Case Study: Heritage Window Restoration in Swansea
Replacing Old PVC with Traditional Timber-Style Pvc Sash Windows
​
​Project Overview: Restoring Period Property Charm in Swansea, South Wales: This enquiry came through our website from homeowners in Swansea looking to restore the traditional character of their Victorian-era property. The existing windows were early-generation PVC units, around 25–30 years old, and had reached the end of their lifespan. The homeowners wanted to replicate the original wooden sash windows that had once defined the look of the house — using old photographs as reference.
​
Objective: Authentic Sash Window Replacement in Swansea: Our brief was to design and install high-quality timber-look Pvc sash windows that matched the original style and dimensions. Using detailed schematics and historical references, we aimed to provide a modern replacement that stayed true to the home’s heritage while offering improved performance.
The restoration and replacement window process
Process: From PVC Removal to Precision Timber-Look Pvc Sash Installation: We created detailed plans to replicate the original layout and proportions as closely as possible. The initial designs were close, but we made a few subtle tweaks on the second round, resulting in a design that worked even better than the original. The new windows retained the traditional appearance, while enhancing functionality and energy efficiency.
​
Health & Accessibility: Thoughtful Installation with Minimal Disruption: The customer’s wife has some mobility and health challenges, which we took into account throughout the project. Our team ensured a low-impact, hands-off installation process that required no involvement from the homeowners. The work was completed efficiently and respectfully, with minimal disruption.


The Result: Period-Style Sash Windows with Modern Benefits in Swansea
The final result is a seamless blend of classic design and contemporary performance. The property now features stunning timber-style Pvc sash windows that reflect its original heritage — while benefiting from modern materials and insulation standards. The homeowners in Swansea were thrilled with the transformation.
