Questions

About this calculator

Is composite decking worth the extra?

It costs more upfront and much less to maintain. Over 15 years the totals often converge. The decision is usually about how much annual maintenance you want, not cost.

Why is railing so expensive per foot?

It carries code requirements for load and spacing, involves a lot of small parts and labour per foot, and is the most visible part of the finished deck.
