Getting anything at all done in the Seattle area is super expensive. Not sure why. The rep is wrong about the too cold bit though, even just what's in stock at Lowe's is rated to well below record lows for the region.
Price gouging. I've gotten quotes for fence replacements, heat pumps, roofs, window restoration. There is nothing that isn't ridiculous price in my experience. Every company has the same, supply/demand and reference to pandemic statements to substantiate their costs.
It's also the case that demand is huge.
