When you walk into a door showroom or glazing showroom, you should feel confident, informed, and supported – not rushed, misled, or unsure.

Unfortunately, not every supplier puts your home’s needs first. At Prolux, we believe in giving customers the tools to spot red flags, so you can make confident decisions and avoid buying products that don’t meet your expectations.

Here are some key signs that a showroom may not be up to standard – and what you should look for instead.


1. High-Pressure Sales Tactics

A quality showroom experience should be calm, helpful, and informative. If you’re being pressured to buy on the spot – especially with claims like “limited stock” or “prices going up tomorrow” – take a step back.

Things to watch for:

If you’re visiting a showroom to explore uPVC door supplier options, for instance, you have every right to ask which manufacturer they use and whether you can view product specifications beforehand.


2. Dirty, Damaged or Poorly Maintained Displays

A professional glazing showroom should be clean, well-lit, and take pride in its displays. If you notice streaks, scratches, or fingerprints on the demo windows or doors, it could indicate poor quality control – or a lack of care in presenting products.

Why this matters:

Always feel free to ask staff whether a mark is superficial or a sign of damage. A good supplier will welcome your questions and explain how they maintain their displays.


3. Missing or Vague Warranty Information

One of the most overlooked areas in a showroom is after-sales protection. A reputable supplier should clearly explain what happens after you buy – particularly when it comes to product guarantees and workmanship warranties.

Ask for:

At Prolux, for example, we offer a 10-year insurance-backed guarantee – so our customers know they’re protected long after installation.


4. Lack of Personalisation or Product Knowledge

Every home is different. If a showroom representative isn’t asking you about your home layout, energy needs, or design preferences, it could be a sign that they’re more focused on the sale than your solution.

A good door showroom will:

If it feels like a one-size-fits-all experience, trust your instincts and seek out a more attentive team.
