Andy (Home Aluminium Metal Works) quoted me $3.9K couple of months ago for installing double-glazed windows for my 3 bedrooms. I'm not sure if this quote was above market rate but the craftsmanship and the deliverables looked ok to me. However, recently he quoted me $950 to install double-glazed windows for my master bathroom. Should I proceed with this quote to install double-glazed windows for my master bathroom? What do you all think?
