Insured vs Uninsured Exterior Cleaners: Why It Matters When Someone's on Your Roof
Exterior cleaning quotes can vary a lot, and one of the biggest hidden reasons is insurance. An uninsured operator has lower overhead and can quote less, but that saving comes by transferring the risk onto you. When the work involves ladders, roofs and high-pressure equipment around your home, that risk is real.
Here is what insurance actually protects and why it is the one thing not to compromise on.

What can go wrong, and who pays
Exterior cleaning is height-and-equipment work. A worker can fall from a ladder or roof, a ladder can go through a window, high pressure can damage siding or force water inside, and equipment can mark or crack a surface. These are not common on a professional job, but they are exactly what insurance exists for.
If the company is uninsured and a worker is injured on your property, or your home is damaged, you can find yourself exposed, potentially through your own home insurance or directly. Hiring insured means the company's coverage answers for its own work and its own people.
The coverage that matters
Two things matter most. Liability insurance covers damage to your property caused by the work. Workers' coverage (WorkSafeBC here) covers injuries to the crew, so an injured worker is handled through that system rather than becoming your problem. A professional company carries both and will show proof without hesitation.
Asking for proof of insurance is completely normal and expected. The only companies that bristle at the question are the ones who cannot answer it, which is precisely the information you are after.

Why the cheapest quote is often uninsured
Insurance is a real cost of running a legitimate exterior cleaning business, along with proper equipment, training and safety gear. A quote that is dramatically lower than the others has to be cutting something, and coverage is one of the easiest things to cut invisibly, until something goes wrong.
It is not about paying the most; it is about not paying the least for the wrong reason. Confirm the company is insured, and the low quotes that were low because they skipped it sort themselves out.
