Bricklaying & Repointing

Blocked Air Bricks

Anonymous user 16/03/2024 - 2.40 PM

We have recently moved into a 1930s Semi and have noticed that at the top of the house there are four blocked air bricks (two to rear two to the side). It looks like the holes have been filled with clear sealant. We are wondering if this is a cause for concern and do we need to potentially look at replacing the blocked bricks. There are a further 11 air bricks at the bottom of the property located at the rear, side & front of the property. We had a full buildings survey completed before purchasing the property and they dud not raise it to be an issue but it was flagged that four of the lower air bricks were partially blocked by decking that has been laid to the patio area at the rear of the property. We are looking to change the decking so are not overly concerned by this but we are experiencing lots of condensation issues and wondering if the blocked air bricks at the top of the property could be a contributing factor? Many thanks in advance for any advice.
