Steve did a bang up job on his review, I just have a couple of things I'd like to season the stew with:
First off all, it looks like it's built on Wordpress. Well done sir, well done. That's 3/4 of the battle right there. It's a good, user friendly CMS to use for sure. My second favorite
The "Art" part of your logo, while definitely visually attractive and memorable, is missused when it is placed in those line of images in the header. It kinda looks like your logo is just "Tile", then you have a red picture, a blank white box, and the rest of the pictures. You know what I mean? The images could also benefit from being place in a slideshow, or a mini gallery somewhere else on the page. Like where the pic of the vanity is. That would be a pretty good spot.
The main copy could use some trimming and more sub headings. While it certainly is good copy, it's not easily scanable. I want to know what exactly every paragraph is about right away so I don't have to read it if it's not important to me. I would completely eliminate the credit card part since it is on the sidebar as well. No need to waste valuable screen space with duplicate info.
Also, you shouldn't have to tell your user how to use the site. (the rectangle at the top... line). If you think people might miss the navigation without being prompted to where it is, you should change it so they could notice it if the power went out.
I don't love how the Monthly Special text and the stuff that follows really breaks up the flow of the copy. I'd move that stuff to the top right of the sidebar, and make it higher on the food chain visual wise.
Absolutely love the first paragraph, very strong. Change the heading to something more.....catchy? I hesitate to say catchy because it can come off salesy and cheesy, but something that will really grab the visitor.
I like the image at the top, and I personally think it would be a good place for a mini gallery or slideshow. Bring the images down from the header and stick them in a slideshow here.
Not a giant fan of the Contact Us section, because it doesn't really jump out. It's got kind of a Christmas tree shape going on. Make the Contact Us more prominent, dump the we are located line (but keep the Fort Collins under neath the number) Make the "call for free estimate" area really pop if that's the main goal of your site.
The Search box is most often (almost always) found in the top right hand corner of a page, so it's not very noticeable. Also, the titles of the Blog sections are about the same size, color and font as the blog post titles themselves, which makes it all kind of blend together (again not very user friendly)
Good Title Tag, and good Description Tag. The only thing I would work on (bear in mind I haven't researched these keywords at all) is that you may be targeting too many keywords, and they seem to be very broad head ones. Do some research and possibly modify the list or dump some.
Also the keyword density isn't very high for the page.
Hope that helps you out some, any questions and I'm quite certain Steve or myself will come swinging in to the answer
