Bi Fold Doors: Factors Impacting Final Cost

Before purchasing a bi fold door, it’s important to assess your budget. This requires looking at the initial cost and the final price including all of the options you want. The based prices are one thing. Most customers add to that by ordering at least an upgrade or two, sometimes more. After all, the idea is to get the most comfort and longevity out of it.

  1. First, determine the type of material. Aluminium, plastic, and timber can each be great options but come at different costs which can vary depending on the installation.
  2. Quality is a factor too, as the cost of low end vs. high end systems can vary dramatically even given a chosen material.
  3. Many door companies will charge for a survey. Check with the supplier beforehand to determine this cost. Installation can add significant charges to the final bill as well.


In addition, popular options and upgrades add to the listed prices seen on product webpages. It is important to not get fooled by these. The final price ultimately depends on what you have included. Some of the more significant upgrades include integral blinds. These can add a couple of hundred pounds to the price, and the cost is usually listed per panel.

Other pricey options may include trickle vents, a projection cill for directing away rain water, and triple glazing depending on whether it is compatible with the bi fold door. Level thresholds, external locking handles, and alternate colours not in stock can come with a surcharge.

The goal is to find a bi fold door that matches the specific needs of the customer. Of course, this can mean a higher price than expected. The final cost can be estimated by discussing your needs with the supplier before the project starts.
