How does invoicing/payment work for most Window Replacement & Installation Company projects in Longmont?

Every project differs, but you should ask any window replacement & installation company for an estimate, before they do any work. In fact, ask for their general payment terms before any window services work is done.

Window well has rust and needs repair. A couple spots have rusted through so might need some filler. Nothing horrible, but trying to be proactive before it gets worse. Clean, rebuild, passivate, protect the galvanized steel. Would be preferable if you have pervious experience with such repairs.
