Denver’s brick chimneys need service every 1–2 years, but older homes with heavy use or wood-burning fireplaces should schedule twice yearly. Start with a DIY inspection for creosote buildup and cracks, then call a pro when you spot warning signs like smoke backflow or rusted dampers. Never attempt liner repairs or major masonry work yourself; these void warranties and risk carbon monoxide leaks. For a tailored schedule, book a chimney inspection with Maroon Chimney LLC before winter sets in.
Denver’s Chimney Service Schedule: Brick Homes Need More Attention
Older brick chimneys in Denver, especially those built before the 1980s, require stricter maintenance than modern systems. If your home has a masonry chimney with a clay liner (common in pre-1990s builds), schedule a professional chimney sweep every 1–2 years, or annually if you burn wood regularly. Gas fireplaces still need inspections every 2 years, but Denver’s dry winters and high-elevation winds can accelerate wear. Start your schedule in early fall: book a sweep before your first fire of the season to catch hidden issues. For homes in Lakewood or Wheat Ridge with older brickwork, add a mid-winter check if you notice drafts or soot around the fireplace.

3 Quick Brick & Liner Checks for Pre-1980s Denver Homes Before You Call Us
Between professional visits, perform these three quick checks to spot trouble early. First, inspect the damper: Open it fully and shine a flashlight up the flue. If you see thick, glossy black creosote (like tar), schedule a chimney sweep. Next, check the fireplace opening for cracks in the brick or mortar, use a screwdriver to probe gently. Small hairline cracks are normal, but gaps wider than a pencil lead mean moisture is seeping in, which weakens masonry over time. Finally, test for drafts by lighting a match near the damper when the fireplace is cold. A strong pull means good airflow; no pull or smoke spilling into the room signals a blockage. Learn more DIY tips before attempting any work.
Warning Signs: When Your Chimney Says ‘Call a Pro Immediately’
If you notice any of these during your DIY checks, stop using the fireplace and contact Maroon Chimney LLC right away. Rust on the damper or smoke backflowing into the room mean your chimney liner is failing, this is a fire and carbon monoxide risk. Cracks larger than 3/8 inch in the masonry or missing mortar joints require professional repointing to prevent water damage. Denver’s freeze-thaw cycles worsen these issues, so don’t wait until winter to act. Another red flag: a strong odor of gas or wet wood when lighting the fire, which could indicate a cracked heat exchanger in gas systems or a blocked flue. See our guide on common chimney problems for visual examples of these issues.
Why DIY Chimney Work on Your 1920s Sloane Street Home Could Backfire (And What to Avoid)
Attempting these tasks yourself risks injury, voids warranties, and can make problems worse. Never climb onto your roof to inspect or clean the chimney cap. Denver’s brick chimneys are heavy, and falls from 20+ feet are common. Avoid using wire brushes or chemical cleaners inside the flue; these damage liners and create toxic fumes. If your chimney has a stainless steel liner (common in newer builds or retrofits), never attempt to bend or install it yourself, poor fits cause leaks and carbon monoxide poisoning. Masonry repairs like repointing or tuckpointing require specialized mortar and tools; DIY jobs often fail within a year due to Denver’s moisture swings. Compare DIY vs. pro cleaning to see why professionals use rotary brushes and video inspections.

Frequently Asked Questions
How much does a chimney sweep cost in Denver, and does my older brick home need more?
In Denver, a basic chimney sweep for a brick masonry chimney costs $120–$250, depending on height and creosote level. Older brick homes with clay liners often need extra inspections ($80–$120) to check for cracks or liner deterioration. If your chimney hasn’t been serviced in over 2 years, budget $200–$400 for a full cleaning and inspection. See our pricing guide for breakdowns by service type, or request a quote for a site-specific estimate, we’ll factor in your home’s age and brickwork condition.
My Denver home has a wood-burning fireplace. Should I sweep more often than neighbors with gas fireplaces?
Yes. Wood-burning fireplaces in Denver produce 10x more creosote than gas models, so schedule a sweep every 1–2 years, or annually if you burn cordwood. Denver’s dry air and high-elevation winds also speed up creosote buildup. If you burn untreated wood or resinous species like pine, creosote accumulates faster. Compare wood vs. gas fireplaces to see how your fuel choice affects maintenance costs. Pro tip: Burn only seasoned hardwood (moisture <20%) to reduce soot.
I found cracks in the brickwork near my fireplace. Can I fix them myself, or should I call a chimney sweep in Denver?
Small hairline cracks (thinner than a pencil lead) are often harmless, but any gap wider than 3/8 inch needs professional repointing. DIY mortar repairs in Denver’s freeze-thaw cycles rarely last more than a season. If the cracks are near the flue or accompanied by soot stains, moisture is seeping in, this weakens the masonry and can lead to spalling (brick flaking). See our chimney repair guide for photos of fixable vs. critical damage. For safety, contact us before attempting repairs; we’ll assess whether repointing or a full masonry restoration is needed.
