Patio doors- deforming in heat - not shutting?

Wooden doors i can understand, not so much PVC

PVC shouldn’t do that, not that I’ve ever experienced. PVC doors are known to sag which would cause this issue, maybe the hinges just need adjusting.

Where I lived previously the patio doors were pvc and they used to expand so much in the sun that they were difficult to close.

PVC has a much greater coefficient of thermal expansion (it expands more) than steel :- engineeringtoolbox.com/the…tml

What colour are the doors ? As you should not use dark doors sloth facing

Mine happens every few years and I have to call the company out to fix it. I could take out their maintenance contract but it’s too expensive so have to fork out around £65 per visit. Would love to see how to fix it. It’s normally the lock that they have to fix as I pull the door hard for it to close. The lock then goes.

Depends on if they're indirect sunlight. My grp front door expands when hot and becomes tighter but this is normal . Would depend on if you have to lift the doors to shut I guess.

How old are they?
Did you pay by credit card?
Is the firm still in business?

French doors or patio doors? French doors have probably dropped so need re ‘toe and heeling’ or there are Allen key adjustments on side top and bottom. Bottom lifts the door. Side Allen key moves it left and right. Probably 4or 5mm Allen key.
Patio doors have screws at the very bottom or both sides. Get a long Phillips and turn. One way will lift the other way will lower. They probably need to go up.

Two different companies, the first was a back door leading into the garden. We had to call emergency services at 1am on home insurance to get the door fixed.

I wasn't clear what the engineer did, but he did say this is a frequent issue in the heat when the doors are left open. (Door was left open all day in blazing heat of ~30℃ + last summer)

The second time, now, it's a totally different house, porch door left partially open about 27℃ for about 5hrs. Now a metal ribbon has loosened and won't close. Perhaps two different issues coincidentally.

Hi, ccnp, age unsure as the previous vendor installed them.

Direct sunlight I'm afraid, we've never had to lift the doors to shut them before..

Does this occur due to heat, or is it a lock related issue?

I recall the engineer who came out referred to the hinges, and he worked on them for a good hour, maybe this is what occurs in direct heat..grrrr wish I'd taken notes when he came round

No heat. I have French PVC doors so they “expand “ so I have to force close them. The doors lock by pushing the handle upwards. So in the summer as the doors have not closed properly I have to get this locked which causes the lock to give over time.

They’re just not locating properly. If you look at the doors from outside whilst they’re closed the gap between the doors should be the same all the way down. I reckon you’ve got a small gap up top and big gap down the bottom. 5mm Allen key on the side of both top hinges and wind them over. Best take a photo of the hinges and put them on here.
