For Englewood’s older brick homes, especially those with cracked mortar or no flue liner, schedule a sweep between August and October, before your first fire of the season. These homes need two cleanings a year, in spring and fall, to stop creosote buildup and freeze-thaw damage from Englewood’s winters. Don’t wait until you spot soot on your ceiling.
What does a chimney sweep actually do, and why does the timing matter for homes along Englewood’s brick-lined streets?
A chimney sweep is a deep clean of your flue, smoke chamber, and fireplace interior, clearing out soot, creosote, and any loose debris blocking airflow. In Englewood, where many homes have original brick chimneys built in the 1950s–1970s, timing is critical because: - Creosote hardens faster in Englewood’s dry winters, turning flammable. - Mortar cracks from freeze-thaw cycles let moisture seep into brick, weakening the structure. - Wood-burning bans (like those in nearby Cherry Hills Village) can trap unburned fuel in your flue if you haven’t swept.
The Chimney Safety Institute of America CSIA recommends sweeping before the first fire of the season, typically September to October in Englewood, to catch buildup early. If your home uses the fireplace year-round (e.g., for supplemental heat in spring/fall), a second sweep in late winter is wise.
Why older brick chimneys in Englewood need sweeps more often than modern homes
Englewood’s older brick chimneys, especially those without liners, are prone to three hidden risks that make timing critical: 1. Creosote buildup: Unlined flues in pre-1980s homes accumulate Stage 2 (tar-like) creosote faster due to poor draft control. This is highly flammable and can ignite without warning, even during low-heat burns. Last winter in Englewood, three chimney fires started because homeowners skipped their sweeps. Neglect turns a small problem into a dangerous one. 2. Mortar deterioration: Englewood’s 100+ days of freeze-thaw cycles annually Englewood, CO erode mortar joints, letting rainwater seep into brick. A damp flue accelerates rust in metal components (like dampers) and promotes mold growth, both fire hazards. 3. Animal nests: Swifts and sparrows often nest in cracked brickwork or loose mortar. Their nests block airflow, forcing smoke into your home. Last spring, we removed a family of swifts from a chimney on South Broadway that had gone unswept for two years.
Solution: Schedule a pre-fall sweep (August–September) and a post-winter inspection (March–April) if you burn wood year-round. Older brick chimneys often need annual repointing /masonry-repairs-repointing-englewood-how-fix-crumbling-chimn/ to prevent moisture damage between sweeps. For the specifics, see everything we handle.
What risks do you take if you miss the ideal time to sweep your Englewood chimney, especially in a home with original brickwork?
Waiting until after your first fire, or worse, ignoring sweeps entirely, leads to three costly scenarios we see in Englewood: - Chimney fires: Creosote fires can destroy flue liners (costing $1,200–$3,500 to replace) and damage smoke chambers in brick. The NFPA National Fire Protection Association (NFPA))) reports 25,000 chimney fires yearly, half from neglected sweeps. - Carbon monoxide poisoning: Blocked flues force CO into living spaces. Englewood’s older homes with single-story layouts (like those near the Englewood Mall area) are at higher risk because bedrooms are closer to fireplaces. - Structural damage: Water from unrepaired leaks (common in Englewood’s clay tile roofs) seeps into brick, causing spalling (flaking) and efflorescence (white salt deposits). This weakens the chimney’s load-bearing capacity, a major issue for homes near I-70, where wind exacerbates wear.
Pro tip: If you’ve noticed white residue on your fireplace hearth or a strong, acrid smell when lighting fires, your chimney is already past due for a sweep. /blog/7-critical-signs-englewood-chimney-needs-pro-chimney-sweep-l/ details how to spot these early. More on this in contact the office.
How can you ready your Englewood home’s fireplace for a professional sweep without causing damage to your brick or liner?
A smooth sweep starts with three simple steps, especially important for older brick homes with ornamental brickwork or tight clearances (like those near Southgate Park): 1. Move everything back: Keep furniture, rugs, and decor at least 10 feet away from the fireplace opening before the sweep arrives. Soot and debris can scatter during cleaning. 2. Remove screens/glass doors: These trap creosote and make access difficult. If your fireplace has a tempered glass door, prop it open or remove it temporarily. 3. Check for pets/kids: Keep animals and children inside another room during the sweep. Our crews use HEPA vacuums, but fine dust can still irritate lungs.
What we’ll do: For Englewood’s older brick chimneys, we: - Inspect mortar joints for cracks (a sign of water damage). - Test draft pressure to ensure proper airflow. - Use rotary brushes for creosote removal (safer than scraping for brick). - Check for rust on dampers or corrosion in metal components.
Cost note: A standard sweep in Englewood runs $120–$250, but older brick chimneys with liners or complex masonry may cost $300–$500 due to labor time. /pricing/ breaks down pricing by chimney type. Full details in the team behind the work.
Is it safe to light a fire right after your Englewood chimney sweep, or should you wait?
Yes, but only after these three checks are complete: 1. Dry the flue: Moisture from cleaning can linger. Wait 24 hours before burning, especially in Englewood’s humid springs or dry winters. 2. Burn small, hot fires first: Start with dry, seasoned hardwood (oak or maple) and avoid softwoods (pine, fir) for the first few fires. This prevents new creosote buildup from unburned sap. 3. Monitor smoke flow: If smoke backflows into the room, your damper may be stuck or the flue isn’t fully clear. Never force a fire, this can push creosote into the flue, increasing fire risk.
Englewood-specific tip: If your home has a wood-burning stove, the EPA’s Burn Wise program EPA’s Burn Wise program recommends burning only when the fire is hot enough to melt ash, typically 300°F or higher. This reduces creosote formation between sweeps. Take a look at the neighborhoods we visit page.
What to do if your Englewood chimney sweep reveals damage
During a sweep, we often find hidden issues in Englewood’s older brick chimneys. Here’s what each problem means and how to fix it: - Creosote buildup: If we find Stage 2 or 3 creosote, we’ll recommend a second sweep within 3–6 months or a chimney liner /englewood-chimney-liner-installation-repair-smartest-upgrade/ to protect brick. - Cracked mortar: Small cracks can be repointed ($150–$400), but large gaps (over 3/8 inch) may require partial brick replacement ($800–$2,500). - Rust on damper: A sign of water intrusion. We’ll recommend a chimney cap /chimney-cap-crown-installation-englewood-protect-chimney-ele/ and waterproofing /chimney-waterproofing-englewood-stop-leaks-extend-chimney-li/. - Missing or damaged liner: If your chimney has no liner (common in pre-1980s homes), we’ll advise installing a stainless steel liner ($1,500–$3,000) to prevent brick erosion from heat and moisture.
Insurance note: Many homeowners’ policies cover chimney fires if you’ve had annual inspections USA.gov. Keep records of your sweeps to avoid claim denials.
How often should you book a sweep for a home with a pre-1980s brick chimney or a cracked mortar joint in Englewood?
Frequency depends on three factors unique to Englewood homes: | Chimney Type | Burn Frequency | Recommended Sweep Schedule | Notes | |---------------------------------|--------------------------|-------------------------------|--------------------------------------------| | Older brick (no liner) | Year-round use | Twice yearly (spring/fall) | High creosote risk; check mortar annually. | | Brick with liner | Seasonal use | Once yearly (fall) | Liner protects brick but doesn’t eliminate sweeps. | | Masonry veneer (modern homes) | Occasional use | Every 2–3 years | Lower risk but still needs inspection. | | Wood stove only | Heavy winter use | Twice yearly | Stoves create more creosote than fireplaces. |
Englewood exception: Homes near dry, windy areas (like the Rocky Mountains foothills) may need more frequent sweeps due to faster creosote drying. If you burn pine or fir (common in Colorado), schedule sweeps every 40–50 burns instead of annually.
| Chimney Condition | Burn Frequency | Recommended Sweep Schedule | Average Cost per Sweep |
|---|---|---|---|
| Older brick (no liner) | Year-round | Twice yearly (spring/fall) | $180–$300 |
| Brick with liner | Seasonal | Once yearly (fall) | $120–$220 |
| Masonry veneer (modern) | Occasional | Every 2–3 years | $100–$180 |
| Wood stove only | Heavy winter | Twice yearly | $200–$350 |
| After a chimney fire | Any | Immediate sweep + inspection | $250–$500 |
Frequently Asked Questions
My Englewood fireplace gives off a gas-like odor when I light it, should I be worried about my brickwork or liner?
No, this is carbon monoxide (CO) leaking from a blocked or improperly sized flue. Englewood’s older brick chimneys often have restricted flues due to creosote buildup or collapsed mortar. Never ignore this: Install a CO detector immediately and schedule a chimney inspection /compare/chimney-sweeping-vs-inspection/ before using the fireplace again. CO poisoning sends three Englewood residents to the hospital yearly during winter.
I see white powder on my fireplace hearth. Is this just soot, or something worse?
That white dust on your fireplace is efflorescence, a sign of moisture seeping into your brick or mortar. Englewood’s freeze-thaw swings force water into cracks, then leave behind salt deposits. Left alone, this causes brick flaking and weakens the structure. Act now: Repair cracked mortar /masonry-repairs-repointing-englewood-how-fix-crumbling-chimn/ and add a chimney cap to keep rain out.
My chimney has a ‘B’ sticker from a sweep last year. Do I still need another one?
A ‘B’ sticker means ‘clean but needs monitoring’, not ‘fully safe’. If you’ve burned wood since last year’s sweep, creosote has likely rebuilt. Rule of thumb: Sweep before your first fire of the season, regardless of stickers. Englewood’s dry winters turn creosote highly flammable in as little as 6 months. /blog/creosote-removal-englewood-types-risks-brick-chimney-health/ explains why ‘B’ stickers aren’t enough.
Could DIY sweeping save money for my Englewood home’s chimney, or is it a gamble with older brick and hidden dangers?
DIY sweeps are dangerous for Englewood’s older brick chimneys. Three risks: 1. Damaging brick with improper tools (e.g., wire brushes can scratch mortar). 2. Missing creosote in hard-to-reach spots (like smoke chambers in brick). 3. Igniting hidden fires if creosote is disturbed carelessly. Solution: Use a certified CSIA sweep /about/, they have insurance, liability coverage, and tools designed for Englewood’s brick masonry. A pro sweep costs $120–$250 but prevents $1,000+ repair bills from DIY mistakes.
