A well-executed siding project holds its value for decades. A poorly planned one can cost more to fix than the original project was worth. Here are the things Bay Area homeowners consistently get right — and wrong — on these projects.
What a Quality Siding Project Includes
- James Hardie certified installers
- Wood, fiber cement, and engineered wood options
- Complete moisture barrier installation — no shortcuts
- Matching existing profiles on historic homes where possible
- Trim, flashing, and caulking included — complete system
The Most Expensive Mistakes
Choosing a contractor based on price alone is the single biggest siding mistake. In the Bay Area, a bid significantly below competitors means something is being cut — labour quality, material specification, permit compliance, or all three. The cost to fix a failed siding project almost always exceeds the original project cost.
The second most common mistake is making design decisions after construction has started. Every change order after work begins is priced at a premium and disrupts scheduling. Make all decisions before signing the contract.
Questions to Ask Your Contractor
- How long does siding last?
Fiber cement siding carries a 30-year manufacturer warranty and realistically lasts 40–50 years with proper paint maintenance. - Can you match my existing siding?
For HardiePlank, we can match most standard profiles. For custom wood profiles on historic homes, we work with millwork suppliers. - Do you handle painting of new siding?
Yes. We can paint new siding as part of the project. Most clients prefer the all-in approach.
Maintaining Your Investment
Most quality siding work includes a workmanship warranty. Keep all permit and inspection documents, photograph completed work before walls are closed, and follow any maintenance recommendations. Regular maintenance on exterior work dramatically extends lifespan in California’s varied climates.
