Chimney Sweep Services Across Delaware County and the Main Line
Keeping up with routine chimney sweepings is one of the most effective ways to protect your home against chimney fires and keep your system performing season after season. At Lou Curley’s Chimney Service, we know that a real sweeping is more than running a brush up and down a flue. Our team holds certifications through the Chimney Safety Institute of America (CSIA), the National Fireplace Institute (NFI), and Fireplace Investigation, Research, and Education Services (F.I.R.E.), and we put every one of those credentials to work on every job.
We serve Drexel Hill, Havertown, Springfield, Media, Wayne, Bryn Mawr, Broomall, Newtown Square, and the surrounding Delaware County and Main Line communities. Ready to book? Request an appointment or call 610-626-2439.
Why a Lou Curley Sweeping Is a Better Sweeping
When you call Lou Curley’s Chimney Service for a sweeping, here is what sets the visit apart.
- A more thorough clean. For masonry fireplaces, we use rotary brushes (where appropriate) that attach to a drill and spin-clean the interior of the flue. That removes far more soot and creosote than a wire brush can on its own.
- A video scan with every fireplace inspection. A flashlight check from the firebox can catch the obvious. It cannot give you a real look at the full flue. Every fireplace inspection we perform includes a video scan from top to bottom, and if we find a defect we show you the footage. You do not have to take our word for anything.
- Credentials that mean something. Chimney sweeping is an unregulated trade in much of the country, which means anyone with a brush and a ladder can call themselves a sweep. Our team holds certifications through the CSIA, NFI, and F.I.R.E., and Lou Curley is PA’s first CSIA Master Chimney Sweep. Employee Dave Curley also holds CSIA Master Chimney Sweep certification.
How Often Should You Have Your Chimney Swept?
Frequency depends on how you use the system. Burning habits, the type of wood you use, house pressure, and a long list of other factors all affect how quickly soot and creosote build up.
The standard to know is from the National Fire Protection Association (NFPA): every chimney should be inspected annually, whether it vents a fireplace, stove, gas furnace or boiler, or oil furnace or boiler. If the inspection finds a soot or creosote buildup of one-eighth of an inch or greater, the chimney should be swept. The takeaway is that the annual inspection is the constant. The cleaning happens when the inspection says it should.
Why a Regular Sweeping Schedule Matters
Every time you burn a fire, acidic gases and particulate matter from combustion collect on the interior walls of your chimney. Over time those deposits form creosote: a flammable, corrosive substance that is the single biggest cause of chimney fires in the United States. Creosote also degrades the inside of the flue, which lets heat and gases interact with parts of the chimney that were never meant to see either.
Even if you rarely use your fireplace, you still need an annual inspection. Animals find unprotected flues. Caps fail. Liners crack on their own timeline. A once-a-year look at the system is what catches the small problem before it becomes the expensive one.
Why Different Creosote Stages Need Different Cleaning Methods
Creosote does not look the same in every chimney. The composition depends less on the type of wood and more on how the system has been operated and maintained.
- Stage 1 (light, flaky). This is the version you want. Light, dusty deposits that a CSIA-trained sweep can remove with a brush. You get stage 1 creosote when the system has good draft and the operator burns properly seasoned wood at high temperatures.
- Stage 2 (shiny, congealed). When the chimney is not getting enough combustion air, the fire burns cooler and dirtier. The result is creosote with hardened tar mixed in. A regular chimney brush will not touch it. We use more aggressive tools to break it up before brushing.
- Stage 3 (glazed). This is the worst case: a thick, hardened tar coating that reforms with every new fire. Causes range from an undersized flue to a poorly insulated chimney. In severe cases the most cost-effective fix is a new stainless steel liner, because the existing liner is no longer safe to use.
How is stage 3 (glazed) creosote removed?
Ultimately, it depends on every individual situation, but sometimes, in cases where the amount of glazed creosote is extremely high, the best course of action is to remove and replace the chimney liner to ensure optimal and efficient performance. Though, it is also possible for a chimney expert to apply specially formulated products meant to soften the hardened creosote deposits making removal easier and safer for your entire structure.
Are Creosote Sweeping Logs a Substitute for a Real Sweeping?
No. They have a place as a supplement, but they are not a replacement.
Sweeping logs contain additives that, when burned, latch onto creosote deposits and help break them down. That is genuinely useful. What they cannot do is remove the broken-down deposits from the chimney. That part still requires a professional sweep with the right tools. Use a sweeping log if you want. Just do not let it stand in for the annual visit from a certified sweep.
How to Treat Your Chimney Well Between Sweepings
A few habits will keep your system cleaner and safer year-round.
What to Look For When You Hire a Chimney Sweep
Because the industry is unregulated, training varies enormously from company to company. The minimum bar to look for is CSIA-certified Chimney Sweep credentials, which require passing tests on sweeping practices and code requirements. Beyond that, look for additional credentials (NFI, F.I.R.E., CSIA Master Chimney Sweep), proof of liability insurance, and a valid Pennsylvania Home Improvement Contractor’s License. Lou Curley’s Chimney Service carries all of the above.
When Is the Best Time to Schedule Your Sweeping?
The best window is spring or early summer, right after the burning season ends. Soot and creosote are corrosive, so getting them out of the chimney as soon as the season is over limits the damage they can cause sitting in the flue all summer. Spring scheduling also gets you in before the fall rush, when our calendar fills up fast.
