Professional Patio Cleaning Services You Can Trust

At A&R Roof & Hard Surface Cleaning & Restoration, we provide expert patio cleaning services that restore the appearance and usability of your outdoor living space. A clean, well-maintained patio not only enhances the overall look of your garden but also creates a safer, more inviting space to enjoy with family and friends throughout the year.

We proudly serve Harpenden, St Albans, Rickmansworth, Milton Keynes, Dunstable, Radlett, Watford, Berkhamsted, Hemel Hempstead, Welwyn Garden City, and all nearby towns and villages. Our team is fully trained and accredited in hard surface restoration, giving you a professional patio cleaning service you can rely on.

A&R cleans all types of patio surfaces, including block paving, natural stone, flagstone, and porcelain, using methods such as patio paving cleaning, patio pressure washing, patio jet washing, and patio softwashing. Each surface type requires a different technique, and because our team is trained and accredited in hard surface restoration, we assess your patio before work begins to ensure the correct process is used for your specific surface.

If you’d like to protect your surface once it’s clean, our patio sealing services offer a longer-lasting finish and slow down regrowth of moss and algae.

What a Professional Patio Clean Involves

A typical visit starts with clearing loose debris and weeds from the joints, followed by a biocide application to treat algae, moss, and lichen at the root rather than just on the surface. Once that treatment has had time to work, we carry out patio pressure washing to lift dead growth and ingrained dirt, then re-sand the joints where needed. This sequence – treat, dwell, wash, restore – is what separates an outdoor patio cleaning service from a quick pressure wash, and it’s the same process our technicians follow on every job.

Why the Order of Steps Matters

  • Pressure washing before treating growth removes the visible mark but leaves spores behind, so staining often returns within weeks.
  • Skipping the biocide dwell time means the treatment doesn’t fully penetrate moss or algae roots.
  • Re-sanding joints afterward protects against weed regrowth and helps the paving settle correctly.

Why Choose A&R as Your Local Patio Cleaners

Neglected patios can fade, stain, or suffer from organic growth over time, and replacing paving outright is rarely necessary if it’s maintained properly. As a patio cleaning business built on hard surface restoration, we save customers the cost of replacement by treating the surface correctly the first time. We also offer combined driveway and patio cleaning visits, since both areas tend to build up moss and grime at a similar rate – worth considering if you’re comparing local patio cleaners and want the most cost-effective option for a full outdoor clean.

If you’re searching for patio cleaners in my area, it’s worth checking that whoever you choose is insured, trained in biocide application, and willing to explain their process upfront rather than just turning up with a jet washer. That’s the standard we hold our own team to on every job.

  • Site assessment to identify your paving type before any work begins
  • Debris and weed clearance from joints
  • Biocide treatment to target algae, moss, and lichen at the root

Frequently asked questions - Patio Cleaning Services

How often should I get my patio professionally cleaned?
Most UK patios need a deep clean once or twice a year, depending on how shaded the area is and how much foot traffic it gets. Patios under trees or in damp, north-facing gardens tend to attract algae and moss faster, so twice-yearly cleaning keeps them looking their best. A professional patio cleaner can advise on a schedule based on your specific type of stone or paving.
A domestic pressure washer can lift surface dirt, but it often can’t remove ingrained algae, moss spores, or oil stains sitting deep in the pores of natural stone or block paving. A professional patio cleaner uses commercial-grade equipment and the correct pressure settings for your specific surface, so you get a thorough clean without damaging the pointing or the stone itself.
Not if it’s done correctly. Too much pressure, or the wrong nozzle, can strip sand from joints or etch softer stones like sandstone and limestone. This is why an outdoor patio cleaning service should always assess the paving type first and adjust the pressure accordingly, particularly for older or more delicate surfaces.

Yes. Most of our customers want their driveway and patio cleaned in the same visit, since both areas suffer from the same buildup of moss, algae, and grime. See our driveway cleaning services for more detail, booking both together also tends to work out more cost-effective than arranging two separate visits.

Yes, patio tile cleaning is one of our most requested services, especially for porcelain and ceramic outdoor tiles, which show algae and black spot staining quite visibly. We adjust our methods depending on whether you have porcelain, sandstone, limestone, or concrete block paving, since each surface responds differently to pressure and cleaning agents.
A typical visit starts with clearing loose debris and weeds from the joints, followed by an application of biocide to treat algae, moss, and lichen at the root. After the treatment has had time to work, we carry out patio pressure washing to lift the dead growth and ingrained dirt, then re-sand the joints if needed.
We’d recommend it, particularly if you want to slow down regrowth of moss and algae. Patio cleaning and sealing together protects the surface from weather damage, reduces staining from spills, and generally means you won’t need another deep clean for a longer period. It’s a good option for both home and commercial properties looking to manage maintenance costs over time.
Look for local patio cleaners with verifiable reviews, clear pricing, and proof of insurance. It’s also worth asking whether they’re trained or accredited for biocide application, since this is a controlled treatment. If you’re searching for patio cleaners in my area, checking recent before-and-after photos of similar jobs is one of the best ways to judge the quality of work.
Commercial spaces like pub gardens, restaurant terraces, and office courtyards usually see heavier footfall and need to stay presentable and safe, since algae buildup can make paving slippery. Scheduled visits from a professional patio cleaner are common in these settings, and we work around opening hours to minimise disruption to your business.
Cost depends on the size of the area, the type of surface, and how much buildup needs to be removed. As a general guide, our patio cleaning services are priced per square metre, with combined driveway and patio jobs usually working out cheaper per square metre than booking separately. We provide a fixed quote after a quick site assessment or photos.
Check that the patio cleaning business you choose is insured, uses biocide treatments safely rather than relying on high pressure alone, and has experience with your specific type of paving. A genuinely professional patio cleaner will explain the process to you upfront rather than just turning up with a jet washer.
