Earlier this week, I shared the installation of our new window in the living room in real time - The question we keep getting is "How much did it cost?" The window–a good quality, 5’x6′, custom Pella window we special ordered from Lowes–was $335. A steal, right?! I hate commenting prices on contractor wages, because they vary so much from place to place. But I’ll say we paid him about what we paid for the window to give you an idea.
