    Worked with Valli for more than 2 years on our home build project and they have been nothing but a pleasure to work with. Mike and his team offer knowledge, experience and professionalism and I cannot recommend them highly enough.

    They are a great company to work with and answer all your questions on installing a riser on the septic tank. I highly recommend Valli Construction, they have been around a long time and still provide great service.

    Valli Construction (Portland, CT.) has done the necessary site prep work for a 58’ x 40’ shop building soon to be built in my backyard. Mike (owner), Tom (excavation) and Jackie (office) have been great to work with on this project. They were highly recommended by a long time friend who had the same type of site prep work done many years ago on his 30’ x 60’ shop building. Give them a call, they’ll treat you right!

    Response from the owner

    Thank you for your valuable feedback, Paul! Our team thoroughly enjoyed collaborating with you on your site work project in Colchester, CT. We greatly appreciate you taking the time to write us a review and for providing your recommendation.
