Highly recommend! After our mailbox was hit, we called and they responded quickly with helpful feedback. They made it easy to decide on next steps based on the damage, the materials we had, and our HOA requirements. Super fast, knowledgeable, and easy to work with!

Jay and his team at Big Bore are fantastic. I will call them first and only them for any sign, mailbox, CBU work needed. They always go above and beyond for me. They have even done things to help me out that they don't typically do. Park benches, access gates and just extremely helpful when I need something.

I cannot say enough great things about Mailboxes by Bob!

They are very quick and incredibly knowledgeable about mailboxes, Community Entrance signs and street signs.

They have helped me countless times in my job as a Community Manager, and they are always my go to company whenever I have a question.

They are super easy to work with and they make me look good with their great customer service, and quick turn around time.

Morgan did an excellent job for us on a snowy, windy day … not only installing new but removing old mailbox snapped off by Wayne County plowjockey

Thanks “ Jay” for guiding us in our emergency need and expediting the job

Jay was a great communicator and very friendly. Reached out for a quote yesterday, and my mailbox was completely replaced today. The installation looks very professional. Do not hesitate to work with this company!

I had been on my husband for over a year to get our mailbox fixed and then I finally had to step in. Googled "mailbox repair near me", Mailboxes by Bob popped up first on the list. Clicked on the contact and got a response same day from Jay and he came out the next day and had our old broken and swaying mailbox out and a beautiful new one in super quick. Very happy and definitely recommend.

A bit disappointed by this service. In setting the appointment up, I sent a large photo of our damaged mailbox, and since there were no follow-up questions asked, I assumed this was sufficient to clear see the multiple issues with our mailbox.

However, after the tech left, I noticed that there was still a broken spot on my mailbox. I asked to have this fixed but would told I would owe more money for another service call and more parts.

I would recommend being very clear with customers as to what you plan to fix and what your quote covers. This was not a cheap service call to start with and then to have it half done felt like such a waste.

Jay was awesome in helping me pick out the best mailbox based on my preferences. Communication was easy, payment straightforward, and installation was a breeze. I didn’t even have to be there for it, which was even better and allowed me to stay at work. I will definitely use their services again in the future and would recommend anyone who wants to upgrade their mailbox to choose this company. Thank you again!
