Deep clean and odour treatment in Streatham
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. If an indoor unit in Streatham drips from the front, a blocked drain tray is often the cause, which a deep clean clears.
A musty smell on start-up is the most common sign that an indoor unit in Streatham needs a deep clean. Streatham is about 5 miles from central London and falls within our London coverage. We cover SW16 and the streets around them.
Prices in Streatham
For Streatham, expect roughly £190 to £325 per indoor unit, VAT included, adjusted for typical London rates. That is above the UK middle, mainly because labour and access cost more in London. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down. Typical Two units work (deep clean of two indoor units on one visit) lands around £350–£595 in this area.
One unit
Deep clean of a single indoor unit.

Permissions
No planning or F-gas work is involved in a deep clean, though the engineer will tell you if the system shows signs of a refrigerant leak.
The visit
Before booking, tell us the make and model and what the system is doing. We confirm the visit price, then the engineer arrives with the right equipment and, where possible, the right parts. We agree the visit price before we come. On the day the engineer checks the system, carries out the agreed work and talks you through anything they find.
