Thank you I also need to give a shout out to Sam, the surveyor who came to talk to us about what we wanted and what we needed.

I couldn’t be happier with the damp proof course and weather treatment work carried out on my house. Ricky and his team were absolutely amazing from start to finish. The work took place over a few days and throughout the whole process they were polite, professional, and incredibly respectful of me, my property, and even my dog, who completely fell in love with Ricky. At the end of each day they took the time to show me the work they had done, made sure I was happy, and patiently answered all of my many questions. It was an absolute pleasure dealing with them.

What is an Energy Efficient Wall Coating?
An energy-efficient wall coating is a specially formulated exterior or interior paint that helps regulate your home’s temperature. At Home Energy Save GB, we use advanced coatings with thermal insulation properties that reflect heat in summer and retain warmth in winter.
This reduces your reliance on heating and cooling systems, lowering energy bills and increasing comfort year-round. Ideal for homeowners and landlords looking to improve energy performance, these coatings also protect walls from weather damage and damp. It’s a smart, cost-effective upgrade that enhances property value while cutting carbon emissions.
What is the Energy Efficient Wall Coating Application Process?
Pre-Wash
Power-washing eliminates algae, moss and lichens. This also exposes any flaws in the surface, which are then repaired.
Biocide Treatment
After any necessary repairs, the wall is sterilised with a biocide treatment, which ensures no regrowth of any living organisms can grow through the coating.
Microporous Wall Coating
Application of microporous coating, which gives a waterproof surface but allows the wall to breathe.
Post-Treatment/Drying
One hour after application, the wall is drying. Allowing two days to dry, the external walls masonry will return to their natural appearance following the process.
Signs You Need an Energy Efficient Wall Coating
Cold or Draughty Rooms
If your home feels chilly even with the heating on, your walls could be losing valuable warmth.
Rising Energy Bills
Higher heating costs often point to poor wall insulation and unnecessary heat loss.
Damp, Mould, or Mildew
Moisture on internal walls is a sign that water is penetrating through your exterior surfaces.
Peeling Paint or Cracked Render
Visible damage to exterior walls allows weather in—and heat out.
Discoloured or Stained Walls
Green staining, algae, or water marks suggest your walls are absorbing rather than repelling moisture.
Old or Untreated Exterior Walls
If your property hasn’t had exterior maintenance in years, it’s likely underperforming in energy retention.

Free Damp Survey with Home Energy Save GB
Protect your home from costly damp problems with our free, no-obligation survey. At Home Energy Save GB, we assess for signs of moisture, heat loss and damage to external walls. These are common causes of rising energy bills and uncomfortable living conditions.
Our experts will check if your property is suitable for an energy efficient wall coating, which creates a breathable and waterproof barrier that helps prevent damp while improving insulation. Avoid future repair costs and reduce heat loss by booking your free damp survey today.
How Does an Energy Efficient Wall Coating Work?
An energy efficient wall coating works by forming a protective, breathable layer on your property’s exterior walls. This advanced coating repels rainwater while still allowing trapped moisture inside the walls to escape. By keeping the walls dry, it improves their ability to retain heat, which helps reduce heat loss and makes your home warmer and more comfortable.
The coating also protects against damage from the weather, such as cracking, staining and damp penetration. Over time, this helps lower your energy bills, reduces maintenance costs and extends the life of your exterior walls while improving the overall appearance of your home.

Frequently Asked Questions
Are energy efficient wall coatings suitable for all types of homes?
Energy efficient wall coatings are suitable for most types of residential properties, including brick, stone and rendered homes. However, suitability can depend on the current condition of your walls, the level of existing insulation and any previous treatments applied. That is why we always recommend a professional survey first to assess whether your property will benefit. Homes with solid walls or those experiencing damp, flaking paint or heat loss are usually excellent candidates. If your property is a listed building or in a conservation area, additional permissions may be needed before work can begin.
Will an energy efficient wall coating stop damp and mould?
Yes, an energy efficient wall coating is highly effective in preventing external damp from penetrating your walls. By creating a waterproof yet breathable layer, it stops rainwater from being absorbed into the wall surface. At the same time, it allows internal moisture to escape, which helps prevent condensation build-up that can lead to mould and mildew. While the coating does not fix internal plumbing leaks or rising damp, it significantly reduces the risk of penetrating damp caused by driving rain.
How is the energy efficient wall coating applied?
The coating is typically applied using specialist spray equipment by trained technicians. The process starts with a full property survey, followed by surface preparation which includes cleaning, repairing cracks, and applying a primer if needed. Protective masking is used to shield windows, doors and any surrounding areas. Once the surface is ready, the coating is sprayed on in even layers to ensure a consistent, professional finish. The product then cures and bonds to the wall, forming a strong, long-lasting barrier. The entire process is usually completed in one to two days depending on the size and condition of the property.
Does it affect the appearance of my home?
Yes, and in a positive way. Energy efficient wall coatings not only improve performance but also enhance the visual appearance of your property. They offer a clean, smooth and consistent finish that covers up stains, cracks and flaking paint. Coatings are available in a range of colours and textures to suit your preferences and property style. The result is a freshly restored exterior that looks smart and well maintained. Many homeowners report that the coating gives their property a more modern, well-kept appearance, which can even increase kerb appeal and overall property value.
Will energy efficient wall coating reduce my heating bills?
Yes, energy efficient wall coating helps reduce heating bills by improving your home’s ability to retain heat. The coating forms a waterproof barrier that prevents moisture from entering the walls, which otherwise causes heat loss. Dry walls hold warmth better, so your heating system works less to maintain a comfortable temperature. Over time, this can lead to noticeable savings on energy costs. The coating also helps reduce drafts and cold spots, making your home warmer and more comfortable throughout the year.
Can energy efficient wall coatings be applied to older properties?
Yes, energy efficient wall coating is suitable for many older properties, particularly those with solid walls that lack modern insulation. It helps protect fragile or weathered surfaces and improves thermal performance by preventing heat loss. Before application, a professional survey is essential to check wall condition and address any repairs needed. This service can extend the lifespan of older walls and improve comfort without altering the character of your home. It’s a popular choice for those wanting to improve energy efficiency while preserving period features.
How do I know if my home needs energy efficient wall coating?
You may need energy efficient wall coating if your home shows signs of damp, peeling paint, cold or draughty rooms, or rising energy bills. A professional survey is the best way to confirm this. Surveyors will inspect your external walls for damage, moisture ingress and insulation issues. If the walls are porous or suffering from wear, the coating can provide protection and improve thermal performance. Booking a free survey can help you understand if this solution is right for your property and what benefits you can expect.
