What is the average lifespan of pebble dashing?
Pebble dashing is a popular exterior wall surface treatment that has been used to decorate the outside of homes for centuries. It is created by mixing a cement base with gravel or small stones (known as “pebbles” or “dash”) and then forcibly throwing the mixture onto the surface of the wall. The result is a captivating, natural look that is both visually appealing and highly weather resistant.
When homeowners are considering a pebble dash finish for their walls, one of the questions they may have is how long it will last. How long is the average lifespan of pebble dashing?
The answer depends on a mix of factors. The quality of the material used for the pebble dash along with the skill of the tradespeople and the weather conditions all play a vital role in determining the durability and longevity of the finish. Similarly, how well the dashing process was executed and how often it is maintained will also affect its lifespan. With this in mind, the average lifespan of pebble dashing is estimated to be approximately 10 to 20 years.
Of course, this timeframe can and does vary according to the environment and other factors. Pebble dashing may remain intact for much longer if it is put up, maintained, and kept in conditions where it is not exposed to extreme climates. At the same time, if the pebble dashing is exposed to frost and extreme temperatures, it is more likely to become fragile and break off or crumble within just a few years.
Similar to other wall treatments, regular maintenance is essential for ensuring the longest possible lifespan of pebble dashing. Homeowners should inspect the pebble dashing every season and look out for any signs of damage such as crackling, chipping, and discolouration. If pebble dash is in need of repair, homeowners should contact a professional contractor to help them replace or repair any of the pebbles that are missing or loose.
In addition to regular inspections, other maintenance activities may be needed to extend the lifespan of pebble dashing. For instance, homeowners can help protect their pebble dashing by applying a sealant such as Everbuild 402 High Performance Water Sealant. Also at the first sign of flaking or damage this should be quickly repaired and not left for water to get behind the render and loosen it further.
Beyond regular maintenance and repairs, there are also a few steps homeowners can take to prevent their pebble dashing from breaking down too quickly. One of these steps is to make sure the walls are completely free of any debris, dirt, moss, or algae before pebble dashing is ever applied. Additionally, good drainage around the walls will help to minimize the damage caused by pooling water.
Pebble dashing is a great option for homeowners who want the natural beauty of stones on the outside of their home but do not want to commit to such a long-term investment. With an average lifespan of 10-20 years, pebble dashing is a great solution for homeowners who want a captivating look without the long-term commitment.
