Cleaning brick walls?
The main reasons for cleaning your walls are to remove some of the following stains
Organic staining– The Walls may have turned green with algae contamination
Cement Staining– Walls are often stained with cement splashes or building dust during building work. Scaffold rash is where layers of building dust and staining can be seen on the brickwork where the scaffolding levels were erected alongside the brickwork. This can be very visible after the scaffolding comes down and the bricks need to be washed down.
Carbon staining– Also referred to as atmospheric pollution, this is where bricks turn black in colour on the face of the brick due to pollution staining.
What to look for when choosing a brick cleaning contractor
When choosing a brick cleaning contractor it’s important that you choose a professional, experienced company.
You want to ensure they use the correct cleaning methods and do not just blast the brickwork with high pressured water which will damage the bricks and pointing.
Look for evidence of previous jobs and examine before and after pictures or ask for references from previous jobs.
Ensure the company has the correct liability insurances
If using acid or chemicals to remove staining such as carbon or cement staining ensure that the operators are COSHH trained and use chemicals or acids safely.
How much is brick cleaning?
Brick cleaning can start from as little as £2+vat / Square metre for large commercial projects. This is when there are multiple plots to wash and there is a clear run of work.
Domestic projects, where the size of the job is much smaller prices from around £10+vat/ square metre.
There are several factors which influence the cost which include;
- The size of the job
- Access to water and power
- Whether any chemicals are required to achieve desired outcome (what stains need removing)
- Access – Is direct access from scaffolding available or is there need for telescopic equipment or a cherry picker to access the cleaning area?
