If a&nbsp;surface\u2014such as the inside of a&nbsp;duct\u2014is contaminated, the disinfection will not achieve the desired effect, as bacteria or viruses can survive deeper within the debris. Therefore, performing disinfection without prior cleaning is only feasible in newly constructed buildings up to approximately 10 years old; otherwise, we strictly recommend cleaning before applying any disinfectant.<\/p>\n                    <\/div>\r\n                <\/div>\r\n                    <\/div>\r\n<\/section>\r\n\r\n\n\n\t\t<section class=\"services width margin--bottom-2x\" \n\t\t\t\tdata-has-illustration=\"1\" \n\t\t\t\tdata-per-line=\"4\"\n\t\t>\n\t\t\t<h2 class=\"section__title text-center\">Other Services<\/h2><img decoding=\"async\" src=\"https:\/\/alkion.eu\/wp-content\/themes\/unifer-alkion\/assets\/images\/services-polygon.svg\" alt=\"Polygon\" class=\"services-section-polygon\">\t\t\t<div class=\"services__wrapper-inner grid-x align-center\" data-equalizer>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/alkion.eu\/en\/service\/ductwork-sealing-in-new-builds-pre-inspections\/\" class=\"service-wrapper is-border fourperline\" data-equalizer-watch>\n\t\t\t\t\t\t<figure class=\"service-wrapper__thumbnail\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t<article class=\"service\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<h3 class=\"service__title no-decor\">Ductwork Sealing in New Builds &#038; Pre-Inspections<\/h3>\n\t\t\t\t\t\t\t<p class=\"service__excerpt\"><\/p>\n\t\t\t\t\t\t\t<div class=\"service__more-info\">More information <span class=\"service__arrow\"><\/span><\/div>\n\t\t\t\t\t\t<\/article>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/alkion.eu\/en\/service\/ductwork-sealing-in-buildings\/\" class=\"service-wrapper is-border fourperline\" data-equalizer-watch>\n\t\t\t\t\t\t<figure class=\"service-wrapper__thumbnail\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t<article class=\"service\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<h3 class=\"service__title no-decor\">Ductwork Sealing in Buildings<\/h3>\n\t\t\t\t\t\t\t<p class=\"service__excerpt\"><\/p>\n\t\t\t\t\t\t\t<div class=\"service__more-info\">More information <span class=\"service__arrow\"><\/span><\/div>\n\t\t\t\t\t\t<\/article>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/alkion.eu\/en\/service\/measuring-the-leakage\/\" class=\"service-wrapper is-border fourperline\" data-equalizer-watch>\n\t\t\t\t\t\t<figure class=\"service-wrapper__thumbnail\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t<article class=\"service\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<h3 class=\"service__title no-decor\">Measuring the leakage<\/h3>\n\t\t\t\t\t\t\t<p class=\"service__excerpt\"><\/p>\n\t\t\t\t\t\t\t<div class=\"service__more-info\">More information <span class=\"service__arrow\"><\/span><\/div>\n\t\t\t\t\t\t<\/article>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\n\n\n<div id=\"contact\" class=\"section-wrapper\">\r\n\t<img decoding=\"async\" src=\"https:\/\/alkion.eu\/wp-content\/themes\/unifer-alkion\/assets\/images\/polygon.svg\" alt=\"Polygon\" class=\"contact-form-polygon\">\r\n\t<section class=\"contact-form section padding grid-x\">\r\n\t\t<div class=\"small-12 text-center margin--bottom width width--general align-self-middle\">\r\n\t\t\t<div class=\"\">\r\n\t\t\t\t\t\t\t\t\t<div class=\"section__claim\">We are here for you<\/div>\r\n\t\t\t\t\t\t\t\t<h2 class=\"text-center\">Contact us<\/h2>\r\n\t\t\t\t<p class=\"section__paragraph width width--thin\">Do you have a&nbsp;question or need to seal your HVAC system?
