1930s semis: big lofts, storage and squashed insulation
A 1930s semi often has a roomy loft that’s been used for storage for decades. That usually means flattened insulation and blocked eaves.

| Typical problems | Flattened insulation under storage |
|---|---|
| Watch for | Boards laid straight on the joists |
| Usual fix | Clear, remove or top up, raised storage floor |
What we usually find
Years of boxes on thin insulation, boards nailed straight onto the joists, and sometimes a bathroom fan blowing into the loft.
What we do
Clear the loft, replace or top up the insulation, fit a raised floor so storage doesn’t squash it again, and duct any fans outside.
