“Assencoa also has his own business, Mark’s Deck Service. Repairing and refinishing decks, he resides in Marlborough with his wife, Robin.”
Yes!!! I would highly recommend Mark’s Deck Service! He and his team did an outstanding job rebuilding my deck that was deteriorating. They removed the old, deteriorating board, replaced problem areas and laid a beautiful Trex board deck with perfect rails, steps and trim. Mark kept me informed at every step and the cost came in within the expected proposal and on time.
Mark and his team did a great job rebuilding my back deck and help us select the best colors. The Deck looks amazing! Mark’s team was fun, professional and friendly!
I would not recommend Mark. He pushed out our job a few weeks last fall and assured us that the temperature was not too cold to apply. We got specs of white paint all over our deck, and nine months later areas of the stain were no longer visible and mildew had taken hold.
I would highly recommend Mark's Deck Service. Mark Assencoa was very courteous and professional and fixed the issue with my deck. His workmanship was superior.
