I booked an appointment and gave them my credit card information. I got no notification of when they were coming - they just showed up randomly one day and repaired the gutters (and left the broken gutters behind for me to clean up).
But for some reason they never charged my card. A month after the service they called requesting payment by check or email. That week my son was born and I totally forgot to send payment. Rather than a final reminder - I got a nasty letter from a collection agency demanding payment. I paid right away of course, but I can't figure out why they wouldn't have just called me before sending a collection agency after me. Instead they went straight to threatening my credit.
Also wish they'd told me I'd have to dispose of the busted gutters on my own in a hatchback.
Strongly recommend you look elsewhere. There are many companies doing this kind of work that are run much better.
