Built Right from the Start

Whether you are upgrading a bathroom, adding a kitchen, finishing a basement, or planning a full remodel, we design and install plumbing systems built to last. Our team collaborates directly with homeowners, designers, and contractors to ensure every line, fixture, and connection is placed with intention.

We install all essential plumbing components, including kitchen sinks, dishwashers, toilets, faucets, ice maker lines, and gas lines, as well as sump pumps and sewage ejector pump systems. Every installation is built around a design plan created specifically for your home's needs, style, and layout.

The result is a system that performs as beautifully as it looks, with the reliability and craftsmanship MSI is known for.

Layout Planning That Works

Good plumbing layout is more than connecting Point A to Point B. It affects water pressure, drainage, venting, noise levels, and long term reliability. We partner with local architects, designers, and project managers to make sure everything flows properly and meets New Jersey code.

We have worked on everything from classic Central New Jersey colonials to brand new construction to, yes, even log cabins. If your project needs a thoughtful, code compliant layout that will last for decades, we are the people you want in the room.


Fixture Selection and Finishes

At our Flemington office we have a small showcase with curated Moen faucet and fixture samples so you can see finishes and styles in person. We can also guide you through choosing quality valves, drains, materials, and accessories that match the performance and durability your home needs.

Whether your style is modern, classic, rustic, or somewhere in between, we help you choose fixtures that look beautiful and stand up to the hard water and heavy usage our area is known for.

How it works

Consultation and Layout Planning

We meet with you, your designer, or your contractor to understand the scope, review the space, and create a plumbing layout that fits your needs and meets code.

02

Fixture and Material Selection

We help you choose the right fixtures, finishes, and materials for durability and style, with samples available at our Flemington office.

03

Rough-In Installation

We install all supply lines, drain lines, venting, and gas lines according to the approved plan and New Jersey plumbing code.

04

Fixture Installation and Testing

Once walls and finishes are complete, we install all fixtures, test every connection, and ensure everything works as designed.

Common questions

Do you help design plumbing layouts for kitchens, bathrooms, and additions?+

Absolutely. We are involved in layout planning every day, partnering with local architects, designers, and project managers to make sure everything flows properly. Good plumbing layout is more than connecting Point A to Point B. It affects water pressure, drainage, venting, noise levels, and long term reliability. We have worked on everything from classic Central New Jersey colonials to brand new construction to, yes, even log cabins. If your project needs a thoughtful, code compliant layout that will last for decades, we are the people you want in the room.

Can you install sinks, faucets, showers, dishwashers, and other fixtures?+

Of course. If water runs to it or drains from it, we install it. This includes sinks, faucets, showers, tubs, dishwashers, garbage disposals, laundry hookups, bar sinks, pot fillers, and anything else you can dream up in your remodel. We install everything safely, correctly, and to New Jersey code so your new fixtures not only look great on day one but continue working the way they should for years to come.

Can you move plumbing to a new location during a remodel?+

Yes, moving plumbing is something we do frequently. Almost anything is possible with the right planning, the right materials, and the right team. Sometimes it is simple, sometimes it requires opening floors or walls and adjusting venting or drain lines. We always look at the structure, the code requirements, the distance, and the best long term solution to make sure the change is worth it. If moving something gives you the layout you really want, we will find the safest and smartest way to make it happen.
