While polite people, I must say that it is a complete half job. I purchased this on Groupon, and $200 later (discounted from $350) the "dusting" consists of using a feather duster. Everyone in AZ knows that doesn't work, so now I'm $200 poorer and still have dust. Buyer beware -- also, their website says they don't give price ranges, only exact numbers. Guess what -- they give ranges.
UPDATE: I just now see a response from this owner well over a year after I posted this and NONE of it was discussed with me.
Feather dusting discussion??? Really???? How about 100% of the people who hire a cleaning company just want dust gone, not the method.
And yes, we did talk specifically to this owner who tried to shake us down for more money with the same lie - as you can see from the other poster Britny I paid well more than she did. We TRIED rectifying with this company but, as everyone can plainly see, they wait well over a year to respond to their customer -- and then do it with complete falsehoods and lies... but at least they'll try and justify their poor job with "dusting techniques".
Updating my recommendation: Avoid at all costs.
