Liniar Technical Services Manager, Marc Wilcoxson

As an installer, how do you choose a supplier for your windows and doors with confidence they’re manufactured to the highest standards? If your priorities include reducing call-backs, giving customers reassurance, and securing repeat business and recommendations, choosing a supplier that’s regularly audited is an obvious step.

Liniar Technical Services Manager, Marc Wilcoxson, outlines the Liniar Approved Fabricator scheme and explains what it delivers for installers.

What is Liniar’s Approved Fabricator scheme?

Marc explains, “The scheme is designed to ensure that detailed fabrication instructions are followed precisely, using only Liniar-approved components. It allows fabricators to give installers - and ultimately homeowners - confidence that they’re buying fully approved Liniar products, manufactured to exacting standards and engineered to deliver optimum performance.

“Approved Fabricator status is reviewed at regular intervals by members of our Technical Team and includes comprehensive site audits. Ongoing training and technical support are also provided, ensuring our engineers remain confident in each manufacturer’s ability to fabricate products in line with Liniar’s required standards.”

Save time and money

“Liniar Approved Fabricators are subject to regular audits, with their production methods thoroughly assessed,” Marc continues. “This provides assurance that supplied products meet the highest quality benchmarks and enables installers to offer verifiable quality guarantees.

“In simple terms, selecting an approved supplier significantly reduces the risk of post-installation issues or manufacturing-related defects. That saves installers valuable time and money by minimising call-backs, while windows and doors are less likely to require remedial work. For homeowners, this also lowers the long-term cost of maintenance over the product’s lifetime.”

Reputation maintenance

“Consistency is critical when building and protecting your company’s reputation. Homeowners place their trust in installers to deliver high standards of workmanship, which is directly influenced by the quality of the products being fitted. Partnering with an audited fabricator helps ensure a consistent level of product quality, making it easier to achieve reliable, repeatable results.

“Strong reputations are built on word-of-mouth and online reviews. It’s well understood that meeting - and exceeding - customer expectations is one of the most effective ways to generate positive feedback. By choosing products from audited fabricators, installers can reinforce their reputation by consistently delivering high-quality products alongside professional installation. Happy customers are far more likely to recommend a trusted company to friends and family.”

Top-down peace of mind

“As part of the Liniar Approved audit process, every component used in the manufacture of Liniar products must be checked, verified, and approved by Liniar. This ensures each product performs exactly as it was designed to.

“It’s also important to recognise that product failure caused by poor manufacturing processes or sub-standard components can lead to property damage or personal injury. Sourcing Liniar products from an Approved Fabricator significantly reduces the risk of failure and the potential consequences that can follow.”

Marc concludes, “The Liniar range is designed as a complete suite of high-quality, fully colour-matched, fully tested, and guaranteed products. By buying from a Liniar Approved Fabricator, installers can be confident they’re receiving windows and doors that meet the exacting standards they were engineered to achieve.”
