Commercial Window Cleaning Contracts in Michigan: What to Look For

Why a Written Contract Matters for Commercial Window Cleaning

A handshake agreement or a one-line email confirmation might work for a one-time residential clean. For commercial window cleaning — where you're managing recurring service across a multi-tenant building, a corporate campus, or a portfolio of properties — a written contract is not optional. It defines what gets cleaned, how often, at what price, and who is responsible when something goes wrong. Facilities managers who operate on verbal agreements with vendors frequently discover the gaps when a claim arises, a service gets skipped, or a price increase shows up without notice.

This post covers what a well-structured commercial window cleaning contract should include, what red flags to watch for, and how ClearView Exterior Services structures its commercial service agreements in Michigan.

What a Good Commercial Window Cleaning Contract Includes

Defined Scope of Work

The scope section should answer: exactly which glass surfaces are included? Interior and exterior, or exterior only? Does the contract cover lobby entrances, ground-floor storefronts, upper floors, skylights, partition glass, atrium glazing? What about frames and sills — are they included or extra? A scope that says "all windows" without a detailed surface inventory creates disagreements. A proper scope names every surface category and states what "cleaned" means for each one.

Service Frequency and Scheduling Terms

Commercial contracts should specify whether service is monthly, bimonthly, quarterly, or on a custom schedule, and whether that schedule is calendar-fixed or triggered by a notification process. The contract should also address who is responsible for scheduling access, how much advance notice is required, and what happens if a scheduled visit is missed due to weather, building closure, or other circumstances.

Pricing Structure and Escalation Clauses

The base price per visit or per month should be clearly stated, along with any conditions under which pricing can change. Multi-year contracts should include a defined escalation mechanism — typically tied to a published index like CPI — so that both parties have predictable cost expectations. Watch for contracts that quote a low rate with no escalation language and reserve the right to reprice at any visit.

Insurance Certificate Requirements

This is non-negotiable for any commercial property. Your contract should require the vendor to carry, at minimum: general liability insurance (typically $1 million per occurrence, $2 million aggregate for commercial work), workers' compensation covering all employees and subcontractors, and automobile liability if vehicles are used on-site. The contract should require the vendor to provide a current certificate of insurance naming your organization as an additional insured, and to notify you of any lapse in coverage. Never accept a verbal assurance of insurance — require the certificate before service begins.

Liability Clause and Damage Procedures

The contract should specify what happens if a window is broken, a frame is damaged, or a cleaning chemical causes a surface problem. A fair liability clause holds the vendor responsible for damage caused by their work, establishes a claim notification window (typically 24–48 hours after service), and defines how disputes are resolved. Avoid contracts where the liability clause limits vendor responsibility to a nominal cap unrelated to actual replacement costs.

Cancellation and Termination Terms

Both parties need flexibility. The contract should define how much notice is required to cancel (30 days is standard for commercial service), whether there are early termination penalties on multi-year agreements, and under what conditions either party can terminate for cause without penalty. A vendor who won't allow cancellation with reasonable notice is a vendor who doesn't expect their service to retain clients on its merits.

Red Flags to Avoid

• Verbal agreements only. If a vendor resists putting terms in writing, that is itself the answer about how disputes will be handled.
• No insurance documentation. Any vendor who cannot produce a certificate of insurance should not be on your property. The liability exposure to your organization is not worth the cost savings.
• Undefined scope. "We'll clean all the windows" with no written inventory means you will spend time arguing about what was included after every visit.
• No defined frequency. "We'll come when needed" is not a commercial service agreement. It's a call-us-when-you-complain arrangement.
• No cancellation terms. A contract with no exit provisions locks you into a vendor relationship with no recourse.
