5 Signs your patio needs a professional clean

Your patio is meant to be a relaxing, attractive outdoor space, however, over time, exposure to the elements can leave it looking tired or even unsafe. Not sure if it’s time to call in a professional? Here are five clear signs your patio needs a deep, expert clean:

1. Slippery surfaces

If your patio becomes dangerously slippery after rain, it's likely due to a buildup of algae, moss, or grime. A professional clean will remove this safely, reducing the risk of slips and falls.

2. Black spots or stains

Black spots (often lichen) are stubborn and won’t budge with basic scrubbing or DIY pressure washers. These require specialist treatments and techniques to fully remove without damaging the stone.

3. Dull or faded appearance

Has your patio lost its original colour and vibrancy? Dirt, pollution, and organic growth can cause surfaces to look dull. A professional clean can bring back the original finish, making your patio look fresh again.

4. Weeds growing between cracks

Weeds or moss growing between paving joints can loosen the structure and cause long-term damage. A proper clean removes both the visible growth and root systems, helping to prevent regrowth.

5. You’re preparing to sell or host

If you're planning a garden party or putting your home on the market, a professionally cleaned patio makes a great impression and instantly boosts curb appeal.
