Part 3A: WINDOWS: WHY THEY’RE CRITICAL
Our series of "Rebuilding Stronger Smarter" focuses on the "smarter" aspects of architecture and construction.
Kicking off with windows, Series 3A discusses why windows are critical to the life of your building, and how you can tell if your windows are in good shape, or need to be repaired or replaced.

Repair? Replace? Leave As Is?
A simple way to tell whether your window needs replacement or repairs is to look around the edges.
If the caulking around the edge of the window is missing or damaged, repair it!
And if there is any damage to the window frame, glass, or rusting or other damage to the sill, replace it!
WATER & AIR
Windows can typically fail your home in two ways:
Moisture damage, where water or moisture has made its way through the window opening to the inside of your house
Air intrusion, where the window hasn't been properly sealed, and outside air is able to mix with your inside conditioned air.
Both scenarios can lead to mold and other hazards.
FAILING INSTALLATION
This picture shows an example of a failed window installation.
It may have been adequate when it was completed 60 years ago, but today, you can see chipped paint and rust marks, indicating air and moisture damage to the inside of the frame over time.
Windows that look like this should absolutely be replaced.
PRETTY GOOD INSTALLATION
Now this window was installed fairly recently, and you can tell because the sealant is visible and clean; it hasn't been worn away.
The vinyl frame doesn't have any obvious signs of damage, and the sill is a non-porous material that hasn't eroded.
This window can likely stay as is, with minor repairs.
SMARTER INSTALLATION
The workmanship in this installation photo is superb!
The caulk sealant around the interior side of the window is barely visible; it's been protected from scraping or other damage to ensure a longer-lasting seal.
The window frame is extruded aluminum, which has fewer assembled pieces than vinyl, which mitigates moisture damage to the inside of the window frame.
This is the better way to have your windows installed!
WHAT SHOULD WE DO?
When dealing with your existing windows, remember to:
INSPECT the window frame for damage, missing caulk, and spalling or bubbled window sills.
REPAIR caulk and exposed damage to surfaces.
REPLACE broken or worn out windows. Aluminum impact-rated windows are best, but vinyl replacement windows will also work!
