Seaham: walls, weather and approvals
We cover Seaham and nearby Houghton-le-Spring, Sunderland and Peterlee. It's roughly 23 miles from Seaham to Darlington, the largest town in County Durham. The North East has many solid brick terraces, including former colliery housing, plus post-war council estates with some system-built homes.
Exposure to wind-driven rain varies across County Durham: 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.
We plan monocouche in Seaham for settled weather so each elevation can be finished in one go.

Approvals in England
Before quoting in Seaham, 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.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
Can monocouche go over insulation?
No — insulation systems use a mesh-reinforced base coat and a thin-coat finish instead. If you want insulation as well as a new finish, see insulated render.

Monocouche render in Seaham: questions
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.
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
