Frequently Asked Questions

We set up floor protection, run a rotary brush and vacuum system up the flue to remove creosote and debris, then lower a camera for the Level 2 inspection. The camera shows us flue tile condition, joint gaps, and any obstructions in real time. You see what we see. The whole process takes 60-90 minutes for a standard fireplace in Littleton, longer for complex systems or if we need to access the roof for exterior cap evaluation. Afterward, you get a written report with photos and any recommendations ranked by urgency.

The NFPA 211 standard calls for annual inspection, with cleaning frequency determined by what the inspection finds. In practice, most Littleton homeowners who burn regularly - say, three or more times weekly through the season - need annual cleaning. Occasional users might go two years if the Level 2 inspection shows minimal buildup. The Front Range's dry climate and temperature swings do create thermal stress on masonry, so we inspect for structural issues yearly even when cleaning isn't required. Homes at higher elevation in Ken Caryl or Golden often see faster creosote accumulation due to cooler flue temperatures.

Plan on 60-90 minutes for a single fireplace system in typical condition. A second flue, a wood stove insert with a liner, or significant creosote glazing can extend that to two hours. We schedule real windows, not four-hour blocks - Clause 2 of the Haven Standard - and text when the technician is en route. In spread-out areas like Parker or the south end of Highlands Ranch, we build drive time into the window so we're not rushing your job or the next one.

Clear a three-foot workspace around the fireplace and remove any fragile items from the mantel. Don't burn a fire for 24 hours beforehand - the flue needs to be cool for safe cleaning and accurate camera readings. We bring our own drop cloths, vacuums, and tools. If you have questions about the system, jot them down; our technicians are trained to explain what they find using the actual camera footage, not jargon. Access to the roof is helpful but not required - we can evaluate most exterior components from ground level or ladder.

We inspect first, clean second, and we'll tell you honestly if the system is safe to use before we finish. Heavy creosote buildup - Stage 3 glazing, in trade terms - requires more aggressive cleaning methods and takes longer, but it's manageable. What concerns us more: undetected damage from years of thermal cycling, which is common in Littleton's freeze-thaw climate. The camera finds it. We've opened up flues in Englewood and Wheat Ridge that hadn't seen a sweep in a decade; the cleaning was straightforward, but the inspection revealed deferred maintenance that needed addressing. You'll know either way before we pack up.

For stainless steel relining, we typically work with Olympia Chimney and Famco products, both of which carry appropriate UL listings for solid fuel and gas applications. The specific recommendation depends on your appliance type, flue diameter, and whether we're lining for a fireplace, wood stove, or gas insert. In Littleton's older homes near Belleview and Broadway, we've found Olympia's flexible liners handle the offset flues common in 1960s construction particularly well. We don't source from brands we can't document - every product spec goes in your written report.

Every professional working under the Level Two Chimney name is required to hold the license and insurance their state requires, and we verify that status before anyone enters a home. Colorado does not mandate a specific chimney sweep license, so we look for CSIA certification or equivalent trade credentials, plus general liability coverage. The technician's license information is available on request, and our general liability and workers compensation policies protect your property while we're on site. This is Clause 3 of the Haven Standard: verified crews, documented and current.

The local business carries appropriate bonding for the contracting work we perform, including liner installation and masonry repair. Routine inspections and cleanings don't typically require a bond, but we maintain coverage that supports the full scope of services we offer. If you have specific requirements from your HOA - common in gated communities in Highlands Ranch or Ken Caryl - we can provide a certificate of insurance naming them as additional insured. Just let the coordinator know when you book.

The industry standard is CSIA (Chimney Safety Institute of America) certification, which requires passing a comprehensive exam and continuing education. NFI (National Fireplace Institute) certification is also respected, particularly for gas appliance work. We require one or the other for technicians conducting Level 2 inspections. Certifications matter because they demonstrate tested knowledge of NFPA 211, clearances, and venting science - not just brush technique. When you call (720) 439-4666, you're welcome to ask which certifications your scheduled technician holds.

We're open Monday through Friday, 7:30 AM to 7:30 PM, and Saturday and Sunday, 8:00 AM to 6:30 PM. Calls during those hours are answered by a live coordinator who connects you with the local team - not an overseas queue, not an automated maze. For chimney concerns outside those hours, use your judgment: active chimney fire or suspected carbon monoxide intrusion warrants 911. A strong smoke smell or minor draft issue can typically wait until morning. We return next-business-day calls in the order received, with priority for safety-related descriptions.

A chimney fire - loud cracking or popping, dense smoke, or visible flames from the top - is an emergency requiring immediate evacuation and 911. Suspected carbon monoxide symptoms (headache, nausea, confusion) with any fuel-burning appliance also demand emergency response. Everything else is urgent but not emergent: a stuck damper, water leaking into the firebox, animal noises in the flue, or smoke backing up into the room. For those, call us during hours and we'll get you scheduled. In Littleton's older neighborhoods with original masonry, we've seen water intrusion after heavy spring snows; it's damaging over time but doesn't require midnight dispatch.

Same-day availability varies by season and existing bookings. Early October through Thanksgiving is peak demand across the Denver metro, and we often book 3-5 days out during that window. Late spring and summer typically have more flexibility. We don't promise dispatch times we can't keep - Clause 2 of the Haven Standard is about real windows, not wishful thinking. If your situation has safety implications, we'll do our best to bump you up, and we'll tell you honestly what the schedule looks like when you call.

The Littleton branch covers the southwest Denver metro, including Columbine, Englewood, Highlands Ranch, Ken Caryl, Greenwood Village, Centennial, Lakewood, Wheat Ridge, Denver proper, Parker, and Golden. Drive time and scheduling logistics mean we may book certain outer areas on specific days - Parker and Golden, for instance, often share a route - but we don't decline work based on zip code. Every job gets the same Level 2 inspection protocol and written documentation, whether it's a condo near Littleton Boulevard or a hillside home in Ken Caryl Valley.

The cleaning itself is warranted against workmanship defects - if we leave debris that obstructs draft, or if a tool damages your firebox, we return and fix it at no charge. The inspection findings are documented with photos and written description, creating a record you can reference. For repairs and installations, warranties vary by product and scope: stainless steel liners typically carry a lifetime manufacturer warranty when properly maintained, while masonry repairs are warranted against workmanship failure for a specified period. Every warranty term is written into your estimate before work begins - Clause 1 again - so there's no ambiguity about what's covered and for how long.

The Haven Standard is a five-clause service agreement that governs every job we perform. Clause 1: flat price, written scope, written warranty before work starts. Clause 2: scheduled arrival with named technician and en-route text. Clause 3: verified, documented licensing and insurance for every crew member. Clause 4: photo and video evidence of what we found, archived for your future reference. Clause 5: no surprises - no additional charges without your written approval, no pressure to expand the scope. It was built from Level Two Chimney's practice of archiving camera footage years before the industry required it, and it's what distinguishes a documented inspection from a flashlight glance.

Tell us specifically what fell short, and we'll address it. That might mean returning to re-clean a section, re-inspecting an area you have questions about, or walking through the photo report with you again until you understand what we found and why we noted it. We don't offer vague "satisfaction guarantees" that dissolve into he-said-she-said; we offer specific documentation and specific recourse. If we missed something in the initial scope, we own it. If you simply disagree with a recommendation, we'll show you the evidence again and explain our reasoning. You decide what to do with it.

We don't guarantee response times we can't control. What we do guarantee: when you report a concern, a live coordinator logs it, a technician reviews your archived job record, and we call you back with a plan within our operating hours. For genuine workmanship failures - a cap that blows off in high wind, a liner joint that separates - we prioritize repair scheduling and don't charge for the callback. For issues that turn out to be unrelated to our work, we'll show you the documentation and quote any new work at standard rates. The written record protects both of us.

We rank every finding by urgency in your written report: Monitor (no action needed, check next year), Schedule (plan for within the season), and Address Before Use (unsafe to operate as-is). A cracked crown in Littleton's climate might be "Schedule" - water intrusion will worsen it, but it's not an immediate hazard. A displaced flue tile with visible gaps is "Address Before Use" - carbon monoxide can leak into living space. We show you the camera footage for both, explain the mechanism of failure, and let you decide your timeline. No scare tactics. The photos speak for themselves.
