the animations are good, the site is fantastic, .... but (just my ten pence worth) you need a little bit more info, perhaps you could scroll the text into the animation somehow? then you would be drawn to reading it if it was short and pithy
but its definitely a creative site, you could also add some call to action with it ie, call now for quote , or click here to get quote - linked to a simple contact form to get details, the website in pure marketing terms, aside from explaining what you do etc should really get you peoples details so you can ring them, email them, call on there home and gain custom, its unfortunate if people just browse your site and leave with no action taken, if you can just capture their info somehow, you will have an endless stream of potential customers to tap into, as i find with my site - site traffic can be good, but the actual conversion rate very low so its getting that conversion percentage higher, but that site is very good you should get somewhere, like nat says too, get it optimised, im sure the lad who can do all that flash animation should be able to optimize
Good Luck
