Approved contractors for K Rend, Parex, Ecorend, VPI and DecoRend
Leeds Render Systems are approved contractors for render systems from Ecorend, K Rend, VPI, DecoRend and Parex. We fit them on homes and commercial buildings across Leeds and beyond.
The systems we install
Which system suits a wall depends on the background, the finish you want and the manufacturer's requirements. We go through the options at the site visit.

Ecorend
Ecorend is a UK render manufacturer based in Dalton, North Yorkshire, and part of the Wetherby group. It makes through-coloured (monocouche) and thin-coat render systems in Yorkshire.
Ecorend systems we install
As approved contractors, we can install render systems from the Ecorend range, including:
- MR1 One Coat Render: a through-coloured monocouche render that Ecorend describes as low-carbon
- LMR1 Lime Monocouche: a one-coat lime render for traditional solid masonry and older buildings
- SR15 Silicone, SF15 Sil-Flex and SR365 Ultimate Silicone: silicone thin-coat renders
- DR1 Dash Receiver: a base for dry-dash finishes
- EWI versions of its systems: for external wall insulation
We confirm the exact system for your walls at the site visit and in your quote.
Suitable for
New and existing masonry homes and commercial buildings. Ecorend positions the lime system for heritage and solid-wall properties that need to breathe, and its insulation systems for improving energy efficiency.
Finishes
Through-coloured renders give an even colour and texture with no painting. Thin-coat systems come in a range of colours and textures; Ecorend offers a colour selector.
Main benefits
Ecorend states its products carry British Board of Agrément (BBA) approval, and that through-coloured finishes remove the need for repainting.
Maintenance
Through-coloured renders carry their colour right through, so they do not need painting. Keep gutters, downpipes and window sealant in good order so water does not run down or behind the render. Silicone finishes are made to shed water, but shaded or north-facing walls can still pick up dirt or green algae over time. A suitable render cleaner applied gently is usually enough; avoid a pressure washer held close to the surface. For a specific product, follow the manufacturer's own care guidance; we can tell you which applies to your walls.
