Cluster mount mailboxes are a practical, secure, and space-efficient solution for communities, commercial buildings, and property managers throughout Houston. These mailbox systems are built to serve multiple residents or businesses in a single, centralized location—making them a favorite among HOAs, apartment complexes, and retail centers. With built-in locking compartments and parcel units, cluster box units (CBUs) simplify mail delivery and reduce the risks of lost or stolen mail.

As a trusted local locksmith company in Houston, we specialize in both the installation and repair of cluster mount mailboxes, including lock replacement, compartment repairs, and full unit swaps.

Cluster mount mailboxes are designed for centralized delivery and high security. If you're managing an apartment complex, HOA, or business park, CBUs help consolidate delivery while reducing costs and theft risk. Mail carriers also prefer them because they reduce time and travel between addresses.
Most cluster boxes come with integrated locks, outgoing mail slots, parcel lockers, and durable construction. This all-in-one design means residents or tenants get secure, convenient access while the property remains neat and organized. They're also ideal for retrofitting outdated mailbox posts or pedestal units that no longer meet USPS specs.
Installing a cluster mount mailbox requires precision tools and a level surface. Here’s what we use on the job:
We bring everything with us and prepare the surface if needed. Whether installing in a new development or replacing an old box, we’ll make sure the job is done right the first time.

Our mobile locksmiths in Houston offer full-service cluster mailbox repairs, whether it’s one broken door or a full unit that needs a rebuild. We work with property managers, HOA boards, and businesses to deliver efficient solutions including:
We use manufacturer-approved parts for all major brands including Salsbury, Florence, and Architectural Mailboxes. Most jobs are completed same-day, minimizing inconvenience for residents or staff.
If your cluster mailbox is outdated, missing multiple parts, or no longer meets USPS standards, replacement may be the best option. Frequent issues, poor alignment, or repeated key problems are also signs that a new unit may save money long-term. We’ll provide an honest assessment so you can make an informed choice without pressure.
All cluster mount mailbox installations must comply with USPS STD-4C regulations for security, accessibility, and positioning. We follow these standards along with local Houston building codes to ensure your installation is 100% compliant.
This includes proper mounting height, slab requirements, ADA compliance, and approved lock systems. Our team will also check with your HOA or property manager to ensure design consistency where required. Avoid code violations and mail disruptions—let us handle it for you.
Cluster mailboxes come in a wide range of configurations, finishes, and layouts. Whether you’re matching a luxury apartment complex or retrofitting a small commercial plaza, we offer units that fit your needs and design preferences.
