Question 1

What surfaces can you pressure wash?

Accepted Answer

We pressure wash driveways, patios, paths, decking, block paving, concrete and most hard external surfaces, lifting away ingrained dirt, grime, algae and weeds. For more delicate surfaces such as render or roof tiles we switch to soft washing to avoid damage. We assess each surface first and choose the right method for it.

Question 2

What is the difference between pressure washing and soft washing?

Accepted Answer

Pressure washing uses high-pressure water to blast dirt off hard, robust surfaces like driveways and patios, while soft washing uses low pressure and cleaning solutions for delicate surfaces such as render, cladding and roofs. Using high pressure on the wrong surface can cause real damage, so we match the technique to the material. We carry both so your property is cleaned safely.

Question 3

How much does pressure washing cost?

Accepted Answer

Pressure washing starts from GBP149, with the final price based on the size and condition of the area being cleaned. A small patio costs less than a large driveway with heavy moss and weeds, so we provide a free, no-obligation quote after seeing the area. There are no hidden charges.

Question 4

Will pressure washing damage my driveway or patio?

Accepted Answer

When done correctly it will not, but pressure washing in the wrong hands can dislodge jointing sand, pit soft paving or strip pointing. Our team adjusts the pressure and technique to suit your surface, and we re-sand block paving joints where needed. This careful approach protects your driveway while still getting it properly clean.

Question 5

How often should I have my driveway pressure washed?

Accepted Answer

Most driveways and patios in Belfast and Northern Ireland benefit from a clean once a year, as our damp climate encourages algae and green growth to build up quickly. Shaded or north-facing areas may need more frequent attention. Regular cleaning keeps surfaces safe and stops slippery algae taking hold.

Question 6

Can you remove algae and slippery green growth?

Accepted Answer

Yes. Algae and moss are a major cause of slippery driveways and patios in Northern Ireland, and pressure washing removes them along with the dirt holding them in place. We can also apply a treatment to slow regrowth where required. The result is a safer, cleaner surface that looks far better.

Question 7

Are you insured for pressure washing work?

Accepted Answer

Yes. We hold GBP10 million public liability insurance, and our team is PASMA certified and IPAF trained, so you are fully covered on every job. With more than 30 years of property maintenance experience, we work to professional safety standards throughout. That gives you complete peace of mind.

Question 8

Which areas do you cover for pressure washing?

Accepted Answer

We serve Belfast, Newtownabbey, Bangor, Lisburn and across Northern Ireland, including Ballymena, Antrim, Newry and Armagh. If you are not sure we cover your area, just ask and we will let you know. Most enquiries get a response within 24 hours.

Question 9

Do I need to be home for pressure washing?

Accepted Answer

No, you do not need to be present, as the work is carried out outside. We do need safe access to the area being cleaned and usually an outdoor water supply. Many of our customers across Belfast leave us to it while they are at work.
