How Rockville's Climate Affects Siding Replacement
Rockville's extreme winters demand insulated siding with meaningful R-value. Insulated vinyl (R-3 to R-6) reduces thermal bridging through wall studs and prevents the freeze-thaw moisture cycling that degrades standard siding. Proper moisture barrier installation beneath the siding is critical — inadequate house wrap allows water infiltration that freezes and expands inside the wall cavity.

- Home size and stories: Two-story homes require scaffolding, adding 15–25%.
- Material choice: Fiber cement costs 60–80% more than basic vinyl.
- Trim complexity: Complex trim and corner work adds $500–$2,000.

Maryland requires home improvement contractors to hold a Home Improvement Contractor (HIC) license from the Maryland Home Improvement Commission (MHIC). Confirm active general liability insurance (minimum $1M) and workers' compensation coverage. Get written proof of both before work starts.
