My wife and I met with Dave Hawkins of Joyce Factory Direct to get a price on a patio enclosure. Dave was very professional and thoroughly explained Oasis sunrooms starting with manufacturing and continuing to the installation process. We feel that the Oasis brand of vinyl structure and the windows are of superior quality. We were impressed that Oasis manufactures their own building material. We have an existing enclosure that needs some repairs. We decide to go with a new enclosure from Oasis because of the quality and good looks.
