The Prep Work That Makes Installation Go Smoothly

For simple like-for-like swaps, many homeowners are only dealing with routine replacement work, but enlarging a window opening or altering the structure is a different matter.

Old wood rot, water damage, and loose framing often show up only after the surrounding material is opened up.

Once the opening is exposed, the installer inspects the sill, jambs, and surrounding framing for rot, soft spots, or signs of past leaks. If the installer finds hidden damage, it needs to be corrected before the new unit goes in. A smart installer uses this stage to reduce future leak risk, not just to hide the old problem.

Then the crew seals and insulates the spaces around the window, taking care not to overpack the opening.
