Hopefully none of these photos resemble your home. But if they did!
Not very many people do their research before they decide on a company. What usually happens is they call around and find the cheapest company. All things being equal, this would be t a great method. Unfortunately , NOT ALL THINGS ARE EQUAL. Not all cleaning agents are the same, not all equipment is the same and most importantly not everyone takes pride the same or has the same work ethic. So you see NOT ALL THINGS ARE EQUAL. This is the main reason that doing your research, finding references or referrals, asking to see before and after photos and asking questions (as many as you can think of) are essential. .
So give your self A LOT of credit for doing your homework!!!!
