Renovation (also called remodeling) is the process of improving a broken, damaged, or outdated structure. Renovations are typically either commercial or residential. Additionally, renovation can refer to making something new, or bringing something back to life and can apply in social contexts. For example, a community can be renovated if it is strengthened and revived. Wood is versatile and flexible, making it the easiest construction material for renovations, and wood buildings can be redesigned to suit changing needs. Few homeowners or professional remodellers possess the skill and equipment that is required to alter steel-frame or concrete structures. Forest certification verifies that wood products have been sourced from well-managed forests. Most certification programs provide online search options so that consumers can find certified products—the Certificaton Canada program includes a search option for all of the certification programs that are in use in Canada.
