Marcel worked efficiently to deliver a high quality finish to our bathroom renovation. He communicated what he was doing at each stage of the renovation and was helpful in sourcing the materials. He worked long hours and always cleared up after himself. Marcel is friendly, honest and hardworking. The quote was very reasonable in comparison to other quotes we received, our first quote was honoured despite the job being more complex than initially anticipated. We will be using Marcel again for other jobs.
