James Hardie Plank Lap Siding & Anlin Window Installation in Castro Valley, CA 94546

The homeowners here wanted a tougher, better-looking exterior for their Castro Valley home, particularly where a newer addition meets the original structure. Our crew stripped the old siding back to the framing, rebuilt the wall assembly from the sheathing out, and finished it in James Hardie lap siding with new Anlin windows. The result is a clean, fiber-cement exterior in Night Gray with bright Arctic White trim that gives the entry and garage a crisp, defined edge.

We tore off the existing siding and trim around all doors, windows, and corners, then inspected the wall cavities for dry rot and repaired the damaged framing we found. New R-13 Owens Corning fiberglass insulation went in between the studs, followed by half-inch exterior plywood sheathing for shear strength - work that passed the city's shear-wall nailing inspection. Over that we installed HardieWrap weather barrier, Forti-Flash rubberized flashing at the window and door openings, and metal Z-flashing to keep moisture out of the new system.

The siding is James Hardie ColorPlus Statement Collection in a smooth profile, running from where the addition starts across to the front corner of the garage. We trimmed the openings and corners with 5/4x4 and 5/4x6 Hardie ColorPlus trim, and installed six Anlin Catalina new-construction vinyl windows carrying the Infinit-e glass package - triple Low-E coatings with argon fill for year-round efficiency. To tie it all together, we painted the eaves, fascia, and foundation to match the new color scheme.
