old external air vent that was letting cold air hit the internal wall ❄️➡️🏠

That cold spot was causing condensation and localised damp, so we sealed it properly and repointed the surrounding area where the mortar had cracked 🔧

Small details like this make a big difference — warmer wall, no cold bridging, and helping prevent damp issues long-term 🙌

Next Stage – Ready for Finishing 🏁

Progress continues on this rising damp job in the dining room 💪

With the DPC injection complete, we’ve now moved onto the next phase — installing the membrane system and re-plastering. This will create a clean, dry barrier to protect the walls and ensure the damp issue doesn’t return.

Once finished, the space will be fully prepped and ready for the client to redecorate.

A proper step-by-step approach for a long-term solution ✔️

Before – Rising Damp Issue 🚧

This dining room was suffering from rising damp due to a high water table — causing moisture to travel up through the walls and damage the internal finish.

We’ve now hacked off the affected plaster to remove all contaminated material and carried out a DPC injection to stop moisture rising any further.

Next stage: membrane system and re-plastering to fully restore the space, ready for the client to redecorate.

Landlords & property managers — struggling with condensation and mould issues? 🏠

We’ve recently installed an Axi Heated PIV system designed specifically to tackle these common problems. By introducing a steady flow of fresh, filtered air (with a gentle heat boost), it helps reduce moisture levels and prevent condensation build-up — the root cause of mould.

It’s a low-maintenance, long-term solution that improves tenant comfort, protects your property, and reduces ongoing maintenance issues.

If mould and damp are becoming a recurring headache, this is well worth considering — contact us to find out more 📩

This porch area previously suffered with mould — a common issue in spaces with poor insulation and fluctuating temperatures. By installing IsoTherm, we’ve improved the thermal efficiency of the space, helping to reduce condensation and control moisture build-up.

The result is a warmer, drier porch and a long-term solution to help prevent mould returning 🙌

Great work by the team
