After helping my brother with his extension, I saw how quickly unexpected issues can increase the budget when nobody checks everything properly at the start. This time I want to do things differently. Does anyone know a London company that provides a detailed assessment of your project before work begins? Honest recommendations would be greatly appreciated.

Been there — helped a brother with an extension once and the “small” surprises piled up fast because nobody checked the awkward bits early on. A proper pre-work assessment would’ve saved a lot of back-and-forth. For London, I’d take a look at visit website it seems like the kind of place that actually looks over the job properly before anyone starts.
