In short: Bearing, dampness and ventilation under an older Box Hill house.

Why we go under

On an older house the subfloor carries the evidence: how the structure is supported, whether it is dry, and whether anything has been altered.

What we recorded

Subfloor bearing in question at several points, beams needing assessment and persistent dampness through the substructure.

Why dampness matters twice

It is a durability problem for the timber and it is the principal conducive condition for termites, which is why we book building and pest together on these properties.

Ground clearance

Masonry cladding sitting too close to the adjacent ground bridges the gap the clearance existed to provide.

When we cannot get under

Where access is sealed, too tight or unsafe, the report says the area was not inspected and why, rather than passing over it.

FAQ

Questions Box Hill owners ask about this

Does the inspection go under a deck?

Yes, so long as it is safe to get in. Where the space is enclosed or too shallow, the report records it as not accessed.

Is dampness always serious?

Not always, but it is always worth understanding, because it points at drainage or ventilation that can usually be improved.

Can bearing be fixed?

Usually, by repacking or adding support. What matters is knowing before you buy rather than after.

Should I get building and pest together here?

On an older Box Hill property with a subfloor, we would.
