What each kind of screen and storm door lock really does, how to find a replacement handle that fits, and when the money belongs on the front door instead.
No, a screen door lock won't stop a break-in. It holds the door shut in the wind, keeps toddlers and dogs where you left them, and nudges a try-the-handle opportunist toward someone else's house, but anyone determined gets past it faster than you can find your keys. The lock that actually protects your home is the deadbolt on the entry door behind it.
Picture the classic. A storm door on an older house above West Beach bangs against its frame like a drum every time the wind comes up off Semiahmoo Bay, until someone fits a lock just to get a night's sleep. That's a perfectly good reason to lock a screen door. Keeping out a burglar isn't.
Even the makers say so. Ideal Security describes its keyed storm door deadbolt as a secondary layer of security rather than a high-security lock, and the screen company RiteScreen points out that ordinary aluminum or fibreglass mesh cuts easily.
What a screen door lock is genuinely good at: holding the door shut in wind, keeping small kids and pets in while the main door is open for the breeze, and making a quick try-the-handle visitor move on. The limit is structural. The latch lands in a strike on the storm door's own frame, which is screwed to the trim around your entry door, so the whole thing is only as strong as that strip and its screws.
Five kinds cover almost every screen and storm door around here, from wooden screen doors on older cottages near Crescent Beach and Ocean Park to aluminum full-view doors on newer townhomes.
A pull handle outside with a push button, and a latch inside with a little tie-down lever that locks the button. Wright Products' V333 push-button latch is the textbook version, mounted through three 5/16 in. holes on out-swinging doors 3/4 to 1-1/4 in. thick, with a no-lock-out feature so a tie-down flipped by accident doesn't strand you on the step. Great for wind and kids; no help when you leave, because there's no key.
The same idea with a key cylinder in the outside handle. Wright's keyed tie-down handle fits doors 3/4 to 2 in. thick. Mortise handle sets go further: the lock body sits in a slot cut into the door edge, and Andersen's parts store sells its sets by door thickness, 1-1/4 or 1-1/2 in., for its aluminum storm doors made after 2004.
Plenty of storm doors now ship with the deadbolt in the handle set. Andersen lists a built-in keyed deadbolt on its 10 Series full-view and 6 Series retractable-screen doors, Larson's QuickFit installation sheet fits the handles around a lock body with its own deadbolt and key cylinder, and Wright's Serenade mortise lever set for wood-core storm doors has one too. Before you feel too smug, remember that the bolt throws into the storm door's own latch rail, not your house framing.
The screen on a slider usually has a pull with a small hook latch that catches a keeper on the frame, rarely with a key. It keeps the cat in and stops the screen drifting open. Most sliding screens are also built to lift out of their track for cleaning, which tells you how much a latch on one can hold; the glass door behind it carries the real lock.
The wooden screen door with a spring and a hook is a cottage classic. A hook and eye holds the door against wind and holds a dog in, but it lifts with a butter knife slipped through the mesh, so treat it as a latch, not a lock. If the eye keeps pulling out of soft old wood, move it to fresh wood or use a longer screw.
Most replacement grief starts in the hardware aisle, holding a handle that doesn't match the holes or the thickness of the door at home. Find the label and take two measurements first; the job itself is usually a screwdriver and twenty minutes.
Open the door and look along the hinge side. Pella says its storm door label may be on the hinge side of the mounting frame or on the inside edge of the door between the hinges. Larson's door identification form puts the sticker on the door edge or hinge-side Z-bar for doors made from 1997 on, and asks what name is stamped on the plate where the latch and deadbolt come out, which is often the fastest answer of all. No label? Photograph both handles and the door edge.
Hole spacing is the centre-to-centre distance between the mounting holes, and Wright's standard push-button latch uses 1-3/4 in. Door thickness sets screw and spindle length: the V333 covers 3/4 to 1-1/4 in., the keyed VK444 3/4 to 2 in., and Ideal's SK703 deadbolt 1 to 2-1/8 in. Larson's form lists storm doors from 1 in. to 1-7/8 in. thick depending on the frame, so measure the door, not the old handle. Mortise sets also need the factory-cut slot and are usually brand and series specific.
A toddler who has figured out push buttons is a toddler with an exit strategy. The simplest fix is a hook and eye or a slide bolt mounted high on the inside. To lock from outside as well, Ideal says its SK703 keyed deadbolt can go above or below the existing handle on an out-swinging storm door, as long as the inside part clears the other hardware. Keep anything you add easy for an adult to open fast in the dark.
A storm door handle lives outdoors full time, and in White Rock that means sea air for the houses along Marine Drive and the streets climbing up from East and West Beach. ISO 9223, the international standard for how corrosive outdoor air is, names airborne salinity as a key factor alongside temperature, humidity and sulphur dioxide. Its first-year corrosion rate for zinc runs from 0.7 to 2.1 micrometres in a medium C3 atmosphere and from 4.2 to 8.4 in a very high C5 one.
The standard doesn't hand out categories by postal code; a site gets one by measuring. As a practical rule, the Australian Stainless Steel Development Association (ASSDA) says coastal staining on stainless steel is most common within about 5 km of surf and 1 km of calm salt water. Semiahmoo Bay is calm water, and that 1 km band still takes in the whole waterfront and a good slice of the hill.
And Andersen's storm door warranty covers hardware finish and lockset mechanics for a limited period but excludes damage from airborne pollutants such as salt. A pitted handle on a beach house is usually your problem, not the manufacturer's.
Cosmetic stuff can wait. A latch that won't catch or a key that won't turn is the one to fix before it quits with you on the wrong side of it.
Plenty of storm door hardware is die-cast zinc under paint or a coating; Ideal's SK703 is one example. The coating does the work, so a chip near the water is where trouble starts. Stainless is the upgrade, but grade matters: ASSDA recommends grade 316 or equivalent as a minimum within 5 km of surf. Solid brass won't rust, though it darkens and spots, and a brass-coloured finish is only as good as its coating. Whatever the metal, wash it. ASSDA's rule for stainless is to clean it when the windows need cleaning, without bleach or chloride cleaners, and a handle sheltered under a porch roof never gets the rain's free rinse.
If you want a screen's airflow with something much closer to real resistance, that's what a security screen door is for.
Australia writes it into a standard. Under AS 5039, a screen has to pass knife shear, jemmy, probe, pull, impact and corrosion tests to be called a security screen, according to the National Security Screen Association, which also expects a three-point lock as standard, a key cylinder with at least five pins, reinforced corners and a label. RiteScreen lists the same ingredients: stainless steel mesh, welded corners, several locking points and screws that reach structural framing rather than trim. No lock fitted to a regular screen door can add any of that.
For most homes, the money does more on the main door. A deadbolt that throws fully into a solid strike, held with long screws into the framing, is what a break-in actually has to beat; a security screen in front of a tired entry door is a lovely gate on a broken fence. If the deadbolt needs a lift to throw, the strike is screwed only into trim, or you don't know who else has a key, a lock change or rekey or some door repair comes first.
Much of this is honest DIY: Ideal says its add-on deadbolt installs in about 20 minutes with three drilled holes. A residential locksmith earns the call when a mortise lock body has failed with no label to identify it, when you want the storm door on the same key as the front door, when the storm door has sagged and the latch no longer catches, or when screws have seized in an aluminum frame near the water.
Typical Metro Vancouver ranges for a mobile visit run $160 to $380 for handle set and latch replacement, $75 to $140 for relocating or upgrading a strike, and $80 to $150 for hinge work and realignment. Surface-mount versus mortise hardware, common versus brand-specific parts, keying to match another lock and seized fasteners decide where a job lands. Torn mesh, bent frames and a slamming closer are screen shop or door installer work.

You need a keyed handle or a keyed add-on deadbolt, because a plain push-button handle only locks from inside. Swap in a keyed handle with the same hole spacing and thickness range, or add a surface-mount keyed deadbolt beside the existing handle. Most sliding screens can't be locked from outside at all, so lock the glass door.
Yes. Many storm doors come with one in the handle set, and add-on keyed deadbolts such as Ideal's SK703 mount through three holes on out-swinging storm doors 1 to 2-1/8 in. thick. It's a second lock rather than house-grade security, because the bolt lands in the storm door's own frame.
No. Surface-mount push-button handles come closest, since many use 1-3/4 in. hole spacing, but door thickness still decides fit, and mortise sets are usually brand and series specific. Find the label or the name stamped on the lock plate, and measure, before you buy.
Yes. A residential locksmith can replace or rekey a storm door handle set, fit a keyed deadbolt, reset the strike on a sagging storm door and free seized screws. Torn mesh and bent frames belong to a screen shop, and a good locksmith will say so on the phone.
