External wall insulation in Elm Park, insulation and render in one system on solid walls. Warmer inside, modern finish outside. Free survey and fixed quote.
The 1930s Elm Park houses were built with solid walls and no insulation, which is why they are expensive to heat and why the heating comes straight back out. External wall insulation fixes that from the outside and gives you a new rendered finish at the same time, so it is two jobs for one scaffold.
On the Elm Park estate plenty of semis have already had one side insulated by a neighbour, so the job is often matching an existing finish and thickness at the party line. Window sills, downpipes and meter boxes all move out with the new wall line, and they are planned before the scaffold goes up.
On an uninsulated solid wall, a large one. Those 1930s Elm Park walls lose heat faster than anything else in the house, and EWI is the only way to fix that without losing room size inside.
Around 100mm typically, so sills, eaves and downpipes all need extending. That detailing is most of the skill and most of the reason a cheap quote is a warning rather than a bargain.
Yes, and on a semi it often is: the exposed gable makes the biggest difference. We will tell you which wall is actually costing you money rather than insulating all of them by default.
Often not, because external wall insulation on a house can fall under permitted development when the finish is similar to what is there. Rules vary, so it is worth checking with Havering planning before the work is booked.
Typically two to three weeks on a semi, depending on the weather and how many elevations are done. Boards and render cannot go on in heavy rain or frost, so the programme allows for British weather.
Insulation board fixed and rendered over as one system. It is not render with something behind it.
Sills, eaves, door reveals and downpipes all move outward. Getting those right is what separates a good EWI job from a bad one.
Most people notice the noise as much as the heat. A solid wall with EWI is a different house in January.
The render is part of the system, so you get the modern frontage as well as the insulation.
Meter boxes, downpipes and satellite dishes repositioned onto the new surface. Moving a gas meter itself is arranged with the gas supplier.
Window sills lengthened so rain drips clear of the new, thicker wall instead of running down its face.
