Service Areas We Proudly Serve

Yes, Central Jersey exists — and we work all across it. MSI proudly serves homeowners throughout Hunterdon, Somerset, Morris, and Warren Counties, along with surrounding Central Jersey communities. If pork roll is the right name for breakfast meat and jughandles don’t confuse you, you’re probably in our service area.

From historic homes to new construction, rural properties to busy neighborhoods, our team understands the unique plumbing and remodeling needs of New Jersey homes.
