Step 4: Windows and doors: comfort, views, and noise control

Window and door upgrades can dramatically improve:

• natural light and airflow

• indoor comfort (less draft, better temperature control)

• noise reduction (important near I-5 or rail corridors for some homes)

• indoor–outdoor flow (bigger openings, better patio connection)

The best window/door plan accounts for:

• where light enters during the day

• privacy sightlines

• ventilation needs

• weatherproofing details and proper flashing
