UPDATED Nov 2019. Simon addressed our concerns, after this review was made. He personally came to our home and re-sealed all our windows that were treated. He recommended we keep humidity at 0% in home. One window did improve after he sealed it. The other ones did not. He has not recommended a new window pane (removed, new window pane, and resealed). He is nice, and I do think he is trying to rectify our situation.
We had 5 windows treated with defogging in April 2019. I suspected at the time, that it was not done properly. The technician procedure did not match what was done on the promotional video. Afterwards, I did explain this to Simon (owner); how the procedure was not the same as the video. He assured me it would take 4-6 weeks to have resolution. In July, still no resolution. He sent same technician out a few weeks ago, to caulk the window. The technician did not address all windows that were initially treated. Attached photos are July 2019 and Sept 2019. We've been in communication with Simon to come up with a resolution. Currently, he suggests we pay more to have him replace the glass. I regret paying so much at the time, and requested re-imbursement so I could deal with another company (we would replace windows at this point!). We really believed all the other reviews here, and on google. I'm very disappointed that I wasted money on this. I will update photos and review if the fogging ever gets better. We've been waiting 5 months.
