I have a 1930s semi-detached house that has rendering on the outside. I am unsure if the house is solid wall or a cavity wall. The brick pattern in the garage isn't like the images I have seen of solid wall i.e. the bricks aren't one width ways and one length ways. Also, below the rendering there are about 4 layers of exposed brick and these seem to be the cavity wall method of laying too.
The reason for the question is when we bought the house the surveyor said that due to the wall thickness it was likely to be solid wall but it didn't say for sure it was. Also, when I drilled through the wall to put a TV cable through it felt like the drill went through a gap.
Is the gap just smaller on 1930s houses compared with modern construction?
Thanks Marc

Think twice before installing cavity wall insulation.
I'm not for one moment saying don't do it - but please be certain that it will work for your home. Do not rush into a decision without all the facts. Cavity sizes do vary on older properties and it may be that not all types of insulation are suitable for your property, so you need to be sure that if you do go ahead that you are getting the right stuff.
Poorly installed insulation or insulation in a home not suitable to receive it is worse that no insulation...and putting the insulation in is far easier than getting it out again.
Some less reputable firms send out surveyors who are no more than salesmen. Ask friends and neighbours for recommendations, and get several quotes.
I would draw you attention to this article about people who have experienced problems.
