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.

Call (720) 439-4666 - a live person answers, 24 hours a day.
We’ve been camera-scanning chimneys in Jefferson County since 2009, and Columbine’s housing stock is unlike anything east of the metro. These are original tract homes with masonry fireplaces now 40-60 years old, most venting gas appliances into flues never designed for them, sitting directly in the path of chinook winds that blow down through the mountain breaks. That combination creates failure modes you won’t find in Aurora or Commerce City. Our Chimney Repair team knows what to look for because we’ve documented it on thousands of inspections.
Why Level Two Chimney Littleton Is Columbine’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections since 2009, and a significant share of those have been in Columbine and the surrounding Jefferson County foothill communities. Homeowners here don’t need a sales pitch. They need someone who will show them what the camera found, name a written price before any work starts, and leave them with documented photo evidence under Haven Standard Clause 4.
Our reviews from Columbine customers consistently mention the same things: the tech arrived on time and sent a text when en route, the camera footage was displayed on a monitor in real time, and the written quote matched the final invoice. That’s not accidental. It’s Clause 1 of the Haven Standard - written price, written scope, written warranty before anyone picks up a tool.
Dispatch and scheduling are coordinated from our Denver office, but crews serving Columbine live and work locally. They know the difference between a 1968 ranch off Coal Mine Avenue and a 1979 split-level near Wadsworth Boulevard, and they know both were built with clay-tile flue liners that have endured four decades of freeze-thaw cycling at 5,400-5,600 feet.
Every technician is background-checked, uniformed, and arrives with a license number displayed. The 365-Day Done Right Promise applies to every repair we perform in Columbine: if it’s not done right, we make it right.
Our Chimney Repair Services in Columbine
Mortar Repointing
The mortar joints in Columbine’s original masonry chimneys have been through 40-60 years of thermal cycling at foothill elevation, and it shows. We grind out deteriorated mortar to proper depth and repoint with color-matched, high-lime mortar formulated for Colorado’s freeze-thaw conditions. On a typical Columbine ranch near Bowles, we recently repointed 18 linear feet of crown-to-roofline mortar where chinook-driven water infiltration had eroded the bedding to sand. The homeowner received before/after photos and a written 10-year warranty on the mortar work.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - accelerates at Columbine’s elevation where nighttime temperatures drop sharply even after warm days, driving moisture deeper into the masonry freeze-thaw cycle. We remove spalled brick courses, match replacement brick for color and hardness, and rebuild with proper weep details. Our techs regularly find spalling concentrated on the south and west faces of Columbine chimneys, the ones that take the brunt of afternoon sun followed by rapid evening cooling.
Chimney Waterproofing
Columbine’s position against the foothills means more snow loading on crowns and more wind-driven rain against chimney shoulders than lower-lying Denver neighborhoods see. We apply vapor-permeable waterproofing sealers that let the masonry breathe while blocking liquid water intrusion. This is critical on 1970s chimneys where the original crown was poured without proper overhang or drip edge, a common construction shortcut we document on camera before recommending any treatment.
Flashing Repair
Step flashing and counterflashing around chimney penetrations fail predictably in Columbine after decades of snow load and thermal movement. We fabricate custom flashing from heavy-gauge material and seal with high-temperature polyurethane, not the roofing cement some crews slap on. In the Columbine Knolls area and similar neighborhoods, we’ve found original flashing that was never properly integrated with the roof underlayment, creating leak paths that rot roof decking before homeowners ever notice water inside.
Chimney Rebuilding
When deterioration exceeds what localized repair can address, we rebuild from the roofline up or perform full-stack reconstruction, always with a written scope and price before work begins. Rebuilds in Columbine typically involve replacing deteriorated clay-tile liners with properly sized stainless systems, pouring new crowns with proper slope and overhang, and ensuring the rebuilt stack can handle whatever appliances currently vent through it.
Tuckpointing
Precision tuckpointing restores both structural integrity and appearance on chimneys where mortar loss is advanced but the brick itself remains sound. We match existing joint profiles and use lime-based mortars compatible with vintage masonry, critical on Columbine homes where harder Portland-based repointing would accelerate brick damage.

AfterTrusted Brands We Service in Columbine
We source repair materials through Haven’s buying network to keep customer prices honest, stocking DuraFlex stainless liner systems, HeatShield cerfractory flue resurfacing products, and Olympia Chimney caps and components for fast turnaround on Columbine jobs. When a 1970s clay liner needs sectional replacement or a new cap with spark arrestor is required for wildland-urban interface compliance, we’re not waiting on special orders. Gelco cap assemblies are also available for custom-fit installations on non-standard flue dimensions common in Columbine’s vintage housing stock.
Common Chimney Repair Problems We See in Columbine Homes
- Orphaned gas appliances in fireplace flues. Most original Columbine masonry chimneys now vent furnaces or water heaters into flues sized only for fireplace draft. Our camera finds this in nearly every house, and chinook backdraft pressure can reverse airflow in these undersized passages, pushing combustion gases back into living spaces.
- Cracked clay-tile liners after decades of freeze-thaw. At 5,400-5,600 feet, Columbine’s temperature swings are sharper than Denver’s. Clay tiles spall and crack, but homeowners are routinely quoted full relines by companies that never ran a camera to prove the damage exists.
- Missing rain caps and spark arrestors. Original 1960s-70s construction often omitted these entirely. Water wicks into crowns and mortar year-round, and uncapped flues can emit embers during dry chinook conditions - a genuine fire risk with wildland interface only miles up the hogback.
- Crown deterioration from snow load and poor original construction. Crowns poured without proper slope, overhang, or reinforcement crack and allow water directly into the chimney core. We see this on the majority of un-repaired Columbine chimneys over 40 years old.

FAQs - Chimney Repair in Columbine
Chinook downslope winds create negative pressure on your roof that can overcome normal chimney draft, especially in older flues with marginal capacity. This is far more common in Columbine than in flatter eastern suburbs because the foothill breaks funnel high-velocity wind directly across these neighborhoods. A properly sized liner, functional damper, and secure cap help, but the first step is a camera inspection to rule out blockages or liner damage that make the problem worse. Call (720) 439-4666 to book a scan - estimates are free.
Yes, and it’s one of the most common hazards we camera-document in Columbine’s original tract housing. The flue was sized for fireplace draft, not the continuous lower-temperature exhaust of a gas appliance, and chinook backdraft pressure can reverse airflow in these undersized passages. Carbon monoxide and moisture-laden exhaust spill back into utility closets and living spaces. We evaluate the flue capacity with camera and draft testing, then specify either a dedicated vent or a properly sized liner section - never a full reline unless the footage proves it’s necessary. Call for a written scope and price.
Yes. Even inactive flues collect water that destroys mortar and liner from the inside, and Columbine’s heavier snow loading and wind-driven rain make uncapped chimneys deteriorate faster than in lower-lying areas. More critically, Jefferson County’s wildland-urban interface regulations and basic fire safety require spark arrestors on any flue that could conceivably vent combustion - including gas appliances. We install Gelco and Olympia Chimney caps with proper screening for $250-$650, written price before work starts.
Demand to see the camera footage. On a 1974 ranch off Coal Mine Avenue near the hogback, we pulled the firebox damper and ran a camera up a clay-tile flue that a previous company had quoted a full reline on without ever showing the homeowner the footage. The scan revealed the liner was intact - the real failure was a rusted-out thimble where the gas water heater tied into the stack, letting flue gases spill back into the utility closet under chinook backdraft. We rebuilt the thimble connection with a properly sized DuraFlex liner section, repointed two spalling brick courses at the crown, and showed the homeowner the before/after camera run on our monitor. Clause 4 of the Haven Standard requires a photo record on every job specifically to prevent this scenario. If another company won’t show you footage, call us for a free second opinion.
Crown sealing or rebuilding, mortar repointing at the roofline, and proper cap installation top the list. The 40-60 year old clay-tile liners are often intact but improperly sized for current appliances, requiring thimble modification or sectional liner work rather than full replacement. Flashing repair is also common where original installations failed to integrate with roof underlayment. We prioritize these based on what the camera shows, not a standard package. Call (720) 439-4666 for a written estimate - we’ll tell you what can wait and what can’t.
