Semi-Detached House
Usual House Features
These homes are almost always built with a cavity wall system with 50mm of insulation between the blocks and 100mm of insulation in the attic. Many homes would have upgraded their insulation levels in the meantime, by pumping the cavity wall and adding insulation of 200mm in the attic. The original windows provide medium insulation value but were likely installed without airtightness being a priority. The floors are typically solid concrete, with medium levels of insulation underfoot, and typically heated with a gas boiler.
What Our Survey Will Look At
Homes built in this period will have windows coming towards their end-of-life, if they have not yet been upgraded. Our surveyor will examine this, as well as the quality of external doors and the general levels of draughts throughout the home. We will also check your home’s insulation standards, to detect potential wall or attic insulation upgrades. A thorough assessment of your heating system gives us the platform to design a ultra-efficient heat pump solution, tailored to your home. We will also assess your roof, to design a Solar PV solution that maximises your solar potential.
Typical Costs & Grants
Retrofit costs will depend on the condition of your windows and doors. If they have not been upgraded already, this is now the time that many people will consider upgrading to triple-glazed standard. If windows have been upgraded already, we will focus on heating system efficiency through a heat pump, as well as insulation improvements and major cost savers like solar PV.
