External rendering maintenance

External rendering is applied not only for additional curb appeal, but also to protect your building from weather damage and water damage. By applying a thin layer of a cement, sand and lime mix, exterior plastering, or rendering, can provide an additional level of security for your brickwork, as well as little more insulation for your property. However, to maintain these benefits all year round, you should be sure to carry out any external rendering maintenance, before winter really sets in. So, what does this involve? Well, here at Gilston Building Services, we are Southport’s leading building services experts. And this is out guide to everything you should know about taking care of your external rendering.

What does external rendering maintenance involve?

Do make sure your rendering is in tip top condition, you should:

  • Complete a thorough quality check on your existing rendering. Make notes of any hairline cracks, bare patches of brickwork, chips or bulging render. These can all indicate problems for your property, if not rectified as soon as possible.
  • Make any necessary repairs, or call a professional team, depending on the level of damage.

Repairing external render

To repair your external render, you should consult with a professional, for specific guidance about your individual rendering issue. This could include:

  • Exposed brickwork- if your rendering has been damaged by strong winds and bad weather, chunks of the render may be missing, leading to exposed brickwork. This can be repaired by a localised re-render of the area. This will involve removing any hollow, loose and cracked render, to expose bare patches of wall. The wall will need time to dry out before new rendering is applied.
  • Hairline cracks- if you notice any hairline cracks in your rendering, these should be sealed immediately. Failure to act could result in water getting in between the rendering and the brickwork, and then freezing during the winter. The freeze/thaw action will expand the gap, and can case larger cracks or bulging rendering. You can prevent this using a sealant, or by repairing patches of the rendering.
