This review is based solely off of my experience calling for a quote, as I did not decide to use Marc's Glass based off of my interaction. So I can't vouch for their actual quality of work and end result including billing.
I called for a quote to replace some window glass for my home, I was quoted $490, and $290 per window, including installation. I thought it was sort of strange Marc didn't ask any details other than measurements, but as I am not a window guru and this was the first place I called I wasn't sure if anything else mattered or affected the price.
I proceeded to call a few other companies, just to compare pricing. I was quoted MUCH less by another reputable company - $430 to replace the glass in BOTH windows. This company also asked several questions about the type of window, etc.
I sort of wondered if Marc was trying to rip me off, so I had my husband call back and ask for a quote. He quoted him $100 less. Maybe it's cause I'm a chick.
So just beware of strange/shady pricing - call around for comparable pricing.
