How to Customize Your Windows and Doors ?

1.Size & On-site Verification
When customizing your windows and doors, it's crucial to start with accurate measurements. We recommend providing us with the size and area picture of where the windows and doors will be installed. This information allows us to assess the space and recommend the most suitable design or series for your needs. Additionally, scheduling an on-site verification with our team ensures precise measurements and helps us identify any specific requirements or challenges unique to your space.
2.Material Selection
The next step is selecting the materials for your windows and doors. You have the option to choose the materials yourself or opt for our recommendations based on your preferences, budget, and desired functionality. Our experts can help you choose the best material and glass collocation to meet your aesthetic and practical requirements.
3.Quotation & Drawing
After finalizing the material and design details, we will provide you with a detailed quotation that includes the pricing for the customized windows and doors. Along with the quotation, you'll also receive drawings or mock-ups showcasing how the customized products will look in your space. These drawings help you visualize the final outcome and make any necessary adjustments before moving forward.
4.Confirmation & Production
Once you're satisfied with the quotation and drawings, and an order is confirmed, we proceed with the production process. Before production begins, we require the signed approval of the drawings from you to ensure accuracy and alignment with your expectations. Our production team then utilizes advanced techniques and quality control measures to manufacture your customized windows and doors to the highest standards.
5.Balence Payment & Delivery
Upon completion of production, we will inform you and request the balance payment as per the agreed terms. Once the payment is received, we coordinate the delivery or installation of your customized windows and doors. Our goal is to ensure a smooth and seamless process from customization to delivery, leaving you with beautifully crafted windows and doors that enhance the aesthetics and functionality of your space.
