The Sew Carterton, Centreways Takeaways, Cafe Ole and old From Wags to Whiskers buildings will be the first to benefit.
It was hoped the makeover would help regenerate High St and "entice people to move into those spaces", Mr Crimp said.
"Everyone is very keen to improve it and it's exciting to see how well Martinborough and Greytown have developed over the years and Featherston is also seeing some revitalisation as well, which is great.
"I'd like to see all the shops full and occupied."
CDBI hopes to secure the help of professional painters, who will be able to oversee work on a particular building and supervise teams of volunteers.
The group also hopes to highlight the history of the buildings, reduce redundant signage and improve landscaping.
Holloway St was a good example of what landscaping could achieve, Mr Crimp said.
"We are not wanting to sanitise it and make it too trendy ... and it's also important that we really celebrate the architecture. So we've referenced Resene's heritage colours as well as some modern ones."
The response from building owners so far had been "very, very excited" and encouraging, Mr Crimp said.
