A few cents of my own (some were already mentioned):
- Background image makes me feel like I am in an arcade back in the 80s :)
- The form lower left... don't have it open right away and block content. Most people that go to your site don't want to contact you right int he first second. First they have to find out if you are the guy they want to contact. Just like the car dealership I went to today, they are standing out there like vultures and get all disappointed when you continue to the service area.
- The call button... get off me, leave me alone :)
- Dawn's picture in the lower right: Well, she has an expression that tells me "oh no, someone called...". Make it a friendly, inviting face that I WANT to talk to.
- For me, it is too much text on the first page. Your home page is the entrance and give you the overview, suck you in the page, with details elsewhere. For example, I didn't even read it, so I can't comment to the content. Others may not have a problem with it, but generally the attention span of people is getting shorter by the day almost. Grab their attention with something they know will not take 3 minutes to read to decide if they click further. You can also apply some visitor analysis and see how many people will click-through to other pages before changing.
I've designed web pages in the past for customers and may be a bit picky there (semi-perfectionist):
- You logo has a wall missing. By now it distracts me so much because I always want to see the roof collapse...
- the top navigation - two things:
a) The white typo looks fuzzy on the background. Can't tell what it is, maybe font size, anti-alias settings or some other combination of things.
b) the mouseover blocks paired with the light blue color looks so nineties and outdated
c) a third thing I just notices, some mouseover buttons don't show right, they don't have red font, but blue or nothing or so. E.g."home" button under "how we do it" and "about" button under "about". There may be others.
I would also add a contact form other than the one that's called " no time for forms" (and then pops up - a form). I am sometimes too lazy to type up an email address, since yours cannot be copy and pasted.
Middle right, I like the "look familiar" box, although I would use one ?, and I think it should be "looks".
Also picky: the pics old-new at the bottom of "about" could use some form of frame. Would take the shadow away then. Reason is mostly the first picture: compare to the one right to it, and you think they are different sizes because of the white sky in the first one. Just a design aspect, though.
And lastly, before my wife gets mad because I am not coming down, I was briefly wondering if you would buy my house in Milwaukee. You may have to put it in more places which locations you target, e.g. under "sell your house".
