Andersen Windows in a Stone Home in Malvern, PA

Installing windows in a stone home is a different job than a wood-framed exterior. On this Malvern project we set Andersen double-hung and casement units into thick fieldstone walls, where the openings are fixed and the reveal has to be right on every side. The result is crisp new windows with clean interior trim, set into stone with no gaps and no shortcuts.

What the Malvern window project involved

Stone openings do not forgive poor measurements, so the fit and the flashing have to be exact. The scope covered:

  • Careful measurement and fitting into fixed stone openings
  • Andersen double-hung and casement units set plumb and square
  • Flashing and sealing integrated with the wall
  • Clean interior trim and deep sills against the stone
  • Consistent reveals so each window reads correctly

Why installation makes the window

Even the best window underperforms if it is installed poorly. Proper flashing, sealing, and insulation around the unit are what make the rated performance real, and on a stone home the fit and reveal are what make it look right. Choosing an efficient unit matters too, and you can check what efficiency ratings mean through ENERGY STAR.
