Estimates only
Every result on SureAmount is an estimate based on the measurements you enter and typical product data. Real jobs vary, so check your measurements and buy a little extra.
Check local codes and a professional
The calculators work out quantities and cost only. They don't check structural strength, loads, spans, drainage, electrical work or whether you need a permit. For those, check your local building code and ask a qualified professional.
Product data varies
Coverage, bag yields and densities differ by brand and product. Where a calculator has a field for it, such as paint coverage, gravel density or the area a box of tile covers, type the figure from the label.
Safety
Follow the safety instructions on every product you use. For example, wet concrete can burn skin, so wear gloves, long sleeves and eye protection when you mix and pour it.
