Pressure washing a driveway is one of the most cost-effective ways to dramatically improve the appearance of a property, removing years of ingrained dirt, algae, moss staining, and oil marks from concrete, tarmac, block paving, and stone surfaces. It is a service many homeowners use regularly, and understanding the typical costs helps in choosing and budgeting for professional cleaning.

What Affects the Cost

The main factors that determine the cost of professional driveway pressure washing are the size of the area to be cleaned, the type of surface, the severity of the soiling, and whether any additional treatments are applied. A simple concrete driveway that is lightly soiled is quickest and cheapest to clean. A heavily moss-covered block paved driveway that requires re-sanding of the joints after washing is more time-consuming and expensive.

Typical Price Ranges

For a standard single car driveway of around 20 to 25 square metres, professional pressure washing costs sixty to one hundred and fifty pounds. A double driveway of 40 to 60 square metres costs one hundred to two hundred and fifty pounds. Larger driveways and courtyards are priced accordingly, often at a rate of three to five pounds per square metre for straightforward work.

Surface Type

Block paving requires the most careful washing, as high pressure can displace the jointing sand between the blocks. After pressure washing, block paving should be re-sanded with kiln-dried jointing sand to restore the stability of the joints and prevent weed ingress. Re-sanding a double driveway after washing adds twenty to fifty pounds to the cost. Tarmac and concrete are more forgiving under high pressure and can generally be washed faster than block paving.

Biocide and Sealant Treatments

A biocide treatment applied before washing kills algae, moss, and lichen at the root, making removal easier and preventing rapid regrowth. Applying a biocide adds thirty to one hundred pounds to the service. A sealant applied after cleaning provides a protective barrier that repels water, oil, and staining and inhibits biological growth, extending the interval before the next cleaning is needed. Sealing a double driveway adds one hundred to three hundred pounds to the total service cost.

DIY Pressure Washing

Consumer pressure washers suitable for domestic driveway cleaning can be hired from tool hire companies for thirty to sixty pounds per day, or purchased from around one hundred to three hundred pounds for a reliable mid-range model. DIY cleaning saves the labour cost but requires time, physical effort, and appropriate safety footwear and eye protection. For regular maintenance cleaning, a domestic pressure washer is a practical investment that pays back over two or three uses compared with the cost of a professional visit.

Summary

Professional driveway pressure washing costs eighty to two hundred and fifty pounds for a standard double driveway. Biocide treatment and re-sanding of block paving joints add to the cost. A surface cleaner attachment produces more even results than a hand lance. DIY pressure washing with a hired or purchased machine is a cost-effective alternative for regular maintenance cleaning.
