RSJs support your new extension or other construction to ensure that your property is structurally sound. They are crucial parts of your building work that mustn't be ignored, and must be installed by a professional. 

How much RSJs cost for supply and installation varies depending on the size, type and load-bearing properties, but in LS26 it ranges from £1,768 (Noble Homes based in WF10) to £1,896 (Lucinda arnold based in wf8).

Comparing extension builders estimates for fitting an RSJ gives you an idea of who will be better value but the best way to compare costs is to get actual quotes.
