The DALPEST team recently took on a rather unusual (and messy!) challenge after being called to a windmill that’s due to be lovingly restored.

A Unique Challenge
Before any restoration could begin, there was one major issue to tackle: years’ worth of pigeon guano had built up inside of the structure.
As you can imagine, pigeon droppings aren’t just unpleasant, they can also pose serious health risks and cause long-term damage to buildings. It was essential to get the space cleaned and safe prior to any further works taking place.
Why Pigeon Guano Is a Problem
Guano (pigeon droppings) might not seem like a big deal at first glance, but it’s far from harmless. Over time, it can:

- Corrode stone, metal, and wood surfaces
- Contaminate the air with harmful spores that can cause respiratory issues
- Create unsafe, slippery conditions for anyone entering the area
That’s why professional removal and disinfection are always necessary. It’s definitely not something you should attempt yourself!
Restoring the Windmill to Its Former Glory
Our technicians spent several days carefully removing the buildup and sanitising the interior to ensure it was completely safe. Once the clean up was complete, we also proofed the structure, sealing entry points and installing deterrents to prevent the pigeons from returning.
This resulted in a clean, safe and pest-free windmill that’s now ready for restoration. We’ve included before and after photos showing just how much of a transformation it was!


Protecting Your Property from Pigeons
Pigeons may be a part of everyday life, but when they start nesting in buildings, they can quickly cause costly damage. If you’ve noticed droppings, nesting materials, or constant cooing around your property, it might be time to act before the problem grows.
DALPEST provides:
- Safe guano removal and disinfection
- Bird proofing and deterrent installations
- Tailored pest control plans for homes, businesses, and heritage sites.
