Really?? How grotty is your oven??!! I give mine a wipe out after I use it and a bit of a scrub each month or so and it's fine. Man... I would clean your oven for $150!!
So $150 is normal but at the top end?
I just spoke to a guy who will take the whole thing apart and clean between the glass, do the range hood, replace the light etc for $150. He said it usually takes him about 3 hours and he promises that when he finishes it will look like it is new.
My cleaner brings a mask and does mine, I pay her $50 for 3 hours once a week and she spends 1.5 hours doing the general clean/washing/making beds and the other half doing her deep clean on whatever I've requested. She used all the deep clean time so I guess it costs me $25? I found her on gumtree.
