I think your website looks good. Easy on the eyes, and easy to navigate.
Although, as a copywriter one thing that hit me right away was the "BENEFITS OF CHOOSING US" box. It's listing "features" more than "benefits."
A feature is what you do... A benefit is what it's going to do for me.
Here's a couple examples for you. From your home page:
"Same-day and next-day service arrangements" (feature)
"which means your home can be professionally cleaned before you go to bed tonight." (benefit)
"Specialized detergents and high-end equipment." (feature)
"which means we can eliminate even the worst messes, for you." (benefit)
Of course, I don't know who your clients are, so you would need to do a little research to determine what benefits they desire. Then adjust your copy accordingly.
But these are a couple basic examples of the difference between features and benefits.
Hope this helps.
All the best,
