A Homeowner's Guide to Replacing Windows
Drafts, foggy glass and sticky frames are all signs. Here is how to decide on replacement and choose windows that fit your home.
Signs it may be time
Not every tired window needs replacing. Worn weatherstripping and broken hardware can often be repaired. Replacement is worth considering when you notice:
- Fog or condensation trapped between the panes of glass
- Frames that are rotting, warped, cracked or corroded
- Drafts that remain after new weatherstripping
- Windows that stick, will not stay open, or cannot be locked
- Outside noise that disturbs sleep or work
Choosing a frame material
- Vinyl: low maintenance and widely available, with good insulating value.
- Fiberglass: strong and stable through temperature swings, and can be painted.
- Aluminum: slim frames and large glass areas; look for thermally broken frames and finishes rated for coastal exposure.
- Wood and clad wood: classic appearance, with exterior cladding to reduce upkeep.
Near the ocean, ask specifically about corrosion-resistant hardware and finishes, since salt air is hard on metal parts.
Glass that does more
- Dual-pane glass is the common standard for improving comfort over single-pane windows.
- Low-E coatings reflect heat and reduce fading of floors and furniture.
- Laminated glass adds security and helps reduce outside noise.
- Tempered safety glass is required in certain locations, such as near doors, tubs and showers.
Opening styles and safe exits
Casement, sliding, single-hung and awning windows each suit different rooms. Bedrooms need at least one window large enough and easy enough to open for emergency escape, and security locks should release quickly from inside.
Do not forget fresh air
New windows seal far better than old ones. That is great for comfort, but it also reduces accidental ventilation. Plan for fresh air with operable windows in the right places and exhaust fans in kitchens and bathrooms to keep moisture and mold in check.
Planning the project
Windows are usually replaced one opening at a time, so the home stays secure and weathertight. Custom sizes take time to manufacture, so plan ahead. Replacement windows may need a permit and must meet California energy standards.
