We spent a total of $42,000 on Miracle Windows across three years in the process of replacing all our windows one side of the house at a time.
I have had two significant issues with them, one of which is still not resolved and will likely never be resolved.
1) Invasive company with promise they don't honor.
2) Not honoring their warranty, which takes away the value of paying such high prices.
They were so invasive, that even after telling them "no" to buying the two tiny and fixed pane windows we have left because they wanted ridiculous money, that I even caught the (who is one of the owners) trying to meet my disabled wife without me present to try to close the sale with them. It came to the point I had to ask him forcefully to leave the house and forbid him to come back. he was tricking her into receiving him by promising prices that would double by the time he arrives.
One of the work they did is a $5,000 French-door leading to our courtyard. The primary door opens fine, but the second door has had to have three service visits to try to fix it. Every time the service guys shows up with incomplete parts. To this day this door is not to spec and I will likely have to hire an independent contractor to have it definitely fixed.
Claimed loss: A $5,000 non-fully-functioning door.
Desired outcome: Definitive repair.
