Patio Cleaning Cost: What Shapes the Price

Written by Jordan Sartain, owner of OOR External

Last updated:

Patio cleaning cost is shaped by the patio itself: the material, how it is jointed, how much black spot and algae it carries and how easy it is to reach. Two patios of the same size can be priced very differently. This guide explains why, so you can compare patio cleaning prices fairly.

Material

Natural stone such as Indian sandstone needs low pressure and patient treatment, which takes longer than cleaning concrete slabs. Porcelain is quicker to clean but needs care at edges and joints. Slate, limestone and reconstituted stone each have their own needs. Knowing the material helps a quote reflect the right method.

Jointing

Patios may be jointed with sand, mortar or resin compound. Sand joints are refilled after cleaning, adding materials and time. Mortar and resin joints are checked before cleaning because they can wash out if loose, and repairs are a separate matter. The condition of the joints is often a bigger factor than the slabs.

Black spot and algae

Black spot lichen and green algae are common on patios, especially in shade. Treating black spot properly means applying a product and allowing dwell time, sometimes with a follow-up. That adds to the cost compared with a simple wash, but it is what actually deals with the spots.

Garden access

Once the patio has been cleaned, keep leaves clear of the slabs and drainage channels. Note where water remains after rain, and distinguish a drainage problem from staining that needs cleaning. Existing surface coatings should be identified before the work, rather than assuming all slabs tolerate the same method. Describe the whole patio in photographs, including steps and edges, so the quotation covers the surfaces you actually want cleaned.

Most patios are in back gardens. Access through a side gate is simple; carrying equipment through a house or down steps takes longer and needs floor protection. Water supply, power and where runoff will go are part of the plan. Plants, ponds and lawns around the patio are protected during treatment.

  • Steps and level changes
  • Water supply and drainage
  • Plants, ponds and lawns nearby

Comparing patio cleaning prices

Some quotes cover a jet wash only. Others include black spot treatment, joint work and a tidy-up. A cheaper quote that skips treatment may leave black spots in place or bring algae back quickly. Compare the method, the products and what happens to the joints. For driveways, the driveway cleaning cost guide covers the factors specific to those surfaces.

Size and layout of the patio

Area still matters. A small courtyard patio behind a terrace takes far less time than a large patio that wraps around a house. Steps, raised beds, retaining walls and paths leading off the patio add to the work, as do slabs laid around ponds or water features that need protecting. Measure roughly or count the slabs, and mention any areas you want included or left out.

First cleans and maintenance cleans

A patio cleaned for the first time in years carries more growth and staining, so it takes longer than a patio cleaned regularly. Black spot in particular builds up over several seasons. After a thorough first clean, lighter maintenance visits keep the surface in good condition. If you are preparing for a garden party, a house sale or new furniture, mention the date so the work can be timed.

Furniture, pots and garden features

Tables, chairs, heavy planters and barbecues need moving before cleaning. Say whether you can clear the patio yourself or need help, and mention anything too heavy to move. Rust marks under metal furniture and rings under plant pots are common and may need their own treatment.

Frequently Asked Questions

How much should patio cleaning cost?
It depends on the material, jointing, black spot treatment and access. Compare what each quote includes rather than only the headline figure.
Is black spot treatment included in a patio clean?
Not always. Ask whether a lichen treatment is included, as a wash alone rarely removes black spot.
