Natural stone for hard-working outside walls

Exterior stone cladding can change a plain wall, frontage or boundary into something with weight, texture and a proper finished look. Choosing Deerpark Stone means the outside work is planned around the realities of the wall, including preparation, setting out, corners, openings, edges and the choice between dry-stack and jointed styles. We also look at the proportions of the wall and the materials around it, because the same stone can read very differently beside render, brick, timber or darker frames.

Weather-aware fitting and waterproof joint options

Jointed exterior finishes need more than a tidy line. A Deerpark Stone installation can use a special jointing mix on specified jointed Glenmore Limestone, Creggaun Sandstone and Kilkenny Limestone finishes to create a long-lasting waterproof seal. We also plan work around the weather and protect the stone while it cures, which matters far more outside than it does on a sheltered indoor wall. Once finished, the surface is straightforward to look after and keeps the character of real stone.

Frequently asked questions

Is natural stone cladding suitable for exposed exterior walls?

Yes, provided the wall is suitable and the installation is planned correctly. Exterior work needs careful preparation, sound fixing, proper corner planning and sensible curing conditions, because outside walls have to deal with weather as well as the finished look.

Which jointed finishes can use the waterproof joint mix?

The special jointing mix is used on specified jointed Glenmore Limestone, Creggaun Sandstone and Kilkenny Limestone finishes. It is there to create a long-lasting waterproof seal where that type of jointed exterior finish has been chosen.

How do I look after exterior stone cladding once fitted?

Day-to-day care is fairly straightforward. The main thing is getting the installation, jointing and curing right in the first place. Once the work is complete, the stone keeps its natural character without needing fussy treatment to look like stone should look.
