Quick answer: Excess and Umbrella coverage typically costs far less per dollar of protection than your underlying General Liability policy, because it only responds after a large, relatively rare loss. Excavation Insurance Group generally sees the first $1 million layer priced lowest per dollar of coverage among the tiers, with cost scaling up more slowly than the coverage amount as you add height to the tower. Exact pricing depends on your underlying limits, claims history, fleet size, and how much exposure your excess carrier is being asked to schedule underneath the layer.
WHY THE FIRST LAYER COSTS MORE PER DOLLAR THAN THE NEXT ONE
Excess and umbrella pricing works on a “layered” basis: the first million dollars of coverage above your underlying policy is priced highest per dollar, because statistically it’s the layer most likely to actually get touched by a large claim. Each additional layer stacked on top gets progressively cheaper per dollar of coverage, since the odds of a loss reaching that high get smaller the further up the tower you go. That’s why moving from $1 million to $2 million in excess coverage usually costs noticeably less than the first million did, even though the coverage amount doubled.
WHAT ACTUALLY MOVES YOUR PRICE
Underwriters price an excess or umbrella layer based on the exposure sitting underneath it, not just a flat rate table. Your underlying GL and Auto limits, your fleet size and equipment values, your prior claims history, and the type of work you bid (municipal and utility-adjacent jobs carry more severe potential claims than residential site work) all factor into where your quote lands. This is exactly why a full coverage review matters before shopping excess coverage: a program with clean underlying limits and a documented claims history typically prices meaningfully better than one assembled piecemeal, layer by layer, without anyone checking how it fits together.
