There are a few key factors to consider when pricing up the cost to remove the render from your house or commercial building. Firstly, if your building is listed, it will need listed building consent and a skilled craftsman to carry out the work so minimal to no damage occurs to the underlying fabric of the building. Unfortunately, where cement renders have been applied to traditional buildings, a lot of damage behind the render has already occurred. Secondly, If you remove the render and keep the masonry visible, you would likely want to have it cleaned before any pointing work takes place. Masonry cleaning would incur extra costs, and possibly a specialist masonry cleaning company would be needed. This would depend on the method of cleaning required for your building. Listed building owners must follow strict guidelines, and the use of chemicals or abrasive methods like sandblasting is not suitable. A Doff or ThermaTech superheated steam cleaner is used; these types of masonry cleaning are acceptable for Listed buildings. Finally, Scaffolding costs, waste removal and protective measures need to be taken into consideration. The placement of the skip and distance to travel with the waste has to be factored in. If your windows need boarding or the conservatory needs protecting. Your live wiring would also need disconnecting and needs to be made safe for work to be carried out. With all these factors and more to take into place, estimating realistic costs would be difficult, but for the render removal, waste removal and hot lime pointing costs on a traditional or listed building, you would be looking between £75.00-£225 per m2. This price varies depending on the masonry type and if any pointing work or resetting of any masonry is required.
