Our Founder Jaime Guallpa checking in on the Job

In Business for more than 30 years

MJ and Sons has been going strong for more than 2 decades, with each passing year learning and growing from our experiences with our customers. We’ve started as a small group of experienced workers doing any job that came our way, always showing our best through our work. Ever since then, we’ve been growing both in size and skill, going above the industry standard while still maintaining a positive relationship with our partners and customers with our affordability.

MJ and Sons started out as a family business and continues to be operated by family. Working for more than 30 years has helped us to understand that our customers are also family. We want to make all of our customers feel cared for and heard. We work alongside you and help with any questions you may have before and during the building process. We know how stressful building projects can be, so let us help to relieve that stress, we’ve been doing it for a long time you see.

Our first works were in Scotch Plains and cities around like Plainfield, Westfield, Garwood, Cranford & Kenilworth. Each new project was a challenge, but we are no strangers to a challenge.
