We were invited to help a customer in South Manchester who had a very drafty floor in their kitchen diner. Their house was a Edwardian semi detached property.
The floorboards had been exposed and they were allowing cold drafts to penetrate into the living areas, making the room cold and almost unbearable in very cold weather. Some of the air bricks around the house had been closed off and there was a connection to the other half of the building.
We insulated the floor and added an air tight layer underneath to make sure that no drafts of cold air could get into the living areas. We added extra air bricks to make sure that the area under the floor was well ventilated.
The homeowner has since told us that the drafts have stopped and the room is far more comfortable than it was before we did the work.
