Frequently Asked 'Door' Questions
For Illinois’ freeze-thaw cycles and humidity, fiberglass and steel exterior doors typically perform best. Fiberglass resists warping, rotting, and denting while offering good insulation, and steel provides excellent security and durability with proper rust-resistant finishes. Wood doors can be beautiful but need more maintenance and protection from moisture. Look for doors with insulated cores and quality weatherstripping to handle seasonal changes.
When choosing a door material in Pontiac, consider insulation value, maintenance needs, and how exposed the doorway is to sun, wind, and moisture. Fiberglass is a strong all-around choice for energy efficiency and low upkeep, while steel is ideal if security is your top priority. If you prefer the look of wood, consider engineered wood or a fiberglass door with a wood-grain finish for better durability. Also check local climate patterns and energy costs to decide how important a higher R-value is for your entry.
Accurate measurements of the rough opening, jamb depth, and swing direction are critical before ordering or installing an exterior door. Make sure the subfloor and threshold area are level and solid, and always use shims to keep the frame plumb and square. Use high-quality exterior-grade caulk and proper flashing to seal against water intrusion. Finally, adjust hinges and weatherstripping after installation to ensure a tight, draft-free fit.
Fiberglass doors generally offer the best combination of energy efficiency and low maintenance, especially when they have insulated cores and quality seals. Steel doors can be very energy efficient as well, but they may need occasional touch-up paint to prevent rust if scratched. Wood doors provide a classic look but typically require regular sealing or painting to protect against moisture and temperature changes. When comparing products, look at the door’s energy performance ratings (like U-factor) and the warranty terms for finish and structure.
