Four of my windows had condensation and when I called in a window company, they told me to change all the windows on the south side of my house. Firstly, they told me they couldn't just replace the glass units, and also in order for the windows to match, they had to replace even the windows without condensation. You can be sure I will never use that window company!
I didn't think that was necessary and so I called Pilkey Glass and found out that for condensation, I only needed to replace the double glaze sealed glass units without having to replace the whole window.
I had one big window and 3 small ones replaced by Pilkey Glass for the total cost of $723 (materials, labour and taxes all included).
The window sealed units in my subdivision were very difficult to remove but they did a great job. There was a slight blemish on one of the glass units but considering the difficulty of the job, I wouldn't complain at all. They also did a great job cleaning up all the glass.
They did such a good job that I will most probably use them again for the shower glass enclosures for my tub to shower conversion later.
I would definitely recommend Pilkey Glass !
