Price examples of facade impregnation
Single impregnation
If cleaning is not necessary because you have just become the happy owner of a newly built house, or your facade has already been cleaned, then you will obviously be the cheapest. The cost of just having an average facade of 60 m² impregnated is around £ 420. Consider an additional cost of around £10 to £22 per m². The total cost then comes to between £1,020 and £1,740. By leaving the cleaning to a specialist, you are always assured that your house is completely watertight.
Jointing, cleaning and impregnation
Is the pointing in need of replacement or would you like to make your house more attractive for a possible sale by also tackling the pointing? When replacing your grouting for a flat, smooth grout and impregnating the facade, you should expect to pay around £1,020 to £1,140.

What choices determine the façade impregnation costs?
There are a number of choices you have to make that affect the total price. Wondering what exactly these choices mean? Then read on.
Choice 1: Is cleaning necessary?
Before your facade can be impregnated, always check whether cleaning your facade is necessary. This is because if moss, graffiti or other dirt covers your facade, the impregnating agent cannot penetrate the pores of the stones. As a result, the agent will not work as well and you will not be able to enjoy your impregnated house for as long.
Choice 2: Replace grouting?
In addition to cleaning, it is also important that the grouting is in good condition. Bad grouting not only lets water through faster but can also cause damage to your facade. Replacing the joints will give your house a better look and prevent leakage.
Choice 3: What type of substrate is it?
Please check what type of substrate is involved beforehand. Wood needs a different treatment than stone. Especially if you are also having your facade cleaned, it is wise to tell us which surface you are dealing with. Sandblasting, for example, can be a very effective cleaning method, but is not suitable for every surface.
