We have had hundreds of windows replaced at our facility over a period of 5 years. CWI has replaced all of our older wooden/aluminum windows with new Winstrom aluminum windows. This has not only helped our elderly population with ease of opening and cleaning these windows, but it has had huge benefits with regards to maintenance and energy savings. Kevin Sweeney has been great to work with, and has always delivered the product on time and within the specified budget. We have found the CWI crews to be professional and courteous in very sensitive areas of our hospital and areas of the convent. We have had an excellent relationship with Kevin and Commercial window installers over the years and would recommend them to anyone in need of a large commercial or residential window replacement project.
