Professional Chimney Sweeping in Kennett Square, PA | Ace Chimney Sweeps

Kennett Square homeowners understand the value of a home that is well cared for from the ground up, and that includes what is happening inside the walls of your chimney. Chester County winters can be long and damp, and for many households in this part of Pennsylvania, a wood-burning fireplace or stove is not just a decorative feature but a meaningful source of heat and comfort. Keeping that system clean and well-maintained is one of the most responsible things you can do as a homeowner. At Ace Chimney Sweeps, we have been serving Kennett Square and the surrounding Chester County communities since 1986. Our technicians are certified by the National Fireplace Institute (NFI) and are proud members of the National Chimney Sweep Guild (NCSG), and we bring that training and experience to every chimney we service.

Does a Chimney Need to Be Cleaned Even If I Do Not Use the Fireplace Often?

This is a question we hear more than you might expect, and the answer is yes. Many homeowners assume that light use or occasional use means the chimney stays clean on its own. In practice, infrequent use can actually create its own set of problems that are worth taking seriously.

Here is why a rarely used chimney still benefits from regular professional attention:

Animals and insects move in during the off-season. A flue that sits unused through spring and summer is an inviting space for birds, squirrels, bats, and wasps. Nesting material is highly flammable and can significantly restrict airflow.
Moisture damage progresses regardless of use. Rain, snow, and humidity enter through an unprotected or deteriorating flue and cause mortar joints to crack, liner tiles to spall, and metal components to corrode year over year.
Even occasional fires generate creosote. A fire lit a handful of times each season still produces combustion byproducts that coat the flue walls. In fact, small and infrequent fires often burn at lower temperatures, which can actually accelerate creosote formation.
Out-of-sight problems go unnoticed. Without a professional inspection, issues that develop inside the flue over months or years can reach a more serious stage before anyone realizes they exist.

Annual service is the standard recommendation regardless of how often you light fires. The inspection alone has value that goes beyond the cleaning itself.

Kennett Square, PA: The Mushroom Capital of the World

Kennett Square wears its nickname proudly, and it has earned it. The borough produces more mushrooms than anywhere else in the United States, a distinction that has shaped the local identity, the economy, and even the restaurant scene in ways that make this small town genuinely one of a kind in Chester County.

The area’s most celebrated destination is Longwood Gardens, one of the premier horticultural showplaces in the country. Spread across more than a thousand acres just outside the borough, Longwood draws visitors from across the region and beyond for its conservatories, outdoor gardens, and seasonal displays that transform the landscape throughout the year. Closer to the center of town, Anson B. Nixon Park gives locals a welcoming green space for walking, sports, and community events.

The dining scene in Kennett Square punches well above its weight for a borough of its size. Sovana Bistro has built a reputation as one of the most respected restaurants in Chester County, with a menu that reflects the agricultural richness of the surrounding region. Portabellos of Kennett Square leans into the local mushroom heritage with a menu that celebrates what the area does best. Half Moon Restaurant and Saloon offers a more casual atmosphere and has been a local gathering point for years. And anyone familiar with the food world likely knows Talula’s Table, which turned a Kennett Square farmhouse kitchen into a nationally recognized dining destination.

This is a community with a clear sense of who it is, and we are glad to be a trusted service provider for the homeowners who make it home.

What Type of Wood Should I Be Burning in My Fireplace?

The fuel you put into your fireplace has a direct impact on how quickly your chimney gets dirty and how well your system performs throughout the season. This is one of those topics where the right habits from the start make a real difference over time.

The most important rule is to burn properly seasoned hardwood. Seasoned wood has been cut and allowed to dry for at least six months to a year, bringing its moisture content down to a range where it burns hotter and produces far less smoke and creosote than green or wet wood.

Hardwoods worth looking for include:

Oak, which burns slowly and produces a long-lasting, steady heat
Ash, which seasons relatively quickly and burns cleanly
Hickory, which burns hot and is widely available in this part of Pennsylvania
Cherry and maple, which burn well and are pleasant options for the firebox

Woods to avoid include any that are green or freshly cut, wood that has been treated or painted, plywood or manufactured lumber, and softwoods like pine or cedar as a primary fuel. Softwoods burn fast and produce significantly more resin and creosote than hardwoods, making them a poor choice for anything beyond getting a fire started.

You can tell wood is well-seasoned when it is lighter than you expect, has visible cracks radiating from the center of the cut end, and makes a hollow knocking sound when two pieces are struck together. Buying from a reputable local supplier and asking about moisture content is always a reasonable step.

What Happens If a Chimney Liner Is Damaged and I Keep Using the Fireplace?

The flue liner is the inner passageway of your chimney, and it is doing some of the most critical work in the entire system. When it is intact, it directs combustion gases out of the home, protects surrounding masonry from heat, and helps maintain the draft your appliance needs to perform as well as possible. When it is cracked, broken, or deteriorating, those functions are compromised in ways that can have serious consequences.

Continuing to use a fireplace with a damaged liner poses a few distinct concerns:

Heat transfer to combustible materials. A damaged liner allows heat and hot gases to reach the surrounding structure at much higher levels than an intact liner would. Wood framing inside walls that runs adjacent to the chimney can be affected over time.
Carbon monoxide intrusion. Combustion gases, including carbon monoxide, can find their way into living spaces through gaps and cracks in a compromised liner rather than exiting through the top of the flue as intended.
Accelerated deterioration. Using a damaged liner exposes the surrounding masonry to conditions it was not designed to handle, speeding up the breakdown of mortar joints and brickwork.
Reduced draft. Gaps in the liner allow air to enter the system in unintended ways, which disrupts the pressure differential that makes your chimney draw properly.

Liner damage is not always visible from inside the firebox. It often requires a camera inspection to identify clearly, which is something we can perform when circumstances call for it. If we flag liner concerns during your cleaning appointment, we will walk you through exactly what we found and what your options are for addressing it.

Why Does My Fireplace Smell Musty or Unpleasant When the Heat or Air Conditioning Is Running?

Fireplace odor is one of the more overlooked symptoms of a chimney that needs attention, and it is something Kennett Square homeowners notice most often during the summer months when the air conditioning is running and the house is closed up tight.

The underlying issue is almost always related to one of a few common causes:

Creosote and soot reacting to heat and humidity. Creosote is an organic material, and when temperatures rise and moisture enters the flue, that residue releases odor that travels down into the home through the firebox opening.
Animal or debris presence in the flue. Nesting material, droppings, or in unfortunate cases a deceased animal in the flue can produce persistent and unpleasant odors that are difficult to identify without looking inside the chimney.
Negative air pressure pulling air down the flue. When a home is sealed up and the HVAC system is running, it can create pressure dynamics that pull air from outside down through the chimney rather than allowing it to rise. That air carries whatever smell is inside the flue directly into the living space.

A thorough cleaning removes the organic material that odor clings to and significantly reduces or eliminates smell-related complaints in most cases. Installing or upgrading a top-mounted damper can also help by creating a tighter seal at the top of the flue when the fireplace is not in use, which limits the amount of outside air and humidity that enters the system between fires.
