If you've ever wondered what a weep vent is and questioned why you might need one, we have the answer to what this smart little device can do for your home.

If you live in an older home you’re unlikely to see weep vents in your brickwork. If you live in a new build, however, they are a standard addition. Why? Because they help remove water and keep a wall dry. But don’t panic if your exterior walls don’t have them.

The perfect time to retrofit weep vents would be when repointing brickwork. But if you have no plans to do this, call in a builder to find what you need and how much you can expect to pay.
