Im beginning to think that a previous owner of my flat has had the airbricks at the front of the house rendered over. Other houses of the same style in the street have air bricks either side of the bay window and are easily seen as they don't have the external render. Would it be reasonable to assume as the other houses have them then I would too. House was built around 1900 and as it's end of terrace there are air bricks along the side just not at the front. How would I go about searching for if they are there or not? I've tried tapping the render but cant hear any difference in sound and I've measured to where the internal floor level is by using the window sill as a gauge but still cant locate them?
Any thoughts?
