Basements and cellars
A Victorian coal chute still opens into the front wall of the cellar. What water path does that chute keep that a blocked air brick does not?
Not the same path as a blocked air brick: the Victorian coal chute still opens into the front wall of the cellar and keeps that opening. A chute is a route from the front, where coal once came in, into the cellar. Water from the pavement or the front area can use that opening. A blocked air brick is a ventilation hole that is obstructed. It is a different element. The chute does not become an air brick because both are in the front wall, and the air brick does not describe the chute.

What is the fuller explanation?
Older cellars often have several openings that get lumped into one damp sentence. That loses the path. The chute is a larger, purpose-made opening through the front wall. Even if an air brick nearby is blocked, the chute remains its own way in. Even if the air brick is clear, the chute is still there. The survey should say the chute opens into the cellar, where that was seen, and say separately what the air bricks are doing. One note must not swallow the other.
Do not fill the chute and call it the same job as clearing an air brick. Ask the surveyor which opening they saw: the chute, the air bricks, or both, and whether either showed staining. If water is the worry, the chute is the path a blocked ventilator does not stand in for. Keep any later work matched to the opening it concerns. The home survey has distinguished an open coal chute from a blocked air brick.
What should you ask your surveyor?
- Did you see the coal chute open into the front wall, as its own opening?
- Are the air bricks written separately from that chute?
- What staining, if any, was at the chute rather than at a ventilator?
What are the typical next steps?
- Describe the coal chute as its own opening into the cellar.
- Do not merge it with a blocked air brick.
- Match any later work to the chute or the air brick, not to both at once.

Also asked about this
If the chute has a board over it, has the path gone?
Not necessarily. A board is a cover the survey may have seen. It is not the same as an air brick, and it may not stop water using the chute.
Does a clear air brick cancel the chute?
No. A clear air brick only ventilates. The coal chute still opens through the front wall of the cellar on its own path.
