A lot of contractors say they can install windows, but can they? There are window manufacturing companies that outsource window installation to contractors, and most of the time those contractors are ok. If you want to hire a contractor to install windows you buy from a different company, be sure your contractor ticks off all the boxes for the job.
How Much Experience Does the Contractor Have?
Hundreds of window installations versus thousands of window installations makes a big difference when it comes to experience. If the contractor does windows as a side thing with several other contractor jobs, this contractor might not be the best option. Any contractor that does roofs or concrete more often than windows or doors is not likely the best candidate. That said, don’t completely discount general contractors if a general contractor has done a lot of window installations.
Licensing and Insurance
Never, ever hire a contractor that can’t produce a business license and proof of personal and business insurance. A dropped and falling window could result in some major injuries, and you don’t want an unlicensed and uninsured contractor seeking compensation for injuries on the job from you. That should be the contractor’s responsibility. Always ask for proof of license and proof of insurance, and make sure they are current through the end of your installation project.
The Window Products Installed
Does the contractor have experience installing the windows you have purchased? Some window manufacturers will only back the warranty and guarantee if you use a contractor that is certified as an installer for their window products. Other window companies will back their products only if they are installed exactly as they instruct. Make sure that the contractor you hire is very familiar with the windows you purchased and want installed on your home or your warranty and guarantee could be voided by the window manufacturer.
