The Common Snag Affecting New Builds in the UK
When you look closely at the brickwork on a new build home. You will often notice small openings at the base of the wall or above windows. These are called weep holes, and they allow moisture inside the cavity wall to escape. They are a simple but essential part of a property’s drainage system.
At Home Snagging UK, we inspect hundreds of new build properties every year. Poorly pointed weep holes are one of the most common issues we record in our snagging reports. Although they may seem minor, blocked or incorrectly finished weep holes can lead to damp, staining and long-term damage.
Why Weep Holes Matter
Moisture naturally enters the cavity behind your external brickwork. Without working weep holes, that moisture becomes trapped. Over time this causes damp patches, peeling paint, mould and even structural deterioration.
A correctly installed weep hole should be open, unobstructed and clearly visible. When they are blocked by mortar or pointed over completely, they can no longer function.
Why Poorly Pointed Weep Holes Are So Common
Many new build homes are completed under strict deadlines. Small details like weep holes can be rushed or overlooked. We often see:
- Weep holes filled with mortar
- Weep holes that have been pointed over entirely
- Vents installed too close together or too far apart
- Weep holes missing above windows and doors
- Decorative brickwork hiding the openings
These small defects are often invisible to the untrained eye. However, they can lead to long-term damp problems that are expensive to fix if ignored. A home snagging report from a professional snagger can help to identify these issues.
How Poorly Pointed Weep Holes Affect Your Home
Without working weep holes, water cannot escape the cavity. This causes moisture to seep into internal walls. You may notice damp marks, bubbling plaster or a musty smell around affected areas.
Left untreated, this can escalate into more serious problems such as mould growth or even structural issues. For a brand-new home, this is something every buyer wants to avoid.

At Home Snagging UK, our professional inspections are designed to find these issues early. Our snagging reports include:

We couldn't be happier with the service we received. From my original enquiry which was dealt with so professionally, right through to our inspection which was incredibly thorough, and the inspector identified issues that we would never have spotted ourselves. Our report was sent through within 24 hours after the inspection...
FAQs
What does a poorly pointed weep hole look like?
It may be covered with mortar, blocked with debris or barely visible in the brickwork. Any obstruction that stops airflow or drainage is a defect.
Can I unblock a weep hole myself?
We do not recommend it. Removing pointing or mortar incorrectly can damage brickwork. Your developer should repair this as part of your snagging list.
Are poorly pointed weep holes covered by my warranty?
Yes. Builders are responsible for ensuring all weep holes are installed correctly and free from obstruction.
Will this cause damp inside my house?
It can. Trapped moisture inside the cavity often leads to internal damp issues if the problem is not resolved.
How do your snagging reports help?
Our reports highlight the defect with clear photographs and descriptions. Builders respond far faster when presented with professional evidence.
