External Wall Insulation — what you need to know
External wall insulation (EWI) adds a continuous layer of insulation to the outside of a property, then applies a render or coating finish over it. This transforms the thermal performance of the building without disrupting the interior — no loss of internal floor area, no need to vacate rooms. EWI is particularly effective on solid-walled properties (Victorian and Edwardian housing built before 1920), which cannot be cavity-fill insulated and where solid walls lose heat far more quickly than modern cavity-wall construction. EWI systems are available with silicone render, monocouche or protective coating finishes.
Solid-walled interwar mining estate properties in Edlington rely on external render for weather protection — silicone render re-renders are chosen for long-term durability on properties where homeowners invest in improving energy efficiency and weatherproofing.

Properties where cavity wall insulation is not possible due to construction type or cavity condition
Homes where the external render is failing and the two projects — insulation and re-render — make sense to combine
Interwar solid-brick or rendered properties where original cavity attempts were partial and insulation standards were not met
Property considerations in Edlington
Edlington is a former mining village south-west of Doncaster, associated with the former Yorkshire Main Colliery. The housing stock includes interwar mining estate housing — semi-detached and terrace properties built in the 1920s and 1930s for the colliery workforce — and post-war development. Many interwar properties are of solid masonry construction. The village is close to Mexborough and Conisbrough in the Don valley.
Edlington's south-west Doncaster position means standard South Yorkshire rainfall — interwar solid-walled properties in the area benefit from maintained external render.

Our approach
Survey and specification
We survey the property, measure the wall area, assess the substrate and identify any preparation needed (masonry repairs, making good before fixing boards). We specify the correct insulation thickness and render finish for the property's requirements and budget.
Preparation and substrate work
The wall is cleaned and any defective existing render or masonry is repaired. Window and door reveals are extended where required. Special attention is paid to reveals, sills, eaves details and the base of the wall where the insulation terminates.
Insulation board fixing
Insulation boards (EPS, mineral wool or phenolic, depending on specification) are mechanically fixed and adhesive-bonded to the wall in a staggered pattern. This creates a continuous, uninterrupted insulation layer with no cold bridges.
Base coat and mesh
A polymer-modified base coat is applied over the boards, and fibre mesh is embedded into the wet render. This base coat holds the system together and provides the reinforcing layer that distributes movement stresses.
Finish coat
The specified finish — silicone render, monocouche or protective coating — is applied to the cured base coat. The wall is now insulated, weatherproofed and given a fresh external appearance.
What determines the cost
We provide fixed written quotes — what you are quoted is what you pay. The factors below determine where your project sits within the range for this type of work.
- Total wall area to be insulated
- Insulation board type and thickness — thicker or higher-performance boards cost more but improve thermal performance
- Render finish specified — silicone, monocouche and protective coating vary in cost
- Substrate preparation — significant masonry repairs or removal of existing render adds cost
- Reveal extensions and window cill replacements required when boards increase the wall thickness
The most accurate way to understand the cost for your specific property is a free on-site survey. We assess the substrate, take measurements and provide a full itemised written quote.

Common questions
Does EWI change the appearance of the property?
Yes — EWI adds to the external face of the wall, which changes the profile of window and door reveals and the overall external appearance. In practice, properties look freshly rendered after EWI, which most homeowners consider an improvement. Reveals are extended using appropriate profiles and the finish is consistent across the elevation. We bring colour and finish samples to the survey to help you choose.
Are there grants available for EWI?
Government schemes — including the Great British Insulation Scheme and the Energy Company Obligation — may fund or part-fund EWI for qualifying households. Eligibility depends on property type, current insulation level and other factors. We can advise on what may be available and signpost to the relevant scheme administrators, though we do not administer grants directly.
Will EWI affect neighbours on a terrace?
On a mid-terrace or end-terrace property, EWI is typically applied to the front and rear elevations only, with party walls left. On end-terrace properties, the exposed gable can also be insulated, which often provides significant heat loss benefit. We advise on which elevations are practical and cost-effective during the survey.
