SUPERHOMES: Mr & Mrs Zimmer, Smethwich, Birmingham

PROJECT SPECIFICATION:
The installation of 11 casement windows, 1 bay window, 1 bay window/door combination and 1 single door combination.

“We really wanted to retain the character of the building, so the option of having a black door against a Rosewood frame was very important to us, as it matches the house’s original materials. We feel like we’ve achieved the best of both worlds – a sympathetic design that keeps the building’s integrity but combined with all the modern benefits of a Superhome.”

SECURITY UPGRADE SUMMARY


Following installation, the property’s security score increased from 75 to 142, representing a 67-point improvement or an 89.3% uplift in overall security. This was driven by replacing vulnerable timber frames with the Finesse standard, making the home significantly more resistant to forced entry.

“The old timber windows always felt like a bit of a weak point, especially when you hear about crime rates in the area. Seeing our security score practically double gives us real peace of mind.”

ENERGY EFFICIENCY UPGRADE SUMMARY


The property improved by 3 EPC points (from 55 to 58) following installation. Annual CO₂ output has reduced from 5.1 tonnes to 4.7 tonnes, a 7.8% improvement, demonstrating the impact of upgrading from drafty timber to our A-rated glazing system.

“Getting rid of those old frames was a must, and knowing the new Finesse windows will save us the equivalent of a month’s heating bills every year is brilliant.”

PROPERTY VALUE UPGRADE SUMMARY


The home was independently valued at £310,000 prior to installation and £325,000 following completion, a £15,000 increase (4.8% uplift). Against an installation cost of £17,990, the majority of the investment was immediately locked back into the property’s equity..

“It’s a great feeling to know that the money we spent hasn’t just vanished—it’s essentially gone straight back into the value of the house.”

“We couldn’t be happier with the whole investment. Visually, the new windows are a massive improvement over what we had before, it changes the whole look of the house. We originally found Finesse on a Google search and checked out all the reviews against other companies. It’s great to see that the actual experience lives up to what everyone else says online.” Mr & Mrs Zimmer
