    Eric and his crew did an excellent job, They worked cleanly and professionally. I hate to hire a company and when the work is done, feel I could do it better myself. The job was meticulous from measurement to installation. My Thanks to all involved.

    I have been on a 5 Year plan to replace all my windows in my 100 year old house. All windows are now done - and I will look at new sliders next year! Every time - I went thru the process it was flawless. From sales to installation - professional prompt world class service. Never an issue - really never! Are these windows more expensive than others - I am sure they are - but honestly - they are superior quality and worth every penny - and my philosophy is if I were to have done this project with lower quality (less expensive) windows - I'd be doing it again 10 years from now. I KNOW these will last !!!
