What certifications should a chimney sweep have?

Look for a sweep certified by the Chimney Safety Institute of America (CSIA). It is the credential Fairfax County Fire and Rescue points homeowners to, and it is earned by passing an exam on chimney and venting inspection and maintenance. For stoves, inserts and fireplace installs, a National Fireplace Institute (NFI) certification is worth asking about too. And if the job includes repairs, the business needs a Virginia contractor licence.

The credential fire departments name

Fairfax County Fire and Rescue advises having chimneys inspected annually, and cleaned as necessary, by a CSIA (Chimney Safety Institute of America) certified chimney sweep.^[4] Prince William County's fire and rescue system tells residents to have a certified chimney specialist clean fireplaces and wood stoves annually.^[6]

To become a CSIA Certified Chimney Sweep, a sweep has to complete a CCS review and pass the CCS exam.^[2] The review can be the CSIA's six-day training academy, a one-day review class or a self-paced online course, and the one-day class works from CSIA's Chimney and Venting Essentials manual.^[2] The credential runs on a three-year cycle, and in the third year it has to be renewed, either by retesting or by earning continuing education units.^[2] A certificate from years ago may have lapsed, so ask whether it is current.

The CSIA describes its Certified Chimney Sweep credential as the measure of a chimney and venting tech's knowledge of the evaluation and maintenance of chimney and venting systems.^[1] It is not a licence, and it does not cover the business's insurance or its contracts. It does tell you the person in your living room has passed a test on how chimneys should be inspected and cleaned.

Other CSIA credentials

You may see three more on a sweep's van or website:

• Certified Chimney Specialist (CSP). The Certified Chimney Specialist (CSP) is for pros who have committed to ongoing education beyond what the Certified Chimney Sweep requires.^[1]
• Master Chimney Sweep (MCS). The CSIA says the Master Chimney Sweep (MCS) is for long-term certification holders with a decade or more of ongoing education.^[1]
• Certified Dryer Exhaust Technician (CDET). The Certified Dryer Exhaust Technician (CDET) is the CSIA's certification for people who service dryer vents,^[1] useful if you want the dryer vent cleaned on the same visit.

NFI certification for stoves, inserts and installs

The National Fireplace Institute certifies specialists through rigorous testing on the service and installation of fireplaces, stoves and inserts.^[3] The topics include safety clearances, national building codes, hearth appliance requirements, fuel delivery, venting applications, combustion, and post-installation inspection and service.^[3] If you are adding a wood stove, an insert or a new fireplace, or the sweep will be servicing one, an NFI certification shows that knowledge has been tested.

What a certification will not tell you

EPA's Burn Wise guidance says one of the best ways to find competent installation and maintenance professionals is to check their credentials,^[5] and fire officials recommend a professional inspection of the appliance, chimney and vent each year.^[5] A test passed is a starting point, not proof of good work. Ask a few questions before you book:

• What will the visit include? Ask whether it covers the whole flue and the appliance, and whether the sweep will camera-scan the flue. What a chimney sweep does explains the visit.
• Will I get a written report? Ask whether it includes photos or a camera scan.
• Who does the work? A company can hold a certification through one employee while someone else is sent to your house. Ask whether the person coming is certified.
• Can I see references? The Board for Contractors' advice for any contractor applies here too: "Ask the contractor for local references, and call them".^[9]
• Is the business insured? Ask for proof of liability insurance before anyone goes on your roof.

Where Virginia licensing comes in

Certification is voluntary. Licensing depends on the work. The Board for Contractors' list of specialty services has no chimney-sweep specialty,^[7] so cleaning and inspecting a chimney is not tied to a licence category of its own.

Repairs are contracting work, and the price decides the class. The Code of Virginia says Class C contractors are those working on single contracts over $1,000 but less than $30,000,^[8] and larger jobs need a higher class. The specialty matters as well. Under the Board's definitions, masonry contracting (BRK) covers brick, block and stone work, including tuck pointing and parging, and the home improvement (HIC) specialty also provides for it.^[7] Gas is separate: "The HIC specialty does not provide for electrical, plumbing, HVAC, or gas fitting functions."^[7] Gas fitting contracting is its own specialty, covering the installation, repair, improvement or removal of gas piping and appliances annexed to real property,^[7] so a gas line or gas insert connection is work for a business licensed for it.

Check the licence yourself rather than relying on the paperwork. DPOR's consumer guide warns: "A license number in an advertisement or on a business card does not necessarily mean the contractor’s license is valid."^[9] How to check a contractor's licence shows the DPOR search, and whether it is illegal to hire an unlicensed contractor covers what happens if you do.

When to call a licensed pro

Chimney work is pro-only: it involves roof access, and a missed defect can mean a chimney fire or carbon monoxide in the house. Hire a CSIA-certified sweep for the yearly inspection and cleaning. When the report recommends repairs, get written quotes from licensed contractors, check each licence with DPOR, and compare them using what chimney sweeping costs in Virginia as a guide to what drives the price.
