How do I secure a heavy stone pedestal?

Most heavy stone pedestals and plinths remain stable under their own considerable weight when placed on a level, compacted foundation. Mortar is rarely required unless the piece supports top-heavy statuary in exposed, windy locations. For elevated urns or figures, a concealed stainless steel dowel drilled into the base and pedestal provides additional security against accidental displacement.

Can these garden pedestals stay outside in winter?

Dense natural stones like limestone, sandstone and Purbeck stone tolerate frost well if water is prevented from pooling in un-drained cavities. Placing slate shims beneath the base prevents moisture absorption from wet soil. Cast stone and terracotta require more caution during hard freezes to avoid surface spalling caused by expanding moisture within the porous matrix.

How do I clean moss off old stone?

Light brushing with a soft bristle brush and plain water removes loose debris while preserving the desirable patination accumulated over decades. Aggressive wire brushes and chemical acid washes strip away the aged surface character. Allowing organic growth to remain is standard practice for historic garden ornaments, as it highlights the texture and age of the material.

What is the difference between a plinth and a pedestal?

A plinth generally refers to a lower, simpler block or base that elevates a statue, column or urn from the ground level. Pedestals often possess more architectural definition with distinct capitals, shafts and bases. In garden architecture, these terms frequently overlap depending on the specific classical style and proportion of the piece.
