After having our local cluster mailbox broken into I looked into getting a new more secure one. I was very happy with this installer. The tricky part was working with the local post office and coordinating with neighbors. Process for getting a new cluster mailbox 1) Talk to your local mail delivery person to determine which houses share your mailbox. 2) Talk to your local post office to get a list of legit installers that they have worked with in the past. 3) Google the installers to see if they have good/bad reviews or complaints from the Better Business Bureau. 4) Send out emails requesting bids. Boxes usually come in 8, 12, 13 or 16 compartment units. 6) Talk to each house to see if they are willing to chip in for a new mailbox and show them the choices. If a new 12 compartment box cost $1500 and 10 houses share the box then each house will have to contribute $150. 7) In our case the installer wanted at least 50% down payment. I sent a letter to the installer letting them know what unit we wanted with enough checks to cover 50%. 8) Within two weeks the unit was installed. The balance was paid once installation was complete. The installer had someone from the local post office meet us after installation to change the master lock for them. All the compartment keys were given to the neighborhood focal for distribution. 9) Taped a note on the box so that your normal USPS delivery person can coordinate with the neighborhood focal to determine which cluster box compartment maps to which house number. 10) Neighborhood focal hands out keys and collects any remaining checks. If someone can't afford the entire amount accept a post dated check then cash on post date. read more
