uPVC is ultraviolet-stabilised PVC. It’s a rigid, durable material specifically engineered for windows and doors. Unlike PVC, uPVC has no softening chemicals, making it stable and long-lasting. Installed worldwide for 50+ years, it’s strong, weather-resistant, thermally efficient, and maintenance-free.

Homerit supplied uPVC windows last 40+ years in Wellington’s UV-heavy climate, far longer than aluminium (20–30 years) or timber (25–35 years with maintenance). Many homes installed in 2005 still look and perform like new.

Minimal – just occasional cleaning with warm soapy water and annual lubrication of hardware. No painting, sanding, rust removal, or rot treatment needed.

Yes – uPVC frames are about 1,000x less thermally conductive than aluminium. This means warmer homes, lower heating costs, and virtually zero condensation on frames.

Not at all. Premium VEKA profiles with a small selection of finishes look high-quality.

Absolutely. Blue Door specialises in heritage-sensitive installations, with a small range of finishes, correct proportions, and council-approved designs.

$1,000–1,600/m² installed, depending on window type, size, glass, and finish. Pricing includes premium VEKA profiles, Siegenia hardware, double glazing, LBP-certified installation, building consent handling, and a 15-year warranty.

Quality-matched uPVC is comparable or even cheaper than aluminium. Plus, superior performance means lower heating bills and minimal maintenance.

Typically 6–9 years in Wellington homes replacing single-glazed or basic aluminium windows. After payback, savings continue for decades, plus no condensation damage and reduced maintenance costs.

Yes – energy-efficient, condensation-free, low-maintenance windows increase buyer appeal, improve Homestar/EER ratings, and adds to the overall property value in Wellington.

30–40% reduction for typical Wellington homes, depending on what’s being replaced and home size.

uPVC 100% eliminates condensation for frames. Glass condensation depends on glazing type; Low-E significantly reduces condensation.

Perfectly. uPVC is immune to salt corrosion, unlike aluminium or timber.
