Get You Measurements Before Removing Your Windows

If you are replacing very old windows, there are any number of things you might find. I'll try to give you some helpful insight on the basics. It's a good idea to have your window rep work with you on measuring what size windows you will need to replace your current ones. There are a lot of factors that you must be familiar with when measuring and selecting sizes. And you don't want to remove the window, just so you can measure the opening and then order your new windows.

Tearing out your Old Windows

Once you've received your new windows, you need to get a few supplies and you're ready to tear out the old windows.

Items to have handy:

• Insulation
• Long screws (sometimes these come with the New Windows)
• Wood Shims
• Caulkgun and 100% Silicon
• Roofing Felt (if you will be flashing the window)
• Cordless Drill/Driver with Phillips bit and drills
• Prybar/Flat Bar
• Hammer
• Dikes (Angle cutters)

The last three will be used in the removal phase. You might also want a pair of gloves and safety glasses while you're tearing out.

Where to Start

Decide whether you are going to re-use the existing trim inside the house. If you are, you must be very careful in removing it. If it is very old and is a hardwood, like oak, it will be very dry and brittle. Not that it will fall apart, it is still good wood, but it will crack easily under stress. Start at the top and slide your flat bar in between the trim and the wall. Carefully pry up just a bit and slide down 6-8". Don't try to pry too much in one spot, or you'll break it. Continue down the piece until you have it fairly lose, and then all of a sudden it will fall off, so be careful, it will likely have nails sticking out of it.

If it is painted wood, you can also try to find the nail holes and use a nail set to sink them in deep. This will help you because the nail usually pulls through thinner wood.

Remove Sashes

This is going to depend on what type of windows you have. If it's possible, it's generally best to remove the sashes. Some windows though will be fixed and not removable. Some won't come out until you break the frame. This is a tough call and takes lots of experience to know the most efficient course. If you take some thought though, you'll be able to get the job done. And be careful, you are dealing with glass. Unless the sashes come out fairly easily, you will probably break some glass. Don't be alarmed. Be sure to wear proper eye protection and gloves. It's a good idea to spread a tarp out on the floor under the window. It helps make cleanup quick and easy.
