Deep clean and odour treatment in Maidenhead
In the South East, loft rooms and glazed extensions can climb well above the outside temperature on a sunny afternoon. If an indoor unit in Maidenhead 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 Maidenhead needs a deep clean. Maidenhead is about 12 miles from Reading and falls within our Berkshire coverage. Postcode districts we cover here include SL6.
Prices in Maidenhead
Our South East England guide price for a deep clean and odour treatment is £175–£300 per indoor unit, VAT included. South East England is one of the dearer parts of the UK for trades, which shows in the range. The price depends mainly on how many indoor units need cleaning and whether the fan and coil need a full strip-down. For reference, the Two units option in Maidenhead (deep clean of two indoor units on one visit) usually comes to about £325–£545.
One unit
Deep clean of a single indoor unit.
Two units
Deep clean of two indoor units on one visit.
Clean and service
Deep clean plus a full service of the system.
Permissions
A deep clean does not touch the refrigerant circuit and needs no permissions. If the engineer finds a refrigerant problem, it is explained and priced separately before anything is done.
The visit
A photo of the indoor unit's label and a short description of the problem help us price the visit accurately and bring what is likely to be needed. 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.
