See What our Satisfied Clients are Saying About Us on HomeStars

Over the past two years, we had all of the windows and doors replaced on our 24+ year old home. Prior to that (about 15 years ago), we had them replace windows in our previous home, including installing a bow window. Verdun has done a tremendous job, from measurement, installation, and after-care. We would not hesitate to recommend them to anyone and in fact have recommended them to family members who have gone on to use them. Wonderful company.
