This isn’t a generic sweep-and-go service. Chimney Inspection in Boulder means checking for cross-contamination between shared flues, documenting creosote at 5,430 feet, and verifying that a chinook wind event won’t push a neighbor’s exhaust into your house. Ruben Castellano leads our team, and he’s built Alcott Chimney Sweep around one idea: show the homeowner exactly what the camera sees, then put the price in writing before anything gets touched.

We serve Boulder from our Denver metro dispatch office, and crews are in Boulder neighborhoods daily. You’ll know your technician’s name and see their photo before the truck pulls up. No surprises, no strangers.

Why Alcott Chimney Sweep Is Boulder’s Preferred Chimney Inspection Company

Boulder Chimney Sweep has been serving Colorado homeowners since 2002 as part of the Threshold Group family. Every technician who steps onto a Boulder property passes a background check and identity verification before dispatch. That’s the Threshold Standard, and it’s not an optional upgrade. You get a uniformed professional whose name and photo arrive on your phone before the visit, and who is required to show a photo ID badge at your door. Every time. No exceptions.

Boulder homeowners deal with a specific set of chimney problems: shared masonry stacks in dense older neighborhoods, downslope winds off the Flatirons that reverse draft direction, and rapid creosote accumulation from high-altitude combustion. A company that only sweeps flues will miss the cracked clay tile or the backdrafting neighbor’s insert. We document all of it, with camera footage you can watch yourself.

Every job includes a written price before work begins and a written guarantee on every repair. Our 365-Day Done Right Promise means if the work isn’t right within a year, we return and make it right, free. That’s a full year of accountability, in writing, on every job. Ruben Castellano doesn’t sell vague promises. He sells certainty.

Chimney Camera Inspection in Boulder

Chimney camera inspection in Boulder is the only way to see what’s actually happening inside a flue when the exterior brick looks fine from the street. We snake a high-resolution camera through the flue liner from top to bottom, capturing every joint, every crack, and every creosote deposit. In Boulder, where homes on Mapleton Hill routinely have century-old clay tiles and 1950s ranches have EPA inserts crammed into oversized flues, a camera inspection catches what a flashlight and mirror cannot.

What Our Camera Shows You

You don’t take our word for it. We show you the footage. Cracked flue tiles, deteriorating mortar, animal nesting material, second-degree creosote in the smoke chamber, a shared flue that was never properly separated from a neighbor’s. You see the exact problem, and you get a written price to fix it only if it needs fixing. Nothing gets recommended without camera evidence you can watch yourself.

When Boulder Homes Need a Level 2 Camera Inspection

A Level 2 inspection is the right call before buying or selling a home in Boulder, after a chimney fire, after an earthquake or severe windstorm, or when you’re changing fuel types. Boulder County no-burn days under the CDPHE air quality program mean wood-burning households get a restricted window of legal burning days, and you can’t afford to discover a failing liner in November. Most Level 2 inspections in Boulder run $285 – $485, and the written report is accepted by home insurers.

Fireplace Inspection in Boulder

Fireplace inspection in Boulder focuses on the firebox, damper, and the first several feet of flue where the hottest gases hit the masonry. We’re looking for cracked refractory panels, rusted or warped dampers, and the shallow, hardened creosote glaze that forms faster at 5,430 feet than it does in Denver or Fort Collins. A fireplace that burns fine in September can backdraft in January when a chinook wind slams the Flatirons and reverses pressure in your chimney.

What We Check in Wood-Burning Fireplaces

We inspect the firebox walls for spalling brick, the hearth extension for code clearance, and the damper for a full seal. In Boulder’s older homes, we also check the smoke shelf and throat for creosote bridging, which is exactly the deposit that ignites in a chimney fire. If you’ve had smoke puffing back into the room on windy days, that’s a draft reversal, not a design flaw, and it has specific fixes.

Gas Fireplace Inspection Notes

Gas inserts and gas log sets vent differently than wood fires, and they have their own failure modes. We check the venting configuration, the condition of the existing masonry flue around the liner, and whether combustion air is being pulled from the right place. In Boulder duplexes and attached homes, we pay particular attention to whether multiple gas appliances share an improperly sized or separated stack.

Common Chimney Inspection Problems We See in Boulder Homes

• Shared flues in attached properties. Boulder’s dense housing stock, especially on Mapleton Hill and in the downtown historic districts, often shares a masonry stack between adjacent units. If a neighbor’s appliance vents into the same stack without proper separation, their exhaust can push backward into your clean flue. We document this with camera footage and isolate the flue with a DuraFlex liner when needed.
• Chinook downdrafts off the Flatirons. The downslope winds Boulder gets can hit 60 – 80 mph in winter, creating negative pressure that pulls smoke and creosote odors back into living spaces. This is often misdiagnosed as a simple draft problem. The fix is usually a correctly sized cap and, in some cases, a draft-inducing setup, not a full rebuild.
• Accelerated creosote at elevation. Wood combustion at 5,430 feet produces less complete burning, which means first- to second-degree creosote forms in fewer burns than it would at sea level. A chimney that was “just cleaned” in Denver might already be glazing over in Boulder. We see this constantly in Chautauqua and Knollwood homes that burn regularly through the winter.
• Retrofitted inserts in oversized flues. A large share of Boulder’s 1950s – 1970s ranch and split-level homes have EPA-certified wood stove inserts venting into original masonry flues sized for open fireplaces. The smaller exhaust stream cannot properly heat the large flue cavity, which creates creosote pocketing and liner sizing problems. Inspection is about measuring that mismatch, not just looking at it.

Trusted Brands We Service in Boulder

Our Boulder crews carry and install professional trade materials, not box-store substitutes. That means DuraFlex liner systems when we need to isolate a shared flue on Mapleton Hill, HeatShield resurfacing when a century-old clay liner is cracked but the masonry is still sound, and Gelco, Olympia, Famco, and Copperfield components for caps, dampers, and venting. When you see the brand name, you can look it up. These are the materials chimney professionals specify. We keep common Boulder parts stocked locally through our Denver dispatch, so a follow-up cap or damper replacement usually happens within days, not weeks.
