{"ai_json_enabled":true,"answer":"Some underlay manufacturers describe selected products as being guaranteed for the life of the carpet installed over them. Airstep uses this wording in its product material, but it should be read as a product-specific warranty rather than a promise that every underlay problem will be covered in every situation. Warranty conditions can depend on correct installation, compatible carpet, normal use and other exclusions. Before buying, ask for the current written warranty for the exact underlay so you can see what 'life of the carpet' covers and what evidence may be needed if a claim is ever made.","answer_source":"prospect_knowledge_airstep_dunlop","category":"Underlay, Comfort & Sound Reduction","category_slug":"underlay-comfort-sound-reduction","created_at":"2026-09-07T02:43:58+00:00","date_published":"2026-09-07","display_date":"2026-09-07","id":"drip-20260907-1629fb37","image_ids":["bcc-gen-013","bcc-real-004","bcc-real-009"],"image_url":"","last_updated":"2026-09-07T02:43:58+00:00","local_cache_status":"manual_knowledge_expansion","publish_status":"published","published":true,"published_at":"2026-09-07T02:43:58+00:00","question":"What does a 'lifetime of the carpet' underlay guarantee actually mean?","question_intent":"underlay_product_and_buying_guidance","rss_enabled":true,"rss_pub_date":"Mon, 07 Sep 2026 02:43:58 GMT","scheduled_for":"2026-09-07T02:43:58+00:00","schema_enabled":true,"site_key":"british-carpet-company","slug":"what-does-a-lifetime-of-the-carpet-underlay-guarantee-actually-mean","source":"manual_underlay_knowledge_expansion","source_record_ids":[],"source_type":"manual_underlay_knowledge_expansion","source_urls":[],"status":"active","tags":["underlay","Airstep","warranty","lifetime guarantee","carpet life"],"updated_at":"2026-09-07T02:43:58+00:00"}
