Pricing: roof, facade, window and paving cleaning

Why a price per metre tells you little on its own

The lowest price per metre becomes the most expensive one when the work has to be repeated a year later. On facades and roofs, the difference between a wash and a treatment against algae regrowth is several years of durability, even though on paper it is the same line item.

So when comparing quotes, look at what is included: substrate preparation, travel, securing the work area, waste disposal, and whether the price changes when more work turns up on site.

Roof cleaning and roof coating prices

Roof cleaning is charged per square metre of roof, and the main price drivers are the pitch, the type of covering and how deeply the moss has taken hold. Concrete tiles behave differently from clay, and sheet metal is cleaned differently from fibre cement.

Roof coating and impregnation are separate items that follow the cleaning. The covering has to be clean and dry before coating, so the price always includes that preparation. On a metal roof, anti-corrosion preparation is added.

Facade cleaning and facade painting prices

The price of facade cleaning follows from the area, the height and the surface. The decisive question is whether controlled water pressure is enough or whether a chemical treatment against algae is needed, which extends how long the result lasts.

Facade painting is charged per square metre and the rate covers substrate preparation, priming and the coating itself. Local repairs and joint sealing are instead priced per linear metre, because the work covers a specific crack or joint rather than the whole wall.

Window cleaning prices

Window cleaning is charged per square metre of glass. The price depends on whether the work can be done from inside, from a telescopic pole or needs rope access, and on whether frames, sills and blinds are included.

For residential and office buildings it is worth asking for a regular service rate. Repeat cleaning costs less per metre than a one-off, because the setup and survey are not paid for every time.

Lightning conductor and core drilling prices

A lightning conductor is not priced per metre but by the extent of the system, meaning the number of air terminals, the length of the down conductors and the earthing method. We price the installation work carried out by rope access; the inspection and testing is performed and charged separately by a certified technician.

Core drilling is charged per penetration, with the price set by the bore diameter, the thickness of the structure and the material being drilled.

Bird barrier prices

Pigeon spikes are charged per linear metre of protected ledge, netting per square metre of closed opening. The price always includes cleaning and disinfecting the surface first, because a barrier is never fitted over droppings.

How to get an exact price

Photos are the fastest route. Take a shot of the building from a distance so the height and access are visible, then a close-up of the area to be treated. Add rough dimensions and the floor level. On that basis we can usually prepare a no-obligation quote within 24 hours.

For larger jobs and apartment blocks we come for a site survey. The survey is free of obligation and it also keeps items out of the quote that your building does not actually need.

Apartment blocks and the repair fund

For managers and owners' associations we prepare the quote in a form you can put to a meeting or a written vote, itemised by scope. Work on the common parts of a building is usually paid from the repair fund.
