Brian is building a new house in New Jersey and has selected Andersen 400 Series windows. So far, so good. The problem is how the windows have been installed by Brian’s builder.
Many of the manufacturer’s installing instructions have been ignored, Brian writes in a Q&A post. The contractor used no caulk, chose Tyvek housewrap tape instead of flashing tape, and failed to overlap the Tyvek by at least 6 inches, as required by the instructions.
“It looks like they lined the rough openings with Tyvek and a bit of Vycor Plus flashing at the botton only, then installed the windows without caulk, then installed a layer of Tyvek across the tops of the windows, and over the top nailing flange, then taped the flanges with Tyvek housewrap tape,” he says.
In an earlier post on the same topic, Brian outlined what he believed were the shortcomings in the builder’s installation methods. When he asked around for advice, the replies were not encouraging: One certified Andersen installer told him he was convinced the windows will leak.
“My builder says the windows are fine,” he wrote. “They have installed thousands of them like this, he says, and never had a problem. He very much wants me to drop the subject.”
What’s the best course for Brian to take now? Should he insist that the windows be redone? “I am prepared to redo,” he says, “but given the cost I would like to be certain that it’s really necessary.”
Brian’s painful predicament is where this Q&A Spotlight begins.
It shouldn’t cost you a dime
The building code requires that all materials be installed according to the manufacturer’s instructions, GBA editor Martin Holladay says, so the cost to Brian should be zero.
