My appt was for 10am-2pm, I received a call shortly after 10am that the installers were on their way. I met them outside my home and helped them prep my vehicle for a new windshield. When I made the appt they said it could take up to 90 minutes but my installers were finished in about 30 minutes. No mess, no fuss, very easy to deal with and I got a great price from them that includes lifetime chip repair. Very happy and will recommend them to others!
