Bonding Letters in Illinois
The Keating Agency writes bonding letters across Illinois. Owners and GCs often ask for a bonding letter before you bid. We issue a clean letter stating your single and aggregate capacity, signed by the surety.
A bonding (or surety) letter confirms that a surety supports your contracting operation and states the single-project and aggregate limits they're comfortable bonding. It's a prequalification tool — not a guarantee of any specific bond — used to satisfy owners, GCs, and bid documents.
In Illinois: IDOT and Illinois public owners often request a bonding letter at prequalification, because the Public Construction Bond Act requires payment and performance bonds on public work. The letter documents your single and aggregate surety capacity for vetting before bid.

Bonding Letters in Illinois — FAQ
Is a bonding letter a guarantee that you'll issue the bond?
No. It states the surety's general support and capacity. Each bond is still issued subject to the usual review, but a letter means your account is already underwritten.
How fast can I get one?
For an underwritten account, often same day. For a new account we need to establish the file first — financials and WIP are the gating items.
What limits will the letter show?
Your single and aggregate capacity as supported by your financials and track record. We work to position the strongest accurate numbers.
