A window installation effort is a task that calls for preparation, even if you're having a professional tackle the job. By getting your location ready, you can improve the chances that your project will go off without a hitch.


Before you even pick a contractor, you'll want to take some measurements and ask for quick estimates. Once you've found someone you're comfortable working with, have them come out to your place and perform their own measurements. They can provide a price and make arrangements for an installation day.

Clearing Out

Removing as many indoor items as possible, such as furniture, is a good idea. You should make a point to remove things like mirrors and picture frames from the walls on that side of the house to ensure that they're not knocked down due to vibrations from the window installation process.

It's also wise to clear out the outdoor spaces near a window. If you're dealing with a second-floor window, be aware that the installer will likely need ladders and other equipment to do the job. In cases involving larger windows, this may include a lift or a small crane, so make sure there's room in the yard to accommodate their needs. The less time you spend moving stuff around on installation day, the better your chances will be to get the job done in one shot.


In most municipalities, you will not need a permit if you're only installing a window where an opening in the house already existed. Should there need to be a new hole cut in the structure, then you'll probably require some type of remodeling permit. This is also likely the case if you need to knock out the exterior wall where there already is a window. Regardless of your plans, take the time to speak with local enforcement officials and ask what the rules are.


Setting aside time in your schedule to accommodate a contractor is prudent. You'll need to be there to let them onto your property, and they'll likely want you to sign off on a few documents before getting started. Depending upon the weather forecast, you might also wish to set aside time for a backup day, in case the circumstances prevent the installation from going forward on schedule. On the majority of jobs, replacement of each window should take about 30 minutes once the installers get rolling.
