Will new windows actually lower my energy bill?expand_more
They help, but the payback on going from decent double-pane to premium units is long. Replacing single-pane aluminum in a Salem ranch makes a real difference in both bills and comfort. If the goal is purely energy savings, attic insulation and air sealing usually return more per dollar.
How long does an installation take?expand_more
A crew typically does eight to twelve insert windows in a day. Full-frame work is slower — figure three to six per day with trim. The lead time to get the windows manufactured is the longer wait, commonly four to ten weeks after the measurement.
Can I replace just a few windows now and the rest later?expand_more
Yes, and it's common. Start with the worst — the ones that fog, stick, or sit on the weather side. Note the brand and line so later phases match, since profiles change over the years.
Are the warranties worth comparing?expand_more
Very much so. Look for how long the glass seal is covered, whether labour is included, and whether the warranty transfers if you sell. An installer's own workmanship warranty on the flashing and seal is separate from the manufacturer's and matters just as much here.
