Anna · Answer

The cost depends on:-
- Size of Area: A small terraced house may cost around £350–£500, while a detached house could range from £600 to £1,200.
-Level of Contamination: The presence of large volumes of guano, carcasses, and nesting material requires specialized, hazardous waste removal, increasing costs significantly.
-Sanitization and Odour Removal: Thorough cleaning, which includes disinfecting to prevent health risks from bird droppings, is essential and often added as a specialized service increasing the cost by a couple hundred.
- Accessibility: Difficult-to-access roofs will incur higher labour charges.
Each project is different and cost can be customisable.

Victoria · Answer

Cleaning out a roof void filled with dead birds, waste, and feathers typically costs between about £300 and £600  for a small domestic attic, but it can rise to around £800 to£1,500  or more for larger or commercial spaces, especially if the access is difficult. The cost depends on the extent of contamination, safety measures, and any proofing work you might need.

Alexandru · Answer

For a roof void filled with dead birds, droppings, feathers, and waste, this is treated as biohazard cleaning.

Typical cost in the UK:

Light–moderate contamination: £650 – £850
Heavy contamination: £900 – £1,200
Severe cases: £1,200 – £1,500+

The price usually includes removal of carcasses and waste, disinfection, odour treatment, and safe disposal.

Costs increase if access is difficult, contamination is heavy, or insulation needs replacing.

Expect around £900–£1,200 for most cases, but it can go higher if the situation is severe.

Terry · Answer

Basic loft/roof void clean (light contamination) £600 – £1,500 for a normal attic clean

Moderate contamination. Dead birds + droppings = biohazard territory

Roughly £800 – £2,000+ Often falls into “high hundreds to low thousands” for specialist cleaning.

Severe cases (heavily infested / long-term buildup) £2,000 – £4,000+ Especially if: Insulation is contaminated and needs removing Strong odour treatment (fogging/ozone) is required Large area or difficult access
