Hi, I have been in business for over 5 years now and started off just like you , cleaning domestic and rental properties.
Cleaning new buildings or builders cleans are a pain in the '
'.
The problem comes to what the builder expects of a builders clean and this always leave a trail of horrors.
The other problem is that 9/10 the builders/painters/decorators/electricians etc etc who all say they will be finished when you are ready to start cleaning WILL be on site even when they said they wont. Or even better, they are off site the day you do the cleaning and then low and behold they return the next day to do snagging or futher work and hey presto! more dust, more mess and then you as the cleaning company get blamed for not doing the work right and are asked to go back in to re-clean.
The other fact is that they dont want to pay much because - Uh its all new and shouldnt be too much to do!!!! Believe me, cleaning dust is a nightmare and continuous. Even when you have cleaned and people walk around the dust re-settles and then you get blamed for that too.
I take on builders cleans still but with a very very tight contract.
Beware, its not as easy as it sounds
