Owning a terrace house can be incredibly rewarding, but it is not always roses.

They can be expensive to maintain and renovate.

Common problems with terraces include:

Subfloor Problems

Terrace houses often have problems in the subfloor.  Not necessarily structurally.

But being typically low to the ground creates several problems many homeowners are not aware of.

Damp and mold can creep up through the floor, staining wooden floorboards and presenting a health hazard.

Poor ventilation is another problem which terraces often suffer and can encourage pests such as termites and wood borers which can cause major damage if left uncontrolled.  Leaking plumbing can exacerbate these problems.

Small crawl space makes it difficult to access and treat problems without ripping up flooring.  In many Victorian and Edwardian terraces, the foundations are built up with piers isolating each room, making access more difficult.

Rising damp is a common issue of old buildings, but this is a particular problem for terraces.  Especially mid terraces moreso.  Fortunately there are new technologies which make treatment easier.

It can be difficult to treat with difficult access without ripping up a floor.

Structural Problems

Another often overlooked problem is that sharing a party wall can have its disadvantages.  If there are structural problems with the terrace next door, this may well effect others in the row.

Fire

Older terrace houses can be more susceptible to fire.  Old wiring can cause problems.
