Simple approach

Meet You Where You Are

As our client, We believe in meeting you where you are in the process of designing your dream. All our clients begin at the beginning; and we are here to help.

We work with Architects, Design-Build companies, Builders and homeowners that want to enjoy an energy efficient home. We provide premium products from our network of partners both nationally and internationally.

The Loewen Window Center does not offer complete design services to homeowners. We have a refined list of preferred Architects and Designers that we can share with you and you may choose the right partner to sharpen the vision of your dream.

We pride ourselves on our relationships with our vendors, partners and clients. Installed services are available through our contractors directly to homeowners. We do offer subcontracted warrantied installation to our contractor partners.
