Thank you for cleaning my roof space. Before I had the clean I have had 2 sinus operations, countless specialists and GP visits, many days off work and school, ridiculous amounts of antibiotics and daily antihistamines and cortisone. In the 5 months following the clean I have had 7 antihistamines. 4 sinumax tablets, 6 puffs of cortisone, no antibiotics, specialists or GP visits. It turns out I am highly allergic to house dust mites and your roof clean took them away. I can't wait for my next annual clean. Thank you SO much for giving me fresh air to breathe.
