Local considerations in Portishead
Surveys in Portishead also cover the surrounding BS20 district and towns such as Nailsea and Clevedon. Portishead is about 19 miles from Bath. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Somerset: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
Extensions and new blockwork in Portishead are where monocouche makes most sense.

Planning and building control in England
Before quoting in Portishead, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Portishead: questions
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
Does monocouche need painting?
No — it's through-coloured. Cleaning every few years keeps it looking fresh.
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
