About

About Plainwater

We bring tired driveways, patios and render back to how they were first laid. Over 1,800+ surfaces restored so far, from mossy town courtyards to long country drives, every one tested first by a small crew who set the pressure to the stone, and never the other way round.

Services

What webring back

Five surfaces, one rule. We test a patch first, then clean at the pressure the material can take, not the pressure the machine can give.

  1. (01)

    Driveways

    Block paving, tarmac and resin brought back to one even colour. Weeds out of the joints, oil and tyre marks lifted, sand brushed back in.

    • Rotary surface clean
    • Oil and tyre marks treated
    • Joints re-sanded

    Patios and stone

    Sandstone, limestone and porcelain cleaned at the pressure the stone can take, then sealed if it needs protecting from the next winter.

    • Test patch first
    • Black spot lichen treated
    • Optional breathable seal

    Roofs and gutters

    Moss removed by hand and soft wash, never a jet straight at the tiles. Gutters cleared and downpipes checked while we are up there.

    • Hand scrape and soft wash

    Decking and fences

    Hardwood and composite cleaned back to the grain, then oiled or stained so it does not turn green again by spring.

    • Grain-safe pressure
    • Anti-slip treatment
    • Oil or stain finish

Job 01 / 04

Four steps,no shortcuts.

  1. Free, about 30 minutes

    01. Thesurvey

    We walk the job with you, identify the stone and check anything nearby that water could hurt. Written quote within 48 hours.

  2. Before we touch the rest

    02. Thetestpatch

    A small hidden corner first, at low pressure. We see how the surface reacts and get your sign-off before going any further.

  3. Usually done in a day

    03. Theclean

    Rotary cleaner for flat stone, soft wash for render and roofs. Pressure set to the material, never to what the machine can do.

  4. 12-month check-in

    04. Theseal

    Joints re-sanded, sealed if the surface needs it, and we come back after a year to check it is holding up.

Beforeyou book.

The six things people ask us before a first job. If yours is not here, send us a photo and ask.

Not the way we do it. We identify the stone, run a test patch at low pressure and only go as high as the surface allows. Sandstone and render get a soft wash, never a blast.

Low pressure first · Soft wash for soft stone

Usually not. The van carries its own water and a petrol machine, so all we need is access. On longer jobs we might ask to top up from an outside tap.

Self-sufficient van · No extension leads

Most patios and drives stay clean for two to three years. A biocide treatment slows regrowth, and sealing porous stone buys more time again.

Biocide included · Sealing on request

We cover beds and lawn edges, rinse plants before and after, and keep dirty water away from drains wherever the council asks us to.

Plants protected · Run-off controlled

Only for the survey and to sign off the test patch. After that we just need side access and somewhere to park the van.

Access is enough

Yes. We are fully insured for public liability, and the certificate comes with every written quote.
