We are Building Doctors

Unexpected damage to your building threatens your safety and your finances. Our team will diagnose the problem, prescribe the repairs, and guide the process to restore your building, your safety, and your investment.

J2 Building Consultants is a team of engineers, architects, and project managers that specialize in helping building owners manage remediation projects for condominiums, apartments, and commercial buildings. 
Like a doctor, we have developed a simple 3-step process to make communities healthy.
Diagnose, Prescribe, and Treat. 

Get A Diagnosis

We investigate, interview, look at building history, and create a plan to help you understand what is wrong with the building. 

Our Diagnosis Process

Fill Your Prescription

We develop scope of repair based on your budget, code requirements, and extent of the damage, and we get your input on updating the look of the building to increase property values.

How We Prescribe

Begin Treatment

We act as your representative when consulting with a team of specialists. We make sure your project is completed correctly, on-time, and within budget.

Treatment Process



We have developed a strategic process to diagnose the root cause of the problems with your building, prescribe cost-effective repairs, and provide leadership and expertise to the restoration process. We manage the project from start to finish so you don't have to worry about things getting done. Our clients and building residents appreciate the stress-free approach to making valuable improvements to their building, and we love seeing healthy communities!


We provide service packages for condominiums, apartments, and commercial buildings as well as offering our expertise for contractors and attorneys in the field.  

Healthy Buildings Lead to Happy Testimonials + Reviews!
