Window Screen Replacement: Mesh, Frames, and Custom Sizing

Screen work is easiest to compare after deciding whether the frame is reusable. A rescreen replaces mesh and spline in an intact frame. A replacement screen supplies a new frame, corners, springs, or manufacturer-specific assembly. Andersen says replacement accessories should be ordered by unit identity or visible-glass measurements and offers both conventional and TruScene mesh on some products (Andersen screen parts).

Measure the part the manufacturer expects

Situation	Measurement or identifier	Bid implication
Branded replacement screen	Window series and unit number	May allow a direct catalog order
No identifier	Visible glass width and height	Helps narrow the manufacturer’s grid
Custom frame	Opening width and height at multiple points	Small errors can prevent fit
Rescreening	Existing frame, spline channel, and corner condition	Labor includes removal and tensioning

Andersen’s custom screen guide instructs taking multiple width measurements, using the smallest measurement, and subtracting the specified allowance. Its model-specific instructions should control over a generic tape-measure formula (Andersen custom screen measuring guide).

Do not measure the old mesh and assume it is the finished screen size. Record the window’s brand, style, visible glass, frame channel, latch or spring locations, and whether the screen is full or half height. Photograph corners and labels before ordering.

If the screen is for a casement, awning, patio door, or specialty window, identify the operating path before choosing a frame. A screen that fits the opening can still block a handle or fail to engage its clips. Ask the provider to confirm the part number, finished outside dimensions, mesh color, and whether installation includes final fit testing.

Mesh is a use decision

Conventional fiberglass mesh may suit ordinary insect control. A tighter or specialty mesh can change airflow, visibility, durability, and price. Andersen lists conventional and TruScene options for certain screen families, but availability is product-specific. If pets, coastal exposure, or high traffic matter, state that need in the quote and ask what mesh is included.

For rescreening, ask whether the frame is straight, whether corner keys are reusable, whether spline is replaced, and whether the finished screen is warranted. A new mesh in a bent frame may look acceptable on the bench and bind in the window. For a manufacturer replacement, ask whether the part includes tabs, springs, clips, and shipping.

Compare quote scope

Separate pickup or mobile service, removal, mesh, spline, frame repair, installation, and disposal. A per-screen number is meaningful only when screens share style, size, mesh, and access. If multiple screens are different, request an itemized list. Screens on upper stories may need interior access or temporary sash removal; that should be stated.

Compare catalog part prices only after confirming the screen identity; a custom frame or mobile rescreening visit covers a different purchase. Frame style, mesh, brand, custom sizing, and service method vary. Use the manufacturer’s measurement system and obtain a written part description before approving the order. Keep the old screen until the replacement fits, unless the provider requires its return.
