I utilized Four Season's for a whole home window replacement. Sam completed an onsite review and took measurements and provided a quote a few days later. The windows were ordered and the installation took just 2 1/2 days to complete. From first contact to installation was much quicker then anticipated considering we arranged for financing thru the local utility company. I believe we were 100% installed within 30 days or so. Four Seasons is not a huge company so you get personalized service and you are not paying for an overpriced CEO. The bid and finished product were beyond our expectations.
