I used iWindowsCBD for (really high) cathedral ceiling high dusting and high vacuuming and I'm blown away with the results. Tim did an incredible job with the high dusting and high vacuuming, the ceilings might be 30+ years old but they look brand new! Tim was very knowledgeable, helpful and accommodating of all my requests and questions! I could not recommend iWindowsCBD more highly for the quality of their work and their service. Thank you so much Tim!
