Putting in replacement windows is a great way to improve a home's looks and its energy efficiency. If you haven't handled this type of project before, it's a good idea to make a checklist of preparations. That applies even if you're hiring licensed contractors to do the work. Fill out this checklist to ensure your effort will go off without a hitch.

Permits

If you're just installing replacement windows, the odds you'll need to get permits are pretty low. Generally, permits are only required when you're adding a new hole to the outside walls of the house or if the footprint of the building will be altered. Still, it's wise to contact your local code enforcement office to inquire about what the rules are where you live.

Time Requirements

Count all the windows you plan to replace, and assume each one will take at least 30 minutes. If you're dealing with custom work that requires changing the openings where the windows go, this figure can go as high as 1.5 to 4.5 hours per window. Extremely aggressive projects may take a couple of days per window if you're dealing with large and mechanically complex windows that require significant modifications to the walls.

Add 15 minutes for dealing with the contract and paying the company. You should also plan to have at least one other day to invite the installers over in case of bad weather or if the job proves to be more complicated than expected.

Avoiding Damage to Your Property

There is going to be a lot of equipment in use, and materials are going to be hauled in and out of your house. Put more simply, stuffs going to get banged around. It's a good idea to take down anything that's hanging in your home before starting work. Look around for items like picture frames and glassware. Pack them up like you're planning to move, or at least put them on blankets to protect them.

You may also want to set out a walkway for contractors to get in and out of the house. If you're worried about them tracking in dirt, put down a long rubber mat or a piece of scrap carpet.

Customers should also move outdoor items, such as vehicles and furniture, away from the path of the installation team. Not only does this reduce the risk to your property, but it eliminates stuff the installers will have to move once they arrive.
