What we fix on a slider
- Flat or cracked bottom wheels replaced with a matching roller assembly
- Panel height and level set with the adjustment screws
- Debris cleared from the sill channel and weep holes opened so rain drains out
- Mortise latches, pulls and keepers replaced and lined up
- Top guides and stops checked so the panel cannot lift out
- Screen panels rewheeled, rescreened or squared up
Sliders added to older San Gabriel houses
The city’s Historic Resources Survey describes neighborhoods built mostly from the 1920s through the 1950s, in Period Revival, Minimal Traditional and Ranch styles. None of those were designed with a sliding glass wall. Where you find one today, it was cut in later, often into a stucco or wood wall with a header that has settled a little since.
That history matters for the repair. A slider set in an opening that has moved can rub at the top, drift open, or refuse to latch even with new wheels. We check the frame for square before blaming the rollers, and adjust the panel to suit the opening it lives in.
Rain is the other San Gabriel concern. When the sill channel is packed with leaves, water backs up during a winter storm and can wet the floor inside. Opening the weep slots is a small step that saves a lot of trouble.
Step by step
Look and listen
We run the panel open and closed, listen for grinding, and sight along the bottom rail to see where it drops.
Take the panel off
The stops come off, the panel tilts out and lies flat on padding so we can reach the wheel housings.
Replace and clean
Old wheels come out, matching ones go in, and the sill channel and weep slots are cleaned while the panel is off.
Rehang and tune
The panel goes back up, the height is tuned for an even gap, and the latch is set to catch with a light push.
When it goes to a glass shop
Fogged or broken dual-pane glass, a warped frame, or a whole new door is a glass shop or installer job. We say so after the first look so you do not pay twice.
What to text
A video of the door moving, photos of the latch side and the bottom rail, and the brand label if there is one on the frame edge.
Sliding door questions
Can you add a lock to a slider?
Yes, a foot lock or a bar in the track adds security without changing the door.
Do you replace the handle set?
Yes, if a matching pull and latch are available for the frame.
Why does my door drift open on its own?
The panel is usually higher on one end, or the track slopes. Leveling the panel normally stops it.
My door leaks in the rain. Can you help?
Often yes: clogged weep slots and worn bottom seals are common causes and both are repairable.
Can wood-framed sliders be repaired?
Yes, if the wood is sound. Rotted bottom rails may need a carpenter or a new door.
Is it the rollers or the track?
A dented track makes the door bump at one spot; worn rollers make it drag the whole way. Sometimes both.
Can you fix the screen door too?
Yes, wheels, latch and mesh can all be done on the same visit.
How do I keep it gliding?
Vacuum the channel monthly and wipe it with a damp cloth. Skip oil and grease.
