Most people do not think about a window screen until a bug is loose in the kitchen at 10 at night. By then the screen has been failing for a while. If you spot the signs, a rescreen is a small job. Wait, and a torn screen turns into a bent frame or a summer of swatting. Here is what I look for, and what should get you to pick up the phone.
You can see the hole or tear
This one is not subtle. A tear in the mesh, a hole where a branch or a dog got through, a corner pulling loose. Bugs do not need much. A gap the size of a pencil eraser lets in gnats and mosquitoes all night. If you can see light through a spot that should be solid mesh, the window screen has stopped doing its job.
Bugs get in with the screens closed
You keep the windows open, the screens are in, and bugs get to you anyway. Sometimes the tear is small and sits low, where you do not look. Sometimes the mesh has pulled away from the frame and left a gap along the edge. Berks County hands us mosquitoes, gnats, stink bugs, and now spotted lanternfly. A sound window screen keeps all of them out. A worn one waves them through.
The mesh sags or bows
Fresh screen sits flat and tight. Over time, sun and heat loosen the spline that holds the mesh in the frame, and the screen starts to sag or bow out in the middle. A loose screen tears with the next gust or the next elbow. When I rescreen, I set the tension so the mesh sits drum-tight and stays that way.
The frame is bent, chalky, or corroded
The mesh is half the window screen. The frame is the other half. Aluminum frames bend after a screen gets popped in and out a hundred times, and they corrode after years of weather. If the frame is chalky white, pitted, or bent so it will not sit in the track, new mesh alone will not hold. I straighten frames when I can and rebuild them when I cannot. Pricing for both sits on the window screen repair pricing page.
The screen door drags, sticks, or will not latch
A window screen door has moving parts. Rollers, tracks, a handle, a latch. When it drags on the track, jumps off, or will not close on its own, one of those parts has worn out. I carry rollers and common parts in the van and fix most doors on the visit. See window screen door repair.
The mesh is brittle and crumbles
Old fiberglass mesh goes brittle after enough summers. Push on it and it cracks or flakes instead of flexing. Once mesh is brittle, patching is a waste. It needs a full rescreen. If you want the new mesh to outlast the old, ask me about pet-resistant or aluminum, which take the sun better.
Fix it or wait?
One small tear, caught before bug season, is a fast rescreen and a small bill. The same screen left alone through July becomes a bent frame, a house full of bugs, and a bigger job. If you see any of the signs above, get a price. The call is free, and you decide from there. If you are on the fence between a patch and a rebuild, the repair versus replacement breakdown lays out the math.
