Chimney Cleaning & Creosote Removal
E Cleaning removes soot, creosote, and blockages from chimneys and fireplaces across the greater Philadelphia suburbs. Every job starts with a free inspection, and you get a flat, written quote before we touch a brush — because no two chimneys carry the same buildup, we never quote yours sight unseen.
We are a family-owned company based in King of Prussia, serving the area since 2016. We are a PA licensed contractor (PA 187935), insured up to $2 million, and Google Guaranteed with money-back protection up to $2,000 on qualifying jobs. The same inspect-first, show-your-work approach we built our duct cleaning business on applies to every chimney we touch: we look before we quote, we quote before we clean, and we show you photos when we are done.
A chimney is one of the few systems in your house that handles live fire, so we treat it that way. Whether you burn wood every night from November through March or light the fireplace twice a year for the holidays, the flue collects residue every single time — and the only way to know how much is up there is to look.
What does professional chimney cleaning include?
Chimney cleaning means removing the soot, creosote, and physical blockages that build up between the firebox and the top of the flue — not just sweeping visible ash out of the fireplace. A proper cleaning covers the full path smoke travels.
- Flue walls — brushed and agitated top to bottom to break loose soot and creosote deposits
- Smoke shelf and smoke chamber — the ledge behind the damper where debris and creosote collect heaviest
- Damper area — cleaned and checked so it opens, closes, and seals the way it should
- Firebox — soot and ash removed down to the masonry
- Blockage removal — bird and animal nests, leaves, and fallen brick or mortar cleared from the flue
- Containment and cleanup — drop cloths, sealed openings, and HEPA-filtered vacuum equipment so the mess stays in the chimney, not your living room
Why does creosote buildup matter?
Creosote is a flammable residue left behind every time wood burns. Smoke cools as it rises through the flue, and the tars and vapors it carries condense on the flue walls. Layer by layer, fire by fire, that residue builds — and because it is a fuel, a thick enough layer can ignite inside the chimney itself.
Creosote gets harder to remove the longer it sits. Fresh deposits are a dusty soot that brushes out easily. Left alone, they mature into crunchy, flaky tar — and eventually into a glazed, hardened coating that ordinary brushing barely touches. That is one honest reason chimney cleaning cannot carry a single flat price: a flue with a light dusting of soot and a flue coated in glazed creosote are two very different jobs.
Burning habits matter too. Unseasoned or wet wood, smoldering low-temperature fires, and a restricted damper all produce cooler, smokier exhaust — exactly the conditions that deposit creosote fastest. If that describes last winter in your house, it is worth having the flue looked at before you light the next fire.
When should you have your chimney cleaned?
The best times are before burning season starts and after any winter of heavy use — and immediately if you notice warning signs. National fire-safety guidance calls for having chimneys inspected every year and cleaned whenever buildup or blockages are found, regardless of how often you burn.
- Before burning season — late spring through early fall is ideal. You beat the October rush, and the flue is clean and clear the first cold night you want a fire.
- After heavy use — if the fireplace or wood stove ran regularly all winter, have the buildup removed rather than letting it harden over the summer.
- After sitting unused — a chimney that has been idle for a year or more should be inspected before you burn. Idle flues are where we find nests, leaves, and debris.
- When you see the signs — smoke drifting back into the room, a campfire smell even with no fire lit, black flakes or soot falling into the firebox, weak draft, or animal noises in the flue.
- Before buying or selling a home — an inspection tells you what shape the chimney is actually in before it becomes your problem.
If you are not sure whether your chimney needs cleaning this year, that is exactly what the inspection is for — we look first, and if the flue is genuinely clean, we will tell you so.
How does our inspection-first approach work?
We inspect before we quote, and we quote before we clean. You know exactly what we found and exactly what the job costs before any work starts — the same anti-surprise approach we bring to every duct and vent we clean.
Everything stays protected while we work: drop cloths down, the fireplace opening sealed, and HEPA-filtered vacuum equipment running so soot and creosote dust never reach your furniture.
Inspect
We examine the firebox, damper, smoke chamber, and flue to see how much soot and creosote is present, what stage it has reached, and whether anything is blocking the chimney.
Quote
You get a firm written price based on what we actually found — chimney height, buildup condition, and any blockages. Approve it, and we get to work. Decline it, and there is no pressure.
Protect
Drop cloths cover the hearth and floor, the opening is sealed, and HEPA-filtered vacuum equipment captures dust at the source while we clean.
Clean
We brush and agitate the flue walls, smoke chamber, smoke shelf, damper, and firebox, and physically remove nests and debris until the passage is clear.
Show you
We walk you through what came out and take after-photos, so you can see the condition of your chimney without climbing anything.
How much does chimney cleaning cost?
Chimney cleaning is quoted after a free inspection — we never price a flue sight unseen, on purpose. Chimneys vary too much for one honest number: a single-story flue with light soot is a fundamentally different job than a three-story chimney coated in glazed creosote with a nest on the smoke shelf.
| What we look at | Why it affects the price |
|---|---|
| Chimney height and stories | Taller flues mean more surface area and more setup |
| Stage of creosote | Loose soot brushes out quickly; hardened, glazed creosote takes far more work to remove |
| Blockages | Nests, leaves, and fallen debris add removal time |
| Access and condition | Damper, smoke chamber layout, and how the chimney can be safely reached |
This is the same inspect-first standard we hold across every service we offer: a free inspection, then a flat, written quote before any work begins. We are the same company that calls out the $49–$99 whole-house duct special as a bait-and-switch, and the same trick exists in the chimney world — a rock-bottom sweep price at the door that balloons once someone is standing in your living room. Our answer is the opposite: inspect first, quote in writing, and the number you approve is the number on the invoice. No trip fees anywhere in our service area, no door-step upsell.
Larger jobs can be financed through Wisetack, and we are available around the clock, Sunday through Friday — we're closed Saturdays.
Can you clean my ducts and dryer vent on the same visit?
Yes — many customers bundle chimney cleaning with air duct or dryer vent cleaning and knock out every exhaust path in the house in one appointment. One crew, one visit, one written quote covering everything before we start.
Air Duct Cleaning
A free video inspection inside the ducts shows you exactly what is in your system before any work — then you get a flat, written quote to approve.
Dryer Vent Cleaning
Lint buildup is a leading cause of dryer fires — another flue worth keeping clear. Inspected first, quoted flat in writing, then cleaned end to end.
Transparent Quotes
Free inspection first, then one flat, written number you approve before we start — for chimneys, ducts, and vents alike. No trip fees, no door-step upsell.
Skip the phone tree. We call you.
Drop your number and a real person from our King of Prussia office calls you back — usually within minutes, day or night (we run 24 hours, Sunday–Friday).
No robocalls, no spam — one call from us about your ducts, that's it.

Chimney Cleaning Questions
How often should a chimney be cleaned?
Have the chimney inspected every year and cleaned whenever the inspection finds meaningful soot, creosote, or a blockage — that is the widely followed national fire-safety standard. Households that burn wood regularly through the winter usually need a cleaning every season; occasional burners may go longer, but the annual look is what tells you either way. Buildup depends on how you burn, not just how often, so wet wood or smoldering fires can dirty a flue quickly.
Why don't you advertise a flat price for chimney cleaning?
Because a one-size-fits-all chimney price is either padded or bait. Chimneys vary enormously — height, stories, stage of creosote, blockages, damper condition — so one number cannot honestly cover them all. A company advertising a rock-bottom sweep price typically makes it back with add-ons once they are inside. We do the opposite on every service: a free inspection first, then a flat, written quote before any work starts — for chimneys, air duct cleaning, and dryer vents alike. The number you approve is the number you pay.
What is creosote and why is it dangerous?
Creosote is the flammable residue that condenses on flue walls when wood smoke cools on its way up the chimney. It starts as loose soot, matures into flaky tar, and can eventually harden into a glazed coating. Because creosote is a fuel, a thick layer can ignite inside the flue — a chimney fire — which can crack the liner, damage masonry, and expose nearby framing to extreme heat. Removing it before it accumulates is the point of routine chimney cleaning.
When is the best time of year to schedule chimney cleaning?
Late spring through early fall. Cleaning after the burning season removes creosote before it sits and hardens all summer, and scheduling before fall means you skip the October–November rush when every sweep in the Philadelphia suburbs is booked out. Either way, the goal is the same: a clean, clear flue before the first fire of the season, not after.
What are the signs my chimney needs cleaning now?
Smoke drifting back into the room instead of drawing up, a campfire or tar smell even when nothing is burning, black flakes or soot dropping into the firebox, a visibly oily or crusted flue wall, weak or lazy fires, and scratching or chirping sounds that suggest a nest. Any one of these is reason to stop burning and have the chimney inspected before the next fire.
Do gas fireplaces need chimney cleaning too?
Gas burns much cleaner than wood, so gas flues do not build creosote the way wood-burning chimneys do — but they still need attention. Vents can be blocked by bird nests, leaves, or debris, and a blocked flue is a problem no matter what fuel you burn, because combustion gases need a clear path out of the house. An annual inspection is cheap insurance; if we find the flue clear, we will tell you so.
Will chimney cleaning make a mess in my house?
No. We lay drop cloths over the hearth and surrounding floor, seal the fireplace opening, and run HEPA-filtered vacuum equipment while we brush, so soot and creosote dust are captured at the source instead of drifting into the room. When we finish, the firebox is cleaner than we found it and the living room looks untouched — and we show you after-photos of the flue.
How long does a chimney cleaning take?
Most straightforward cleanings take roughly one to two hours. Heavy or glazed creosote, a blocked flue, or a tall multi-story chimney can take longer — which is exactly why we inspect first. After the inspection we can tell you both the firm price and a realistic time estimate before you approve the work, so there are no surprises on either front.
