The Improvement Ledger, No. 4 of 20<\/p>\n
Every pattern in this series says the cheaper option wins. Here is the exception, and the arithmetic of why it is the exception is the most useful math lesson in the course.<\/p>\n
Entry No. 4 is the same 1,250 square foot re clad as the vinyl entry, in a material made of cement, sand and cellulose fiber pressed into planks. The 2021 national Cost vs. Value data: $19,626<\/b> in, $13,618<\/b> back, 69.4 percent<\/b> recouped, the best siding number on the table.<\/p>\n
Here is the arithmetic that makes this entry famous inside the course. Fiber cement cost $3,050<\/b> more than vinyl in the 2021 data and returned $2,303<\/b> more. Those upgrade dollars recouped at 75.5 percent<\/b>, a better rate than either project’s overall average. That is why the pricier option wins its only victory in the book: the premium itself is the best performing money in the deal. When a client asks whether the upgrade is worth it, this is the shape of analysis that answers it, marginal dollars against marginal return, not sticker against sticker.<\/p>\n
The product review is glowing even from a thirty year contractor: super durable, one of the few building products of its era that never had a failure problem, low maintenance, and with the factory finish, paint warranties running to fifty years. It hangs like wood, solid and tight, no thermal sliding games, though it is heavy, brittle in long lengths, and wants an extra pair of hands on the crew, which is part of the price gap.<\/p>\n
The printed spec: 1,250 square feet of fiber cement siding including trim boards, factory primed and painted. Fiber cement is the generic term, several brands manufacture it, and the course deliberately names none. The factory finish matters: prefinished planks carry the long paint warranties and arrive ready to hang, which is how the fifty year number becomes real.<\/p>\n

Why has the gap to vinyl narrowed enough for the premium to win? Petroleum. Vinyl is an oil product, and its price has ratcheted up through every oil shock without ratcheting back. Cement has climbed slower. The instructors’ price memory from their contracting years, quotes that once held thirty days shrinking to fifteen during oil runs, is the texture behind the tables. Materials do not just cost what they cost. They cost what their feedstock did lately, and the trend line has favored fiber cement for two decades.<\/p>\n
The 2025 San Francisco metro figures: job cost $24,197<\/b>, resale $26,573<\/b>, a 109.8 percent<\/b> recoup, versus 130.4 percent for the Pacific region and 113.7 percent nationally. Read that again: in the current data, in every geography, fiber cement siding returns more than it costs. It is one of only a handful of projects on the 2025 table that clears its own invoice, and the methodology caveat below applies, but the direction is unambiguous across every cut of the data.<\/p>\n Cost recouped, 2025 report<\/p>\n
