Our External Rendering Services
We install a full range of render systems to suit every property type, substrate, and budget — from modern silicone finishes to insulated EWI solutions that dramatically improve your home's thermal performance and kerb appeal.
Silicone Render
Flexible, crack-resistant, and water-repellent with a 20+ year lifespan and self-cleaning properties. Available in over 100 colours, silicone render is ideal for modern builds and refurbishment projects across Poole, Bournemouth, and London.
Monocouche Render
A single-coat through-colour system that requires no painting — colour is locked in from day one. Suits brick, blockwork, and concrete substrates with a clean, crisp finish popular in contemporary builds across Dorset and Hampshire.
K Rend & Weber Systems
As approved K Rend and Weber applicators, we install industry-leading premixed render systems in both silicone and mineral formulations. Consistent, high-quality results every time — from Southampton and Guildford to Windsor and Camberley.
External Wall Insulation (EWI) with Render
Add 80–120mm insulation board to your external walls and finish in silicone or mineral render. Dramatically reduces heat loss, improves your EPC rating by 2+ grades, and may be eligible for energy efficiency grants. Popular in Kensington, West London, and Essex.
Pebbledash Removal & Re-Render
Full hack-off of dated or failing pebbledash followed by professional substrate preparation and application of a modern render system. We've transformed hundreds of 1950s–70s homes across Dorset, giving them a completely new exterior.
Render Repair & Renovation
Patch repairs to cracked, hollow, or blown render, full re-rendering of failing sections, and colour-matching to existing finishes where possible. Emergency repairs available across all our service areas including Wiltshire and Hampshire.
Why Choose Kola Construction
Choosing the right rendering contractor is critical. Poorly applied render — whether from inadequate surface preparation, the wrong system for your substrate, or inexperienced operatives — can fail within years, leading to costly remedial work. At Kola Construction, we've spent over 25 years perfecting our approach, working across every render system and building type you'll find in Dorset and London.
We follow BRE guidelines and BS EN 998-1 render standards on every project. We understand why different render systems suit different substrates — why a breathable silicone system is essential on pre-1920s solid masonry, why vapour permeability matters for older homes, and how to correctly calculate U-value improvements when combining EWI with external render. This isn't guesswork — it's technical knowledge built on hundreds of completed installations.

From your initial enquiry to the finished result, we follow a proven four-step process that ensures lasting quality on every external rendering project.
Free Site Survey
We visit your property, assess the substrate, existing render condition, wall type, and exposure zone. We advise on the best system and produce a detailed, itemised quote with no hidden extras.
Surface Preparation
All failing render is removed. Walls are cleaned, cracks and defects repaired, movement joints cut, and bonding agent applied where required. Correct preparation is the single most important factor in render longevity.
Render Application
Scratch coat (or EWI board + base coat if insulating) is applied and allowed to cure. Top coat is then applied in your chosen system and colour by manufacturer-trained operatives. Beads, trims, and reveals are finished to a high standard.
Quality Sign-Off & Guarantee
We inspect the completed work with you, clear the site fully, and issue your 10-year workmanship guarantee. We register the job on our aftercare system so you can call us anytime.
Benefits of External Rendering
Transforms Kerb Appeal
Dramatically improves the appearance and market value of your property — one of the highest-impact exterior upgrades available.
Weatherproofs External Walls
Creates a durable, water-repellent barrier that protects masonry from rain, frost, and wind-driven moisture.
Reduces Heat Loss
EWI-backed render can improve your EPC rating by 2+ grades, cutting heating bills and reducing your carbon footprint.
100+ Colours Available
Choose from over 100 standard colours including custom RAL shades to match your vision perfectly.
Covers Existing Damage
Hides cracked, stained, or failing render and tired masonry — giving your property a completely fresh exterior.
Breathable Formulations
Vapour-permeable silicone and lime renders protect older masonry by allowing moisture to escape — essential for pre-1920s homes.
Low Maintenance
Most silicone renders are self-cleaning — dirt and algae wash away naturally with rainfall, keeping your finish looking fresh for decades.
Crack-Resistant & Flexible
Modern flexible render systems absorb structural movement — ideal for properties with historical settlement or thermal expansion.
Residential & Commercial
We render everything from single-dwelling homes to multi-unit commercial buildings across Dorset, Hampshire, and London.
SuDS-Friendly
Render systems are compatible with sustainable drainage requirements, managing run-off effectively without environmental impact.
Built to Last 20+ Years
Silicone render isn't just about kerb appeal — it's a long-term investment in your property's protection. With a 20+ year lifespan, self-cleaning properties, and exceptional weather resistance, it's the most cost-effective exterior finish available for UK homes.
Our manufacturer-trained operatives use premium K Rend and Weber systems applied to exacting standards, ensuring every project reaches its full design life — backed by our 10-year workmanship guarantee.

What Our Clients Say
"Kola rendered our entire 1970s semi in Bournemouth. The transformation is unbelievable — the house looks brand new. They were tidy, professional, and the finish is flawless. Highly recommend."Sarah T., Bournemouth
"Had our pebbledash removed and silicone render applied in Poole. Brilliant result. The team explained everything at the survey stage, turned up when they said they would, and the price matched the quote exactly."Mark H., Poole
"Used Kola for EWI render on our Victorian terrace in West London. Excellent technical knowledge — they knew exactly which system to use on our old lime-based walls. Already noticed a difference in heating bills."James W., West London
Frequently Asked Questions
Costs typically range from £30–£70 per m² depending on system type, preparation required, and access. A standard 3-bed semi (approximately 120m² of wall area) might cost £4,500–£9,000. Silicone render sits at the higher end of the scale; traditional sand-and-cement at the lower. We provide free, itemised, no-obligation quotes after a site visit so you know exactly what you're paying for.
Modern silicone and monocouche renders last 20–30 years when correctly applied and maintained. Sand-and-cement renders typically last 15–20 years. EWI systems have a 30+ year design life. Longevity depends on substrate preparation, mix quality, and exposure level — which is exactly why we invest so heavily in getting the preparation stage right.
Sometimes yes, but only if the existing render is fully sound — no cracking, hollow sections, or movement. We always test by tapping the existing surface with a hammer to check for delamination. If there's any doubt, we recommend full hack-off for a lasting result. Rendering over failed render is one of the most common causes of early failure in the industry.
For Victorian, Edwardian, and pre-1920s homes, breathable lime or silicone renders are essential. Traditional solid masonry walls need to breathe — trapping moisture behind an impermeable render leads to damp problems and structural damage over time. We advise on the correct system for every building type during the free survey, taking into account wall construction, exposure zone, and existing finishes.
In most cases, no — external rendering falls under permitted development rights. Exceptions include listed buildings, properties in conservation areas, or situations where the render would change the character of the building significantly. We advise on planning status as part of every survey and can assist with applications where required.
A typical 3-bed semi takes 3–5 days from start to finish, including preparation and curing time between coats. Larger properties or those requiring EWI installation may take 7–14 days. We work efficiently and cleanly to minimise disruption, and we'll give you an accurate timeline at the quotation stage.

Understanding Render Systems
Not all renders are created equal — and choosing the wrong system for your property can lead to cracking, moisture trapping, and premature failure. At Kola Construction, our team's in-depth technical knowledge ensures the right render is specified for every project.
Silicone Renders
The most popular choice for UK external rendering. Highly flexible, water-repellent, and vapour-permeable — they shed rain while allowing trapped moisture to escape. This breathability is critical for older masonry homes across Dorset, Hampshire, and London. Silicone renders also resist algae and dirt build-up thanks to hydrophobic surface properties, effectively making them self-cleaning.
Acrylic Renders
Harder-wearing with excellent impact resistance, making them suitable for high-traffic or commercial areas. However, they're less breathable than silicone, so they're generally recommended for newer cavity-wall properties rather than Victorian or Edwardian solid-wall homes.
Mineral Renders
Cement-based with exceptional breathability — the most permeable of all modern renders. Ideal for heritage properties and lime-based substrates. However, they require separate painting, which adds a maintenance step that silicone and through-colour monocouche systems avoid.
EWI & U-Value Improvements
External Wall Insulation (EWI) combined with a render finish is one of the most effective ways to reduce heat loss through solid walls. By adding 80–120mm of insulation board to your external walls, you can improve your wall's U-value from a typical uninsulated 2.0 W/m²K down to 0.30 W/m²K or better — meeting and exceeding current Building Regulations. For homeowners in London, Wandsworth, Putney, or Essex, this translates to a significant EPC improvement and meaningful savings on annual heating bills.
What to Look for in a Rendering Contractor
When choosing a rendering contractor, look for manufacturer accreditation, independent verification, clear evidence of completed work in your local area, and a written workmanship guarantee. Be cautious of contractors who don't carry out a site survey before quoting, who can't explain which system they'll use and why, or who offer prices significantly below the market average — cutting corners on render preparation is the leading cause of early render failure.
