The articles say homeowners may be able to earn money by keeping certain building materials and scrap items instead of discarding them during renovations. They describe how items such as bricks and roofing tiles, as well as plumbing-related materials like copper piping, may have resale value. The pieces also mention that older fixtures and equipment—such as an old boiler—can be sold for money rather than being thrown away. The common theme is that materials left over from building work can sometimes be collected and purchased by scrap dealers or reused where possible, potentially turning waste into a source of extra income. One article highlights that roof tiles may be particularly valuable in some cases, with a stated high potential price, while other examples focus on typical scrap categories that may fetch hundreds of pounds depending on condition and market demand. Overall, the reports present selling discarded materials as a practical option for homeowners undertaking repairs or refurbishment.
