Since 1987, SEI Construction, Inc. has helped Union, Essex, and Morris County homeowners remodel with confidence. We are a family owned and operated business, fully licensed and insured in New Jersey, and our name reflects exactly how we work: Skill, Excellence, and Innovation on every project.
Most remodeling projects fail because of poor planning, unclear timelines, and lack of communication.Â
Our process is built to eliminate all three.
Step 1
Your project starts with a free consultation and detailed quote. We align your vision, goals, and budget, then create a clear plan with defined timelines so you know exactly what to expect from day one.
You start your project with clarity, not uncertainty.
Step 2
We refine your project through collaborative design, material selection, and detailed planning. You receive a transparent proposal outlining scope, pricing, and each phase so there are no surprises before construction begins.
You know exactly what your project includes before construction begins.
Step 3
Your dedicated project manager oversees every detail, keeps the site clean, and stays in regular contact. After completion, we walk through the finished space with you and remain available for ongoing support.
You get a smooth, stress-free build and a finished space that matches your vision.

SEI Construction, Inc. specializes in home remodeling and historic restoration services. Our expertise includes but is not limited to kitchen and bathroom remodeling, basement finishing, room additions, exterior renovations, and historical preservation.
Most bathroom remodels are completed within 3–6 weeks, but the exact timeline depends on the size of the space, the level of renovation, and the materials you choose.
Projects that include major layout reconfigurations, upgraded plumbing, or intricate tile installations may take a bit longer.
Before we begin, we’ll walk you through a clear, customized schedule so you know exactly what to expect from start to finish.
Kitchen remodel timelines can vary widely based on the size of the project and how much the layout is changing. Smaller updates – like new countertops, backsplash, flooring, or swapping out older finishes – typically wrap up in about four weeks.
Larger transformations that involve removing walls, relocating plumbing or electrical, expanding the footprint, or fully redesigning the layout can take anywhere from 12 to 20 weeks, including the design and permitting process.
During your in-home consultation, our team will walk you through a personalized timeline so you know exactly what to expect for your specific project.
