Lawn scarification

[Bigbox]

My lawn was scarified this week and it now has a layer of snow on it - any garden experts know if it is doomed or will it still grow back strong and healthy?

Thanks!

It was scarified, aerated and treated. Although there's been snow for a couple of days it's now gone and we've not really had a deep frost so to speak. There is grass but it's quite muddy in patches. Hopefully it's not doomed but I can't understand (well for business reasons I can) why a national provider would do these treatments in Jan/feb

Don't really want to get into who's done the work, was merely enquiring as to the level of damage potentially to the lawn. Hopefully it will recover, it's looking ok at the moment, and like has been said, grass is pretty resilient although it was only laid two years ago and for the first year it really struggled to take until we got these guys in to help us.

In terms of cuttings, there was loads. Probably about six times the amount from a normal mow!!

So they've done it again. It was booked in for next week so I phoned up to cancel the treatments to be told that they had managed to fit it in that fkn day. One day before the frost and two days before the snow. I'm kicking myself for not cancelling this racket when they did it last year - my lawn was poor all summer, it barely grew at all and just looked kind of patchy. Not 'green' whatsoever, more yellowy green.
Lucky for them green tom has no social media presence. I wonder why

Edited to add it was the full treatment - scarification and aeration

Shocking from both sides. Why on Earth did you let them and what are they doing?

This really won't have done the lawn any favours.

I phoned them a week in advance to postpone it and they'd snuck it in early as they were 'in the area'

I will be cancelling it and I will be seeking an explanation in writing as to why they did it a day before frost and snow was forecast - it's not as if this weather has come out of the blue
