Another job completed recently and this one’s a good example of why doing things properly matters.

After removing the old fibreglass insulation, we found old boarding hidden underneath 🥴 This had to be completely stripped out, as it was creating an air gap between the ceiling and the insulation.

That gap might not seem like a big deal, but it reduces how effective the insulation is and can lead to heat loss.

Once everything was cleared out properly, we installed fresh 300mm Knauf insulation to current standards — making sure it’s doing the job it’s supposed to ✔️

Sometimes it’s what you don’t see that makes the biggest difference.

If you’re unsure what’s going on in your loft or think your insulation might not be performing as it should, feel free to get in touch for a free quote or advice 👍

We recently insulated this ceiling in Lancing, helping the homeowner keep the heat in and reduce energy bills 🔥🏠

Proper ceiling insulation makes a huge difference — warmer rooms, lower heating costs, and improved comfort all year round.

If you’re in Lancing or surrounding areas and your home feels cold upstairs or heat escapes too quickly, it might be time to upgrade your insulation.
