I need to install new lintels into my property above each and every external window and door (sad face) but my issue is this. The house is fully rendered (rough cast) and so to start chiselling off render to put in strong buys etc i am looking at having to possibly fully re-render the full house as patching up will not conform to my OCD after windows and lintels are in. Im racking my brains for alternative (hence this post) could i install stone lintels so as to obviously do the support work but also have them as a feature so as not to do patching up/fully re-render the house after new windows are installed or is there another route i could go down. Probably looking at 20k+ to fully render house which i dont have. Thoughts and opinions please............
