Note the fine print of the contract. Assemble window without covering furniture and / or warning. Leaves new frames with black stripes. Nicely remedied. For 2nd guarantee item, large crack at the top of the window frame, according to the mechanic who immediately disappeared into the toilet upon entry, the kit edge was repaired. "We come to a customer for warranty 10 times a year." Disagreement about whether or not enough spirit level mounted basement window was dismissed by shouting, sarcastic remarks, an appeal to his authority as a mechanic. I'm done with Designbouw.
