Older homes were often built to “breathe” — with open fires that needed a constant flow of air, so draughts through cracks, windows, and doors weren’t a problem. Today, those same draughts mean higher heating bills and a colder home.

Retrofit means upgrading your home’s fabric — insulation, airtightness, ventilation — so it holds onto heat, costs less to run, and stays comfortable all year, without losing what makes it special.

We’re approved contractors with Cosy Homes Oxfordshire, a retrofit advice service for Oxfordshire homeowners, and we carry out whole house “deep” retrofits — upgrading a home’s performance from top to bottom rather than fixing one thing at a time.

Depending on your home, this might include:

• Internal wall insulation using natural materials like woodfibre and lime plaster — a breathable option suited to older walls
• Insulating lime render (such as Diathonite) applied to external walls
• High-performance windows that keep heat in without changing a period property’s character
• Ventilation systems designed to keep air fresh once a home is made more airtight

Why trust us with it

Retrofit done badly can trap moisture and damage older buildings — it takes real expertise to get right. Nikki, our director, is an AECB CarbonLite graduate and is completing her Level 5 certification in Retrofit Coordination and Risk Management, so your project is planned by someone qualified in exactly this kind of work.
