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.

We know the chimneys in Derry Village differently than a company that drives up from Boston and treats them like any other stack. The village core is dense with 18th and 19th century colonials and cape cods, many with original multi-flue masonry chimneys that have been repurposed, sealed off, and sometimes reopened across two centuries of heating changes. That history matters when you’re deciding whether a cap replacement is simple or whether the crown underneath needs rebuilding first.
Why Emberly Chimney Cleaners Is Derry Village’s Preferred Chimney Cap & Crown Company
Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, and every single one included a written price before work started and a documented photo record when it was done. That’s not an add-on. Clause 4 of the Haven Standard requires a camera scan on every visit, and we’ve run that archive continuously for 16 years. When we tell a Derry Village homeowner their crown is spalling or their flue has first-degree creosote, we show them the footage. Not a summary. The actual images.
Corrine Halstead leads the team, and the technicians who arrive at your door are background-checked and uniformed, with license information displayed before work begins. You get a text when they’re on the way, a live person answers the phone 24/7, and the price on the written estimate is the price you pay. If a crown looks fine on camera but a competitor’s quote says it needs $3,000 of work, bring us that quote. We’ll do a Free Second Opinion and show you what we see either way.
Our Chimney Cap & Crown Services in Derry Village
Cap Installation
A new cap on a Derry Village flue does two things: keeps rain and animals out, and stops downdrafts from pushing smoke back into the room. We install caps sized to the actual flue tile, not a generic box that sits loose. For older chimneys off East Broadway or near the village center, that often means measuring each flue individually because 1800s masons didn’t build to modern uniform dimensions.
Cap Replacement
When a cap rusts through or blows off in a nor’easter, replacement usually runs $220-$480 depending on flue size and material. We check what’s underneath before swapping anything. On a Derry Village colonial where the cap has been missing for a season or more, the flue below is often full of leaves, nests, or deteriorated mortar from the crown above. We document it, quote it in writing, and fix the whole stack, not just the visible piece.
Crown Repair
Crown work is where Derry Village chimneys show their age. The original crowns on many 18th and 19th century stacks were poured from soft lime mortar that erodes under southern NH’s freeze-thaw cycling. Once water gets through the crown, it moves into the brick below and begins spalling: the face of the brick pops off from internal ice expansion. We rebuild crowns with proper bonding material and a drip edge that sheds water away from the masonry, not into it.
Crown Coating
Coating has a place, but not as a shortcut over crumbling mortar. We see chimneys in Derry Village where a previous contractor painted a sealant over a failing crown and called it done. Water kept moving through the cracks underneath while the coating hid the damage. Our rule is simple: if the crown is structurally cracked, we remove and rebuild it. Coatings are for sound crowns that need a moisture barrier, and we document the condition on camera before and after.
This page covers cap and crown work specifically. If you need a full inspection of the flue liner or the firebox, see our Chimney Cap & Crown service hub for the complete scope we offer across New Hampshire.

BeforeAfterTrusted Brands We Service in Derry Village
We install Famco and Copperfield caps because they hold up to southern NH weather, and we stock common sizes for fast turnaround on Derry Village jobs. For crown repair and rebuilds, we use Olympia Chimney masonry products sourced through Haven’s buying network, which keeps materials costs predictable. When a custom cap is needed for a multi-flue colonial with non-standard flue spacing, we order exact-fit pieces rather than forcing a universal box onto a 200-year-old stack.
Common Chimney Cap & Crown Problems We See in Derry Village Homes
- Sealed flues reopened for wood stoves. A Derry Village colonial often had one flue capped and sealed when an oil furnace was replaced by forced air. Years later, the homeowner adds a wood stove insert to that dormant flue without inspecting it first. We’ve opened caps on flues like this and found bird nests, loose mortar, and creosote coating the clay tile from use decades ago. Never connect an appliance to a flue that hasn’t been camera-scanned.
- Soft lime mortar crowns eroding. Original 1700s and 1800s crowns weren’t poured with Portland cement. They were lime mortar, which dissolves slowly under repeated rain, snowmelt, and freeze-thaw cycling. The result is a crown that looks solid from the ground but crumbles when touched. Water moves through it, into the flue, and into the brick below.
- Improperly sized caps on dormant flues. When a flue was sealed off, a previous owner or a handyman often installed a cheap cap without checking flue dimensions. Rain and animals get in, debris accumulates, and when the flue is reactivated, the draft is blocked or smoke backs up. We see this pattern repeatedly in the dense older housing around the historic Derry Village core.
- Coating over failed crowns. A sealant applied over a crown that’s already cracking will buy one season at most, then trap moisture inside the mortar as temperatures swing. Southern NH’s freeze-thaw cycles, where temperatures cross the freezing point repeatedly from November through March, accelerate the damage. The coating becomes a moisture trap, and the spalling gets worse underneath it.
Pricing for Chimney Cap & Crown in Derry Village, NH
A straightforward cap replacement in Derry Village runs $220-$480. Custom multi-flue caps for older colonials with uneven flue spacing run $600-$1,100. Crown repair or rebuild typically runs $450-$900 depending on the extent of mortar removal and whether we’re pouring a new crown from scratch. Crown coating on a sound crown runs $180-$320 after inspection confirms the structure is intact.
What determines where you land in those ranges: flue count, crown material condition, roof access from a safe ladder setup, and whether we discover damage inside the flue during the camera scan. That last part is the one a generic quote over the phone can’t account for. We don’t quote blind. We inspect, document, and write the price. If we find a dormant-flue issue like the ones described above, we show you the footage before any recommendation is made.

FAQs - Chimney Cap & Crown in Derry Village
Because the original crowns on 18th and 19th century stacks in Derry Village were poured from lime mortar that erodes under freeze-thaw cycling, and a cap installed on an eroded crown won’t stop water from entering the flue. We rebuild the crown first, then install the cap. Call (980) 580-8641 to schedule a camera inspection so you can see the crown condition before anyone recommends work.
No, not without a camera scan first. In Derry Village we regularly open caps on dormant flues and find bird nests, loose mortar, and creosote coating the tile from decades ago. Connecting a wood stove to that flue without cleaning and inspecting it is a chimney fire risk. We inspect, document, clean if needed, and then cap the flue properly. Call (980) 580-8641 for a written quote.
A custom multi-flue cap sized to the actual flue dimensions, not a universal box. The flue spacing on older Derry Village chimneys varies from stack to stack because 1800s masons built to the house, not to a standard. We measure each flue, order or fabricate a cap that covers all of them with proper spark arrestor mesh, and document the fit on camera. Call (980) 580-8641 and we’ll show you what your chimney actually needs.
Southern NH’s freeze-thaw cycle, with temperatures crossing the freezing point repeatedly from November through March, drives water into the smallest crown cracks and then expands it as ice. That expansion widens cracks, breaks off brick faces, and loosens cap mounts. Nor’easter moisture loading makes it worse because the water is already inside the masonry when the temperature drops. A crown that leaks in January was damaged by last winter’s cycling. Call (980) 580-8641 for a free estimate on crown repair or replacement.
Yes. Clause 4 of the Haven Standard requires a camera scan on every visit, and for good reason: what sits underneath the cap is often the real problem. On a Derry Village colonial off East Broadway, our tech opened a cap installed over a flue the homeowner believed was dormant and found a bird nest, loose mortar, and first-degree creosote. The flue had been sealed when the original oil furnace was replaced, and the homeowner had just connected a wood stove insert to it. Without the camera, we’d have swapped a cap and missed a chimney fire waiting to happen. Call (980) 580-8641 for a free inspection and written quote.
