Regardless of whether they are building a new home or renovating an existing one, your customers may have a difficult time deciding where to place their switches.
They may change their mind while the job is under way. They may even change it again. Every change results in lost time, increased costs and grumbling customers – and can have a knock-on effect on your other jobs.
Maybe they want switches in difficult or impossible locations. Even if they don't ask for changes, they may settle for switches in places where they don't really want them to avoid additional costs or delays.
