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 TR26 it ranges from £1,320 (Smudge Construction Ltd based in TR13) to £1,800 (Peninsula Property Refurbishments based in TR15).
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.
