Benefits of a flagstone patio

Flagstones are a great choice for patios of all types and sizes. Allowing you to create a really natural look, these paving slabs are incredibly durable and can be laid dry for a permeable surface.

You can allow moss and grass to grow between the flagstone if you’re after a natural look, or you can keep things sleek and clean with cement or pebbles between the flags.

Flagstones are also incredibly versatile. They are available in a range of stones and colours to suit the look you want and can be laid in countless different layouts and designs.

Choosing a colour, style and pattern

There are plenty of styles and colours of flagstones available, so you’re sure to find ones that suit the style of patio you’ve got planned.When it comes to layouts and patterns, there’s just as much choice! From basic to creative, simple to more complex, there is a huge range of designs to choose from.

Patterns include motifs, single size patterns, herringbone patterns, multi-size patterns and random layouts. Pinterest is a great place to find inspiration!

Flagstone patio ideas for gardens

Preparing the ground for installation

Before a flagstone patio can be laid, the ground will be prepared to ensure it is level.

Firstly, you’ll need to mark the patio edges, using stakes and string.

All grass and plants will need to be removed from the area. You’ll then need to dig down far enough to accommodate the paving slabs, as well as the levelling material and a gravel base, if one is being used.

As a general rule, you’ll need to dig down six inches, plus the depth of the flagstones you’re using.

Aftercare of a flagstone patio

Once your flagstone patio has been installed, it’s important that you carry out the correct maintenance to ensure it stays looking its best for years to come.


You should brush your flagstone patio thoroughly three to four times a year. Use a stiff brush to clean the patio with hot, soapy water. You should also ensure that you remove any dirt frequently, and don’t let it sit on the stones for too long.

Removing stains

If you find that your flagstones become stained, try removing them initially with a power washer. If this doesn’t work, you can also buy specialist cleaning products, but remember to test on a small area first to ensure they won’t damage the stone.


Some people seal their flagstone paving. This can help to make cleaning easier, can enhance the colour or create a glossy, stylish finish. If you do decide to seal your flagstones, it’s important to find the correct sealant and follow the manufacturer’s directions.

Of course, the best way to create a beautiful and lasting flagstone patio in your garden is to get it professionally designed and laid.
