Next, appropriate remediation must be carried out: specialized cleaning, removal of contaminated materials, and implementing steps to fix dry rot (Serpula lacrymans)  wood and prevent it from returning. Our report always includes specific recommendations on the actions to take and can serve as a reference for insurers, contractors, or health authorities. The faster dry rot (Serpula lacrymans)  is treated, the less risk it poses to the occupants&#8217; health and the building&#8217;s value.                                <\/div>\n
