External wall insulation in Rainham, insulation and render in one system on solid walls. Warmer inside, modern finish outside. Free survey and fixed quote.
Insulation board fixed and rendered over as one system, not render with something behind it.
Sills, eaves, reveals and downpipes all move outward. Getting those right separates a good EWI job from a bad one.
Most people notice the noise as much as the heat, which near the A13 is worth having.
The render is part of the system, so the frontage is modernised as well as insulated.
Where only one half of a semi is insulated, the edge at the party line is detailed neatly so both houses look finished.

The interwar housing around Rainham was built with solid walls and no insulation, so the heating goes straight back out through them. External wall insulation fixes that from outside and gives a new rendered finish at the same time, two jobs, one scaffold.
On Rainham interwar semis the details decide whether external insulation looks right: the window sills have to be extended, the roof overhang checked, and pipes, meters and satellite dishes moved outwards. On a semi-detached house the join with the neighbour is planned too, because only one half may be insulated.
On an uninsulated solid wall, a large one. Those walls lose heat faster than anything else in the house, and EWI is the only fix that does not cost you room size inside.
Around 100mm, so sills, eaves and downpipes need extending. That detailing is most of the skill, and a cheap quote usually means it is being skipped.
Yes, and on a semi it often should be: the exposed gable makes the biggest difference. We will tell you which wall is actually costing you money.
The insulation stops at the party wall line, and the edge is finished with a trim or a return so it looks deliberate. It is worth talking to the neighbour first, and a party wall notice may be needed for some work near the boundary.
Not usually, but the sills are extended to project past the new, thicker wall. If the windows are due for replacement anyway, doing that first lets them be set further out in line with the insulation.
Not when it is designed properly. Insulating the outside keeps the wall itself warm, which usually reduces cold spots and mould inside. The details around the windows and at the base of the wall are what matter, and they are planned before any boards go on.
