Renewal or rebid: what happens to Illinois cleaning contract prices when the term ends

Six Illinois custodial contracts show what happens at the end of a term: prices locked in years ahead, long extensions, and incumbents who held, raised or lost.

Most public cleaning contracts in Illinois don't end on schedule. They get renewed, extended, or bid again, and each path does something different to the price. We went through the agency records for 6 Illinois custodial contracts where we can see what happened when the term ran out.

Renewals: often priced years in advance

Many bid forms ask for renewal-year prices up front. That means the "renewal" was really decided at the original bid opening.

The City of Darien bid cleaning for City Hall, the police department and public works in 2021. The winning bid already priced its renewal years, rising about 4.7%, then 4.5%, then 4.3% a year. The original RFP allowed renewals only through 2025. In August 2026 the city council approved a sixth year anyway, about 4% above the fifth year and about 24% above the 2021 year-one price.

Extensions can run for years without a rebid

Community Consolidated School District 46 in Grayslake last bid custodial work in 2021. Six companies bid, and the highest year-one price was about 1.4 times the lowest. The agreement ran to June 2024, then went year to year. Amendment #6, signed in October 2026, extends it to June 30, 2027 at a monthly price that works out to about 60% more per year than the 2021 winning bid.

We are not calling that a 60% increase. Earlier amendments we have not seen may have changed the scope, and the current price already reflects a staffing cut tied to an office closure. The practical point: by mid-2027, a contract bid in 2021 will have run six years, and nobody else has had a chance to price it since.

Rebids: hold, raise, or lose

When contracts do go back out to bid, the incumbent's results vary:

• Held the price exactly. Lake Land College's Effingham center was cleaned month to month in 2025. When the college bid it again in August 2026, the incumbent submitted exactly the monthly price it had been paid, for both the three-floor and two-floor options. The college later chose not to pursue a 2026 contract.
• Raised the price and kept the job. North Shore School District 112 rebid in 2024 and drew nine bids. The incumbent won with about a 7.9% cost increase, according to district records.
• Lost to a lower bid. Lisle Library District drew 10 bids in May 2026. The incumbent lost to a bid about 5.5% lower than its own.

A rebid doesn't always change what the agency spends. The Arlington Heights Park District combined work that two contractors had been doing into one 2026 bid. The new contract, base plus alternates, came to about 0.6% more than the district had been spending.

How bidders price the later years

When the bid form asks for multi-year prices, bidders take different approaches. In the three contracts above where later-year prices were read in the documents:

• Arlington Heights Park District (2026, 7 bidders): the winning bid stayed flat for all four years. Others ranged from flat to 2% or 3% a year, and two added about 5% only in years 3 and 4.
• Lisle Library District (2026, 10 bidders): four bidders that listed later years added 3% a year. The lowest bid stayed flat.
• City of Darien (2021, 6 priced bidders): one bid stayed flat, others added about 1.8% or 3% a year, and the winning bid rose about 4.7% in year two.

Those later-year numbers matter. On a contract that gets extended past its original term, they shape what the agency pays for years.

What to watch for

• Whether the bid form locks in renewal prices, and for how many years.
• How many renewals the original contract allows, and whether the board has already used them.
• Short bridge extensions or amendments, which often mean a rebid is coming.
• Scope changes in amendments, which make old and new prices hard to compare.

Where these numbers come from

Every figure comes from the agency's own bid tabulation, board packet, contract amendment or records-request response, for 6 contracts: City of Darien, Community Consolidated School District 46, Lake Land College, North Shore School District 112, Lisle Library District and Arlington Heights Park District. Percentages are calculated from the prices in those documents; annual figures use monthly prices times 12 where the agency quoted a monthly price.

Figures are from public records available as of October 30, 2026. Newer bids may have been awarded since; subscribers get every new result.
