Company name has a slight issue. Family Restoration to me means fixing dysfunctional families! Suggest that the business name be clearer. Eg. Elwood Family Home Restoration.
Create a short slogan. Long slogans look odd under the company name and logo.
Always go back to the consumer benefit and your strength. The benefit for consumer is quite clear- Happiness - because a newly remodelled home gives a family more family time and enjoyment. If one has a nicer place, they like to come home and not go out so much. Less arguments and fights too!
As a family business - your strength is : you know how important family life is. You work and live together! You're the best advocate. In this day of family fragmentation, the time you spent becomes more and more precious and rare. So, marry the two factors.
Go along the lines of :
Elwood Family Home Restoration
Creating spaces for a better family life
I'm sure you will have some nice ideas of your own. Think back what people say about the services your family provide as well.
Actually I'm an opponent of slogans because I don't believe people market from slogans effectively. It would be better to develop your brand vision, mission statement, core values of what you stand for, build your product around the core value. Eg. if one of your core value is family togetherness. Then, think about how you develop products that builds that togetherness - create your design and provide concepts for BBQ pits, Living room concepts, Island Kitchen set-ups etc. Then you can really walk the talk.
