Why do cost guides disagree?
They measure different things. An estimate prices one defined job at today's rates; these figures are what owners actually paid, across every size and kind of job in the category. A full job on a large house can sit well above the typical figure, and a small one well below it. Your own quotes, compared line by line, are the price that counts.
Measure your job with the calculator, then put your quotes side by side in the quote worksheet.
Have prices moved?
Lumber cost 7.6% more in August 2026 than a year earlier (Bureau of Labor Statistics producer price index, preliminary).

Before you compare quotes
If a quote is well above the typical $4,750, ask what is in it that the typical job is not. Separate a new deck from resurfacing. Compare footings, framing, boards, railings and stairs.
