roof lining post fit issues?

I'm getting a replacement roof lining and A pillar trims replaced on my Passat Sport by a windscreen company and wondered if I'm likely to experience and issues after.

I hate rattles and squeaks so am apprehensive.

The managed to get the black adhesive all over the head lining and trims which I cleaned what I could off but once it set there was no removing it.

Crazy price as well which luckily I'm not having to pay,

£270 parts and £410 labour plus courtesy car fee.

I'm not sure how they'll get the new lining into the car without creasing it with it being a saloon with a fairly narrow boot and all the glass being in place.

At least if they make a hash of it it's up to them to replace it.
