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 1 Inspection in Denver, CO
A Level 1 chimney inspection in Denver covers every accessible part of your chimney system – the firebox, damper, smoke chamber, flue liner, and exterior crown and cap – with a visual check to confirm everything is structurally sound and clear for use. Most homeowners in Denver need one annually, and the inspection typically takes 45 to 60 minutes. At Level Two Chimney Denver, a written price comes before any work starts, and you leave with a documented photo record of what we found.
If you’re looking at this page, you probably have a fireplace you want to use safely this season, or a home purchase coming up and a chimney that needs to be vetted before the inspector’s report lands. Either way, this is where that starts. Our Chimney Cleaning & Sweep in Denver service almost always begins here, because we won’t sweep a chimney we haven’t looked at first. Call us at (720) 674-7312 – a live person picks up, any hour.
Denver’s climate puts real stress on masonry. The freeze-thaw cycles between October and April crack crowns, push mortar joints apart, and work moisture into flue liners in ways that aren’t obvious from the fireplace side. A Level 1 inspection catches those problems while they’re still small. We’ve completed more than 38,000 chimney inspections and Chimney Cleaning & Sweep services since 2009, every one with a written price before the first brush stroke and a photo record when it’s done.
When You Need a Level 1 Inspection
NFPA 211 – the National Fire Protection Association’s standard for chimneys, fireplaces, and venting – calls for a Level 1 inspection at least once a year on any chimney in regular use. That’s the baseline. Several other situations make one necessary even if you had one last year.
- You’re buying or selling a home in Denver. Sellers in neighborhoods like Congress Park and Wash Park routinely see inspection contingencies that include the chimney. A Level 1 from a documented provider gives buyers something concrete – not just “we looked at it.”
- You burned wood last winter and want to use the fireplace again this fall. A season of regular wood fires builds creosote – a tar-like deposit that forms in three grades. Class I is flaky and brushes out; Class III is glazed and requires chemical treatment before any sweep can remove it safely. You won’t know which you’re dealing with until someone looks.
- You’ve noticed a smoky smell in the house when the fireplace isn’t in use. In Denver homes with older clay tile liners, a cracked flue section can let combustion gases seep into the living space even between fires. That smell is a flue liner problem until proven otherwise.
- There was a chimney fire, even a small one. Chimney fires often go undetected – homeowners hear a rumble or see elevated smoke and assume it stopped on its own. The heat can crack the liner and warp the damper. This scenario technically triggers a Level 2 inspection under NFPA 211, but a Level 1 walk-through confirms whether to escalate.
- Your home sat vacant, or you didn’t use the fireplace last season. Unused chimneys in Denver’s foothills-facing neighborhoods – Hilltop, Montclair, and Crestmoor among them – see wildlife nesting in caps and crowns more often than you’d expect. Starlings and squirrels build nesting material that blocks draft completely.
- You had any masonry work done near the chimney in the last 12 months. New flashing, a crown repair, or even attic work above a shared wall can shift the liner joints. A visual check after any adjacent work is cheap insurance.
Our Level 1 Inspection Process
Here’s exactly what happens when a Level Two technician arrives at your Denver home for a Level 1 inspection. The steps follow NFPA 211 and our own Haven Standard documentation requirements – nothing is optional, nothing is skipped because it adds time.
- Written price and scope before we start. Before any inspection begins, you receive a written quote with a flat price, a clear scope of what’s included, and the warranty that backs it. That’s Haven Standard Clause 1 – it doesn’t change if we find more than expected. If additional work is needed, you get a separate written price for that before we touch anything.
- Exterior check: crown, cap, flashing, and mortar joints. The technician walks the exterior and inspects the chimney crown (the concrete or mortar cap that covers the top of the masonry) for cracking and spalling – a common issue in Denver where repeated freeze-thaw cycles fracture crown surfaces every two to three years. The chimney cap, flashing at the roof line, and visible mortar joints are all documented at this stage.
- Firebox and damper inspection. Inside the home, the technician examines the firebox floor and walls for cracked firebrick, deteriorating refractory panels, and any signs of water intrusion. The damper – the metal plate that controls draft above the firebox – is opened and closed manually to confirm it seals properly and moves without binding.
- Smoke chamber and smoke shelf inspection. Above the damper sits the smoke chamber, a tapered section that funnels combustion gases into the flue. The smoke shelf – a horizontal ledge behind the damper – collects debris, ash, and moisture. Both are inspected for parge coat integrity (the mortar coating on the chamber walls) and debris buildup.
- Flue liner visual inspection. The technician uses a high-powered light to visually inspect the flue liner from the firebox opening and, where accessible, from the top. Clay tile liners are checked for cracks, offset joints, and mortar deterioration. Any section that looks irregular gets flagged for camera confirmation – which, if ordered, becomes a Level 2 inspection.
- Photo documentation and written report. Every finding – from a minor creosote accumulation to a cracked crown joint – is photographed and included in your written report. This is Clause 4 of the Haven Standard: a documented photo record on every visit, included as standard. You receive the report the same day. It becomes your baseline for next year’s inspection.

AfterLevel 1 Inspection Pricing in Denver
A Level 1 chimney inspection in Denver typically runs $99 to $199 when booked as a standalone service. When combined with an Annual Sweep – which most Denver homeowners do, since you’re already in the flue – the inspection fee is often bundled into the sweep price.
| Service | Typical Denver Price Range |
|---|---|
| Level 1 Inspection (standalone) | $99 – $199 |
| Level 1 Inspection + Standard Chimney Sweep | $199 – $329 |
| Level 1 Inspection + Heavy Creosote (Class II/III) Sweep | $299 – $499 |
| Upgrade to Level 2 Camera Inspection (if flagged) | $99 – $149 additional |
A few things affect where your job lands in those ranges. Chimney height is the biggest factor – a two-story Denver Victorian in Curtis Park has significantly more linear flue footage than a ranch-style home in Sloan Lake. Access matters too: chimneys blocked by large trees or steep roof pitches take longer to inspect safely from the exterior. Creosote accumulation class affects the sweep portion – a Class III glaze requires Soot Removal and chemical treatment before a brush can be used, which adds time and materials.
What doesn’t change: the written price is on paper before we start. If the technician finds something that would push the total higher, they stop, explain it, and give you a new written price. You decide whether to proceed. No surprises added to the invoice after the truck is already in the driveway.

What Denver’s Climate Does to Chimneys
Denver averages around 300 days of sun per year, which sounds like good news for masonry. But the temperature swings are severe. A morning in January can start below 10°F and hit 50°F by early afternoon. That repeated thermal cycling – contraction overnight, expansion midday – works mortar joints apart faster than in cities with more moderate winters.
Water is the real problem. When moisture gets into a small crown crack in November, it freezes, expands the crack, thaws, and refreezes. By March, what was a hairline crack is often a visible gap that needs a crown rebuild. We see this in older neighborhoods like Berkeley, Park Hill, and Platt Park regularly. Homes built between the 1940s and 1970s with original clay tile liners are particularly vulnerable – the tile itself is sound, but the mortar between sections softens when wet and hardens brittle when dry, and eventually the joints separate.
Denver’s elevation – 5,280 feet – also affects draft. At altitude, air is less dense, which reduces natural draft in fireplaces. Homeowners sometimes compensate by burning hotter or longer fires, which accelerates creosote buildup and puts more thermal stress on liner joints. A Level 1 inspection catches the downstream effects of that before they become a liner replacement.
We use materials sourced through Haven’s buying network – including Gelco chimney caps and Olympia Chimney liner components – specifically because they’re rated for the temperature differentials Denver fireplaces actually see, not just the averages that look fine on a spec sheet.
What the Report Tells You
Some inspection reports are a checkbox on a form and a handshake. Ours aren’t. The written report from a Level Two Level 1 inspection includes:
- The condition of the crown, rated by visible cracking and surface integrity
- Cap and flashing status, including any rust, joint separation, or missing sections
- Mortar joint condition on the exterior masonry
- Damper operation and seal quality
- Smoke chamber parge coat condition and debris level
- Flue liner condition as far as visual inspection allows, with a clear recommendation if camera confirmation is warranted
- Creosote classification (Class I, II, or III) with a plain-language explanation of what each class means for your sweep schedule
- Timestamped photos of every area inspected – not just the problem spots
- A written scope and price for any recommended follow-up work
That report is yours. It’s the documentation a real estate attorney, a homeowner’s insurance underwriter, or a future buyer can read and understand. We’ve had Denver homeowners pull their 2017 inspection report out of a file folder to show a buyer in 2024. That’s what Clause 4 of the Haven Standard was designed to make possible.
Level 1 vs. Level 2: Which One Do You Actually Need?
Level 1 is the right starting point for most Denver homeowners. If the chimney is in regular use, hasn’t experienced a fire event, and you’re not changing the appliance or fuel type, a Level 1 inspection covers what NFPA 211 requires.
A Level 2 Inspection – which includes a camera scan of the full flue – is required when there’s been a chimney fire, when the property is changing hands, or when the technician finds something during a Level 1 that the visual check can’t resolve. If our technician sees a crack at the top of the accessible liner section that could extend further up, they’ll tell you plainly: “This needs a camera.” You’ll get a written price for the Level 2 before they proceed.
Level Two Chimney Co. takes its name from the NFPA 211 Level 2 camera standard – it’s the inspection we built the company around in 2009, years before it became a common request from insurers. But not every visit needs a camera. A Level 1 done thoroughly is a real inspection, not a lesser one.

FAQs – Level 1 Inspection in Denver
How much does a Level 1 chimney inspection cost in Denver?
A Level 1 chimney inspection in Denver costs between $99 and $199 as a standalone service. When bundled with a chimney sweep – the most common combination – the total typically runs $199 to $329 depending on chimney height, liner length, and creosote accumulation level. The written price is on paper before any work starts. Call (720) 674-7312 for an exact quote – it takes about two minutes and there’s no obligation.
How long does a Level 1 inspection take?
A Level 1 inspection at a standard Denver single-family home takes 45 to 60 minutes from arrival to written report. Homes with taller chimneys, multiple flues, or significant creosote buildup run closer to 75 minutes. We don’t rush the documentation – the photo record and written findings are the point of the visit, not an afterthought.
Do I need a chimney inspection every year if I only use the fireplace a few times a season?
Yes. NFPA 211 calls for an annual inspection on any chimney in use, regardless of frequency. Infrequent use doesn’t protect the masonry from freeze-thaw damage or cap deterioration, and even occasional wood fires produce enough creosote in the right temperature conditions to warrant a visual check. Denver’s elevation and temperature swings are hard on clay tile liners whether you’re burning every night or twice a year.
Can I schedule a Level 1 inspection and sweep on the same visit?
Yes, and most Denver homeowners do. The inspection happens first – we look before we sweep, every time. If the sweep is straightforward (Class I creosote, accessible flue, standard height), the technician can complete it the same visit. If something comes back in the inspection that changes the scope – a Class III creosote deposit, a cracked damper plate, a blocked cap – you’ll get a written price for the adjusted work before anything proceeds. Call (720) 674-7312 to book both in one appointment.
