2. Jammed handle<\/strong><\/h3>\n\n\n\n

Often, a handle is jammed when the window is left slightly ajar and the locking mechanism attempts to engage\u2014this is the anti-slam device kicking in.<\/p>\n\n\n\n

\n
• The fix:<\/strong> The fitter will bypass the anti-slam mechanism to reset the handle. This is a common service that avoids unnecessary lock replacement.<\/li>\n<\/ul>\n\n\n\n

  Problem 3: Draughts and failed seals<\/strong><\/h2>\n\n\n\n

  If you feel a draught or see condensation forming between<\/em> the two panes of glass, you have a different issue.<\/p>\n\n\n\n

  1. Failed glazing unit seal (Between the glass)<\/strong><\/h3>\n\n\n\n

  Condensation between the panes means the hermetic seal around the double-glazed unit has failed, allowing moist air to enter.<\/p>\n\n\n\n

  \n
  • The fix:<\/strong> The entire glass unit (the IGU<\/strong> – Insulated Glass Unit) must be replaced. The frame itself is sound, and a fitter can simply replace the glass unit without removing the window frame.<\/li>\n<\/ul>\n\n\n\n

    2. Failed sash seal (Draughts)<\/strong><\/h3>\n\n\n\n

    If air is coming around the edge of the sash, the rubber gasket seals are likely perished, hardened, or compressed.<\/p>\n\n\n\n

    \n
    • The fix:<\/strong> A professional can remove and replace these seals with new rubber gaskets, immediately restoring the draught-proofing performance.<\/li>\n<\/ul>\n\n\n\n

      uPVC windows dominate the UK market due to their durability, low maintenance, and excellent thermal performance. However, after years of continuous use, even the highest quality uPVC windows can develop common problems. These issues often relate to mechanical failure, rather than the frame itself, meaning a uPVC repair specialist can often restore full function for …<\/p>\n","protected":false},"author":86,"featured_media":49066,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"pgc_sgb_lightbox_settings":"","footnotes":""},"categories":[3049,8,3226],"tags":[3116,687],"class_list":["post-49065","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-advice","category-how-to","category-windows","tag-advice-feature","tag-window-and-conservatory-specialist"],"acf":false,"featured_image_src":"https:\/\/www.ratedpeople.com\/blog\/assets\/2025\/11\/photo-1730718934352-504ab21fc22a-scaled.jpeg","author_info":{"display_name":"Hermione Wright","author_link":"https:\/\/www.ratedpeople.com\/blog\/author\/hermione-wrightaddmustard-com"},"yoast_head":"\n
