One of the many things that needed to be fixed on this house were the window screens. Most of them only had a few small holes. But there were a couple that had such big holes and rips that we couldn't even open those windows because they would let too many bugs in. Luckily, this was an easy and fairly inexpensive project - about $25 to re-screen the entire house.
Roll of Window Screen
1. Your screen will probably be dirty so you may want to lay down an old towel or sheet to keep your floor clean. Remove the old spline. If your screens are as bad as mine, this will already be partially done for you. :) Then remove the old, nasty screen. If you have the time, you may want to go ahead and clean the frame and your windows while you are at it. I did this during a very short break in a heat wave so I skipped that part so I could get right to enjoying the fresh air.
2. Cut your screen so that there is an overhang of an inch on every side.
3. Use the rounded side of the spline roller to push the screen into the groove on one side.
4. Push the new spline in to hold the screen in place.
5. Use the other end of the spline roller (the one that has a groove in it) to push the spline all the way down.
6. Repeat steps 3-5 on each side holding the screen tight while you do so. One site that I visited said to do step 3 all the way around before putting the spline in but when I tried to do that the screen kept coming out of the groove. For me it was easier to put the spline in as I went. You might want to hold your screen up and see if it is tight. If not, you can remove the spline and start over again.
7. Holding your utility knife at an angle, cut off the excess screen getting as close to the spline as you can.
Now you're done! Put your screen back in the window and enjoy the fresh air.
