This is just a follow up as to the keywords that I would add. I wrote the keywords based upon the copy that is currently on that specific page of the site.
I noticed that you don't have any keywords on the following pages of your website:
Home
Products
Gallery
Free Estimate / Quote
References
Contact
Guarantee
Keep in mind, that keywords are not the end-all, be-all for your website to be placed high in the rankings of search engines, it just helps the search engines when they view your website to know what content that the specific page is about.
Another note: if you want your company to come up on Google for a specific keyword and it's not in the list that I've written down, then that means that you need to write some copy that includes that keyword.
Here is a list of keywords that you should add to each page respectively.
