How to Start a Chimney Company in Washington

Wood stoves, gas inserts, and older masonry fireplaces are everywhere in Washington, from Puget Sound bungalows to mountain-town cabins, and most of them need sweeping, repair, or a rebuild eventually. Chimney work pairs steady seasonal demand with real skill, which keeps competition thinner than in trades anyone can pick up overnight. If you know masonry, flues, and fire safety, there is a genuine business here.

What stalls most people is not the chimney work itself, it is the legal path to getting paid for it. Washington requires a specific sequence of registration steps before you can advertise or bid chimney jobs, and chimney work carries a few of its own wrinkles inside that sequence because it touches fire safety and, often, gas appliances. Do the steps out of order and you burn weeks waiting on paperwork, or pay for a bond or policy that does not match what you actually registered as. Most people who look into "starting a chimney business" stall right here, not from lack of skill, but from lack of a clear order.

Here is that order.

The launch roadmap for a chimney company

1. Step 1: Choose a name and a business structure

   You need a company name that is actually available in Washington, and a legal structure, usually a sole proprietorship or an LLC, to run the business under. This decision shapes your taxes and how protected your personal assets are if a job goes wrong, which carries extra weight in a trade involving fire and heat. Confirming availability and picking the structure that fits your situation is a step you handle before anything else.

2. Step 2: Apply for your UBI number and state business license

   Washington issues a 9-digit Unified Business Identifier through the state Business License Application, and it unlocks every step that follows. The base fee runs roughly $50, more if you add certain endorsements, and you need to select the categories that actually match chimney work. Get this wrong or incomplete and everything downstream waits on it.

3. Step 3: Set up your contractor bond at the right amount

   Chimney companies register as a specialty contractor in Washington, which calls for a $15,000 surety bond (general contractors, who run multiple trades on a job, need $30,000). The bond figure is the coverage amount, not your bill. The actual premium you pay each year is far smaller and depends on your credit. People regularly confuse the two, or set up a bond for the wrong registration type, and have to redo it. Match the bond to your actual registration before you commit to one.

4. Step 4: Get liability insurance in place

   Washington sets a floor before you can register: $200,000 public liability and $50,000 property damage, or $250,000 combined single limit. For chimney work, this is not just paperwork. You are working around fire, heat, and often a client's roofline, and a policy that actually fits your risk protects you the day something goes wrong on a rebuild or a sweep. Have the policy and proof of coverage ready before you file for registration.

5. Step 5: File your L&I contractor registration

   With your UBI, bond, and insurance in place, you register through Washington's Department of Labor & Industries. There is a $150.20 fee and the application must be notarized. This is the step that legally allows you to advertise and bid chimney jobs in the state. File it before your UBI or bond documentation is ready and it bounces back, costing you weeks right before the fall rush when everyone suddenly wants their chimney swept before winter.

6. Step 6: Handle the chimney-specific pieces

   Chimney work sits at the intersection of masonry, roofing, and fire safety, and if your work includes installing or servicing gas inserts or gas log sets, that can pull in additional requirements around gas fitting that a straight masonry sweep does not trigger. Working at height on a roofline also brings its own safety expectations the moment you bring on a crew. Knowing exactly which parts of chimney work fall under your registration and which need a separately licensed specialist is something you want locked down before your first job, not after an inspector or an insurance adjuster asks.

7. Step 7: Get your first customers finding you

   Being registered does not mean the phone rings. Homeowners searching for chimney sweeps and repair companies need to find you, and a fully filled-out Google Business Profile, with your service area, phone number, and photos of completed work, is the single highest-leverage free move available. Bing Places is a fast second listing that costs nothing. A simple one-page website with your name, trade, service area, and a quote button beats an expensive custom build, as long as your name, address, and phone number stay consistent everywhere.

That is the full chain, and each link depends on the one before it.

Why most people stall before job one

Every step above is something you can do yourself. What trips people up is the order and the traps hidden in it. Buy a bond before your UBI exists and that move is wasted. Register under the wrong category and your bond amount does not match. Grab a generic liability policy that ignores the fire and roofline risk specific to chimney work. Submit your L&I registration missing one document and lose two or three weeks right as the fall rush starts. Get fully registered and then realize no homeowner can find you because there is no Google Business Profile set up.
