Choosing the Right Entry Door

Your front door is the focal point of your home's exterior. For Toronto's climate, consider:

Steel Doors: Most affordable and secure option. Good energy efficiency with foam core insulation. Can dent and may rust at the bottom if not maintained. Best for: budget-conscious homeowners and rental properties. Fibreglass Doors: Best overall choice for Toronto homes. Excellent insulation, weather resistance, and durability. Can mimic wood grain appearance. Will not rot, warp, or rust. Best for: most GTA homeowners. Wood Doors: Beautiful, classic appearance with natural warmth. Requires regular maintenance (painting, staining, sealing) to withstand Toronto weather. Can warp and swell with moisture. Best for: heritage homes and design-focused homeowners.

Energy Efficiency Considerations

In Toronto, where heating and cooling costs are significant, your doors play an important role in energy efficiency:

• Look for ENERGY STAR certification for exterior doors
• Weather stripping should be intact and compressible along all edges
• Door sweeps prevent drafts at the bottom
• Multi-point locking systems pull the door tight against the frame
• Insulated cores in steel and fibreglass doors provide R-values of R-5 to R-15

A poorly insulated door can account for up to 25% of a home's heat loss through the building envelope.

Signs You Need a New Door

Consider replacement if you notice:

• Drafts around the door frame, even when closed
• Difficulty opening or closing due to warping or settling
• Visible damage including cracks, rot, peeling, or rust
• Condensation between glass panes in doors with windows
• Increased energy bills that may be partly due to poor door insulation
• Security concerns with old or damaged locks and frames
• Outdated appearance affecting curb appeal and home value
