Forest Green Chimney Corp clears flue blockages, creosote, soot, and debris, that fuel chimney fires and carbon monoxide leaks. In Fort Washington’s pre-1980s homes, where brick chimneys dominate, yearly sweeps are critical, especially after heavy use. The Chimney Safety Institute of America advises sweeping at least once a year, or more often if you burn damp wood or rely on your fireplace daily. Neglecting buildup lets creosote harden into a flammable tar that ignites at 1,100°F, threatening to engulf your home’s structural wood. If your chimney emits a gas-like odor, shows black streaks, or puffs excessive smoke, call us, our Fort Washington crews respond to emergencies the same day.
1. What is a chimney inspection, and why does Jenkintown’s building code require it before every sweep?
A chimney inspection examines your flue, smoke chamber, and chimney structure for dangers like cracks, rust, or creosote accumulation that could spark a fire or leak carbon monoxide. Jenkintown follows Montgomery County’s adoption of the National Fire Protection Association’s (NFPA) standards, which mandate a Level 1 inspection before every sweep if you’ve used your fireplace in the past year. This isn’t just bureaucracy, it’s safety. During a recent sweep in a Jenkintown home on Ridge Avenue, our crew found a hairline crack in the flue liner that could’ve let carbon monoxide into the living space. The homeowner had no idea; the crack was hidden behind soot. If you’re selling your home or financing a mortgage, lenders often require a Level 2 inspection (which checks masonry and structural integrity). Contact us for a written quote to schedule a certified inspection before your next sweep, especially if your chimney is over 20 years old, like many in Fort Washington’s historic neighborhoods.
The EPA’s Burn Wise program notes that improperly maintained chimneys release up to 30% more pollutants than clean ones, worsening air quality in tight-knit communities like Jenkintown. If your last chimney inspection was over a year ago, schedule one today to spot hidden risks before they worsen. Prices start at $120 for a Level 1 inspection in Jenkintown, with Level 2 inspections (required for older homes) ranging from $180–$350 depending on chimney height and access. See our pricing guide for details.
2. My chimney smells like gas after lighting a fire, is this carbon monoxide, and how do I know if it’s an emergency?
Yes, a gas-like or sweet odor after lighting your fireplace is almost always carbon monoxide (CO) leaking from your chimney. CO is odorless and colorless, but when it mixes with soot or creosote, it creates a faint chemical smell, like rotten eggs or burning plastic. This is an emergency. Carbon monoxide poisoning sends over 50,000 Americans to the ER yearly, and older homes in Abington and Glenside, with their brick-and-mortar construction, are particularly vulnerable due to draft issues. If you or anyone in your household experiences headaches, nausea, or dizziness after using the fireplace, evacuate immediately and call 911. Then, contact a chimney sweep to inspect for cracks, blocked flues, or failed dampers.
In Fort Washington, we’ve seen CO leaks traced to three common issues: a collapsed flue liner (often from creosote buildup), a rusted damper that doesn’t seal, or a chimney too narrow for your fireplace’s output. For example, a Glenside home on Church Road had a CO alarm go off after installing a high-efficiency insert, its flue was too small for the new appliance’s airflow. The fix? A relined flue and a sweep to remove years of ignored creosote. Learn how to spot a CO leak before it’s too late. If your CO detector sounds during fireplace use, don’t wait, schedule an emergency inspection. Our crews in Jenkintown offer same-day service for CO-related calls, with inspections starting at $150.
3. Why does my Jenkintown fireplace smoke excessively, even with dry wood? Could it be a blocked chimney?
Excessive smoke means your chimney isn’t drawing properly, a red flag for a blocked flue, creosote buildup, or a structural issue. In Jenkintown’s dense housing, where chimneys often share walls with neighboring properties, draft problems are common. If smoke rolls into your room instead of up the chimney, your flue might be clogged with creosote, bird nests, or debris. The Chimney Safety Institute of America (CSIA) warns that even a 1-inch restriction in flue diameter can reduce draft by 50%. We recently cleared a chimney in Abington where a squirrel had nested for two winters, leaving only a 2-inch gap for smoke to escape, no wonder the homeowner’s fireplace smoked like a factory.
Other causes: a cracked flue liner (allowing outside air to disrupt the draft), a damaged chimney cap (letting rain or debris block the top), or a fireplace too large for your chimney’s size. For instance, a Glenside home on School House Road had a 12-inch flue but a 24-inch fireplace, smoke had nowhere to go. The fix? A chimney sweep to clear creosote ($180–$250) and a CSIA-certified technician to assess if your fireplace needs downsizing or a larger flue liner ($1,200–$3,000). See our guide on fireplace-to-chimney sizing. If smoke lingers for more than 10 minutes after lighting, call a chimney sweep immediately, prolonged smoke exposure damages your home’s air quality and risks CO buildup.
4. How often should I schedule a chimney sweep in Jenkintown, and does my wood type affect the frequency?
The Chimney Safety Institute of America advises homes that use fireplaces regularly to sweep at least once every 12 months. But in Jenkintown, where many homeowners burn wood seasonally, the frequency depends on your fuel and usage. Wet or resinous wood (like pine) creates more creosote than seasoned hardwoods like oak or maple. If you burn wet wood, you may need sweeps twice a year, or more if your chimney smokes excessively. Here’s a quick guide for Jenkintown homeowners:
| Usage Level | Recommended Sweep Frequency | Creosote Risk | Estimated Cost (Jenkintown) | |-------------------------------|--------------------------------|---------------------------|--------------------------------| | Light use (1–2 fires/week) | Once a year | Low (Stage 1 creosote) | $120–$180 | | Moderate (3–5 fires/week) | Twice a year | Medium (Stage 2) | $200–$300 | | Heavy (daily use) | Every 3–4 months | High (Stage 3, flammable)| $250–$400 | | After a chimney fire | Immediately + annual after | Critical | $300–$600 (emergency) |
For example, a Jenkintown homeowner who burns cordwood from a local supplier (often damp) needed a sweep every 4 months to avoid Stage 3 creosote, a tar-like substance that can ignite spontaneously. Learn how to season wood properly. If you’re unsure about your creosote stage, ask during your inspection. Our crews use a flashlight and chimney camera to check for glaze (a shiny, glass-like coating on creosote that signals danger).
5. My chimney has black stains on the fireplace surround, is this just soot, or could it be a chimney fire hazard?
Black stains on your fireplace surround or mantel are almost always soot, but the type of soot matters. Dry, powdery soot is normal and easy to clean. But if the stains are sticky, tar-like, or have a shiny, glassy texture, you’re dealing with creosote, especially if it’s Stage 2 or 3. Stage 3 creosote looks like black, crusty tar and is highly flammable. The NFPA reports that creosote is the leading cause of chimney fires, accounting for 25% of all residential fires. In Fort Washington, we’ve seen chimney fires start from ignored creosote in homes where the homeowner thought ‘a little soot’ was normal.
Here’s how to tell the difference: - Soot: Dry, flaky, easy to wipe off with a damp cloth. - Stage 1 Creosote: Gummy, tar-like, sticks to fingers. - Stage 2 Creosote: Hard, crusty, resembles burnt sugar. - Stage 3 Creosote: Shiny, glassy, resembles asphalt, this is an emergency.
If your stains are sticky or glossy, schedule a sweep immediately. Our Jenkintown crews use rotary brushes and high-pressure air to remove creosote safely, even in tight flues. Prices for creosote removal start at $180 for light buildup but can reach $400+ for severe cases requiring chemical treatments. See our creosote removal guide. Pro tip: Install a chimney cap to reduce soot buildup, many Jenkintown homes lose heat and draft through open chimney tops, worsening creosote formation.
6. My chimney leaks water into my living room, is this a masonry repair job, or can a sweep fix it?
A leaking chimney is almost never fixed by a sweep alone. Water entry usually means cracked masonry, a failed chimney cap, or a deteriorated flue liner. In Jenkintown’s humid climate, where rain and snow test chimneys year-round, leaks are common in older homes with brick chimneys. If water drips into your home during rain or snowmelt, you likely need: 1. A chimney cap replacement ($200–$500) to block rain and debris. 2. Tuckpointing ($1,000–$3,000) to repair cracked mortar between bricks. 3. Flue liner repair or replacement ($1,500–$4,000) if the liner is corroded.
We recently inspected a Glenside home where water had eroded the flue liner, causing rust to flake into the fireplace, dangerous and unsightly. The fix? A stainless-steel liner ($2,800) and a new cap. Learn how to spot masonry damage. If your chimney leaks, don’t wait, water damage weakens masonry and accelerates creosote buildup. A sweep alone won’t stop leaks, but it can reveal hidden damage during the inspection. Always ask for a moisture test if you suspect leaks; our crews use thermal imaging to detect hidden water intrusion in Jenkintown chimneys.
7. Can I use my fireplace after a chimney sweep, or do I need to wait? What if I smell gas afterward?
You can use your fireplace immediately after a sweep, unless the technician finds hazards like a cracked flue or CO leaks. If your chimney passes inspection with no issues, light a small fire to test the draft. But if you smell gas after the sweep, turn off the fireplace and ventilate the room. This could mean: - A blocked damper (common in older Jenkintown homes with manual dampers). - A failed CO detector (replace batteries or the unit). - A new creosote buildup from a recent fire (schedule a follow-up sweep).
The EPA’s Burn Wise program advises waiting 24 hours after a sweep if heavy creosote was removed, to let any lingering dust settle. But for routine sweeps, you’re safe to use your fireplace right away. See our post-sweep checklist. Pro tip: After lighting, watch the fire for 10 minutes. If smoke backs into the room or the fire flickers weakly, relight it, this often signals a draft issue that needs a chimney cap or liner adjustment. If in doubt, call us for a quick draft test ($50 add-on in Jenkintown).

Frequently Asked Questions
My Jenkintown home has a gas fireplace, do I still need a chimney sweep?
Yes. Gas fireplaces still need yearly sweeps to clear soot, rust, and corrosion from the vent. Even without wood fires, condensation in the flue can still form creosote. The NFPA mandates annual checks for gas vents to rule out blockages or rust. In Fort Washington, we’ve found gas chimneys jammed with bird nests or sealed shut by rust, both serious fire risks. Book a sweep before fall to prevent draft problems when you switch to heat. Learn gas fireplace maintenance tips
Why does my Abington chimney smell like sulfur after lighting a fire? Is this normal?
A sulfur or rotten-egg smell means your wood is burning wet or green. Sulfur compounds in unseasoned wood release when burned, creating that odor. It’s not dangerous but wastes fuel and increases creosote buildup. Season your wood for 6–12 months in a dry, covered area. Fort Washington’s humidity makes this tricky, so stack wood under a tarp. If the smell persists, your chimney may have a draft issue or a blocked flue. See how to season wood properly.
My Glenside chimney hasn’t been swept in 5 years, how much will it cost to catch up, and is it safe to use?
Never use an unswept chimney, 5 years of ignored buildup can mean Stage 3 creosote, which ignites at 1,100°F. Costs vary: a basic sweep starts at $180, but severe buildup may require chemical treatments ($300–$500) or even a flue reline ($1,500–$4,000). If your chimney is structurally sound, we’ll sweep it safely in sections. However, if you’ve had fires or smoke issues, we’ll inspect for damage first. Get a written quote for your Glenside home. Pro tip: Open windows during the sweep to ventilate creosote dust.
I found a bird’s nest in my Jenkintown chimney, can I remove it myself, or should I call a chimney sweep?
Never remove a nest yourself, birds often use chimneys for insulation, and disturbing them can leave feathers, nesting material, and debris that block the flue. Our crews use specialized tools to clear nests safely, then inspect for creosote or damage. DIY removal risks damaging the flue liner or leaving debris behind. In Jenkintown, we’ve seen nests packed with twigs and mud that took hours to clear. Schedule a sweep ($150–$250) to remove the nest and check for hazards. See our bird nest removal process.
