Contractors always want one number, and insurance never gives one cleanly. The premium is assembled from your exposure and your history, and while some of it is fixed, a real portion responds to how you classify, manage, and structure your coverage.
What mostly sets the price
The biggest drivers come with the work. Your trade and its hazard level matter most: roofing, excavation, and framing cost far more than low-risk finish trades. Your size, measured by payroll and revenue, scales the premium. Your workers compensation class codes carry trade-specific rates that can be high. And the liability limits your contracts require, often one or two million plus an umbrella, set the rest.
What you can influence
Several drivers respond to you. Your claims history, captured in the workers comp experience modifier, follows you for years, so a strong safety record is one of the best long-term investments in lower premium. Accurate class codes keep you from overpaying on misallocated payroll. Deductible choices trade premium for retained risk. And the structure of the program, bundling, limits, and umbrella placement, affects the total.
The quiet overcharges
The savings we find most often are not from switching carriers. They are from errors: field labor sitting in a higher-rated class code, an experience modifier that was never reviewed, duplicate coverage across overlapping policies, or limits carried over from a smaller version of the business. These are fixable and invisible until someone looks.
What not to do
The tempting mistake is buying the cheapest policy and discovering at claim time that it excluded your core work, residential, height, hot work, or pollution. A low price on a policy that does not cover your operation is the most expensive insurance there is. Price matters, but coverage that actually responds matters more.
A coverage review checks both sides: that you are not overpaying through errors, and that you are not underinsured to save a few dollars.
