Ask us for a quote today!

We offer a free, no-obligation quote service that includes a site visit to your home to measure your existing windows and doors. During this visit, one of our experienced Project Managers will guide you through the best options for your project - from aluminium or Klima (uPVC) frames, to glazing choices, hardware, and the most suitable configurations, whether that’s sliding windows, bi-folds, or something more customised.  

For new builds, we can provide a detailed quote directly from your plans – you can email them directly to us.

Community Involvement

At Design Windows Dunedin, we are proud to support local sporting clubs, community groups, and charitable organisations. As a local business, we believe strongly in giving back and helping the community that supports us.

Our team is involved with a range of initiatives and sponsorships across the region, including support for Taieri Golf Club, Otago Rugby, Mountain Biking Otago and Mosgiel Motorcycle Club.
