We had SEI construction for two different projects. First to install a full bathroom on my top floor and another to open a wall on the bottom floor. No problems with either project. They do beautiful work and clean up after — also they show up when they say they will be here.

Who we are
A family owned remodeling company built on three principles
These three words are why the company is named what it is. They describe the experience homeowners have had on every SEI project since 1987.
S - Skill
Every person on an SEI project is selected because they are genuinely excellent at their trade. That means in-house carpentry rather than outsourcing the craftsmanship. It means the specific people our clients mention by name in their reviews – Tyler for his precision, Izzy for working as if it were his own home. Skill means the details most homeowners never notice but that determine whether a renovation holds up for thirty years.
E - Excellence
Excellence at SEI means one thing: the project is not complete until every detail matches the agreement. Not approximately. Not close enough. Jackie Metzger, who hired SEI for three separate projects, said it plainly: “The job is not complete until the last detail has been addressed.” That standard is why clients return.
I - Innovation
Innovation at SEI means finding better ways to plan, communicate, and build so each project runs more smoothly than the last. It means 3D design renderings so you can see your finished space before construction begins. It means the BuildClean professional dust control system so your family can stay home throughout a major renovation. It means a structured design-build process that eliminates the planning failures and communication breakdowns that make most remodeling experiences painful.
In their own words
verified reviews from homeowners who hired SEI Construction, Inc.
Excellent renovation of our very old home, updating while maintaining the beauty and character of the older home. Responsive and easy to contact. Workers were pleasant, friendly, respectful and very nice to our small children. Impeccable and meticulous carpentry.
Read on Houzz →Friendly company. Works with you every step of the way. Handles change requests professionally and promptly. Everyone on the team kept the house and project site clean and organized.
Read on Houzz →I highly recommend SEI Construction for any remodeling needs! Mike Rizzo and his crew designed my kitchen and bathroom and they are stunning! From start to finish they kept in constant communication and were up front about all costs. No question was too small for them. Their work is exquisite — my kitchen and bathroom came out better than I even imagined!
Read on Houzz →We cannot recommend SEI Construction more highly. My wife and I have worked with many contractors as serial renovators and the quality of craft, attention to detail, pace, and the absolutely delightful team of employees that SEI brings to bear is unmatched. SEI is professional and qualified in every sense of the word.
Read on Houzz →We hired Mike and his team to put on an addition to our home in Clark. Although we had a smaller budget than most of Mike's clients, Mike worked within our budget and showed he cared the same for us as the rest of his clients. We highly appreciate the craftsmanship, professionalism, trustworthiness, but most importantly the respect shown for our family.
Read on Houzz →This was the third project and the most extensive project that we hired SEI for. We felt very comfortable working with all his crew, they were easy to communicate with and always kept us up to date on the progress. I especially like Mike's detailed estimates — easy to read and you know exactly what he is going to do. You can depend on Mike to check in at each stage and if you have any issues he addresses them immediately.
SEI has worked for us for many years and we totally rely on Mike's expertise and workmanship, as well as his creativity. He has remodeled our bathrooms, full basement, dining room, kitchen, both studies and family room. His thoughts on design are modern and sleek while keeping the history and period of our house in mind. I totally trust Mike and his crew — to the point that they have total access to our home.
We had SEI Construction do a lot of renovations on our home. Mike and his crew — especially Izzy — worked as if it was their home. From the estimate and meeting with Mike to explain our vision, EVERYTHING was done as promised if not better than we expected! Plus they work clean! Experts in their craft. I cannot rave enough!

Mike and his team did a great job doing whatever they could so the work would not affect our baby or our 4 year old son. We highly appreciate the craftsmanship, professionalism, and trustworthiness.
Read on Google →SEI construction added a net-new master suite, remodeled a full bath, created a net-new full bath in the basement, and redid all HVAC duct work, roofing, and siding. Mike Rizzo was a great communicator — always made technical topics easy to understand. Our project lead Tyler was friendly, funny, and an expert carpenter. There was quality and precision in everything he built. I'm thrilled with the work they did.
SEI redid our outside deck, remodeled a downstairs bathroom and installed composite railing. The team was professional, courteous and responsive, and the fit and finish was excellent. I called them back and they came back and did warranty work at no charge. Very pleased with their response — happy to recommend a local, quality contractor.
We hired SEI through a friend's referral for a bathroom remodel. They are our number one recommendation for attention to detail, friendliness and trust of crew, and responsiveness. They truly want the end result to be great and you can always trust who they bring into your home. I can't recommend them enough.
I'm an interior designer in the area. I've used Mike and his team on countless projects over the past 10 years. His team is always wonderful, trustworthy and meticulous. I thoroughly enjoy working with them and look forward to future projects. I can't believe I haven't written a review sooner!
SEI is the best! Smart, thoughtful, fast and great quality work! We've used other contractors before and SEI is far and away better than anyone else we've worked with. Great attention to detail. I can't recommend them enough!
