"We recently worked with Metacom to add a mudroom/laundry room onto our house, and I can honestly say the experience was phenomenal. Chris, his brother Derrick, and the entire Metacom team were always pleasant, flexible, and easygoing. As we all know, dealing with contractors nowadays can often be a pain... if you're able to even get in touch with them in the first place, that is. Chris was incredibly responsive throughout the planning and construction process - he made us feel comfortable reaching out with questions/concerns at basically any hour of the day, and would always reply quickly. I cannot say enough good things about Metacom. Hire them with confidence for any of your home projects. You will not be disappointed!"
