Where We Work

What Our Clients Say

Everything you want in a contractor

Ben, Frank and Cheryl were a pleasure to work with on the project. Our plan was to alter a brick wood burning fireplace with a gas insert and to redefine and modernize its appearance and shape. Our first thought was concrete, which proved to be too heavy and expensive. Living Plasters’ suggestion of a finish …

Pride in their craft

We couldn’t be more pleased with our experience with this dynamic team of professionals. We hired them to build out our unfinished 1000 sq. ft. basement. Ben put together a comprehensive estimate, finding competitive bids for the electrical, heating, plumbing, and drywall portions, plus concrete floor stain & polish. We were pleasantly surprised to find …

This was over 3500 sq. ft of floor space with vaulted ceilings, rounded arches, and extensive trim work. The craftsmanship is incredible and the end result was a gorgeous upgrade to our …

Their art is a pleasure

Every day we enjoy the beautiful artistic work Frank, Ben, and Cheryl did plastering the walls and applying the tadelakt technique in our bathroom and along our kitchen counters. Their art is a pleasure for the eyes and to the touch. Tadelakt walls …
