If you've searched "why is chimney sweeping so expensive," you've probably seen numbers like $150–$350. That range is accurate — and DME Maintenance publishes our exact prices so you don't have to guess. Gas flue cleaning: $185. Oil flue cleaning: $220. Wood fireplace sweep: $275. Wood or pellet stove: $299. Every cleaning includes a Level 1 safety inspection and written report at no extra charge.
What You're Actually Paying For
A chimney cleaning is not a guy with a brush. It's a trained technician on your roof with a HEPA vacuum, specialized rotary brushes, a video camera for flue inspection, and the insurance to cover working at height on your property. DME Maintenance carries full liability and workers' compensation insurance — which costs thousands per year. That overhead is baked into the price, and it's what separates a legitimate sweep from a Craigslist ad.

Why Wood Costs More Than Gas
Gas appliances produce minimal residue — mostly acidic condensate that attacks the liner over time. Cleaning takes less time and less material. Oil systems leave heavier soot but it's soft and brushes out quickly. Wood-burning fireplaces produce creosote — a tar-like byproduct that can be rock-hard at Stage 3. Removing heavy creosote requires chemical treatments, aggressive mechanical scraping, and significantly more time. That's why a wood fireplace sweep costs $275 vs $185 for gas.
The $49 Chimney Sweep Scam
If someone offers a $49 chimney cleaning, they're not planning to make money on the cleaning. They're planning to get inside your house, find something "wrong," and pressure you into $2,000–$5,000 in repairs you may not need. This is documented by the Better Business Bureau and the Chimney Safety Institute of America (CSIA). A legitimate chimney cleaning in Nassau County costs $185–$299 depending on fuel type. Anyone quoting significantly below that is either uninsured, unlicensed, or running a bait-and-switch. DME Maintenance is licensed (#H0101570000), insured, owner-operated since 2001, with a perfect Consumer Affairs record.
