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.

AfterLevel 2 Inspection in Boulder, CO
A Level 2 chimney inspection in Boulder means a camera goes down the flue – not just a flashlight pointed at the firebox opening. The NFPA 211 standard defines Level 2 as the minimum required any time a home changes hands, after any event that may have affected the chimney’s structure (a chimney fire, a hard freeze-thaw season, or a seismic event), or before installing a new appliance or liner. At Emberly Chimney Cleaners, that camera scan isn’t an upgrade you have to ask for: it’s on every inspection by default, along with a written price before anyone starts work and a documented photo record when they finish.
If you bought a home in Boulder between 2015 and 2025, there’s a reasonable chance the chimney was “inspected” with a mirror and a flashlight. That passes as a Level 1 inspection on paper, but it leaves the flue liner, smoke chamber, and upper firebox largely unseen. We’ve been doing this since 2009 – more than 38,000 chimneys inspected and Chimney Cleaning & Sweep – and the pattern we see in Boulder is consistent: homes that went through a real estate transaction with only a visual inspection often have liner cracks, mortar deterioration, or creosote staging that wasn’t documented and therefore wasn’t negotiated at closing.
To book a Level 2 inspection or get a written price in advance, call us at (970) 598-0453. A live person picks up, 24 hours a day, 7 days a week. This service is part of our full Chimney Cleaning & Sweep in Boulder program, and it pairs naturally with a sweep when the inspection identifies creosote buildup or debris.
When You Need a Level 2 Inspection
- You’re buying or selling a Boulder home. NFPA 211 explicitly lists property transfer as a Level 2 trigger. A Level 1 visual won’t satisfy most insurers or lenders who’ve read the standard carefully, and in Boulder’s older neighborhoods – Mapleton Hill, Whittier, Martin Acres – the chimneys are often original to the structure.
- You had a chimney fire, even a small one. A fast-burning creosote event can fracture a clay flue liner without leaving visible evidence at the firebox. Camera footage is the only way to confirm the liner is still sound after any thermal shock.
- You’re switching fuel types or installing a new insert. A wood-burning fireplace being converted to gas, or a new high-efficiency insert being fitted to an older clay-tile flue, requires a Level 2 before the installation – both by NFPA 211 and by most manufacturer warranties on the insert itself.
- Boulder’s freeze-thaw seasons have been working on your masonry. At Boulder’s elevation, the shoulder seasons run long. Repeated freezing and thawing inside mortar joints and clay flue tiles causes spalling – where the tile face fractures off – and hairline cracks that let combustion gases migrate into the chase or wall cavity.
- Your home inspector flagged the chimney but didn’t use a camera. A general home inspector checking “chimney: functional” on a report is not a chimney inspection. That checkbox doesn’t get into the flue liner, smoke chamber corbeling, or the condition of the rain cap and crown.
- More than three years have passed since the last documented inspection. If you can’t produce a written inspection report with a date, photos, and findings, you don’t know what you have. That matters for insurance claims as much as it does for safety.
Our Level 2 Inspection Process
Here’s exactly what happens when a Emberly technician arrives at your Boulder home. The steps below follow the NFPA 211 Level 2 scope, which is the same standard your insurer and your municipality’s fire marshal reference.
- Written price and scope before we start. Haven Standard Clause 1 – what we call the “Have it in writing” clause – means you receive a written price, written scope of work, and written warranty before the technician does anything. No surprises once someone is already inside your home.
- Exterior and accessible structural inspection. The technician walks the roofline and examines the crown (the concrete cap at the top of the chimney stack), the flashing where the chimney meets the roof deck, the mortar joints in the brick or stone chase, and the chimney cap. In Boulder, the cricket – the small angled diverter behind a wide chimney – is worth checking specifically because the debris load from cottonwood and pine in neighborhoods like Newlands and University Hill can dam water against the flashing and push it under the cap.
- Firebox and smoke chamber inspection. Inside, we inspect the firebox floor, walls, and back panel for cracks or spalling refractory brick, the damper frame and plate for warping or corrosion, and the smoke chamber above the damper – which is the area most home inspectors skip entirely because you can’t see it from the firebox opening without a light and a mirror at minimum.
- Camera scan of the flue liner – full length. This is the part that distinguishes a Level 2 from every other inspection. A camera travels the entire flue from the firebox to the top of the stack. We’re looking at the flue liner’s interior face for cracks, open joints, offset sections, missing mortar, and creosote classification. Clay tile liners crack at the joints; that’s where gases find a path. Stainless steel liners from a prior installation – DuraFlex flex liner, for example – get inspected for deformation, separation at the connection points, and proper termination at both ends.
- Creosote assessment and classification. If there’s creosote present, we classify it: Class I (light, brushable flaky deposits), Class II (harder tar-like glaze), or Class III (a thick, concentrated glaze that has likely experienced fuel-rich smoldering). Class III is a fire hazard and requires chemical treatment – typically a HeatShield or rotary-brush protocol – before a standard sweep can be effective. You’ll know the class from this inspection before any work is quoted.
- Documented photo record delivered to you. Clause 4 of the Haven Standard requires a documented photo record on every job. You’ll receive the camera footage and photos from the inspection – not a verbal summary, not a check-the-box form. If you need to file an insurance claim, negotiate a repair credit on a home purchase, or simply want to know what changed between inspections, you’ll have the documentation to back it up. This practice has been standard at Emberly since 2009.
BeforeAfterLevel 2 Inspection Pricing in Boulder
A Level 2 inspection in Boulder typically runs $199 to $349, depending on the chimney configuration. The range reflects real variables, not arbitrary pricing. Here’s what moves the number:
- Single flue vs. multiple flues: A standard single-flue chimney is at the lower end. A chimney with two or three flues – common in older homes in Boulder’s Table Mesa and Baseline neighborhoods where wood-burning fireplaces were paired with boiler or furnace flues – takes more camera time and costs more.
- Accessibility: A low-pitch roof with a safely accessible chimney is straightforward. A steep pitch, a two-story chimney chase set back on a roofline, or a chimney requiring a ladder setup beyond a standard extension adds technician time.
- Inspection only vs. inspection plus sweep: If the inspection finds creosote buildup or debris and you want the sweep done the same visit, that is priced separately and quoted in writing before the sweep starts. Many customers book both together; the inspection informs the sweep scope, so there’s no redundancy in the work.
- Real estate transaction inspections: When a Level 2 is being done for a home purchase or sale, we note that in the report. Buyers’ agents and real estate attorneys in Boulder have found the documented photo record – especially the camera footage – useful in repair credit negotiations. We’ll work with your timeline.
You will have a written price before anything starts. That’s not a policy we apply selectively – it’s the only way we operate. If you’ve received a written estimate from another company, bring it to us. We offer a free second opinion on any written quote, and we’ll tell you plainly whether the scope matches the price.

What the Camera Finds That a Flashlight Misses
In Boulder specifically, there are a few conditions we see often enough that they’re worth naming directly.
Clay tile liner failures are common in homes built before 1990. The tiles are joined with refractory mortar, and after decades of thermal cycling – hot fires expanding the tiles, Colorado winters contracting them – the mortar at the joints deteriorates. A hairline crack at a joint lets combustion gases, including carbon monoxide, migrate into the wall cavity. The camera shows the crack; a flashlight angled from the firebox opening doesn’t reach those joints.
Smoke chamber corbeling – the angled brickwork that transitions the wide firebox opening into the narrow flue – often has open mortar joints that aren’t visible from below. Corbeled smoke chambers in homes built before 1990 predate parged (smooth-coated) standards, and the stepped brick surfaces trap creosote at every ledge. The camera shows the deposit pattern; the technician can tell you whether a standard brush can clear it, whether Soot Removal requires specialized tools, or whether a HeatShield resurfacing product is warranted.
After a particularly hard winter in Boulder – where freeze-thaw cycles run from October through April at the city’s 5,430-foot elevation – spalling at the crown is common. The crown is the mortar or concrete cap that sheds water off the top of the stack. When it cracks, water gets into the chase. We’ve seen cases in the Panorama Heights and Shanahan Ridge neighborhoods where a crown that looked intact from the ground had fractures significant enough to redirect runoff into the upper flue. That shows up in the photo record from the exterior walk.
The Haven Standard and What It Means for You
Emberly Chimney Cleaners operates under the Haven Standard, which is a set of documented operating principles, not a marketing phrase. The clauses most relevant to a Level 2 inspection are:
- Clause 1 (Have it in writing): Written price, written scope, written warranty before work starts.
- Clause 4 (Documented record): Camera footage and photos on every inspection, archived and delivered to the customer.
- 365-Day Done Right Promise: If the inspection or any resulting work isn’t done right, we make it right. That’s documented, not verbal.
Background-checked, uniformed technicians are assigned by name before the appointment, and you’ll receive a text when they’re on the way. If something in the process doesn’t go as described here, that’s a problem we want to hear about directly at (970) 598-0453.
Level 2 Inspection vs. Level 1: What’s the Difference?
A Level 1 inspection covers the accessible portions of the chimney – what can be seen from the firebox opening and from the ground outside. NFPA 211 describes it as appropriate for a chimney that hasn’t changed, is running the same appliance, and has no reason to suspect a problem. It’s a maintenance check, not a diagnostic tool.
A Level 2 inspection adds camera access to the full interior of the flue, inspection of accessible attic and crawlspace areas around the chimney, and a closer look at the structural connections. It’s what the standard requires at sale, after any event that may have damaged the system, or before any change in appliance or fuel type.
The distinction matters in Boulder because the real estate market moves fast, and a Level 1 check at a home inspection often gets filed under “chimney: passed” without anyone noting that it wasn’t a Level 2. We’ve seen buyers close on homes in Gunbarrel and East Boulder with documented chimney inspections that were, in fact, Level 1 visual checks – leaving liner cracks and Class II creosote undisclosed because the camera was never deployed.

FAQs – Level 2 Inspection in Boulder
How much does a Level 2 chimney inspection cost in Boulder?
A Level 2 inspection in Boulder runs $199 to $349 for most single-flue chimneys, with the exact price depending on the number of flues, roof accessibility, and whether an Annual Sweep is being added at the same visit. You’ll have a written price before the technician does anything. Call (970) 598-0453 for a specific quote – estimates are free and we’ll give you a number on the call.
Is a Level 2 inspection required when buying a home in Boulder?
NFPA 211 designates a Level 2 inspection as the minimum required upon any real estate transfer. Your lender or insurer may have their own requirements that reference the same standard. A Level 1 visual check by a general home inspector does not meet this threshold, and the documentation difference – camera footage vs. a checkbox – can matter significantly if a defect surfaces after closing. We note transaction context in the written report and can work within a closing timeline.
What exactly do I get when the inspection is done?
You receive a written inspection report, camera footage of the flue interior, and photographs of the exterior components – crown, cap, flashing, and visible masonry. That documentation is yours; it doesn’t expire and it’s useful for insurance purposes, contractor bids, and future inspections that want a baseline. This is Haven Standard Clause 4, and it applies to every inspection Emberly completes – it’s not an add-on package.
Can a Level 2 inspection be done the same day as a chimney sweep?
Yes. Many customers book both together, which makes practical sense: the inspection tells us exactly what the flue contains before the sweep begins, so the technician arrives with the right tools for the creosote class identified. The inspection is completed and priced first, the sweep is quoted separately in writing, and you approve the sweep before it starts. Call (970) 598-0453 to schedule both – we’ll confirm what’s available in your area of Boulder.
