Common Window Issues & When to Replace

Damaged or failing windows can lead to a range of problems, including:

  • Cracked or Shattered Glass – Weak or broken panes pose serious safety hazards and should be replaced immediately.
  • Failed Seals & Condensation – Misted or fogged-up double glazing means insulation failure, leading to higher energy bills.
  • Water Ingress & Drafts – Gaps, deteriorating seals, and broken frames cause leaks, damp, and heat loss.
  • Frame Damage & Rot – Wooden frames can suffer from moisture damage, warping, or rot, affecting stability and appearance.
  • Non-Compliant or Outdated Windows – Windows must meet BS 6262 glazing safety standards and modern energy efficiency ratings.

If repairs are no longer effective, a full window replacement may be the best solution for improving performance and compliance.

  • No Scaffolding Required – Using rope access techniques to minimize costs and disruption.

  • Certified & Experienced Glazing Technicians – Specialists in commercial, industrial, and residential window repairs.

  • BS 6262 & UK Building Regulation Compliance – Ensuring all glazing meets legal safety standards.
