I went with Peak to Peak a couple years ago after getting quotes from them and Interstate. Interstate was a bit cheaper but Peak to Peak's rep spent way more time explaining the materials and ventilation options. The job was done on time and their crew was super tidy. I've had zero issues since. My neighbor used Interstate and said they were fine but communication was slower and they left some debris in the yard. I'd go Peak to Peak again.

But your cat's taste is probably terrible.

They're just a waste of time, lol.

My plant graveyard agrees with @jamesf26.

It's like we're all building our own little paper life rafts.
