After-sales service guarantee
At our factory, we are committed to providing reliable double-wing expansion houses and professional after-sales support, ensuring your peace of mind throughout the use process. We take full responsibility for the quality of our products and provide a comprehensive after-sales guarantee as follows:
Quality Guarantee Period
We provide a 3-year quality guarantee for all our double-wing expansion houses from the date of delivery. During the guarantee period, any damage or loss caused by non-human factors (excluding damage caused by improper use, man-made damage, natural disasters, and other force majeure factors) will be fully borne by our factory.
After-Sales Maintenance Support
If any non-human damage occurs during the guarantee period, we offer flexible and convenient maintenance solutions to minimize your trouble:
Cost Bearing
All expenses incurred for on-site maintenance, including local material purchase and labor hiring, will be fully covered by our factory. You only need to provide the corresponding purchase invoices and labor receipts, and we will settle the payment promptly.
Accessory Supply
If the damage can be repaired by replacing accessories, we will send the required original accessories to you by express delivery free of charge, ensuring timely maintenance.
Flexible Delivery Option
If you are not in a hurry to repair, the required accessories can be delivered together with your next order, saving you additional logistics costs and ensuring the consistency of product parts.
Our Commitment
Customer satisfaction is our top priority. After receiving your after-sales request, our professional team will respond promptly, confirm the problem details with you, and provide a reasonable solution within 24 hours. We adhere to the principle of "quality first, service first" and strive to solve all your after-sales worries, allowing you to use our double-wing expansion houses with confidence.
