Mark Dicconson, managing director of John Fredericks Plastics, talks about why reliability and consistent quality, not price, defines value in today’s market, where reviews and challenging end users determine future recommendations.

In our industry, price has traditionally dominated the conversation. Fabricators are compared on cost per frame, and some businesses are prepared to cut margins to the bone to win work and lose money in the process.

But more than ever installers are discovering that chasing the lowest price can be a false economy. As I often say – the most expensive window is the one that doesn’t arrive in full, first time.

It usually gets a smile, but it captures a truth the industry still ignores too often. A window may appear cheaper on the quote, but if it arrives incomplete, incorrect, of a poor quality, or late, the real costs surface quickly and they land squarely on the installer, not the fabricator. It’s the installer who receives the negative reviews on social media.

Anyone who runs an installation business knows how precisely work must be scheduled. Fitting teams are booked in advance, homeowners organise their days around the appointment, and other trades may be timed to follow immediately after. When a job stalls because a size is wrong or a component is missing, everything stops.

The impact is immediate. A day of lost labour, hours spent chasing replacements, and difficult conversations with a homeowner who may have taken time off work. What looked like a cost saving becomes a financial hole – an empty diary slot, lost productivity, and the risk of reputational damage that lasts far longer than the delay itself.

Unreliability doesn’t just reduce margin, it can wipe it out. Installers aren’t just buying a window frame, they’re buying the ability to deliver a seamless installation and protect their own brand, reputation and profitability.

Customer service is sometimes treated as a soft touchpoint, but for installers it is one of the hardest financial levers. Being able to speak to someone who understands your requirements and the importance of quick responses, who can give clear answers, and who communicates honestly, can be the difference between a job completing smoothly and a job unravelling.

That’s why communication is something we place huge emphasis on at John Fredericks. Realistic lead times, accurate acknowledgements, and transparency when something changes, aren’t just good habits, they’re the cornerstones of reliability. Installers rely on a reliable supplier. They need to know where they stand so they can keep their own customers informed and their own team focused.

For us, fabricating windows and doors is only part of our role. Supporting installers so they can run profitable, well-organised and successful businesses is every bit as important. When communication breaks down, so does profitability.

Very few installers lose money because they paid slightly more for a well-made window. They lose money because they must return to a job due to poor quality or items are missing or damaged. That’s why quality and service have to be viewed not as an optional extra, but a necessity.

A product that is manufactured consistently, with accuracy and stable supply chains, minimises reworks and expensive service calls. Consistency matters as much as quality itself. Every installer has experienced the frustration of parts that fit perfectly one week and need adjusting the next.

That inconsistency is what eats into time, disrupts efficiency, and undermines the installer’s reputation. John Fredericks has traded continuously for 56 years and invests heavily in the latest technology to ensure consistent quality, service and performance.

Quality isn’t about adding cost. It’s about preventing cost.

As labour pressures continue and customer expectations rise, the industry is shifting. Installers are increasingly choosing suppliers who help them deliver a smooth, professional experience, not just those who are marginally cheaper. Reliability has become the competitive advantage that matters most.

This shift is changing how the best installers evaluate suppliers. The question is no longer simply, “Who offers the lowest price?” but rather, “Who helps me protect my margin and my reputation?” Fabricators who fail to appreciate this evolution risk being left to compete on price alone – the weakest position in any supply chain.

Price will always be a factor, but it should never be viewed in isolation. A window that arrives complete, correct, and on time is always the cheapest window in the long run.

Because ultimately – and I stand by this – the most expensive window is the one that doesn’t arrive in full.
