Key Takeaway
Custom window screens are made to exact dimensions, frame profile, mesh type, and retention hardware so they fit and function where standard off-the-shelf screens cannot. Choosing the right screen means matching five specifications: finished size to the nearest 1/16 inch, frame depth, mesh material, crossbar placement, and hardware. Solar-control mesh can block up to 90% of solar heat gain, while 20×20 no-see-um mesh stops the smallest insects at the cost of some airflow.
Custom window screens are made to match a specific window’s finished dimensions, frame profile, mesh, and retention hardware, which is why they fit where off-the-shelf options don’t. If a torn screen is letting insects into your home, the question is how much needs replacing: re-meshing a sound frame, ordering custom made screens, or replacing the windows.
What Makes Window Screens “Custom Made”?

Custom means more than width and height. New screens must match five specifications:
- Finished dimensions, to the fraction
- Frame profile and depth
- Mesh type and frame materials
- Crossbar placement
- Retention hardware: clips, springs, pull tabs, pins, and tracks
A screen can be exactly the right size and still refuse to stay in the opening.
Repair, New Mesh, Window Screen Replacement, or New Windows?
| Situation | Sensible next step |
|---|---|
| Small hole, frame sound and square | Patch the mesh |
| Frame straight, corners tight, spline channel intact | Rescreen the existing frame |
| Frame bent, corners separating, spline channel damaged | Order custom screens |
| Drafts, water intrusion, windows hard to open or close | Evaluate the whole window |
There’s no universal hole-size rule. Making the call means sorting your openings by frame condition, tear location, mesh tension, visible wear, and whether the result still looks aesthetically pleasing from the street.
How Do You Measure for Custom Screens?

When you still have the original screen
- Handle removal carefully, without flexing the frame.
- Measure outside edge to outside edge, start with width, then height.
- Record measurements to the nearest 1/16 inch, as manufacturer measuring guides specify.
- Take corner readings to ensure accuracy; frames often bow at the center.
- Note frame depth, crossbar location, and every clip, spring, tab, and pin.
When the screen is missing
Identify the window type and screen channel, photograph the tracks and corners, and check the sash for manufacturer markings. Ordering systems differ: some fabricators build to the exact specifications you enter, others expect the opening measurement. Confirm which method applies before you order.
How Do You Choose the Right Mesh and Frame Materials?
Window screen material decides airflow, view, and insect protection, so choose by goal rather than catalog.
| Mesh | Best for | Tradeoff |
|---|---|---|
| Standard fiberglass (18×16 mesh) | Everyday insect protection and airflow | Gives way under claws from pets |
| Aluminum | Rigidity and long lasting durability | Dents and creases permanently |
| Improved visibility mesh | Clearer views, more air | Finer strands in high-contact spots |
| 20×20 no-see-um mesh | Ideal for gnats and other tiny insects | Tighter weave, less airflow |
| Solar-control screen | Filters sunlight to cut heat gain and glare | Darkens the view noticeably |
Do Solar Screens Really Reduce Heat and Glare?

Solar-control screens are a different product from ordinary insect mesh, designed to intercept the sun’s heat before it reaches the glass. The U.S. Department of Energy reports they may block up to 90% of solar heat gain, depending on material. That’s a heat-gain figure, not a utility-bill promise, and the view is noticeably darker.
Why Window Style and Hardware Decide the Fit
- Single hung and double hung: half or full screens on spring-loaded pins or tension clips
- Sliders and patio doors: rollers, tracks, and latches that match the channel
- Casement and awning: interior-mounted, held by clips or turn buttons
A perfectly sized frame with the wrong flange depth will rattle or drop out. Hardware decides functionality as much as fit, and a home with mixed window types rarely takes one standard order.
Where Flexible Mesh and Porch Screen Panels Fall Short
Roll-and-trim mesh kits and cut-to-size porch screen panels can cover a gap for a season. Neither holds tension like a framed screen, and neither keeps insects out for long.
What Window Screens Cannot Do: Safety and Egress
The Consumer Product Safety Commission advises never relying on an insect screen to keep a child from falling out of an open window. It estimated 5,600 children age 12 and under were treated in emergency departments in 2024 after window falls. Window guards and stops that limit openings to 4 inches are the recommended protection; pet-resistant mesh is not.
Screens over emergency escape windows must be removable from inside without a key or tools and must not reduce the required clear opening. Clear-opening figures vary by local adoption, so check your local code.
When New Window Screens Aren’t Enough
Screens do a great job keeping insects out, but they won’t fix drafts, water leakage, deteriorated sills or sashes, or windows that no longer operate properly. ENERGY STAR lists those as reasons to consider an upgrade to replacement windows.
That’s where we come in. One clarification first: we do not offer screen replacement or repair as a standalone service. We provide and install screens only when they come with the new windows we’re installing. We’re a family-owned Anlin Authorized Dealer and James Hardie Alliance Select Contractor serving Northern California, and our experts install each unit to the manufacturer’s specifications. Anlin windows are California-engineered for long lasting performance, with Low-E3 glass for energy savings, sleek BetterVue® screens built into the window system, and a lifetime warranty with accidental breakage coverage that extends to associated screens; restrictions apply. Care is easy: mild soap, water, and a soft brush, no pressure washing.
Frequently Asked Questions
What determines the price of replacement window screens?
Size, frame profile, mesh, hardware, and quantity.
Can I rescreen instead of buying new window screens?
Yes, if the frame is square, the corners are secure, and the spline channel is intact. Rescreening and screen repair aren’t services we offer; our screens come only with new window installations.
When should I replace the windows instead?
Drafts, water leakage, failed operation, or deteriorated sashes point to window replacement.
