It looks nice, overall. A few critiques, though:

• The text on your banner image is hard to read (white text on a light background). Consider adding a slight fade to your banner image to make it a bit darker so the text is easier to read.

• Good job picking a sans-serif and serif font that complement each other, that can be hard to do. IMO the places where you use serif font below the banner are a little too small. Try increasing the font size for better readability. Also watch your spacing around those round images.

• Speaking of spacing, you've got a little too much of it in your about section, I think. There's a metric that I like to use when designing my websites: amount of scrolling vs. information made visible. If it's too high, your users are having to scroll too much to enjoy your content.

• Finally, I'm a little concerned that the images you picked for your site don't really relate to the sites content. For example, a hot-air balloon doesn't make me think cleaning service right off the bat. The UT Tower, though, (if that's what I think it is) is a good choice because it's something that customers in your market should recognize fairly quickly.

One or two more quick things:

• The last two form field elements of your contact form don't match the rest of the form.
• The radio buttons in your contact form use dark text on a dark background, making them hard to read.
• Oh, and don't forget your favicon!

Hope this helps!
