Advantages of Wall Rendering:

  • Visually Pleasing

Adding a render coat to your property will instantly brighten up shabby looking walls and give them a sleek uniform finish. The fresh coat will not only appeal to passersby but to everyone who visits your property.

  • Protective and Weather Resistant

Exterior walls are subject to a lot of wear and tear as they are exposed to the harsh elements. Rendering will provide the walls with much-needed protection from scorching summers to severely cold winters. The coat also prevents leakage or seepage, keeping buildings free from damp issues year-round.

  • Seamlessly Blends Buildings

Rendering is also used to create a unified look between buildings or between areas of one building. If your property was built decades ago and you recently upgraded it with an extension, rendering will tie the old building with the new one beautifully.

Types of Renders We Offer:

  • Traditional sand and cement
  • Silicone
  • Acrylic Thin Coat
  • Monocouche
  • External Wall Insulation
  • Lime Based Renders

Good design and workmanship are primary factors when achieving a waterproof construction. We will consider the feasibility of both the project and other proposed building works. The surveyors will be able to discuss your proposals in detail, offering advice on the likely size and practicality of the design and in some cases will identify any particular design/planning issues.

“The front of our house now looks amazing!”

“We are very pleased with the work TCA rendering carried out on our house. After initial hiccups with the vents not arriving on time, things were quickly rescheduled for the following day. The guys then worked hard, both inside and outside the house, depending on the good old English weather!! From start to finish we were kept informed of progress. They were polite, chatty and clearly very good at their job, as the front of our house now looks amazing! Impressed also with how quickly the site was cleared too – the scaffolding and the rubbish went the day they finished! Thanks.”

“I wouldn’t hesitate to recommend TCA rendering”

“All work was carried out as agreed in the estimate. It was done to a very high standard and the finish was first class. They were very hard working and put in long days. They left the site clean, tidy and safe. When the job was finished we were walked around the house and shown through everything. I wouldn’t hesitate to recommend TCA rendering & insulation”

“Thoroughly recommend this company”

“The work was finished to a high standard and the house was put back together efficiently and quickly. The team worked particularly hard on the clearing up and cleaning, and were pleasant and polite throughout. I would thoroughly recommend this company.”

“An excellent job was done”

“The guys did a fantastic job and continued to work through some really cold and wet days, the job took longer than anticipated due to hold-ups with the weather but the finished work is outstanding. They had started the rendering when asked if they could also do guttering, this was not part of the original quote but the quote was reasonable and again an excellent job was done. I would have no hesitation in recommending TCA Rendering and Insulation”
