Service with Style

Another successful full house renovation project

Published 22nd October 2023 by Keren Keyworth Categories: Updates

Starglaze – Sternfenster’s installation division – recently completed an impressive installation at the newly purchased home of Mr and Mrs Prestwood, near Lincoln.

Purchased in January 2023, the couple knew that they had urgent renovations to embark upon; first and foremost was the replacement of all their windows and French doors.

“We originally wanted timber windows to suit the heritage of the property,” said Mr Prestwood, “but there was always that nagging doubt in the back of our mind about the maintenance of timber.

“So, we shopped around with various different companies who had various different products, but when we met with Starglaze, we knew that we’d found the company for us.

“I think they had the best product on the market for looks.

“They knew their products inside and out and rather than a ‘hard sell’, they listened to exactly what we wanted and offered us choices that they felt suited our requirements. There was no pressure – the choice was completely ours.”

The Prestwoods settled for a complete reinstallation of all their windows to a flush PVC-U casement, along with French doors, offering increased energy efficiency and durability without compromising on the classic style that they were after.

“Despite the rather decrepit central heating system that we had inherited in the new house, we noticed a significant improvement in the energy efficiency of the house as soon as the new windows were fitted,” said Mr Prestwood.

Sternfenster’s StyleLine range of flush casement windows comes with a WER of A as standard, with further enhancement available through the option of triple glazing. Double weather seals, low sightline gaskets and super spacer bars also ensure superb energy efficiency.

Additionally, StyleLine windows have no visible grooved corners, thanks to Sternfenster’s investment in modern Graf-welding technology.

Sternfenster’s customer tools and support initiatives also support installers. A virtual showroom enables installers to sit down with homeowners like Mr and Mrs Prestwood and visually show them the technical specifications, colour and hardware options, as well as a 360º CGI tour of products.

Sternfenster has invested heavily in IT solutions to facilitate a closer partnership with its customers. Central to this strategy is Sternfenster’s EasyAdmin system, which allows businesses to produce professional quotes quickly for homeowners. It also allows window installation companies to have complete oversight of their profit and loss. This information is updated daily and allows business owners to see the health of their accounts in real time.

“Our service offering means that for installation teams, like in the case of Mr and Mrs Prestwood, the installer can not only demonstrate the products in real time, using the Virtual Showroom, but can then produce a quick quote to show to the homeowner in a professional and easy-to-understand format,” Nathan said.

“Then if the quotation is converted into an order, EasyAdmin allows the installer to do this effortlessly, with the order tracking fully visible throughout the process.”

Once the order is placed with Sternfenster, a delivery tracking service allows customers to have greater visibility of their orders, and can even provide a delivery window, which reduces costly waiting times when teams could be out fitting.

“Time spent on site is expensive,” Sternfenster Sales Director, Nathan Court, said. “If our customers know that we will be arriving on site in a two-hour window, it allows them to plan their day productively, either by scheduling time on another job, or by finishing on site early. Time spent unnecessarily waiting is wasted profit, so we are putting money directly in the pockets of our customers!”

“We’d certainly recommend them to anybody,” Mr Prestwood concluded. “Everybody in fact!”
