JKC Construction Inc. has completed projects for homeowners in Seaside and Marina. On this stretch of Monterey Bay, salt air and moisture shape what lasts, and our licensed, bonded and insured team (CA #1090260) builds with that in mind, from bathroom remodels to new siding, windows, decks and fences. Call (831) 620-2497 or request an itemized estimate below.
Built for salt air
Salt air and moisture break down wood siding, window seals and metal hardware faster than inland. Fiber cement and vinyl siding resist rot better than wood, corrosion-resistant fasteners and hardware last longer, and every window and door opening needs to be sealed against wind-driven rain. Inside, bathrooms need ducted exhaust ventilation and proper waterproofing to keep moisture out of the walls.
Permits in Seaside and Marina
Seaside and Marina are separate cities, and each has its own building permit process; neither is permitted by Salinas or Monterey County. The City of Marina accepts all building permit applications online through its permit portal. We confirm the requirements for your address and handle the application as your licensed contractor.
