External Wall Insulation

Internal Wall Insulation

Roofing Insulation

Our products create a beautiful and durable finish to your walls in a range of modern and traditional colours. They also provide thermal insulation to reduce your heating bills, resist cracking and discolouration and they weather-proof your building while still allowing it to breathe. They are a low maintenance solution with a long lifespan. Our long-lasting, natural exterior wall coatings don’t fade, crack, chip or peel, they are breathable, flexible, weather-resistant and insulating.

Our natural insulation product is breathable and has great thermal properties so can be used internally to solve issues with damp and mould. This can then be over skimmed plastered and painted giving you the freedom to decorate over it as you please. . The Final coating is only 8mm thick so no need to worry about replacing fixtures and sockets etc. reduces cold wall and condensation . 25 year product warranty available . Reduction in Heat loss of 30%

Do you struggle to control the temperature of your conservatory, making it unusable for most of the year? There is a solution which doesn’t involve the expense of replacing the roof, but will help to make your conservatory an enjoyable area to relax in. Very few conservatories offer a comfortable year-round solution – they are either too hot in summer, or like a fridge in winter. And if it’s raining, the noise can make the conservatory too noisy to enjoy relaxing in.

“Painting exterior of house…”


“Gary and the team where fantastic. Professional, clean, tidy and nothing was too much trouble. The attention to detail for the works carried out was exceptional. Even when a few extra bits were added they were very accommodating and even making suggestions that were excellent but added to their workload. I would recommend Universal Painters without hesitation. Excellent workmanship and very professional..”

~ Bruce

“Practical, helpful approach…”


“This isn’t the first time Gary has completed work for us so we knew what to expect before he arrived. He’s always been extremely helpful and knowledgable, quick to respond and, as we’ve had work done by him before, we know it works. Gary has been able to advise exactly what needs doing and has made it work within four budget. He also always provides advice for the trades completely the next stages – plastering, decorating etc. Highly recommend Gary for damp proofing services.

~ Jane

“Practical, helpful approach…”


“The boss Gary was very friendly and knowledgable and provided us with a very competitive quotation in writing and within 24 hours of his on site survey. We found his team to be very hard working but they made time to explain the processes and keep us informed. The complete job looks great and comes with a 20 year warranty. No money was requested up front and we were happy to pay in full (via bank transfer) as soon as the job was completed. Top marks, they are a great little company.”

Universal Painters serves customers throughout all of the London, Oxfordshire, Buckinghamshire and Hertfordshire. Originally based near Ruislip. We also cover all of the Home-Counties. 

Internal wall insulation can be done by fitting rigid insulation boards to the wall. We use natural cork which means you only lose 6mm of internal space.

External wall insulation involves a layer of insulation material being attached to the wall on the outside of the home, which is then covered with a special type of plasterwork or cladding which can then be decorated over.

All of our services are fully project managed, insured, guaranteed (subject to terms and conditions), and are carried out by friendly, helpful, and qualified painters and sprayers. All of our services are provided with customer satisfaction guaranteed.


Universal Painters are proud City & Guilds painters and sprayers and also members of Trustpilot. Any of our reviews and testimonials can be verified upon request and all of our work is carried out to the highest standards.
