Frequently Asked Questions
Why should I add a waste margin to my materials estimate?
Standard flooring and tile installations require cutting materials to fit room edges. A 10% waste margin is recommended for rectangular layouts, and 15% is recommended for diagonal layouts.
How is square footage calculated for a circle?
The area of a circle is A = π × r², where r is the radius in feet.
