I’ve got a project house that was a victim of a previous, fast money flipper. It’s an older house that had the original wood sashes removed and replaced with cheap-o vinyl windows. The work is sketchy, so the windows don’t operate as they should. They look trashy regardless. I’m looking to replace them, and this is uncharted territory for me. The windows at the “big box” stores are economical, but similar. “Nice” windows, like from Marvin, are pricey, and could dig deep into my profit margin. I’ll be installing them myself, and am looking for a practical middle ground. So, where does everybody get their windows?
