PVC French Doors:
Custom or DIY Store?
Are you renovating and comparing prices for new PVC French doors?
When entering the world of windows, many face a dilemma: buy standard PVC doors at big box DIY stores, or choose custom PVC windows online?
The temptation to check prices for a standard 120x240 French door at a DIY store is understandable. They often show unbeatable list prices for ready-to-ship standard products. However, before buying, it is crucial to understand the technical and economic difference between an "off-the-shelf" standard window and a custom-made one.
In this guide, we analyze the facts objectively to help you make the best choice.
The Invisible Problem of Standard Sizes
The main difference lies in how your home is built. Window openings are never perfectly standardized.
1. "Custom" is the norm
For example, if your wall opening is 118x237 cm, a standard 120x240 cm door cannot be installed.
What happens? Expensive masonry work is needed to widen the hole, or the frame must be heavily modified, compromising the warranty and stability.
If the hole is larger, gaps are created. Using too much polyurethane foam to fill them results in poor insulation, drafts, and bad aesthetics.
2. Installation costs skyrocket
The apparent savings on the standard window are often completely wiped out by the extra installation costs.
A professional installer will take much more time to adapt a standard frame to an imprecise hole compared to the fast installation of a custom-fit window.
