But at what cost to the homeowner?
So, what are the risks and implications to your home?
A chance or imbalance in the moisture levels within the structure or enviroment can lead to extensive, costly complications to correct.
It is paramount before installing insulation to ensure a full appraisal of the property has been undertaken by a surveyor, who understands both the structure and the internal living enviroment and how the insulation will affect the building and what additional measures may need to be put in place.
The principle being that insulation must never be applied within or to a wall with defects in the underlying building fabric. This is hugely important, and we would urge homeowners to insist on a detailed pre-installation survey on the property by a suitably qualified surveyor before any insulation is applied.
Moisture related issues can come in many forms. Blocked cavities, defective pointing, guttering and high ground levels, which should never be overlooked. The risk of doing so can result in costly and highly damaging damp and timber decay which are hugely increased when underlying defects are ignored or covered up, by installing new layers which will prevent the structures drying down and in some cases introduce further water into the structure.
If you are considering taking up the government offer to install energy saving measures into your home through the Green Homes Grant, then have a survey undertaken beforehand and save your property turning green from mould!
