    Bathroom Remodel project

    We hired EHS Maryland to do a complete bathroom remodel. Our old bathroom was gutted down to the studs and completely rebuilt. Mike was great with communication and accommodating with the changes we asked for during the rebuild. The process of obtaining a quote from EHS was great as they provided links to all items that would be used in our project making changes before and during easy. The crew that came to our house everyday was great. We have several more projects that we are planning around our house and will definitely use EHS again.

    Other Residential Remodel project

    EHS did a great job building a roof over our patio. They workers were extremely nice and worked hard to complete the project. Each day they cleaned up so that there were no nails, etc. lying on the patio. Lucas was great to work with, always responsive when we had questions. I would definitely hire EHS again if another project should materialize.

    Retail/Office build out

    EHS did several construction projects (tenant fit outs for retail business and offices) for me already, and I highly recommend them. Nina and Petr are quick, flexible, uncomplicated and I could not be happier.

    Resale Repair List
    $2,200

    I used EHS to complete a repair list for my home sale and I was very happy with the result. They were extremely professional, reasonably priced, and did a beautiful job completing the projects.

    I would use them again!
