Client Compliments

  • Elm street builders did a fantastic job renovating my second floor. Despite the many complications of a 200 year old house, the end result is gorgeous and the custom shelving and closets blend perfectly with the original house. I can’t say enough great things about their work.

    They show up when they say they will and they care about their projects. My sister ended up hiring them soon after because she loved how everything came out!

  • I hired Elm Street Builders for a home renovation and they were such a pleasure to work with! The project included replacing 2 bathrooms and the kitchen, replacing the furnace and hot water heater, moving walls to provide more storage space, replacing a few windows, and renewing the finishes throughout.

    Work progressed steadily and was completed to a high standard thanks to Seth's skill at managing the various subcontractors and suppliers effectively. I really appreciated that Seth was conscientious about communication throughout the project; he kept me updated about the construction schedule, offered helpful suggestions or insight on fixtures and finishes, and responded promptly to my calls, texts, and emails.

  • We have been using Elm Street Builders for projects large and small across several properties for almost 10 years. They were introduced to us as "true craftsmen" by the previous owners of our home and they have lived up to that term over and over, particularly on all of the upkeep to our antique property that we prefer to keep true to the originality and time period of the home.

    Seth and his team have done smaller, routine work for us (replaced windows, trim and siding) as well as some larger renovation projects, including a full gut and rebuild of a rental property. We have always been pleased with the quality and results of their work and highly recommend them to all of our friends!

  • Elm Street Builders has completed so many home projects for me over the years since 2011. I am very happy with the high quality of their work. Their craftmanship is top notch. They care about their customers and take pride in their work. They are dependable and highly skilled.

    They solved a major leak problem that I had for my ocean front home that no one else could correct. They did a kitchen remodel and bath remodel plus installed over 25 windows for me, to name a few.

    I would highly recommend them for any building job that you may have.
