Pressure washing removes years of dirt, algae, moss, and grime from driveways, patios, walls, decking, and building exteriors. In Ireland's damp climate, algae and moss growth are relentless, particularly on north-facing surfaces and in shaded areas. A single pressure washing session can make a ten-year-old driveway look new again.
The most common residential pressure washing jobs are driveways, patios, garden paths, decking, exterior walls and render, and roof tiles. Each surface requires different pressure settings and techniques: too much pressure on soft stone, timber, or render causes damage, while too little pressure on concrete or block paving does not remove stubborn staining.
Professional pressure washing delivers significantly better results than a consumer machine from a DIY store. Commercial machines operate at 150 to 250 bar (compared to 100 to 130 bar for consumer models), with higher water flow rates that clear surfaces faster and more thoroughly. Professional operators also apply treatments after washing (moss inhibitors, sealants) that extend the clean appearance for 2 to 3 years.
Comparing quotes from experienced pressure washing contractors ensures your surfaces are cleaned safely and effectively without damage.
How Much Does Pressure Washing Cost in Ireland?
Typical pricing for pressure washing services in Ireland (2026):
| Service | Typical Cost | Notes |
|---|---|---|
| Driveway (40 sq m) | €150 | €300 | Surface type, condition |
| Patio (20 sq m) | €100 | €200 | Surface type, condition |
| Building exterior | €200 | €500 | Height, access, area |
Pressure washing is typically priced per square metre or as a fixed price for specific areas (e.g., driveway, patio). Size, access, the level of contamination, and the surface type all affect pricing. Post-wash treatments (moss inhibitor, sealant) are usually quoted as extras. Dublin rates are marginally higher due to travel and disposal costs.
What to Expect: The Pressure Washing Process
- Assessment of surfaces and contamination level.
- Pre-treatment with cleaning solutions for heavily soiled areas.
- Pressure washing at appropriate settings for each surface type.
- Post-wash treatment (moss inhibitor, sealant) if requested.
- Clean-up and drainage check.
Common Mistakes to Avoid
- Using maximum pressure on every surface. This strips render, damages soft stone, and splinters timber.
- Not re-sanding block paving after washing. Pressure washing removes jointing sand, leading to weed growth and block movement.
- Pressure washing a roof without experience. Roof tiles can be cracked or displaced. Roof cleaning should only be done by experienced operators with proper access equipment.
- Ignoring the wastewater. Chemical-laden runoff should not enter storm drains.
- Not applying post-wash treatment. Without moss inhibitor, algae regrows within 6-12 months in Ireland's climate.
What to Look for When Hiring a Pressure Washing Professional
Always check that your chosen professional is properly insured and has relevant experience for your specific job.
Questions to Ask Your Pressure Washing Professional
- What pressure setting do you use for my surface? Different surfaces need different pressures. Too high damages render, timber, and soft stone.
- Do you apply a post-wash treatment? Moss inhibitor keeps surfaces cleaner for 2-3 years.
- Are you insured? Pressure washing can damage surfaces, break windows, and affect neighbouring properties.
- How do you handle wastewater? Wastewater containing cleaning chemicals should not run into storm drains untreated.
- Will you re-sand block paving joints afterwards? Pressure washing strips jointing sand from block paving. Re-sanding is essential to prevent weed growth.
- How long until I can use the area? Patios and driveways can be walked on immediately. Sealants need 24 hours to cure.
Frequently Asked Questions
Driveway (50 m2): €150 to €300. Patio (30 m2): €100 to €200. Full house exterior: €300 to €600. Decking: €100 to €250. Post-wash sealant adds €3 to €6 per m2. Most operators have a minimum charge of €100 to €150.
Once a year for most Irish driveways. North-facing or shaded surfaces may need it every 6-12 months. Applying a moss inhibitor after washing extends the clean period to 2-3 years.
Yes, if done incorrectly. Too much pressure strips render, damages soft stone, splinters timber, and erodes pointing between blocks. An experienced operator adjusts pressure for each surface.
Consumer pressure washers work but take 3-5 times longer than commercial equipment and do not achieve the same depth of clean. A professional does a typical driveway in 2-3 hours; a consumer machine takes a full day or more.
Sealing block paving after washing protects it from staining, reduces moss growth, and enhances colour. It adds to the cost but extends the clean appearance. Sealant lasts 3-5 years.
