What does DIY mean?
DIY stands for 'Do It Yourself'. In home improvement and remodeling, it refers to the practice of homeowners planning, measuring, sourcing materials, and executing construction or renovation tasks themselves instead of hiring professional general contractors. DIY projects range from simple cosmetic painting or tile backsplashes to complex deck building. While DIY can save substantial contractor labor fees (which typically constitute 35% to 50% of remodel invoices), it requires time, tools, and careful math. Our Home Planning Hub calculators are designed to help DIYers confidently estimate material quantities to minimize waste.
