Comp Door and Southworth Developments: A successful partnership in composite door excellence

Established in late 2021, Staffordshire composite door manufacturer Comp Door was founded by a team of composite door experts who wanted to transform the sector by providing a quality product with an attentive customer support function. After four months of refining their design, the team at Comp Door manufactured their first door in March 2022, and have since gone on to becoming industry leaders, producing 500 doors per week and building an impressive base of loyal customers. Loughborough-based Southworth Developments Ltd is one such customer.

Southworth Developments is a family-owned and operated company established over 30 years ago. A company that prioritises its strong reputation and customer care, Southworth Developments provides a dependable, no-pressure approach to their service. Their non-commission-based team aim to provide customers with the best service and products possible while not pushing unnecessary sales or services, and they take pride in being recognised as a reputable, trustworthy company among their customers. This customer-satisfaction business approach strongly resonated with Comp Door, who knew that they had a service offering that was different to those of their competitors.

In March 2023, Lee Marriott, Comp Door’s Business Development Manager, approached Southworth Developments to introduce them to Comp Door’s brand and service offering. Just from that one meeting, Southworth were instantly impressed and made the decision to embark on their partnership with Comp Door. In the 10 months since, they have sold and installed just over 75 Comp Doors, and they have many more in both the immediate and longer-term pipelines. In addition to this, they have 2 Comp Doors on display in their Loughborough premises.

Commenting on their partnership with Comp Door and how the service differed from their previous supplier, Southworth Development’s Business Operations Manager, Olivia Holliday explained, “As many companies will agree, happy fitters means a happy life. Before our partnership with Comp Door our fitters would often complain about the quality of the composite doors we used, and the time required to set them up. From the first Comp Door we installed our fitters have never once complained, the quality of the workmanship really is above the rest of the market. Issues experienced with our previous supplier have been acknowledged by Comp Door and understood, and their approach to a solution-focused design was a huge selling point. It seemed they had recruited the best talent in the composite door market to create a top brand and also employed the most up to date technology to help achieve their goals. From the initial meeting it was apparent they aligned with our goals of offering quality products with second-to-none service.”

The extent of Comp Door’s service offering was also discussed by Olivia, who said, “In addition, the marketing support from Comp Door is readily available to a great standard. Previously we struggled to even get a brochure from our supplier but since partnering with Comp Door we have been inundated with marketing resources, including regular brochure deliveries; plentiful stock of colour swatches; the sample boards for hardware that prove a great presentation tool; showroom doors; and a marketing team that keeps in touch and is there for any support required. Comp Door couldn’t make it any easier for us to sell their products. With Comp Door you are not just a number, you build strong relationships with all involved and they are always there to help and go above and beyond with whatever is required.”

The success of the partnership between the two companies is the result of a variety of factors, but their shared dedication to exceptional value and quality is arguably where their success thrives. Comp Door was founded on the belief that the composite door industry wasn’t fulfilling its potential. From poor quality products to unreliable customer service, the industry’s reputation was worsening and trust in the design was declining. With more than a century of combined industry expertise at management level, the Comp Door team worked to produce an innovative composite door design that was durable, secure, energy efficient, aesthetically pleasing, and was supported by an equally impressive customer care resource. Supplying their product to likeminded businesses that shared their ethos is incredibly important to Comp Door, and partnerships with companies such as Southworth Developments is part of what motivates Comp Door to continue innovating at such a high level.

Richard Diliberto, Sales Director for Comp Door, explains why an alignment of values creates a successful partnership with Southworth Developments. “There are decades of experience that form the foundations of Southworth Developments’ success that we at Comp Door really value. They are a reputable, trusted company that understands the unique needs and requirements of their customers because of their commitment to their local community, allowing them to provide a tailored and personalised service. They want the best for their customers, which is something that really resonates with us at Comp Door, and is the reason why we have established such a successful partnership. Listening to how Southworth were becoming increasingly frustrated with their previous supplier just reinforces our motivation to transform the composite door industry and improve its reputation through quality, reliability and innovation. It is customers like Southworth whose standards remain high that propel Comp Door and push us to becoming industry leaders.”
