With nearly half of UK adults using less home heating fuel due to rising costs, having energy efficient windows and doors is more important than ever this winter. Defective or drafty windows and doors can lead to significant heat loss, forcing residents to turn up the thermostat and incur higher energy bills. Replacing damaged windows and doors with high performance options can improve a home's energy efficiency and allow residents to maintain a comfortable temperature affordably.

Signs that windows or doors need replacement before winter include:

• Drafts - Cold air coming in around windows or doors signals the seal is broken or damaged. Drafts can raise heating bills by up to 25%.

• Condensation - Fog or water buildup on windows indicates poor insulation and air leakage. This moisture can cause mold growth.

• Rotting wood - Cracked, warped, or rotted window frames and door jambs mean the window seal is compromised.

• High energy bills - Unusually high heating costs often point to an insulation issue with windows or doors. An energy audit can identify problem areas.

Experts recommend having any defective or inefficient windows and doors replaced by late summer or early fall, before cold weather sets in. This allows time for adjustments and ensures upgrades are in place before winter. Investing in properly installed, energy efficient replacement windows and doors now can save money on heating bills for years to come by keeping cold air out and warmth in this winter and beyond.
