New siding transforms a home's appearance and protects it from the elements. Here's a complete guide to siding materials, costs, and how to choose the right contractor.
Signs Your Siding Needs Replacement
Siding typically lasts 20–40 years depending on material and maintenance. Signs it needs replacement: warping or buckling panels, rot or soft spots (especially on wood siding), fading that doesn't respond to cleaning, increased energy bills (failing siding allows air infiltration), mold or mildew that keeps returning, and visible gaps or cracks that allow water intrusion.
Siding Material Options
Vinyl siding is the most popular choice — low maintenance, affordable ($8,000–$16,000 for a typical home), and available in many colors and profiles. Fiber cement (James Hardie is the dominant brand) is more durable, fire-resistant, and pest-resistant at $12,000–$22,000 — the premium choice for most homeowners. Wood siding is beautiful but requires regular painting or staining and is vulnerable to moisture and pests. Engineered wood offers wood aesthetics with better moisture resistance.
Why Fiber Cement Has Become the Standard
Fiber cement siding has taken significant market share from vinyl over the past decade for good reason: it looks better (especially the lap siding profiles that mimic real wood), it's more durable (won't crack in cold, won't melt in heat), it's fire-resistant, and it holds paint better. The 30-year warranty from James Hardie is industry-leading. The higher upfront cost is offset by lower maintenance and longer life.
What's Included in a Siding Replacement
A complete siding replacement includes removal of existing siding, inspection of the sheathing underneath (and replacement of any damaged sections), installation of a weather-resistant barrier (house wrap), installation of new siding, and replacement of trim boards, corner pieces, and J-channel. Make sure your quote includes all of these — some contractors quote siding-only and add the rest as extras.
The Importance of Proper Installation
Siding is only as good as its installation. Improperly installed siding — gaps at seams, inadequate fastening, missing flashing at windows and doors — will fail prematurely and allow water intrusion. Fiber cement in particular requires manufacturer-certified installers for the warranty to be valid. Ask your contractor about their certification and installation process.
ROI and Resale Value
Fiber cement siding replacement returns approximately 68% of its cost at resale nationally. Vinyl siding returns about 67%. These are solid returns for a project that also dramatically improves curb appeal and reduces maintenance. New siding also makes a home more marketable — buyers notice and appreciate a home that doesn't need immediate exterior work.
