What is creosote, and why is it dangerous?

Creosote is a highly flammable, tar-like substance that builds up inside your chimney from burning wood. A significant buildup can lead to a chimney fire.

How often do I need a chimney inspection or cleaning?

The National Fire Protection Association (NFPA) recommends an annual inspection for all fireplaces, chimneys, and vents, regardless of how often you use them. Cleaning is performed as needed based on the inspection.

Why is dryer vent cleaning so important?

• Fire safety: Lint is combustible, and restricted airflow can cause heat to build inside the dryer and vent system.

• Drying performance: A clear vent helps the dryer move moisture and heat outdoors, which can reduce drying time.

• Gas-dryer safety: A restricted vent can prevent combustion gases, including carbon monoxide, from exhausting properly.

• Dryer life: Excessive heat and long run times place additional stress on the appliance.

Viking checks airflow and backpressure so you receive more than a basic brush cleaning.

How often should I have my dryer vent cleaned?

Most professionals and safety organizations recommend cleaning your dryer vent at least once a year. The frequency can increase depending on factors like:

• How often you use your dryer (large families, etc.).

• The length and configuration of your vent (longer vents with more bends and turns collect lint faster).

• Whether you have pets that shed a lot.

What are the different types of chimney inspections?

NFPA 211 describes three inspection levels:

• Level 1 evaluates readily accessible portions of a system that has not changed and is expected to continue under the same conditions.

• Level 2 includes additional accessible areas and a video scan of the flue when accessible. It is commonly recommended during a real-estate transaction, after a system change or following an event that may have caused damage.

• Level 3 includes opening concealed areas only when needed to investigate a serious suspected hazard that cannot be fully evaluated through Level 1 or Level 2 inspection.

Do I need a chimney cap?

A properly fitted chimney cap helps reduce rain entering the flue and helps keep out animals and debris. However, a cap does not waterproof the masonry or correct leaks caused by a cracked crown, failed flashing, damaged chase cover or deteriorated mortar. The entire chimney should be evaluated when water intrusion is present.

When is the best time of year to schedule an inspection?

Late spring or summer is often recommended. This is before the busy fall season, making it easier to get a convenient appointment.

I have wasps coming into my fireplace. What should I do?

Wasps can enter even when a chimney has a cap because standard chimney-cap screening is designed for larger animals and debris, not insects. Regular fireplace use may discourage nesting but cannot guarantee prevention. If wasps are actively entering the home, contact a licensed pest-control professional first. After the nest is inactive, I can inspect the cap, damper and fireplace for damage or larger openings.

Will my chimney automatically be swept during the inspection?

Not necessarily. Cleaning is performed only when the inspection shows it is needed. When a sweep is recommended and can be completed during the same appointment, it is available as a $75 add-on to the fireplace and chimney inspection.

What should I look for when hiring a chimney company?

Verify the certification of the individual technician who will actually inspect or repair your system—not only the company name. Look for relevant credentials such as NCSG chimney certification, NFI gas certification or CSIA dryer-vent certification, depending on the work being performed. Also confirm insurance, read recent reviews and expect clear written findings, photographs and pricing before approving repairs.

What are the signs that my chimney needs cleaning or repair?

Common signs include a strong smoky smell, smoke backing up into the room, poor fire performance, soot or creosote visible on the damper, and animal noises coming from the chimney.

Will it make a mess in my home?

A professional chimney sweep will take steps to protect your home from dust and soot, using tarps and specialized vacuums. They will prepare the area to ensure a clean process.

My gas fireplace doesn't produce creosote. Do I still need an inspection?

Yes. Gas fireplaces do not produce wood-burning creosote, but the appliance, pilot or burner, controls, firebox, venting and termination still need evaluation. Depending on the type of gas system, an inspection can identify deteriorated components, venting problems, blockages, corrosion or signs of improper combustion. Viking’s gas-fireplace work is performed by an NFI Gas Specialist.

Do "chimney sweeping logs" actually work?

These logs are not a substitute for a professional cleaning. While they may help break down some creosote, they do not remove the substance and should only be used as a supplement to professional maintenance.

What can I expect when you show up at my house?

A professional chimney inspection is a thorough check of your chimney's safety and condition. The main goal is to ensure it is operating correctly and not a fire or health hazard.

A certified inspector will:

• Visually check everything accessible. They will look at the chimney from the outside, including the cap, crown, and bricks. They will also inspect the inside components, such as the firebox, damper, and smoke chamber.

• Look for flammable buildup. The inspector's most important task is to check for creosote, a highly flammable substance that builds up inside the chimney and is a leading cause of chimney fires.

• Check for damage and blockages. They will look for cracks in the bricks, mortar, or the flue liner that could allow heat or dangerous gases into your home. They'll also check for any obstructions like animal nests, leaves, or other debris that can block the chimney.

• Use a camera to see inside the flue. To get a complete view of the chimney's interior, a professional will use a special camera. This lets them see hidden problems that a simple visual check would miss, such as a damaged or cracked liner.

After the inspection, you will receive a detailed report outlining their findings and any recommended repairs.
