that dominate Woodside, Indian Spring, and the neighborhoods off Sligo Creek Parkway, and we know exactly what those chimneys look like inside after 70 years of freeze-thaw cycling.
Corrine Halstead, who leads our Silver Spring crews, puts it plainly: “If your crown has hairline fractures, the camera shows you the fractures. If your clay tile liner is spalled, you see the spalling. We don’t ask anyone to take our word for it.” That standard has been our practice since 2009. It’s also Clause 4 of the Haven Standard, which requires a documented photo record on every job. Every Silver Spring customer gets that record, along with a written scope and a written warranty before work starts. Background-checked, uniformed technicians arrive with their license information displayed, and you get a text when they’re on the way.
Our Chimney Cap & Crown Services in Silver Spring

Cap Installation
A standard single-flue cap installation in Silver Spring runs $220-$380, including the cap, mounting hardware, and labor. Most of the caps we install on older Silver Spring chimneys are stainless steel, sized to the flue dimensions we measure during the camera scan. For chimneys that were originally built for coal or oil boilers and later converted to gas, a correctly sized cap is the only thing keeping rain, birds, and squirrels out of a liner that was never designed for open exposure.
Cap Replacement
When an existing cap has rusted through, lost its mesh, or been knocked loose by a falling branch in the tree-heavy lots around Sligo Creek, replacement in Silver Spring typically costs $200-$420. We carry Famco and Copperfield caps in the sizes that fit older clay tile liners, which means we often complete the swap the same day we diagnose the problem. If your old cap was installed on a flue that’s now oversized for a gas appliance, we’ll show you that on camera and recommend a properly sized replacement.
Crown Repair
This is the service we recommend more than any other in Silver Spring, and the one where we see the most unnecessary upselling from other companies. A cracked crown that hasn’t yet caused structural damage can often be sealed and resurfaced for $700-$1,100 in Silver Spring. We use Gelco sealant for crown repair because it flexes with the thermal cycling that Silver Spring’s winters impose. No, you don’t always need a full crown rebuild. We’ll show you the camera footage and tell you plainly whether a repair is sufficient or a rebuild is genuinely required.
Crown Coating
For crowns that are intact but porous, a waterproof coating runs $350-$550 in Silver Spring. This is the preventive option for newer chimneys or ones that had crown repair done years ago. Silver Spring’s freeze-thaw pattern means moisture gets into even the smallest cracks, expands when temperatures drop below freezing, and widens those cracks over time. A coating now costs less than half of what a rebuild costs later, and the camera record gives you a baseline for future comparison.

Common Chimney Cap & Crown Problems We See in Silver Spring Homes

- Spalled clay tile liners from freeze-thaw cycling. Silver Spring’s winter temperatures oscillate around freezing repeatedly, which is harder on clay tile than consistent cold. Sharp edges from spalling catch debris, restrict draft, and can damage a new cap if not addressed. We photograph every tile during the Level 2 scan.
- Crowns cracked by thermal shock. Hairline fractures open on warm winter days and close again at night. Water gets in, freezes, and expands. In Four Corners and Woodside, we regularly see crowns where this cycle has dropped mortar chunks onto the roof. The camera shows the exact crack pattern before we recommend whether to seal or rebuild.
- Missing or undersized caps on converted gas flues. When an old oil boiler flue was repurposed for a gas insert, the liner often runs oversized and uncapped. Rain and animals get in, and the liner deteriorates from exposure it was never designed to handle. This is one of the most common inspection findings we document in Silver Spring, especially on cape cods and ramblers built between 1940 and 1965.
- Rusted cap mesh from Silver Spring’s humid summers. June through August brings humidity and heavy rain that sits in the mesh of older galvanized caps. Once the mesh fails, birds and wasps get in. Stainless caps last 12-20 years in Silver Spring’s climate. Galvanized caps often fail in 6-8.

FAQs - Chimney Cap & Crown in Silver Spring

Why does Montgomery County flag chimneys during HVAC or boiler replacement permits in Silver Spring?
Montgomery County inspectors now routinely flag chimneys when a homeowner pulls a permit for HVAC or boiler replacement, and the reason is specific to Silver Spring’s housing stock. Many of the post-WWII chimneys in neighborhoods like Woodside and Four Corners were originally built with a shared flue serving both a fireplace and an oil boiler. When the boiler was converted to gas, the flue became oversized for the single appliance, leaving an unlined or clay-tile-lined stack that no longer meets current venting requirements. If the county flags your chimney, the fix typically involves installing a properly sized stainless liner and cap, which in Silver Spring runs $1,500-$3,500 depending on the flue run. We document everything with the camera and provide the photo record the inspector wants to see. Call (980) 580-8641 if you’ve received a flagged inspection and need a written quote.
How does Silver Spring’s freeze-thaw pattern damage chimney crowns faster than colder climates?
In climates that stay below freezing all winter, water in the crown freezes once and stays frozen. In Silver Spring, temperatures cross the freezing mark dozens of times each winter. Water seeps into hairline cracks, freezes and expands, then thaws and drains deeper into the crack. Freeze again, expand again. That repeated cycling is what spalls clay tile liners and widens crown fractures in a matter of seasons, not decades. In a steadily cold climate, a crown with minor cracking might last ten more years. In Silver Spring, the same crown often needs repair within two or three. That’s why we recommend a camera-scan inspection before making any repair decision in this area.
Do I need a camera inspection before a cap or crown repair in Silver Spring?
Yes, and we won’t recommend any cap or crown work without one. The camera scan shows what’s actually happening inside the flue: whether the liner is intact, whether the crown cracks are superficial or structural, and whether the flue is properly sized for the appliance venting into it. In Silver Spring, where chimneys were frequently converted from oil or coal to gas, that last point matters more than in newer developments. We’ve seen customers told they need a new crown when the real problem was a failing liner, and vice versa. Clause 4 of the Haven Standard requires the photo record on every visit, and you see the same footage we see. No camera, no recommendation, no exception.
How often should Silver Spring homeowners replace chimney caps given the local climate?
A stainless steel cap in Silver Spring lasts 12-20 years. Galvanized caps fail much faster here because of our humid summers and freeze-thaw winters, often in 6-8 years. The mesh and the mounting hardware are the usual failure points. If you’ve got an older galvanized cap, or if you can see rust staining on the flue tiles from the ground, it’s worth a look. Schedule the camera-scan and we’ll tell you in plain terms whether the cap has life left or needs to go. Replacement runs $200-$420 for a standard cap, and we carry the sizes that fit Silver Spring’s older clay tile liners.
Can a cracked crown be repaired without rebuilding the whole chimney in Silver Spring?
In most cases, yes. A crown with hairline or moderate cracking but no evidence of structural shifting can be sealed and resurfaced with Gelco for $700-$1,100 in Silver Spring. Gelco flexes with the thermal expansion and contraction that causes most crown failures here, which is why we use it over rigid patch compounds. A full crown rebuild is only necessary when the crown has separated from the flue, has large missing sections, or when water damage has already spalled the underlying brick. We’ll show you the camera footage of the crown before you make any decision. If a competitor has told you that you need a full rebuild, bring us their written estimate and we’ll give you a free second opinion with our own camera documentation.
Get Your Silver Spring Chimney Inspected Before the Next Freeze Cycle
If your Silver Spring chimney is 40 years old or older and you don’t know the last time the cap or crown was inspected, the smart move is to find out now, before the next freeze-thaw cycle widens whatever cracks are already there. Call (980) 580-8641 and we’ll schedule a Level 2 camera-scan inspection, walk you through the photos, and give you a written price for any cap or crown work we recommend. You’ll have the evidence in hand before you spend a dollar. No pressure, no upsell, no guesswork.
