Why what we do matters


Before you purchase, we help evaluate how well a property or building can be adapted to meet your needs. We work with you to bring the vision of your project to life by organizing a team that includes architects, designers, and any other vendors needed. We layout an efficient project plan and work through the permitting process to set up any necessary testing, inspections, and more. When we get involved early in a project, we anticipate and help minimize any challenges.

Construction Management

Whether you plan to build from the ground up or renovate, we have the team to get you there. With years of experience, we manage your project with communication in mind. We coordinate everyone involved, which means we work closely with you along the entire process with architects, designers, crafters, and tradespeople to ensure that the project stays on schedule and within budget.


We call it Prime Care and it's our commitment to you long after the project is completed. We offer a customized peace of mind maintenance program to keep your home in its best condition. This can include scheduled maintenance, annual inspections, and routine services to preserve the appearance and integrity of your home and ensure that all systems run smoothly.

If you are looking for a General Contractor that is a team player and will get the job done right the first time, your search is over."

As a tradesman who takes pride in providing high-quality installations, I find joy in taking on projects with Prime Building & Development. No details are overlooked or considered too small. The team at Prime always puts the client first and demands that all sub-contractors do the same. The management at Prime has worked hard to assemble a team of like-minded people who work well together. The end result is what we are all looking for; a client with a smile and a strong sense of accomplishment through teamwork.

Joe and Prime were amazing from start to finish when fixing damage to my house due to ice dams. They give an upfront DETAILED quote so that you know EXACTLY what you are getting when you sign up to use their services. From there they EXECUTE to perfection - we left our house for a week vacation and everything was completed on time and on budget, and the house looked and worked better than ever before. Thanks again to Prime for a beautiful professional job.

I approached Prime Building because they were a solid foundation company with an excellent track record. The respectfulness their employees and subs displayed was refreshing.   I went from doing small in and out jobs to giant additions and luxury homes.  I found working with them to be an excellent experience.   I could not help but notice how clean and organized their job sites were.  The result of my interactions with PRIME were a great friendship and partner.  Due to strong efforts by Prime I continue to stay busy and We continue changing people’s homes and lives one at a time for the better.

As a developer, builder and licensed general contractor I am very demanding when it comes to sourcing labor and new companies to work with.  Prime, in particular Joe were critical in getting two custom townhouses built in Brookline for us. Joe's professionalism, attention to detail and uncanny organizational skills allowed him and his team to deliver quality results on time. This is what sets Joe and his team at Prime apart from the rest of the crowd.  I look forward to our next project.  Thank you Joe and Prime Building & Development Inc.

As a Designer I have worked with Joe on both new construction and large renovation home projects. He is a delight to work with because he stays focus on the teams goal and is 100% always looking out for his client.

What makes Joe Gearhart at Prime Builders & Development so valuable on your next project, is that he sees the Big Picture, but in very small minute details from the beginning to the end. Clients talk about their projects with compassion, emotion and focus on their dreams for the space in the future. It is the Design team and Contractor’s responsibility to layout the road map. Joe’s breathe of knowledge in construction enables him to give you a realistic idea of cost and options to get you where you want to go. His on hands management of projects is in my mind an insurance to you that no matter how big the project is no detail will be overlooked.
