Screen popped out of spline in one spot

I hope I am posting this in the right section.

I've never done screen door repair before but I have seen people do it and I feel it shouldn't be that difficult. However I've only seen people replace the entire screen and not fix just a small portion of it. I recently had part of my screen pop off the spline and I was wondering if there was a way to fix just the portion that is messed up.

Here is a picture of what I am talking about:


As you can see there is a clear area that came undone. Is there a way to reattach the screen to the spline without having to replace the screen on the entire door? Would it as simple as popping out the spline in that one area and trying to push the screen back in? Would there even be enough slack in the screen to do such a thing?

Thanks in advance for any help or tips you may have. I'm hoping I don't have to have the entire screen replaced.

 

You will need a spline roller and a dental pick to pull the old spline out... assuming it is still pliable and can be reused. If the screen is torn (which is what happens most often) that entire side of the screen (including top and bottom) would need to be stretched and rolled in. If its aluminum, it won't stretch. If its fiberglass, it might.

 

I don't try to re-seat screen that has come loose. It's a surprisingly difficult and fussy job to save a few dollars worth of screen.

Since most homes contain many screened windows owning a roller is not a big expense (less than $10). And, if you buy the screen in larger rolls it's even less expensive. Usually the spline can be reused though it seems to grow in length but all you have to do is trim off the extra after you finish.

If reusing spline it helps to clean the old. It even helps if you lubricate it with something like WD-40. Spray it on a rag and wipe down the spline. It helps remove dirt and lubricates it making it easier to push into the slots of the frame.

 

I couldn't find my spline roller the other day and needed to replace an entire sliding glass door screen for a client. I bought this on a lark and will NEVER go back to a standard roller. It allows you to feed the spline at the same time as pressing it in. Made a 30 minute job into a 15 minute job easily. I'd likewise replace the entire screen, mainly because, as Brant and Dane mentioned, your spline may not be pliable enough to be reseated.

Try it, you've got nothing to lose as long as you can get enough screen into the groove. If it doesn't work then replace the screen and be sure that the spline is a good fit.

 

It kind of looks like it was cut to me... when you zoom in on it anyway. When the spline was originally rolled it, it's pretty easy to accidentally score the screen as you roll the spline in.

 

I do this nearly everyday at work. If the screen was loose to begin with, you might be able to have enough screen to stretch into the groove, but it's unlikely. Have it re screened and make sure you have the correct size spline. There are many sizes. You want one that you can just nearly squeeze into the groove with your thumb without screen. Then when the screen is installed you will need to stretch the spline just enough to force it into the groove with the tool.
If you have the thin type frame then you need a jig to prevent the screen from warping the frame as you stretch the screen around the frame. If you have heavy duty frame you won't need to worry about warping the frame. You do not want the screen to be so tight that the screen twist and will not lay flat.
