Reviews
“
After getting the quotation for 4 pairs of folding doors, we still chose WANJIA™. The price, workmanship and service all meet my requirements. Will come back to them when I'm ready to replace other windows and doors.

WANJIA™ is a very trustworthy door and window manufacturer. From quotation to production packaging, to installation instructions and more. I customized sliding windows and folding doors, and there are shutters between the glass and the glass. My wife and I are very satisfied, and I am very happy to cooperate with WANJIA™!

I highly recommend Wanjia windows. We used them for our house in Canada and they were excellent. We are now working with them to replace the windows in our house in the Philippines. Excellent customer service and sales staff. The quality of the product is top notch.

FAQs
For optimum efficiency, we need to quote you faster and more accurately based on the information below.
1. Provide window and door size, quantity and related drawings
2. Profile (aluminum or upvc/vinyl) and frame color
3. Glass type, thickness (single/double interlayer or others) and color (tinted/reflective/Low-E or others, with or without hydrogen)
We mainly use two packaging ways to avoid scratches or collisions on the product surface.
1. Bubble bag + EPE + wooden crate
2. Air bubble film + wooden frame
Usually we will ship within 25 days after the deposit and drawings are confirmed. But it must be decided on a project-by-project basis, and if the project is too large, it may take longer. We will strictly guarantee the quality of your doors and windows and the shortest delivery time.
About shipping: you need to tell us your delivery address, we will calculate the specific price for you.
You can use Credit/Debit Card, PayPal or T/T.
