Our specialist services for timber frame buildings include:
We work with homeowners, architects, conservation specialists and building contractors throughout Worcestershire, Gloucestershire, Herefordshire, Warwickshire, Shropshire, the West Midlands and surrounding counties.
Whether you own a centuries-old black and white cottage, a listed farmhouse or a modern timber frame home, choosing the right insulation system is essential. Traditional timber frame buildings need breathable materials that allow moisture to escape naturally while improving energy efficiency and protecting the structure beneath.
We specialise in breathable External Wall Insulation (EWI), insulated lime render systems and traditional lime solutions for timber frame buildings throughout Worcestershire. Every system we install is designed around the way your property has been built, helping to improve thermal performance while preserving the long-term health of the timber frame.
From Worcester and Malvern to Bromsgrove, Redditch, Kidderminster, Droitwich Spa, Pershore and Evesham, we help homeowners make their properties warmer, more energy efficient and better protected using carefully specified breathable wall systems.




Worcestershire has a rich history of timber-framed buildings, from rural farmhouses and traditional black and white cottages to listed homes and converted barns. Many of these properties were built hundreds of years ago using natural materials such as oak, lime mortar and lime render, allowing moisture to move freely through the walls.
Unlike modern cavity wall construction, timber frame buildings rely on breathable materials to remain healthy. If moisture becomes trapped behind impermeable render or unsuitable insulation, it can lead to condensation, mould, timber decay and expensive structural repairs over time.
That's why every timber frame property should be assessed individually before insulation or rendering work begins. We carefully consider how the building has been constructed, the existing wall finishes, previous alterations and moisture movement before recommending the most suitable breathable solution.
By combining vapour-permeable insulation with compatible lime render systems, we help homeowners across Worcestershire improve energy efficiency while allowing their property to perform as it was originally intended.


Traditional timber frame buildings lose a significant amount of heat through their external walls. Breathable External Wall Insulation provides a practical solution by improving thermal performance without trapping moisture inside the building.
Unlike internal insulation, External Wall Insulation creates a continuous insulated layer around the outside of the property. This reduces thermal bridging, improves internal comfort and retains the original room sizes inside the home.
Because we use breathable insulation systems specifically designed for traditional construction, moisture vapour can continue to move naturally through the wall while the property benefits from modern levels of insulation.
Choosing the correct finish is just as important as selecting the right insulation system. Many of Worcestershire's timber frame buildings were originally constructed using breathable materials that allow moisture to move naturally through the walls. Using the wrong render can prevent this process, potentially leading to damp, condensation and long-term damage.
For many traditional timber frame buildings, a breathable lime render is often the most appropriate solution. It works with the building rather than restricting it, helping protect both the timber structure and the overall performance of the wall.
Worcestershire has a diverse mix of traditional timber-framed properties, each with its own construction methods and maintenance requirements. From historic cottages tucked away in rural villages to substantial farmhouses and converted barns, many of these buildings were designed to breathe naturally.
You'll find timber frame properties throughout the county, particularly around Worcester, Malvern, Tenbury Wells, Pershore, Bewdley, Droitwich Spa and the surrounding countryside. Many have stood for hundreds of years because they were built using breathable materials that allow moisture to move freely through the structure.
Unfortunately, we often see older properties that have been repaired using modern, impermeable products. While these repairs may have been well intentioned, they can sometimes create problems by trapping moisture within the walls.
Every building is different, which is why we begin with a detailed assessment before recommending any insulation or rendering system. Our aim is always to preserve the original construction while improving comfort, energy efficiency and long-term performance.
One of our recent timber frame restoration projects was completed in Colwall, just outside Malvern on the Worcestershire and Herefordshire border. This traditional timber-framed property had previously been repaired using cement-based render and metal mesh, which had deteriorated over time and was preventing the walls from breathing properly.
Following a detailed assessment, we removed the unsuitable materials and designed a fully breathable wall system that respected the original construction of the building while significantly improving its thermal performance.
The existing cement-based render had begun to fail and was restricting the wall's natural ability to regulate moisture. This is a common issue we encounter on traditional timber frame buildings where modern materials have been introduced during previous repairs.
After carefully removing the unsuitable render and metal mesh, we installed loose wood fibre insulation within the wall cavities before constructing new timber studwork to support wood wool carrier boards.
The walls were then prepared using a traditional lime putty scratch coat reinforced with natural hair, creating a breathable foundation for the final lime render system.
This approach allows moisture vapour to move naturally through the wall construction while improving insulation, helping to create a warmer, healthier and more energy-efficient home without compromising the integrity of the original timber frame.
Although this project was completed in Colwall, it perfectly demonstrates the specialist breathable timber frame systems we install for homeowners throughout Worcestershire, including Worcester, Malvern, Bromsgrove, Redditch, Kidderminster, Droitwich Spa, Pershore and Evesham.
We provide timber frame external wall insulation throughout Worcestershire, including both towns and surrounding rural communities.

Not normally one for doing reviews but Steve managed to squeeze my job in so I could make use of the green homes scheme before it closed and the job they did is spot on. From start to finish, very pleased from the office to the guys carrying out the work.
WP Rendering have just completed a beautiful job on the rear of our new farm house. The work has been done to a very high standard by a qualified hard working team, leaving the site clean and tidy, I can not recommend them highly enough. A very satisfactory job.
Thanks for everything guys! we are so pleased. communication was great, and the finished piece was even better than we expected! would highly recommend this this company! Thanks Steve.
This is the second time my family have used this company now and they’ve never let us down! Excellent service! Great communication! I couldn’t recommend them enough.
Very pleased with the insulated render, our home is now warmer and looks great from the outside.
Steve’s team of three led by Simon have a work ethic second to none, they are very hard-working, polite and cleared up every day. The project was completed quickly, only being constrained by the short daylight hours and occasional rain in January. By its nature the work is messy at times but the house and surrounding ground were well covered and left clean and tidy when the work was finished.
Excellent job done of rendering top half of house with thermal no maintenance render. The team that carried out the work cannot be faulted, very hard working, answered any queries and cleared paths etc when they went home every day. As with any building work, expect a little mess but it was kept to a minimum. The only downside is that having the work done in the wetter months causes delays – absolutely no fault of WP Rendering.
Thanks so much for doing an amazing job of the render of our house, it’s made a huge difference we couldn’t be happier. Great team of guys working on it & they did a great job protecting our patio & left the place immaculate. Would highly recommend.
The whole job ran smoothly from start to finish possibly due to the influence of the boss Steve. I would and have recommended WP to anyone I know looking for a rendering job, the 4 guys were polite, professional and I couldn’t fault their work ethic. The finished product I can’t fault and when the team left site they left everything clean and tidy. The team Carlos,Pedro,Nelson and Antonio couldn’t do enough to help and they battled on through all weathers.
Excellent, fast friendly service. Great job with a professional tidy team! Went above and beyond including doing small jobs that weren’t anything to do with them! Really could not get a better company! Would recommend to anyone!
