Ask your broker for online access, then issue your own window certificate in about a minute, free, any hour. A certificate of insurance is the one page summary of your policies, limits, and dates, and Morrow clients print their own at no charge. Changes that need an endorsement (a change added to your policy, usually one extra page) still go through the broker. Who this is for: replacement window, entry door, patio door, and storefront installers.
The short version
- Your broker issues certificates. Some let you issue your own online, free, in a minute.
- You work inside people's homes, so damage to floors, alarms, and furniture is a real part of the risk.
- Water getting in around a new window is the claim that shows up long after you are paid.
- Retailer programs and builders want exact wording and a new certificate every policy year.
- Naming a customer on the certificate is fast. Adding them to the policy is a change your broker makes.
How do I issue my own certificate in about a minute?
- Sign in to the certificate tool your broker set up for you.
- Pick the policies the job needs, usually general liability, workers comp, and auto.
- Type in the homeowner, builder, or retailer who asked, with their address.
- Add the job address and the order number if they use one.
- Send it, or upload the file to their portal.
Your coverage does not change when you do this. You are printing proof of what you already bought. See what a certificate of insurance is and how weekend requests work.
Who asks a window and door installer for a certificate?
| Who is asking | What they look at first |
|---|---|
| A homeowner | That you carry liability and workers comp before anyone opens a wall in their house |
| A retailer install program | Their exact limits, their entity name on your policy, and a fresh certificate every year |
| A builder or general contractor | Limits, dates, workers comp, and protection that lasts after the unit is installed |
| A condo board or property manager | The association named correctly, and a certificate on file before work starts in any unit |
| A commercial customer | Higher limits for storefront and entry door work, often with an umbrella listed |
What can go wrong on a window job, and who pays?
Two kinds of loss drive this trade. One happens while you are there. The other shows up seasons later.
| What happens | Typical bill | What usually answers |
|---|---|---|
| A unit is dropped on a hardwood floor | $1,500 to $6,000 | General liability, damage to the customer's property |
| The house is left open overnight and something is stolen | Varies | Sometimes your liability policy, if leaving it open led to the loss, but these claims get argued. The policy pays for physical damage to property, and things simply taken are often disputed. Property you were holding for the customer is left out |
| Glass is broken in the van or on site before install | $400 to $3,000 a unit | Coverage for materials in transit or stored on site, a separate policy line |
| Rain gets in around the new opening the first winter | $4,000 to $30,000 | General liability after the job, called completed operations |
| The unit itself is faulty | Varies | The manufacturer's warranty, not your insurance |
The dollar figures are illustrative and depend on the house, the product, and the state. Most of the money is in water damage and in things you carry through somebody's living room.
What extra lines do customers ask me to show?
Beyond the usual three, two come up in this trade. Coverage for materials in transit and stored on site, sometimes called an installation floater, protects units before they are attached to the building. Larger builders and commercial customers also ask for an umbrella, a second layer of coverage above your other liability policies.
If a contract asks for either one and your certificate is blank there, that is a coverage gap, not a paperwork gap. See what to do when requirements exceed your policy.
What holds up a window and door certificate?
Four things, and three of them are typing. See the common certificate mistakes that delay a job.
- The customer name is not exact. Retail programs and portals match text letter for letter.
- The finished work wording is missing. Builders check this before the limits.
- The customer is on the certificate but not on the policy. Your broker adds them, and many policies do it automatically when a signed contract requires it. That automatic wording normally reaches only the customer you signed with, for work in progress. An owner or a management company above them, and cover that continues after the job, usually take their own changes, so ask your broker which ones you have. See how automatic wording works.
- The policy expired last week. Issue the new certificate the morning your policy year starts.
What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A two crew replacement window company in Massachusetts has 14 custom ordered units delivered and stacked in a condo hallway. The board allows install work only between 9 a.m. and 4 p.m. on a Saturday.
What went wrong: The board will not release the freight elevator without a certificate naming the association. The request comes in at 7 a.m. Saturday, and the office that issues certificates is closed until Monday.
What it cost: The crew lost the Saturday window, roughly $1,800 in revenue, and paid about $400 to store and redeliver the units. Illustrative figures that vary by building.
The fix: A certificate you can issue yourself would have released the elevator in a minute. Ask your broker whether you can issue your own before the next Saturday slot lands.
Frequently asked questions
Q: How can I get a free, instant certificate of insurance for my window and door installation business?
Ask your broker for online certificate access. You fill in the customer and the job address, then send the certificate yourself in about a minute. Morrow clients do this free, at any hour.
Q: Do I need a certificate for a one day homeowner job?
You are rarely required to have one, but sending it wins work. It shows the homeowner that a broken window or a damaged floor is covered by something other than an argument.
Q: What limits do retailer install programs usually want?
Most ask for $1,000,000 for one incident and $2,000,000 for the year, and some ask for $2,000,000 with an umbrella on top. The program packet spells it out.
Q: Are the windows covered while they sit in my van?
Not by general liability. Materials in transit or stored on a job site need their own coverage line, which many installers add for a few hundred dollars a year, an illustrative range that depends on your values.
Q: A window I installed leaked two winters later. Is that covered?
It can be. The policy that answers is the one you carried when the water damage happened, not the one you hold when the customer calls, and it has to cover work you have already finished. Damage to the wall and the floor is the covered part. Replacing your own labor is usually not.
Q: Can I email the same certificate to every customer?
You should not. Each customer should be named on their own, with their own job address. Self service makes that a minute of typing.
Q: My certificate was rejected. What is the usual reason?
A name that does not match the contract, an expired date, a limit below what the program asks for, or wording that was never added to the policy. The first two you fix yourself in a minute.
