Driveway/ Patio Cleaning


Surfaces: Tarmac, Concrete, Cobblelock, Wood, Natural Stone

When we clean your driveway, you want it to look its absolute best for as long as possible. While power washing can provide immediate cleaning results, it will not take long for a driveway to revert back to its original state if the biofilm that causes the problem is not properly dealt with.

Biofilm is a term that describes the organic growth – moss, weeds, algae – that grows on hard surfaces. This is why we strongly recommend using a softwash chemical to eradicate the organic growth before pressure washing.

We are professional and trusted patio and driveway cleaners working in County Louth, Meath East, and Dublin.

Our Clean and Maintenance Options:

1 – Pre-Cleaning: We first sterilise and clean the unwanted organic material e.g. moss/algae and mould, often referred to as biofilm. We use a softwash chemical called Algoclear Pro to achieve rapid cleaning results. Algoclear Pro does not contain aggressive or oxidising agents such as bleach and is neither corrosive nor bleaching. Algoclear Pro is a powerful soap and when brushed and rinsed will remove grime from a surface as well as sanitising it.

2 – Surface Cleaner: Once the area has been pre-treated, we pressure wash using our 22-inch surface cleaner. This cleaning process is very efficient and produces outstanding results.

3 – Post-Treatment: We then protect the surface from re-colonisation by biological growth, through applying a residual-action biocide. This penetrates deeper into the surface, killing any remaining spores. This continues to provide active protection for the surface for up to a year or more. Without this protection, growth can return to a surface very quickly.

(For a perfect finish on cobblelock surfaces we will use sika sand).

N.B. if you are just looking for a quick clean of your driveway it is not necessary to complete all of the three steps above, but it is recommended for the best long-term results.


If after a few months from the day we cleaned your property you notice that it needs maintenance, we can call out and apply AlgoClear. This will ensure your patio and driveway will be looking great for longer and will save you from waiting and getting a bigger cleaning job done.

Please check out our pricing policy.


We will more than happy to call to your property to provide you with a free, no obligation quote and answer any questions you may have, so you can decide what type of cleaning will suit you best.


At Mullan External Cleaning building an ongoing relationship with our customer is important.

After we clean your property we want to keep it looking great.

Treatment with the biocide Algoclear Pro at the first sign of organic material returning will ensure we keep things under control.

We will check in with you 8/12 months after completing a job but if you notice any green returning in the meantime give us a call and we will be happy to help.

Remember that regular maintenance is much more cost effective than letting your property revert to needing a full cleaning service again.
