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.

AfterChimney Company in Boulder, CO
Boulder’s chimney work runs on two clocks: winter burn season and the spring thaw that follows it. Homes here sit anywhere from 5,300 feet up to 6,500 feet against the foothills, and that elevation changes how a chimney drafts, how creosote builds, and how quickly a flue glazes over. We’re Flint Chimney Sweep, and we work to one rule on every job in Boulder: a written price before the tools come off the truck. The number on the invoice is the number you approved. Call (830) 251-4560 and you’ll get a live person, not a voicemail tree.
Why Boulder Homes Are Different
Boulder’s housing stock isn’t one thing. The Mapleton Hill and Whittier neighborhoods near downtown are full of Victorians and Craftsman-era homes, many of them with original masonry that’s now 90 to 120 years old. Those older flues were built for open-hearth fires, not the high-efficiency inserts and stoves people install now, and the mismatch shows up as draft problems and cracked clay tiles on the flue’s inner liner. The newer subdivisions out toward Gunbarrel, South Boulder, and the Table Mesa area tend to be prefabricated fireplace systems, which have their own wear pattern: warped firebox panels, failed refractory joints, and water entry at the chase top.
The climate does the rest of the work. Freeze-thaw cycles in the Colorado Front Range are relentless. Water seeps into a brick crown’s tiny cracks during the day, freezes at night, and the expansion breaks off chips of masonry a little more each season. That same cycle explains why chimney crowns and mortar joints in Boulder degrade faster than homeowners expect. Add the spring chinook winds that barrel down against the Flatirons, and you have real wind-driven rain pushing against chimney caps and flashing. None of that is theoretical; we see it on almost every older home we inspect in the area.
Our Main Boulder Services
Most calls we get in Boulder start with one of three things: a chimney that hasn’t been swept in years, a home purchase that needs an inspection, or a problem someone spotted during burning season. Here’s how each one works with us.
Chimney Sweep in Boulder
A Chimney Sweep in Boulder with us means the flue gets brushed from top to bottom, the firebox is vacuumed out, and the technician checks the damper for proper operation before he leaves. Homes in Boulder that burn pine or fir from Front Range suppliers tend to build up a faster layer of creosote because the resin content is higher than hardwoods, which is why we recommend an annual sweep if you burn more than two cords per season. The technician also confirms the cap and roof flashing are seated correctly while he’s up top, because wind here loosens both. The price you’re quoted covers all of it, and nothing gets added at the door.
Chimney Inspection in Boulder
A Chimney Inspection in Boulder is the one service we tell every buyer to schedule before closing. Real estate transactions in Boulder move fast, and sellers often can’t tell you when the chimney was last looked at. Our inspection includes a camera run up the flue so you can see the condition of the liner for yourself, not just hear a summary. In older Boulder homes, the camera frequently shows cracked clay tile liners or missing mortar joints that a visual check from the rooftop would miss. We hand you a written report with photos, and we don’t recommend repairs that the camera doesn’t document.
Chimney Repair in Boulder
Chimney repair work in Boulder breaks down into two main groups: water damage and liner failure. The wet-dry environment along the Front Range accelerates both. Chimney Repair in Boulder covers crown rebuilding, tuckpointing, flashing replacement, flue relining (replacing the inner liner that channels smoke safely out of the house), and firebox rebuilds. Every repair we quote gets a written price before work starts, and every repair carries the 365-Day Done Right Promise: a written guarantee valid for one full year, with a no-charge return visit if a covered repair fails in that window.

FAQs About Chimney Company in Boulder
Our typical scheduling window in Boulder is 2 to 5 business days. Chimney sweeps and inspections take one visit. Repairs may need a second visit if parts have to be ordered, and we’ll tell you that before the first appointment ends. Written pricing comes before any work starts on either visit.
Most chimney maintenance including sweeps, inspections, caps, crowns, and liner replacement falls under routine home upkeep and doesn’t require a city permit. If a repair crosses into structural masonry work, Boulder’s building department may need to be involved. We’ll flag that in the quote so there are no surprises with your HOA or the city.
Freeze-thaw cycles are the main driver. Boulder’s elevation means more days hovering near freezing, and that repeated expansion and contraction cracks masonry crowns and mortar faster than in consistently colder or warmer climates. Add the spring winds against the foothills and you have real moisture forcing its way in.
We answer the phone 24/7 and every call goes to a live person. If you’re in Boulder and want a real number in writing before work begins, call (830) 251-4560 for a free estimate. No voicemail, no callback form. That’s the way we’ve run it since 2002 as part of the Garrison Partners family.
