Why 4C wall-mounted mailboxes matter for San Diego properties

San Diego buildings deal with a mix of older construction, coastal conditions, and high parcel volume. Outdated wall-mounted boxes and improvised mail solutions create headaches for residents, carriers, and managers.

Replace rusted or vandalized wall boxes with secure 4C cabinets and parcel lockers
Upgrade aging indoor mail rooms that no longer meet USPS or ADA requirements
Reconfigure mail areas in lobbies, garages, and breezeways to improve carrier access
Increase parcel capacity to handle modern online shopping volumes
Create cleaner, more professional mail rooms that match the rest of your property

Instead of piecing together equipment from multiple vendors, you get a single contractor who designs, installs, and coordinates inspection for your 4C system.

How Postal Systems coordinates 4C projects in San Diego

San Diego properties often have tight lobbies, shared mail rooms, and limited staging space. We plan work around the realities of your building so residents and carriers can keep moving.

Review existing mail room conditions and any USPS letters you have received
Measure clearances and routes to design compliant 4C layouts with parcel lockers
Coordinate schedules with onsite staff, security, and building vendors
Stage equipment and debris handling to minimize disruption in active buildings
Arrange USPS inspection and complete punch-list items quickly

Our goal is a finished 4C system that feels like an upgrade for residents and an easier workflow for carriers and staff.

FAQs about 4c wall-mounted mailboxes in San Diego

Questions we regularly hear from boards, managers, and owners in this area.

Can you match the look of our existing mail room finishes? +

We review your existing finishes and recommend 4C cabinet colors and trims that work with your space. Where needed, we coordinate light framing or finish work so the new mail system feels integrated, not bolted on.

Do you handle removal and disposal of old wall-mounted mailboxes? +

Yes. Our team removes outdated equipment, handles disposal, and prepares the wall for new 4C cabinets. If patching or additional finish work is needed, we include that scope in your proposal so there are no surprises.

Can you coordinate with our general contractor on a San Diego renovation? +

Absolutely. We frequently work alongside general contractors and other trades, providing detailed layout drawings, equipment specs, and schedules so mailbox work fits smoothly into the overall project.

Lead times can vary based on equipment selection and building schedules. The sooner we review your site and USPS requirements, the easier it is to plan a smooth upgrade with minimal disruption to residents.
