CARPET HAS DARK STAINS AROUND PERIMETER OF ROOMS AND AT HEATING REGISTERS
Dark stains on carpet around room perimeters and at heating registers, commonly called “carbon black”, are an occupant use and house location issue. Sources of carbon rarely relate to work and material supplied by the builder.
None. · Stains resulting from normal wear and tear or improper maintenance are excluded from the statutory warranty.
The homeowner shall ensure that furnaces, fireplaces, and other combustion appliances within the home are not leaking products of combustion.
Dark staining often results from airborne carbon material settling out on synthetic or magnetic surfaces such as televisions screens, carpets and magnetic seals on refrigerators. Burning scented candles contributes to carpet staining. Light-coloured synthetic carpets accentuate this condition. See Also: 12.6 SPOTS OR FADING ON CARPET 12.7 CARPET NOT UNIFORM IN COLOUR
