Why Is My Sliding Door Harder to Open in Summer?
Summer often exposes rollers and tracks that were already worn. Heat and humidity make the drag more noticeable.
The short answer
Heat and humidity don't usually break a door on their own. They make existing wear more obvious: worn rollers, a grooved track, grit in the rail or a panel that has dropped out of alignment.
Cleaning the track can help for a while. If the door still drags, the rollers or rail usually need attention.
What not to do
Don't force the door or try lifting the panel. Avoid sticky sprays that hold dirt in the track.

What it costs: $99–$375 per panel for standard repairs
On a standard residential sliding glass door, our repairs run $99–$375 per panel depending on the parts and labor involved. The estimate is free and you get the price before any work starts.
Impact doors need an on-site estimate
Impact-rated (hurricane) sliding doors are a different job. The panels are much heavier because of the laminated glass, the rollers and tracks are often brand-specific, and the frames are built to strict Florida code. Two impact doors that look the same can need very different parts and labor.
That's why we don't quote impact doors over the phone. We come out, look at the door, check the brand, the panel weight, the track and the rollers, and then give you an exact price. The on-site estimate is free.
