It’s that time of year again — pumpkins on porches, fake cobwebs in the windows, and horror films on TV. But before you start hanging skeletons and string lights, there’s one place you might not want to look too closely…
👀 Your loft.
Because while you’re getting into spooky season, there could be something far scarier hiding up there.
The Ghost of Energy Past 👻
Old insulation is the ghost that never leaves. It’s thin, dusty, and quietly draining heat (and money) out of your home every single day.
If your loft insulation is older than your Halloween costumes, chances are it’s not doing much anymore. Modern standards call for around 270 mm of coverage, but we still find homes with barely 100 mm in place — or worse, patchy coverage where heat escapes through every gap. Result? Rising bills and a freezing winter ahead.
The Mould Monster 🧟♂️
Not all monsters make noise. Some grow in the dark, behind boxes and old decorations. If your loft suffers from poor ventilation or blocked airflow, moisture builds up and condensation begins — the perfect environment for mould.
Once it starts spreading across timber and insulation, you’re in real trouble. Mould doesn’t just smell musty; it can damage your roof and affect indoor air quality. We cover this in more detail in our guide to loft condensation in the UK.
The Foam Phantom 👻💀
Spray foam insulation might look harmless, but it’s the villain in disguise. It seals your roof so tightly that it can’t breathe, trapping moisture and slowly damaging timbers. To make things worse, many mortgage lenders will not proceed with homes that have spray foam installed.
If you’ve discovered spray foam in your loft, don’t panic — we remove it safely and thoroughly. Learn more about our spray foam removal service.
The Vampire Ventilation 🦇
You can’t see it, but poor ventilation is silently draining comfort from your home. When airflow is blocked — or worse, when spray foam has sealed off your eaves — moisture builds, timber decays, and insulation performance drops.
Good ventilation isn’t the enemy of warmth; it’s the balance that keeps your loft dry and efficient. We often restore this using Felt Lap Vents — a simple but powerful fix that lets air flow while keeping heat where it belongs.
The Exorcism 🔥
