Can I run two related service businesses under one LLC?

I currently have an LLC for a small home renovation business, and recently I started getting requests for a related service, property maintenance and seasonal upkeep for the same clients.

Since the customers and type of work overlap, I am wondering if I can just run both under the same LLC instead of creating a separate one.

On one hand, it seems simpler to keep everything under one entity, one bank account, one set of books, etc.

On the other hand, I am not sure if mixing two slightly different services under the same LLC creates any issues with liability, taxes, or just general organization.

For those who expanded into related services, did you keep everything under one LLC or split them out? What made you decide one way or the other?
