Sunny,

Thank you for your question and interest in LaCantina Doors.

Generally speaking, pricing is largely based on a per panel basis. It is most cost effective to reduce the number of panels per opening. For example, based on a maximum panel width of 39", a 9 ft wide opening would be most cost effective using a 3 panel configuration.

The suggested retail pricing is roughly $667 per ft. Based on 9' wide opening, the cost would be about $6,000 or $2000 per panel depending upon the size and glazing options.

Please note each folding door systems is made to measure. And as we sell through dealers, pricing will vary.

Most dealers also offer installation and pricing will also vary. Based on feedback from the field , experienced installers average roughly $75 per linear foot for installation. Hope that helps.

If you have any further questions, please do not hesitate to call 888-221-0141.
