Outside glass takes everything the weather throws at it. Sprinkler overspray, dust off the road, pollen, and hard water spots. We hand wash the exterior glass, clean the screens and tracks, wipe the frames and sills, and leave the view clear from the street.
The tech who quotes it is the tech who cleans it. One point of contact from the first walkthrough to the last pane.
A specific number for your glass, in writing, that does not move once we are on site.
If a pane still hazes after we leave, we come back and finish it. 4.8 stars on Google says the work holds up.
Tell us which windows, the address, and how long the spotting has been there. We will scope it and put a fixed number in writing, for free.
