I'm throwing my 2 cents here because I see you've gotten some good advice and some not so good advice, to say the least.
Your target market is not really part of the Internet era and therefore less likely to search you out on the internet but they do use Google and Facebook.
My suggestion would be a combo of print marketing and very targeted Adwords and Facebook ad campaigns.
Also important to list all of your locations on Google so people can find them on Google maps.
For the kind of work you offer I recommend you use information marketing because you need to educate people on why they should buy this home improvement in the first place.
So you need something that will educate your leads and customers on a regular basis.
Hope this helps.
