As a window cleaning service in Denver, you are a vendor on someone else's property every working hour, and that status creates most of your exposure. The building owner's rules, not yours, decide what window cleaning service insurance in Denver has to look like on paper. A dropped tool, a wet entry, a ladder leaned against a neighbor's siding: each becomes a third party claim the moment someone else's property or body is involved. You are also an employer of people who spend the day at height, which prices differently than almost any other cleaning work. Both realities show up in the quote before you say a word about revenue. The sections ahead cover the lines window cleaners carry, the published ranges, and the questions a contract usually forces you to answer.
What Makes Denver Different
Subcontracting a job you cannot reach yourself moves the work, and it does not always move the liability. If you hire another crew for a high rise in Denver, your client still holds you to the contract. Their insurance becomes your problem, because a gap in theirs lands back on your policy and your file. Collecting a certificate from your sub is the same chore your clients perform on you every year. Skipping it is how a one day favor turns into a claim you end up funding personally. The rule is simple: anyone working in your name carries what you would carry yourself. Uninsured subs are also a payroll question, and audits in Colorado find them reliably at year end. Nobody enjoys that paperwork, and the alternative is worse in every direction that matters.
Local Risk Factors in Denver
Hail in Denver breaks the glass you were hired to keep clean, then fills your week with work on damaged buildings. The van takes the first hit: windshield, roof, and the ladders racked on top can all be dented in one storm, and comprehensive coverage under Commercial Auto may answer for the vehicle, subject to your deductible. The poles and tanks inside are a separate question worth asking before the sky turns. After a hail event across Denver County, owners want glass cleaned around fresh replacements, and a crew working beside a glazier's crew is a coordination problem with a claim attached. Damage you cause while working is a liability matter; damage hail already did is not yours to explain, provided you photographed it first.
What Coverage Does a Window Cleaning Service in Denver Need?
General Liability
A dropped scraper that finds a shoulder, a hose that trips a customer, a pole that scars a neighbor's siding: these are the third party claims General Liability is generally built to answer, along with the defense costs behind them. It typically does not reach your own tools, and damage to the very pane you were cleaning can land inside a care, custody, and control exclusion.
Example: A pedestrian walking under a second story ladder in Denver is struck by a falling squeegee and needs stitches; General Liability can help cover the injury claim and the lawyer who arrives with it.
Workers Compensation
Once you put somebody on payroll, this is the line clients, landlords, and state rules expect to see. Workers Compensation is meant for your own crew's injuries: a fall from a ladder, a shoulder worn out by repetitive work, heat sickness on a summer job. It is quoted per hundred dollars of payroll and generally does not respond to anyone who is not your employee.
Example: A window cleaner slips off the third rung and breaks a wrist on a routine storefront call; Workers Compensation may respond to the medical bills and to part of the lost wages.
Commercial Auto
Personal auto forms commonly exclude business use, which leaves a van full of poles, ladders, and tanks outside the only coverage many new owners assume they have. Commercial Auto is designed for that vehicle, for the employees driving it between accounts, and for the harm it can do to other cars and people. Comprehensive coverage on it might reach theft or storm damage, subject to your deductible.
Example: A crew van loaded with extension poles rear-ends a sedan on the way to a morning route; Commercial Auto is generally where the repair bill and the injury claim both get sorted out.
Commercial Umbrella
Your primary lines each stop at their own limit, and a serious claim does not. Commercial Umbrella sits above them and starts where they end, which is the usual way a window cleaning service reaches the limit a large contract names, often for less than raising the primary to the same place. It follows the underlying forms, so it inherits their exclusions rather than filling a gap they left.
Example: A ladder falls in a lobby in Denver and injures three people at once, exhausting the primary limit mid-settlement; a Commercial Umbrella might carry the remainder, subject to its own terms.
How Much Does Window Cleaning Service Insurance Cost in Denver?
Window Cleaning Service Insurance is a bundle of separate policies, priced separately. The ranges below are typical figures for Denver for each line, except workers compensation, which is rated per $100 of payroll; a quote prices each one against your own operations.
| Coverage | Typical range | What moves your price |
|---|---|---|
| General Liability Insurance | $110 - $360 per month | Industry and risk classification, annual revenue, number of employees |
| Workers Compensation Insurance | $0.75 - $2.74 per $100 of payroll | Employee classification codes, total annual payroll, experience modification rate |
| Commercial Auto Insurance | $220 - $575 per month | Fleet size and vehicle types, driver records and experience, coverage limits and deductibles |
| Commercial Umbrella Insurance | $70 - $240 per month | Umbrella limit requested, limits carried on the underlying policies, loss history on those underlying policies |
Prices shown are general estimates, not guaranteed rates or quotes. Your actual premium will depend on the insurer, coverage selected, business details, location, claims history, and other underwriting factors.
What Are the Insurance Requirements for a Window Cleaning Service in Denver?
Workers' comp is generally required once you have your first employee. Colorado generally requires employers to carry workers' compensation at that point. Common exemptions include sole proprietors, partners in partnerships, and members of LLCs. Confirm current thresholds with your state's workers' compensation agency before you hire.
State auto liability minimums apply to business vehicles. Colorado's minimum auto liability limits are $25,000/$50,000/$15,000 (bodily injury per person / per accident / property damage). Contracts and lenders often require more than the state floor.

Operating in Denver
- Subcontracting a high rise job you cannot reach yourself moves the work but not the contract. Your client still holds you, so an uninsured sub becomes a claim you end up funding personally.
- Loss runs follow you across Colorado, and a carrier reading three small glass claims inside one year sees a frequency pattern rather than bad luck.
- Landscaping under a second story window is what people forget: a dropped bucket flattens a shrub bed, and the owner of a Denver property wants it replaced rather than apologized for.
- Renewal is when payroll and vehicle counts get trued up, and the crew member you added midyear is why your number moved before anyone quoted anything.
How to Buy: Advice for Denver Owners
Start with the contract, not the quote. Pull the insurance exhibit from every recurring account you hold in Denver and list what each one demands: limits, additional insured wording, waivers, notice periods. That list is your shopping spec, and it usually asks for more General Liability limit than a new owner would buy on instinct. If the required numbers outrun a primary policy, Commercial Umbrella is the usual way to reach them without rebuilding the whole program. Then look at the vehicle side, because a van packed with poles is rated as a commercial exposure whatever the sign on the door says. The Colorado Division of Insurance publishes consumer guidance on how commercial policies get compared. With the spec written down, you can put one identical submission in front of participating carriers through CPK and see which numbers actually move.
FAQ
Window Cleaning Service Insurance in Denver: FAQ
It sits above them instead. An umbrella follows the underlying lines and begins where they stop, which is why one endorsement can satisfy several contracts at once. It also inherits many of the underlying exclusions, so it does not repair a gap; it extends a limit. Compare the cost of raising the primary against adding an umbrella, because the answer differs by carrier in Colorado.
Price follows a handful of inputs, and the number of windows is not one of them. Payroll, the heights your crew works at, how many vehicles you run, and your claims history do most of the work. A solo operator on storefront glass rates differently than a four person crew on high rise work. The published ranges on this page show where quotes tend to land for a window cleaning service in Denver.
That is a third party property damage claim, and General Liability is generally the line built to answer it. Your client's policy is not designed to pick up damage your crew caused, and the owner of a car parked outside a Denver storefront will look for whoever was up the ladder. Expect to pay your deductible, and expect the claim to sit in your loss history for years.
Usually yes, and many contracts require it. Adding a client means your policy can be asked to defend them when your work causes the loss, which is a real transfer of risk and part of the price of the account. Wording matters here: blanket and scheduled endorsements behave differently, and a certificate naming the wrong one can be rejected at the desk.
Commonly it does not. Personal auto forms typically exclude business use, and a van loaded with ladders, poles, and tanks is business use by any reading. Commercial Auto is the line intended for that vehicle and for employees driving it between accounts. If a crash happens on the way to a job in Denver, which policy applies gets decided by the form, not by intention.
That one is trickier than it looks. Damage to the property you are working on can fall under a care, custody, and control exclusion, meaning a liability policy might not respond to the pane itself even while it responds to everything around it. Ask about that exact scenario on every quote, because the answer moves with the form and it is the loss window cleaners actually have.
