Very prompt call back and immediately set an appointment. Sales guy was great.
Delivery of windows was quick. Downside was that I had a flight the evening of the installation date. I stressed several times that I had a cutoff time. Installer was 2.5 hours late and did not finish on time so I missed my flight. The woman who scheduled the install reassured me that they could finish the job on time but with hindsight I should have trusted my instincts to push the install out to the following week - she had never seen the job and had no idea of what kind of work was involved.
However this aside, I'm happy with the quality of the work.
