The best way to do it is really get a number of windows and rough sizes of the windows and then you can email them that and they can give you a price estimate.
I never met with a single person in-person until they came out to do actual window measurements.
I just did it through email and phone.
We went with the blind spot. They weren’t the cheapest or the most expensive. But they had lots of great options, great warranty (lifetime) and they gave us really great customer service.
If you have any questions you can boardmail me and happy to talk more details.
