Window Screen Cleaning Service

Why this matters

Screen cleaning is often offered as an add-on service to window cleaning at a modest per screen. For a typical residential 12-window job, that adds a modest to a moderate window cleaning bill - a meaningful margin boost. The challenge: screens are fragile (especially older aluminum frames and torn fiberglass mesh), customer-sensitive (visible damage is the customer's complaint), and add time. A contractor who handles screens cleanly and quickly captures the add-on revenue; one who damages screens or skips them altogether leaves money on the table.

When to offer

• Always offer screen cleaning as part of a window cleaning quote
• Customers may decline (some prefer to keep screens off during cleaning anyway)
• Recommended frequency: same as window cleaning (typically 1 to 2 times per year residential)

Screen types

Procedure for standard residential screens

Step 1: Remove the screen

• Locate the screen tabs (usually on the inside)
• Compress the tabs and tilt the screen out
• Place screens in a stack with care

Step 2: Brush off loose debris

• Use a soft brush to remove visible dust and dirt
• Tap gently on a clean surface to dislodge fine dust
• Avoid using compressed air (can tear old mesh)

Step 3: Wet clean

Method A - Hose down:

• Place screens on a clean grassy area
• Spray with hose at moderate pressure (not power-washer pressure)
• Allow water to flow through the mesh

Method B - Bucket clean:

• Bucket of mild soapy water (dish soap diluted)
• Sponge or soft brush
• Wash both sides
• Rinse with clean water

Method C - Pressure washer (with caution):

• Low pressure setting only (under 800 PSI)
• Hold nozzle 3 to 4 feet from screen
• Move quickly across the surface
• Damage risk: high; only use on sturdy newer screens

Step 4: Dry

• Allow screens to air dry in vertical position (lean against fence or wall)
• 30 to 60 minutes typical
• Don't reinstall wet (risk of moisture intrusion at window seal)

Step 5: Reinstall

• Place each screen back in its original window (track screens during cleaning)
• Verify tabs lock securely
• Inspect for any damage during the process

Equipment

• Soft-bristle brush
• Garden hose with adjustable nozzle
• Bucket
• Dish soap (mild)
• Sponges or microfiber cloths
• Replacement spline (for re-screening damaged screens)
• Spline tool (for re-installing spline)
• Replacement mesh

When screens need more than cleaning

Some screens need replacement or repair:

Torn mesh

If mesh is torn, replacement is the only fix:

• Remove old mesh (cut along the spline groove)
• Cut new mesh to size (slightly larger than the opening)
• Press new mesh into spline groove
• Insert new spline with the spline tool
• Trim excess mesh

Cost: a modest in materials per screen; 20 to 30 minutes labor.

Bent frame

Aluminum frames bend with age or rough handling:

• Some can be straightened gently
• Severely bent frames need replacement
• Pre-made screen frames is inexpensive

Mesh fiberglass vs aluminum

Fiberglass mesh:

• Less durable but easier to install
• Damaged by impacts
• Replace every 5 to 10 years

Aluminum mesh:

• More durable
• Conducts electricity (avoid in some environments)
• Lasts 10 to 20+ years
• Slightly more expensive

For replacement work, ask the customer which they prefer. Fiberglass is cheaper; aluminum is longer-lasting.

Common screen issues

Pet damage

Pets often damage screens (claws on cats, dogs jumping). Replacement is the only fix; pet-resistant mesh exists (heavier weave) at higher cost.

Storm damage

Wind-driven debris damages screens. Storm screens are heavier-duty options for high-wind areas.

Insect damage

Some insects can damage mesh; replacement when significant.

UV degradation

Old fiberglass mesh degrades with UV; becomes brittle. Replace when significant.

Frame corrosion

Coastal areas: aluminum frames corrode. Replacement at end of life.

Customer communication

Set expectations:

• "We'll clean all your screens as part of the service"
• "If we find any damaged ones, we'll let you know; we can repair on the spot or you can schedule a separate visit"
• "Screen cleaning adds $X to today's visit"

Document the screen condition before cleaning:

• Pre-existing tears, frame damage, bent frames
• Photograph if customer is concerned about responsibility for damage

Specialty screens

Roll-up screens (some commercial)

• Disassemble per manufacturer
• Clean the panels separately
• Reassemble carefully

Solar shades

• Wipe down with damp cloth
• Avoid soaking
• Per manufacturer instructions

Magnetic screens

• Easy removal; standard cleaning
• Verify magnets in good condition for reinstallation

Storm windows / storm doors

• Disassemble to access screen
• Clean both screen and glass panes
• Reassemble carefully

Common screen cleaning mistakes

• Pressure washing aluminum mesh: bends or breaks mesh
• Forgetting to track which screen goes where: customer's living room screen ends up in the kitchen window (different sizes don't fit)
• Not drying before reinstall: moisture damages the window track
• Tearing mesh during removal: rough handling
• Not communicating cost upfront: customer surprised by invoice
• Skipping documentation of pre-existing damage: customer blames the cleaner for old damage
