FAQs
How do I know which window material is best?
The best material depends on your climate and maintenance preferences. uPVC is low-maintenance, aluminum is durable for coastal areas, and wood offers traditional aesthetics with higher maintenance needs.
Is professional installation really necessary?
Yes. Even premium, high-efficiency windows will perform poorly if the sealing, gap filling, and alignment are not handled by experienced professionals.
What should I look for in a window warranty?
Look for comprehensive coverage that includes the glass, frame, hardware, and the installation labor itself. A longer warranty usually reflects the manufacturer’s confidence in their product.
