Frequently Asked Questions
How much siding do I need?
Measure each wall (height × width), add gable areas (triangle = 0.5 × base × height), subtract windows (avg 15 sq ft) and doors (avg 21 sq ft), then add 10% for waste. Most homes need 1,500-3,000 sq ft of siding.
What is the cheapest siding option?
Vinyl siding is the most affordable at $3-$8 per sq ft installed. Engineered wood ($4-$9) is the next most affordable. Fiber cement ($6-$13) offers the best value for durability. Stone veneer ($15-$30) and brick ($10-$25) are the most expensive.
