Common questions about business insurance for door and window installation contractors
Review answers to frequently asked questions about door and window installation business insurance policies and more.
Do door and window installers need a license or certification?
Many states require window and door installation companies to acquire the appropriate certifications for the services and products they offer (such as residential, commercial, impact, rolling steel, etc.), as well as their business license. Additionally, local governments at the county or city level might have their own requirements.
Even when not required, pursuing certifications or a business license can be extremely beneficial to a door and window installation company.
Being a licensed and certified contractor can help you stand out from the competition, gain client trust, and acquire contracts for larger jobs. It shows you've mastered the skills to perform the installation competently and do a good job.
Does installation floater insurance protect door and window installation equipment?
Typically, a standard commercial property insurance policy will not cover items brought to jobsites. This means your door and window installation business will likely need installation floater insurance.
This policy provides coverage for door and window install materials and products—such as doors, windows, moisture barrier, and nails—during the installation process. It also protects them while they're in transit or stored off-site.
Installation floater coverage can help pay for the repair or replacement of business materials that are damaged by vandalism, fire, or a storm. This type of inland marine coverage provides crucial protection for installers who work at their clients' homes, offices, and construction sites.
What other insurance policies do door and window installers need?
General liability insurance or workers' compensation insurance provide crucial financial protection against common risks and work-related injuries, but don't cover all perils a door and window installation professional may face.
Door and window businesses, including sole proprietors and independent contractors, should also consider the following types of coverage:
Builder's risk insurance protects window and door installers and other construction contractors who are working at a structure under construction, along with their materials. It's sometimes called course of construction insurance.
Commercial umbrella insurance boosts the coverage of your general liability, commercial auto, and employer's liability insurance once the policy limit is reached.
Products-completed operations coverage provides protection against lawsuits alleging your completed door or window installation damaged a client's property or caused them an injury.
