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.

AfterFast, Reliable Chimney Cap & Crown Across Northglenn
A chimney cap and crown repair in Northglenn typically runs $240-$680 for crown coating or replacement, and $180-$450 for cap installation depending on flue size and material. Most jobs we schedule in Northglenn are completed within one visit, with a written price in your hand before any work starts. If you’re seeing water stains near the fireplace, loose mortar on the chimney top, or hearing animals in the flue, call us at (980) 580-8641. We work across every Northglenn neighborhood, from the original 1960s tract off Malley Drive to the newer builds near the RTD N-Line.
Northglenn’s chimneys are not like Denver’s or Thornton’s. The city was built almost entirely in the 1960s as one of Colorado’s first master-planned communities, largely by Perl-Mack and a handful of other production builders. That means most chimneys here are now 50 to 60 years old, hitting the end of their original materials at the same time. The caps and crowns installed at construction have long since failed, and the freeze-thaw damage from Front Range Chinook winds has accelerated the breakdown. Our Chimney Cap & Crown team knows exactly what to look for on these aging stacks because we see the same construction DNA across hundreds of Northglenn homes every year.
Why Emberly Chimney Cleaners Is Northglenn’s Preferred Chimney Cap & Crown Company
We are not a franchise operation. Emberly Chimney Cleaners is independently owned and operated under the Haven Standard, and our crews serving Northglenn are background-checked, uniformed, and assigned to your job by name before we arrive. You get a text when the tech is on the way, and the tech who shows up is the tech whose license number is on your paperwork. Corrine Halstead, who leads our team, has built the company around one practice that most sweeps still do not do: camera documentation on every single visit, no exceptions.
Northglenn homeowners tell us the same thing about other chimney companies they have used: someone took a flashlight, looked up, said the crown was “bad,” and handed over a four-figure estimate with no evidence. We do not work that way. Clause 4 of the Haven Standard requires a documented photo record on every job, and we have held that standard since 2009, years before insurers started asking for it. When we tell you your Northglenn crown is spalling or your cap is rusted through, you will see the camera footage that proves it.
Our response time to Northglenn is typically 24 to 48 hours for non-emergency cap and crown work, and we answer the phone 24/7 with a live person, not a voicemail tree. Scheduling is coordinated from our Denver office, and our crews serve Northglenn locally, which means you are not waiting on a tech driving up from the Springs.
Our Chimney Cap & Crown Services in Northglenn
Here are the four services Northglenn homeowners call us for most, and what each one actually means for your chimney:
Cap Installation
A new chimney cap in Northglenn runs $180-$450 for a standard single-flue stainless cap, installed. If your original 1960s chimney never had a cap, which we see constantly on the older ranch homes near Community Center Drive, you are leaving the flue open to rain, snow, squirrels, and birds. We install caps from Copperfield and Famco, sized to your flue tile, not a universal fit that wobbles in the wind.
Cap Replacement
If your existing cap is rusted, dented from hail, or the mesh is torn, replacement is usually a one-hour job. In Northglenn, we see a lot of caps corroded from the inside out because glazed creosote from the original unparged smoke chambers pushes moisture up against the metal. We will scope the flue with a camera before we replace the cap so you are not putting a new lid on a hidden fire risk.
Crown Repair
The chimney crown is the concrete slab on top of the chimney, and on Northglenn’s 1960s homes the original mortar crowns are typically cracked, crumbling, or missing entirely. A crown rebuild runs $380-$680 depending on chimney size and access. We use a proper poured crown with an overhang and a drip edge, which the original Perl-Mack builders never installed. If water is getting through the crown, it is destroying the flue liner below it, and a new cap alone will not fix that.
Crown Coating
For crowns that are still structurally sound but porous and cracking, we apply a flexible crown coating, usually Gelco or HeatShield, at $240-$480. This is the service we recommend most often in Northglenn because the crowns here fail from freeze-thaw spalling long before they fall apart completely. The coating seals hairline cracks and prevents water infiltration without a full tear-out. But we will not coat a crown that is already breaking loose. The camera and a hammer test tell us which one you have.

BeforeAfterTrusted Brands We Service in Northglenn
We stock and install caps and crown materials from Copperfield, DuraFlex, and Gelco, procured through Haven’s buying network to keep Northglenn customers’ prices honest. These are not bargain-bin parts. Copperfield makes the multi-flue and custom caps we install on Northglenn split-levels with two fireplaces. Gelco’s crown coating is what we use on original 1960s crowns that the Chinook winds have chewed up. Because we stock these locally through our Denver office distribution, turnaround in Northglenn is fast, usually same-week once we have scoped the flue and taken the measurements.
Common Chimney Cap & Crown Problems We See in Northglenn Homes
- Chinook freeze-thaw crown spalling. Northglenn sits at roughly 5,400 feet on the exposed Front Range, where Chinook winds can swing temperatures 40 to 50 degrees in hours. Water seeps into the crown’s hairline cracks, freezes, expands, and pops the mortar loose. After 50 years of that cycle, most original crowns here are rubble.
- Undersized, unparged smoke chambers pushing creosote up against the cap. Because Perl-Mack and other 1960s Northglenn builders used a handful of standard chimney designs across thousands of homes, the smoke chamber behind nearly every original fireplace is unparged and corbelled to an undersized flue. That turbulence pushes creosote and moisture up against the cap and crown, corroding standard single-flue caps years before they should fail.
- Missing or rusted caps on homes that never had them. A surprising number of original Northglenn chimneys were built without exterior caps, relying on the damper to keep weather out. Dampers warp after 50 years of firebox heat. Once that happens, the flue is open to rain, animals, and debris from the mature cottonwoods around neighborhoods like Fox Run and Karl’s Farm.
- Clay tile flue liners spalling from five decades of freeze-thaw. The original clay tile liners in Northglenn’s 1960s chimneys are cracking apart. Those chips fall down into the smoke shelf, and the gaps in the liner let heat and moisture reach the brickwork. On a split-level off Malley Drive, our tech found the original clay tile liner spalled from five decades of Chinook freeze-thaw swings and the chimney crown crumbled to loose mortar. We installed a custom Copperfield multi-flue cap and rebuilt the crown with a Gelco coating after camera-scoping the flue to confirm no third-degree creosote glaze hid behind the damper.
Pricing for Chimney Cap & Crown in Northglenn, CO
Here is what you can expect to pay in Northglenn, based on the work we have done across the city:
- Standard single-flue cap installation: $180-$320
- Multi-flue or custom cap (typical for split-levels with two fireplaces): $350-$550
- Crown coating with Gelco or HeatShield: $240-$480
- Full crown rebuild with poured concrete and drip edge: $380-$680
- Combined cap replacement + crown rebuild: $520-$950
What changes the price? Flue size, roof pitch, chimney height, and whether the crown needs coating or full replacement. A single-story ranch off 104th Avenue with a standard flue is a faster job than a two-story split-level on a steep pitch. Every quote is written before work starts, and the scope is itemized. No one from our company will ever give you a quote that says “chimney work” without a dollar figure and a line-item description. Call (980) 580-8641 for a free estimate. If you have a written quote from another company, bring it. We offer a Free Second Opinion on any written estimate, and we will show you the camera evidence for everything we recommend.

FAQs - Chimney Cap & Crown in Northglenn
Because the original mortar crowns were installed without a drip edge or overhang, and five decades of Chinook freeze-thaw cycles have cracked them beyond what a cap alone can fix. A new cap keeps rain out of the flue, but water still seeps into the crown’s cracks, freezes, and spalls the mortar apart. Coating seals those cracks before they become structural failures. Call (980) 580-8641 and we will scope the crown and tell you whether coating is enough or a rebuild is needed.
A custom cap can reduce wind-induced downdrafts, but it will not fix turbulence caused by an undersized smoke chamber. What it can do is buy you time while you decide on a proper smoke chamber parging or a liner replacement. The camera scope will show you exactly how much creosote and turbulence damage is happening at the cap level. We will not sell you a cap as a draft fix unless the scope proves it is the right call. Call (980) 580-8641 for a free estimate.
A standard cap covers one flue tile. A multi-flue cap spans the entire top of the chimney and covers multiple flues with one unit. Northglenn split-levels often have two fireplaces or a fireplace plus a furnace flue stacked in the same chimney. The multi-flue cap we install from Copperfield covers both flues and fastens across the crown, which also helps stabilize a crown that is already cracking. Call (980) 580-8641 and we will measure your chimney top and show you the difference in writing.
It will help by blocking the downdraft that pushes the smell into the house, but the smell itself is coming from Stage 2 or Stage 3 glazed creosote inside the flue, which we see constantly in Northglenn because the semi-arid climate encourages intensive wood burning during cold snaps. A cap without a proper sweep and possible liner treatment is a partial fix. The camera scope during our Level 2 inspection shows you exactly where the glaze is and what it will take to remove it. Call (980) 580-8641 and we will put eyes on it.
Look for loose mortar or sand-like granules on the roof or at the base of the chimney, hairline cracks you can see from the ground, or spalling brick faces near the top. Inside, water stains on the ceiling near the fireplace or a musty smell in the firebox after rain are late-stage signs. By the time you see interior water damage, the crown has been failing for years. The earlier you catch it, the more likely a coating is enough instead of a rebuild. Call (980) 580-8641 and we will do a camera-scoped inspection and hand you the photo record before you spend a dollar.
