Improper painting techniques can compel walls into taking fate into their own hands, changing colours as often as a mood ring on a chameleon. Appease house hedges with today's Groupon: for $129, you get interior painting services for one room sized 12'x15' or smaller, with walls up to 10' high, from Hamilton House Painters (a $297 value), valid in Hamilton, Burlington, and Oakville.

Hamilton House Painters upgrades domestic bliss with more than 25 years of painting experience in homes of all sizes. All aspects of an interior project, from drywall taping to floor and furniture protection and post-work cleanup, are completed with a sharp attention to detail. A top-quality finish is routine, leaving walls blissfully free of brushstrokes, unlike the sweeping, if sloppy, canvases of Monet or the dappled contour of pointillist face-painting. Though Hamilton House Painters does not supply the paint, it offers a 35 per cent discount for dwelling-decorators who use General Paint, providing a multitude of colour mixes from "glossy pickle" to "pterodactyl's egg blue."
